This Week in Brief

Each additional year between migraine onset and trigger-site surgery was associated with 0.34 more headache days per month after operation in a retrospective Plast Reconstr Surg cohort; patients operated on within the 15-year median reached 96% success and 43% complete elimination, against 77% and 15% for those with longer disease. The same journal reports the Awake Integrated Microsurgical approach for head and neck free flaps in frail patients: under regional anaesthesia and sedation, no case converted to general anaesthesia, operative time was shorter (p = 0.001) and no patient needed ICU admission, although the AIM group was older and more comorbid. A J Med Internet Res meta-analysis of AI for detecting compromised free flaps finds a pooled AUC of 0.92, rising to 0.98 for image-based models against 0.79 for non-image models, with GRADE certainty rated low. In JPRAS, a modified great toe wrap-around flap with iliac bone grafting gave stable pinch and grasp in distal digit defects, with mean static two-point discrimination of 8 mm and no significant donor-site complications; five flaps (4.9%) needed re-exploration for vascular compromise. An Aesthet Surg J meta-analysis finds that prophylactic botulinum toxin A narrows postoperative scars (SMD −0.92, moderate certainty), with no added benefit from escalating the dose from 4 to 10 U/cm.

Across the Field
Reconstruction & Microsurgery.

Dental implants placed in fibula, scapula and DCIA flaps showed about 84% three-year survival in a decade-long Int J Oral Maxillofac Surg cohort, with adjuvant radiotherapy and maxillary placement each carrying a roughly threefold hazard of failure. Two further papers in the same journal report that temporal recipient vessels matched cervical vessels with identical 6% revision rates, and that patient-specific plates for ALT plate-only mandibular reconstruction shortened operative time and reduced blood loss, with no plate infections against three for hand-bent plates. A pooled analysis of more than 7,000 DIEP flaps in Plast Surg (Oakv) found no patient-level clinical or anatomic factor that predicted intraoperative venous congestion. In Microsurgery, a venous-supercharged pedicled PTAP-saphenous flap survived completely in 24 of 26 high-risk distal leg, ankle and foot reconstructions (92.3%). A 40-case Symani robot-assisted series in Plast Reconstr Surg Glob Open, spanning 130 anastomoses and nerve coaptations across free flaps, replantation and lymphatic surgery, reported no flap loss or revision.

Hand & Peripheral Nerve.

Soft robotics reaches the brachial plexus in Nat Commun: a pneumatic shoulder-elbow exosuit raised active range of motion by 80–180% in 14 adults with chronic traumatic injury during single-session testing, while lowering muscle activity and perceived effort. Two cost analyses favour moving hand surgery out of the main theatre: a US claims model in Hand (N Y) projects savings of $13–20 million over 10 years per 1,000 annual soft tissue cases shifted to the procedure room, and a Portuguese public-hospital study in Plast Reconstr Surg Glob Open ties WALANT for acute trauma to lower costs, chiefly through avoided admission. Also in Hand (N Y), electrocautery of ganglion remnants trended toward lower recurrence (4.3% vs 9.5%, not significant), and thumb CMC orthoses were associated with median VAS pain falling from 65 to 30 at 3 months, with no gain from longer daily wear.

Burns & Wounds.

Recorded incidence of lower limb necrotising fasciitis in England rose seven-fold between 2002 and 2022, according to a national study in JPRAS; more than 17% of patients underwent amputation and 1-year mortality was 24%. In J Burn Care Res, a 30% TBSA burn in rats blunted clock gene expression in circulating mononuclear cells and skeletal muscle, with no correlation between the two tissues, suggesting blood-based circadian markers may not reflect muscle. A J Diabetes Res review puts trial healing gains for local diabetic foot ulcer adjuncts at 12–33 percentage points over standard care, and a Sleep Breath review cites a doubled risk of poor ulcer healing with high obstructive sleep apnoea risk. The rest of the section is narrative review, including a Plast Reconstr Surg Glob Open prehabilitation guide for pressure ulcer surgery built on 8 weeks of micronutrients, off-loading and at least 30 days of smoking cessation.

Breast.

Shoulder morbidity after reconstruction is quantified in Eur J Surg Oncol: immediate reconstruction carried more frequent range-of-motion limitation than mastectomy alone (41% vs 24%), yet QuickDASH scores were similar and satisfaction was higher. The Ray method of extended ADM wrapping for prepectoral implants, reported in JPRAS, showed 2.2% Baker III/IV capsular contracture at a mean 24 months, with dehiscence and seroma each at 9.1%. A 253-case JPRAS Open series of risk-reducing mastectomy with reconstruction in very-high-risk women recorded a 43% overall complication rate, but only 11% needed reoperation and 3.5% lost the implant. Prior reduction mammoplasty did not significantly raise lactation disorders or mastitis in a multicentre Aesthetic Plast Surg cohort, and composite vascular mapping for superomedial therapeutic mammoplasty with notch-to-nipple distance above 35 cm was associated with 100% nipple-areola viability against 91.5% without it.

Aesthetic.

Preservation rhinoplasty with asymmetric let-down osteotomy corrected about 90% of severe nasal axis deviation at 12 months in Aesthet Surg J, outperforming spreader-based structural correction; a multicentre prospective East Asian series in the same journal reports FACE-Q scores roughly doubling by 36 months after alar arch reinforcement with thin costal cartilage and tip ligament reconstruction. In Plast Reconstr Surg, Mia minimally invasive breast augmentation matched hybrid implant-plus-fat augmentation on satisfaction, with 74% less reported pain and 61% faster recovery over 6 months. A meta-analysis in Aesthet Surg J Open Forum puts delayed inflammatory reactions after hyaluronic acid filler at about 1 in 2,000 patients per year of follow-up, varying by crosslinking technology, and the GENDER-Q face and neck scales met 78–100% of prespecified hypotheses in 4,890 transgender and gender diverse adults. In a rabbit model, polycaprolactone filler (Ellansé-S) raised collagen density by 79% at 12 months before a decline.

Sarcoma & Oncology.

Upper-extremity synovial sarcomas in a 24-year J Cancer Res Clin Oncol cohort more often had positive margins at first resection than lower-extremity tumours (61% vs 14%) but far fewer postoperative complications (13% vs 53%), with R0 eventually reached at both sites. In JPRAS Open, a defect-matched algorithm of skin graft, regional flap or free flap achieved complete closure with survival of every graft and flap in 28 elderly patients with large facial defects after tumour resection. Ultrasound-guided histotripsy produced an identifiable ablation effect in all 45 ex vivo soft tissue tumour specimens tested in Ann Surg Oncol, although the histologic effect varied with tissue structure.

Artificial Intelligence in Surgery.

An AI facial authenticity model in Plast Reconstr Surg flagged digital manipulation of the nasal region in 19.5% of public postoperative rhinoplasty photographs on RealSelf. J Med Internet Res also carries an 8-billion-parameter language model, run locally without fine-tuning, whose cardiac surgery hospital-course summaries 15 cardiac surgeons rated above the 3.0-of-5 acceptability threshold in every quality domain. A Hernia review ties CT morphometrics, including loss-of-domain and sarcopenia measures, to fascial closure and complications in complex ventral hernia repair while judging AI prediction tools insufficiently validated for routine use, and a bibliometric study in Plast Reconstr Surg Glob Open finds craniofacial surgery behind 32 of the 50 most-cited AI papers in the specialty.

Translational & Hallmark Medicine.

Loss of CAVIN1 contributes to keloid fibrosis through a CAVIN1/GAS5 axis acting on TGF-β/Smad signalling, according to a Burns Trauma study in which restoring the protein, including with the repurposed drug vorinostat, reduced skin fibrosis in mouse models. In Nat Commun, engineered macrophage-derived extracellular vesicles carrying anti-TGFβ1 antibodies reduced vitreoretinal fibrosis in female mice by pairing growth-factor blockade with macrophage reprogramming. A second Nat Commun paper shows that focal adhesion tilt falls as substrate stiffness rises, and that curving a rigid surface can reproduce the cellular response to a given stiffness. The remaining two items are reviews of piezoelectric nanofibre dressings and plant-derived exosome-like nanovesicles for wound repair.

Cases.

Microsurgery carries two single-patient reports: totally extraperitoneal robotic DIEP harvest along a 91.6 mm intramuscular perforator course, and a medial femoral condyle free flap closing a 2 × 2 cm anterior septal defect without separate mucosal coverage, with no problems at 18 months. In Hand Surg Rehabil, a herpes zoster-like eruption appeared on a free flap after post-burn hand contracture release; the authors place viral reactivation in the differential alongside vascular compromise. A Curr Oncol report of clamshell en bloc resection for grade III sternal chondrosarcoma achieved R0 margins, but the polypropylene mesh reconstruction was complicated by dehiscence and mesh infection requiring removal, with discharge on postoperative day 66.

Time from Migraine Onset to Surgery Predicts Postoperative Headache Frequency: A Retrospective Cohort Study.

Suggests that a longer interval between migraine onset and trigger-site surgery predicts more residual headache days, with each additional year of disease associated with about 0.34 more headache days per month.
Overview

A retrospective cohort of 54 patients undergoing migraine trigger-site surgery in Taiwan (2019–2024) evaluated whether years from migraine onset to operation predicted postoperative monthly headache frequency, adjusting for age, sex, preoperative frequency, number of trigger sites, and nerve block status.

Key Findings
  • Overall, 87.0% achieved successful treatment (≥50% reduction in monthly frequency) and 29.6% achieved complete elimination; median time-to-surgery was 15 years.
  • Longer time-to-surgery correlated with higher postoperative frequency (ρ = 0.397) and remained an independent predictor on multivariable regression (β = 0.342; 95% CI 0.107–0.577), alongside preoperative frequency.
  • Patients operated on within the 15-year median had a 96% success rate with 43% elimination, compared with 77% success and 15% elimination for longer disease duration (p = 0.047 and p = 0.038).
Caveat

The cohort is small, and the 15-year cutoff came from the cohort median rather than being prespecified, so the borderline dichotomized comparisons need confirmation in larger series.

Beyond finger reconstruction; where the esthetic refinements meet microsurgery.

Suggests that a modified great toe wrap-around flap with iliac bone grafting can restore stable pinch and grasp in distal digit defects with minimal donor-site morbidity, although 4.9% of cases required re-exploration.
Overview

A case series of 103 patients (114 digits) underwent reconstruction with a modified great toe wrap-around flap plus iliac bone graft and full-thickness skin graft donor closure, for thumb defects distal to the MCP joint and finger defects distal to the PIP joint; sensory, functional, and esthetic outcomes were assessed.

Key Findings
  • Five patients (4.9%) required re-exploration for vascular compromise, with one partial flap loss; all remaining flaps survived.
  • At 6 months, mean static two-point discrimination was 8 mm (range 7–10 mm) and the mean Semmes-Weinstein score was 2.83; all digits achieved stable pinch and grasp.
  • Mean iliac bone graft length was 17.7 mm, with resorption in one case over a mean follow-up of 28 months.
  • No significant donor-site complications were observed, including ulceration, delayed healing, persistent pain, cold intolerance, or gait disturbance.
Caveat

This is an uncontrolled series with no comparison to a standard wrap-around or partial toe transfer.

Botulinum Toxin Type A for Postoperative Scar Prevention: A Systematic Review and Meta-analysis.

Suggests that prophylactic botulinum toxin A reduces objective postoperative scar width with moderate certainty, while clinician-rated gains are less certain and higher doses within 4–10 U/cm added no further benefit.
Overview

A systematic review and meta-analysis of 17 comparative trials (456 participants; 656 treatment sites) pooled standardized mean differences for perioperative or postoperative BoNT-A versus control and examined effect modification by injection timing, dose density, and anatomic site.

Key Findings
  • BoNT-A reduced objective scar width (SMD −0.924; 95% CI −1.119 to −0.728; moderate certainty) and improved clinician composite scores (SMD −0.864; low certainty).
  • Pooled clinician-composite analyses showed a larger effect with delayed injection (SMD −1.240) than with immediate injection (SMD −0.559), although direct within-site timing studies conflict.
  • Timing and anatomic site jointly explained 81% of heterogeneity, with the largest effects on the chest and the smallest at fine facial sites.
  • Cross-study dose escalation from 4 to 10 U/cm was not associated with additional benefit, and patient-reported outcomes remained uncertain.
Caveat

The timing and dose comparisons are made across studies rather than randomized within them, and most clinician-rated outcomes carried low or very low certainty, so the optimal injection protocol remains unresolved.

Head and neck free flap reconstruction in frail patients with the Awake Integrated Microsurgical approach.

Suggests that head and neck free flap reconstruction under regional anesthesia and sedation is feasible in frail patients, with no conversions to general anesthesia, shorter operative times, and no ICU admissions.
Overview

A retrospective cohort of 40 patients undergoing extra-oral head and neck free flap reconstruction after oncologic resection compared general anesthesia (n = 20) with the Awake Integrated Microsurgical (AIM) approach using peripheral or neuraxial blocks plus sedation (n = 20).

Key Findings
  • AIM patients were significantly older and more comorbid, yet none required conversion to general anesthesia.
  • Operative time was shorter under AIM (p = 0.001), while ischemia time, transfusion rate, and flap outcomes were comparable.
  • No AIM patient required ICU admission (p = 0.047), and rates of Clavien-Dindo ≥ III complications and total or partial flap loss were similar between groups.
  • Latissimus dorsi and ALT/vastus lateralis flaps made up 85% of reconstructions; in the AIM group, peripheral blocks were used in 90% and neuraxial blocks in 40%.
Caveat

Groups were small and allocated by anesthetic fitness, and the general anesthesia group had more composite bone and soft-tissue defects, which may explain part of the operative-time difference; the study is underpowered for flap loss.

Diagnostic Accuracy of AI in Prediction and Assessment of Compromised Free Flaps: Systematic Review and Meta-Analysis.

Suggests that AI tools, particularly image-based models, detect free flap vascular compromise with high pooled accuracy (AUC 0.98 for image-based models), although the certainty of evidence is low.
Overview

A systematic review and diagnostic accuracy meta-analysis of 18 studies (17 pooled quantitatively) estimated sensitivity, specificity, AUC, and diagnostic odds ratio of AI models for postoperative free flap monitoring and compromise prediction using a hierarchical bivariate random-effects model, with subgroup analyses by modality.

Key Findings
  • Across all models, pooled sensitivity was 0.83 and specificity 0.87, with an AUC of 0.92; prediction intervals were very wide (specificity PI 0.03–1.00).
  • Image-based models outperformed non-image models, with sensitivity 0.92, specificity 0.95, and AUC 0.98 versus 0.69, 0.72, and 0.79.
  • For vascular compromise detection specifically, pooled sensitivity was 0.92 and specificity 0.91.
  • Heterogeneity was substantial, QUADAS-2 flagged methodological concerns in several studies, and GRADE certainty was low.
Caveat

Few models were externally validated and prediction intervals spanned nearly the full range, so pooled accuracy may not transfer to a different unit's flap population or imaging setup.

Head and neck free flap reconstruction in frail patients with the Awake Integrated Microsurgical approach.

Suggests that head and neck free flap reconstruction under regional anesthesia and sedation is feasible in frail patients, with no conversions to general anesthesia, shorter operative times, and no ICU admissions.
Overview

A retrospective cohort of 40 patients undergoing extra-oral head and neck free flap reconstruction after oncologic resection compared general anesthesia (n = 20) with the Awake Integrated Microsurgical (AIM) approach using peripheral or neuraxial blocks plus sedation (n = 20).

Key Findings
  • AIM patients were significantly older and more comorbid, yet none required conversion to general anesthesia.
  • Operative time was shorter under AIM (p = 0.001), while ischemia time, transfusion rate, and flap outcomes were comparable.
  • No AIM patient required ICU admission (p = 0.047), and rates of Clavien-Dindo ≥ III complications and total or partial flap loss were similar between groups.
  • Latissimus dorsi and ALT/vastus lateralis flaps made up 85% of reconstructions; in the AIM group, peripheral blocks were used in 90% and neuraxial blocks in 40%.
Caveat

Groups were small and allocated by anesthetic fitness, and the general anesthesia group had more composite bone and soft-tissue defects, which may explain part of the operative-time difference; the study is underpowered for flap loss.

Time from Migraine Onset to Surgery Predicts Postoperative Headache Frequency: A Retrospective Cohort Study.

Suggests that a longer interval between migraine onset and trigger-site surgery predicts more residual headache days, with each additional year of disease associated with about 0.34 more headache days per month.
Overview

A retrospective cohort of 54 patients undergoing migraine trigger-site surgery in Taiwan (2019–2024) evaluated whether years from migraine onset to operation predicted postoperative monthly headache frequency, adjusting for age, sex, preoperative frequency, number of trigger sites, and nerve block status.

Key Findings
  • Overall, 87.0% achieved successful treatment (≥50% reduction in monthly frequency) and 29.6% achieved complete elimination; median time-to-surgery was 15 years.
  • Longer time-to-surgery correlated with higher postoperative frequency (ρ = 0.397) and remained an independent predictor on multivariable regression (β = 0.342; 95% CI 0.107–0.577), alongside preoperative frequency.
  • Patients operated on within the 15-year median had a 96% success rate with 43% elimination, compared with 77% success and 15% elimination for longer disease duration (p = 0.047 and p = 0.038).
Caveat

The cohort is small, and the 15-year cutoff came from the cohort median rather than being prespecified, so the borderline dichotomized comparisons need confirmation in larger series.

Outcomes of mandibular reconstruction using conventional plates vs patient-specific implants.

Suggests that patient-specific implants for plate-only mandibular reconstruction with ALT flaps shorten operative time and reduce blood loss compared with hand-bent plates, with no plate infections versus three.
Overview

A retrospective cohort of 39 patients with oral malignancy undergoing segmental or hemimandibular resection and anterolateral thigh flap reconstruction over a bridging plate without bone compared patient-specific implants (n = 21) with conventional bent reconstruction plates (n = 18).

Key Findings
  • PSI reconstruction was associated with significantly shorter operative time (P = 0.0002) and lower intraoperative blood loss (P = 0.0039).
  • No plate-related infections occurred with PSI, compared with three in the conventional plate group, over a median follow-up of 1322 days (range 91–3225).
Caveat

The small, non-randomized cohort spans 8 years, so PSI cases likely cluster in the later period with more team experience, and a 0 versus 3 infection difference is too small to test meaningfully.

Outcomes for recipient vessel selection in head and neck free flap reconstruction: a retrospective cohort study.

Suggests that temporal recipient vessels perform comparably to cervical vessels in head and neck free flaps, with identical 6% revision rates and no significant difference in total flap loss (1% vs 5%).
Overview

A retrospective cohort of 158 free flaps at a single center compared 79 flaps anastomosed to temporal recipient vessels with 79 cervically anastomosed flaps from the same period, adjusting for defect location and surgical complexity; primary outcomes were vascular revision and flap survival.

Key Findings
  • Vascular revision occurred in 6% of flaps in both groups (OR 1.00; 95% CI 0.28–3.60).
  • Total flap loss was 1% with temporal and 5% with cervical vessels, a non-significant difference (OR 0.24; 95% CI 0.03–2.20).
  • Operative time was shorter in the temporal group (P < 0.001), with comparable ischemia time.
  • Temporal patients had higher ASA scores (P = 0.009) but no increase in medical complications or resource utilization.
Caveat

Recipient site was chosen by the surgeon according to defect location, and with only five total flap losses the wide confidence intervals cannot exclude a clinically meaningful difference.

Risk factors for dental implant failure in vascularized bone flaps: a decade-long cohort study.

Demonstrates roughly 84% three-year survival for dental implants in fibula, scapula, and DCIA flaps, with adjuvant radiotherapy and maxillary placement each associated with about a threefold higher hazard of failure.
Overview

A retrospective cohort of 105 patients with 358 implants placed in fibula, scapula, or deep circumflex iliac artery free flaps over 10 years at a single institution analyzed implant failure (removal for any reason) using Kaplan-Meier estimates and mixed-effects Cox regression accounting for patient-level clustering.

Key Findings
  • Cumulative implant survival was 93.4% at 1 year, 89.2% at 2 years, and 83.9% at 3 years, remaining relatively stable thereafter.
  • Adjuvant radiotherapy was the strongest independent risk factor for implant failure (HR 3.46; P = 0.009) in the adjusted model.
  • Implants placed in a reconstructed maxilla failed more often than those in the mandible (HR 3.00; P = 0.040).
  • Infection or peri-implantitis caused 68.5% of failures, followed by osteoradionecrosis; donor site and smoking were not associated with failure after adjustment.
Caveat

Residual confounding in this retrospective single-institution cohort may still affect the radiotherapy estimate despite multivariable adjustment.

A defect-oriented decision framework for circumflex scapular artery-based flaps: Insights from a 20-year single-centre clinical experience.

Over 20 years, 83 pedicled circumflex scapular artery-based flaps covered large regional defects with complications in 9 cases, suggesting these flaps are versatile when the transfer pattern is matched to the defect's location.
Overview

This retrospective single-centre cohort of 80 patients (83 flaps, 2005–2025) reviewed pedicled circumflex scapular artery-based reconstructions. It analyzed defect characteristics, flap types, transfer patterns and outcomes, and used them to build a post hoc, defect-oriented framework for choosing the flap.

Key Findings
  • Across 83 flaps, mean defect area was 203.4 cm² and the largest harvested flap measured 720 cm².
  • Three transfer patterns were used: standard island flaps (n = 63) for back, upper extremity and latissimus donor-site defects; island flaps passed through the triangular space (n = 6) for anterior axillary and chest wall defects; and propeller flaps (n = 14) to reduce pedicle tension.
  • Complications occurred in 9 cases (about 11%), mainly vascular compromise and partial flap loss.
  • In axillary reconstruction, shoulder range of motion improved by 65.6 ± 24.1° (P < 0.001).
Caveat

The decision framework was built after the fact from one centre's retrospective experience. It was not tested prospectively or compared with other flap choices, so its value for guiding flap selection is unproven.

A Supercharged Pedicled PTAP-Saphenous Flap for Distal Lower-Limb Reconstruction.

A distally based PTAP-plus-saphenous flap with routine venous supercharging survived completely in 24 of 26 high-risk distal leg, ankle and foot reconstructions (92.3%).
Overview

This retrospective case series of 26 consecutive reconstructions (2010–2025) by one senior surgeon evaluated a distally based posterior tibial artery perforator plus saphenous flap. The flap had planned end-to-end venous supercharging and a temporary skin bridge, and was used in patients at high risk of flap loss (crush or major trauma, older or comorbid patients, long flaps).

Key Findings
  • Complete flap survival occurred in 24 of 26 flaps (92.3%).
  • Venous supercharging used a great saphenous vein branch in 23 flaps and the lesser saphenous vein in 3, joined end-to-end to a superficial vein near the defect.
  • Mean flap size was 5 × 16 cm (up to 20 cm long); the pivot perforator lay a mean 9 cm above the medial malleolus, and the mean arc of rotation was 100°.
  • Trauma accounted for 21 cases, and 18 defects exposed tibia or ankle joint, with tendon exposure in 8.
Caveat

Without a comparison group of non-supercharged reverse-flow flaps, the effect of supercharging on survival cannot be separated out. The mean age of 34 years also fits poorly with the elderly and comorbid patients the technique is said to target.

Expanding the Role of Robot-assisted Microsurgery: Implementation, Challenges, and Outlook From a High-volume Tertiary Care Center.

In 40 consecutive robot-assisted microsurgical cases with 130 anastomoses and nerve coaptations, there was no flap loss or revision, suggesting the Symani system is feasible early on across free flaps, replantation and lymphatic surgery.
Overview

This retrospective single-surgeon series of 40 consecutive procedures (March 2023 to April 2024) described how the Symani Surgical System was introduced for free tissue transfer, acute hand trauma including digital replantation, and lymphatic reconstruction, and reported feasibility and short-term outcomes.

Key Findings
  • The cases comprised 26 free tissue transfers and 14 acute hand trauma cases, including digital replantations; two cases involved lymphovenous anastomoses, done with or separately from lymph node transfer.
  • A total of 130 robot-assisted anastomoses were performed: 43 arterial, 57 venous, 7 vein-to-artery, 4 lymphovenous and 19 nerve coaptations.
  • No flap loss or revisions occurred in the reported short-term follow-up.
  • Mean anastomosis time was 16.4 ± 9.6 minutes; the authors describe longer operative times and higher costs as early barriers that fall with experience.
Caveat

The series has no hand-sewn comparison group and no long-term follow-up. It shows feasibility but cannot show any advantage over standard microsurgery in patency, outcomes or cost.

Evaluation of the Feasibility, Safety, and Effectiveness of a Tailored Enhanced Recovery After Surgery Protocol for Gastroepiploic Vascularized Lymph Node Transfer in Breast Cancer-Related Upper Extremity Lymphedema: A Preliminary Retrospective Comparative Study.

A tailored ERAS pathway for gastroepiploic lymph node transfer was linked to a hospital stay of about 2.3 versus 5.6 days and lower costs, with no apparent loss in limb circumference reduction or quality of life.
Overview

This retrospective comparative study of 45 patients with unilateral stage II–III breast cancer-related arm lymphedema compared two approaches after gastroepiploic vascularized lymph node transfer. The tailored ERAS protocol (n = 29) used early oral intake and mobilization, opioid-sparing analgesia, no nasogastric tube, and decongestive therapy from day 7; the comparison group (n = 16) received conventional perioperative care.

Key Findings
  • Hospital stay was 2.34 versus 5.56 days with ERAS versus conventional care (p < 0.001).
  • Estimated hospitalization costs were €1400 versus €3300 (p < 0.001).
  • Flap survival was 100% in both groups, with no flap-related complications.
  • Circumferential reduction (44.4% vs 47.5%), 12-month LYMQOL scores and yearly infection episodes were comparable between groups.
Caveat

The design was retrospective and nonrandomized with only 16 controls, so it is underpowered to rule out differences in lymphedema outcomes. Group allocation may also have been confounded by treatment period or patient selection.

Intraoperative Venous Congestion in DIEP Flap Reconstruction: A Pooled Analysis Demonstrating the Limited Predictive Value of Patient-Level Risk Factors.

In a multicentre cohort plus a pooled analysis of over 7000 DIEP flaps, no patient-level clinical or anatomic factor significantly predicted intraoperative venous congestion; abnormal venous connections showed the strongest association.
Overview

This multicentre retrospective cohort of 301 patients (411 flaps) from five centres was combined with data from 12 published studies (7189 flaps) in a pooled analysis. It assessed clinical and CT angiographic risk factors for intraoperative venous congestion that needed a secondary venous outflow procedure.

Key Findings
  • Intraoperative venous congestion occurred in 8.8% of flaps (36 events) in the institutional cohort.
  • Diabetes (OR 1.78, 95% CI 0.89–3.59) and prior abdominal surgery (OR 1.32, 95% CI 0.67–2.63) showed nonsignificant trends toward higher risk; smoking, hypertension and preoperative radiation showed no association.
  • Perforator number and superficial inferior epigastric vein diameter were not predictive; thinner flaps trended toward congestion (mean difference -2.40 mm, 95% CI -5.24 to 0.54).
  • Abnormal venous connections, reported in individual studies, showed the strongest association with congestion.
Caveat

The pooled data came from a rapid rather than systematic review, and the studies defined venous congestion differently. With only 36 events in the institutional cohort, the study had little power to detect modest risk factors.

Beyond finger reconstruction; where the esthetic refinements meet microsurgery.

Suggests that a modified great toe wrap-around flap with iliac bone grafting can restore stable pinch and grasp in distal digit defects with minimal donor-site morbidity, although 4.9% of cases required re-exploration.
Overview

A case series of 103 patients (114 digits) underwent reconstruction with a modified great toe wrap-around flap plus iliac bone graft and full-thickness skin graft donor closure, for thumb defects distal to the MCP joint and finger defects distal to the PIP joint; sensory, functional, and esthetic outcomes were assessed.

Key Findings
  • Five patients (4.9%) required re-exploration for vascular compromise, with one partial flap loss; all remaining flaps survived.
  • At 6 months, mean static two-point discrimination was 8 mm (range 7–10 mm) and the mean Semmes-Weinstein score was 2.83; all digits achieved stable pinch and grasp.
  • Mean iliac bone graft length was 17.7 mm, with resorption in one case over a mean follow-up of 28 months.
  • No significant donor-site complications were observed, including ulceration, delayed healing, persistent pain, cold intolerance, or gait disturbance.
Caveat

This is an uncontrolled series with no comparison to a standard wrap-around or partial toe transfer.

Supporting upper limb movements with a soft robot after a brachial plexus injury.

In single-session testing of 14 adults with chronic traumatic brachial plexus injury, a soft pneumatic shoulder-elbow exosuit increased active range of motion by 80–180% and reduced muscle activity and perceived effort.
Overview

This single-session experimental study of 14 adults with chronic traumatic brachial plexus injury (six complete lesions, ten after nerve transfer) tested a soft wearable exosuit. The suit uses pneumatic actuation and inertial sensing to assist the shoulder and elbow, and arm function was compared with and without it.

Key Findings
  • Active range of motion increased by 80–180% and static endurance by 160% with the device.
  • Muscle activity fell by 30–60%, with perceived effort reduced to near zero and less fatigue.
  • Participants kept a moderate-to-high sense of agency over their movements and reported good satisfaction with the device.
  • In a subset of four participants, Action Research Arm Test scores improved by a mean of 4.5 points, and movements became smoother and less compensatory.
Caveat

Benefits were measured only while wearing the device in a single session, with functional testing in just four participants. Durability, home usability and any carryover to unassisted function remain unknown.

More Than Worth It: The Economic Impact of Shifting Soft Tissue Hand Procedures From the Operating Room to the Procedure Room.

In a US national claims analysis, moving common soft tissue hand procedures from the operating room to the procedure room was projected to save $13–20 million or more over 10 years per 1000 cases a year, mainly by eliminating facility fees.
Overview

This national administrative claims database cost analysis compared payer reimbursements and day-of-surgery and 90-day costs for common soft tissue hand procedures done in the procedure room versus the operating room, with or without anesthesia. It also modeled 10-year savings from shifting 1000 cases per year to the procedure room.

Key Findings
  • Surgeon reimbursement was higher in the procedure room than in the OR with anesthesia, by +24.2% to +85.7% (De Quervain release to endoscopic carpal tunnel release).
  • Compared with the OR without anesthesia, surgeon reimbursement in the procedure room was 9.8% to 75.3% higher, with the same two procedures at either end of the range.
  • Day-of-surgery costs were much lower in the procedure room, driven by elimination of the facility fee.
  • Projected 10-year savings for 1000 cases per year exceeded $20 million for OR cases with anesthesia and ranged from $13 million to $20 million for OR cases without anesthesia.
Caveat

Savings are modeled from the payer's side using US claims data. They leave out the practice's cost of setting up procedure rooms.

WALANT Versus Sedation for Hand Trauma: A Comparative Cost Analysis in a Portuguese Public Hospital.

In a Portuguese public hospital, a WALANT-based pathway for acute hand and wrist trauma was linked to lower hospital costs than conventional anesthesia, mainly by avoiding hospital admission.
Overview

This retrospective observational study of 99 patients having surgery for acute hand or wrist trauma over 2 years compared hospital costs between WALANT (n = 49) and conventional anesthesia (n = 50). Costs were adjusted for age and diagnostic group, and a sensitivity analysis was restricted to controls judged eligible for WALANT.

Key Findings
  • Adjusted analyses showed lower total costs with WALANT.
  • Savings came mainly from avoiding hospital admission, with smaller contributions from a smaller surgical team and no routine preoperative tests.
  • Among controls retrospectively judged eligible for WALANT, lower total and direct costs and shorter length of stay remained significant.
  • A hypothetical model suggested further potential savings if WALANT were used more widely.
Caveat

Anesthesia type followed routine practice rather than randomization, so case complexity likely differed between groups. Adjusting only for age and diagnostic group may not remove this confounding.

The Role of Electrocauterization in Preventing Ganglion Recurrence: Evaluating Adjuncts to Standard Surgical Excision.

Electrocautery of ganglion remnants after open excision showed a non-significant trend toward lower recurrence (4.3% vs 9.5%), with no recurrences when cautery was combined with tissue window excision.
Overview

A retrospective cohort of 181 patients (189 cysts) undergoing open ganglion excision by two surgeons between 2018 and 2024 compared recurrence after electrocauterization of cyst remnants (113 patients, 116 cysts) versus no cauterization (68 patients, 73 cysts). A secondary analysis examined cautery combined with tissue window excision or capsular closure.

Key Findings
  • Recurrence occurred in 4.3% of cauterized versus 9.5% of non-cauterized cysts (5/116 vs 7/73), a difference that did not reach statistical significance.
  • Cauterization combined with tissue window excision produced zero recurrences in 31 cysts, compared with 1 recurrence in 12 non-cauterized window excisions.
  • Capsular closure alone was associated with higher recurrence (6/44), with 2/7 recurrences when closure was combined with cauterization; the authors hypothesize that leaving the capsular defect open permits continuous drainage of residual fluid.
  • Recurrences predominantly involved dorsal cysts (69%); 46% of recurrent cysts were under 2 cm, and patients with manual occupations were frequently affected.
Caveat

Technique choice was not randomized and the subgroups are very small (for example, 7 closures with cautery), so the event counts cannot separate the effect of cautery from window excision or surgeon preference.

Association Between Orthotic Wear Duration and Pain Reduction in Thumb Carpometacarpal Osteoarthritis.

Orthosis use for thumb CMC osteoarthritis was associated with pain falling from a median VAS of 65 to 30 at 3 months, but longer daily wear time was not associated with greater pain reduction.
Overview

A retrospective cohort of 56 patients (63 thumbs) with thumb carpometacarpal osteoarthritis treated with an orthosis was assessed at baseline and 3 months. Linear mixed-effects models tested whether self-reported average daily wear time modified change in pain (100-mm VAS) and function (HAND20), adjusting for age, sex, and radiographic severity.

Key Findings
  • Median VAS pain improved from 65 at baseline to 30 at 3 months (P < .001).
  • HAND20 function scores improved significantly over the same interval, whereas pinch strength showed no significant change.
  • Time-by-wear-duration interactions were not significant for either VAS or HAND20, giving no evidence that longer daily wear produced larger improvements.
  • The authors interpret the findings as suggesting that appropriate, activity-specific use may matter more than maximizing total daily wear time.
Caveat

Wear time was recalled by patients at the 3-month visit rather than objectively measured, and without an untreated comparison group the pain improvement cannot be separated from natural fluctuation or regression to the mean.

Radiographic Outcomes of Distal Radial Fractures in Patients Older Than 90 Years: Preoperative and Postoperative Correlations.

Surgical fixation of distal radius fractures in patients aged 90 and older maintained radiographic alignment, with a mean final DASH of 29 and a 15% complication rate in this selected series.
Overview

A retrospective case series of 73 patients aged 90 years or older (mean age 92, 89% women) who underwent operative treatment of distal radius fractures assessed dorsal tilt, ulnar variance, radial inclination, and radial height preoperatively, immediately postoperatively, and at final follow-up. Radiographic parameters were correlated with DASH and VAS pain scores at final follow-up, and complications and reoperations were recorded.

Key Findings
  • Dorsal tilt, ulnar variance, radial inclination, and radial height all improved postoperatively and were maintained at a mean final follow-up of 4.1 months.
  • The mean final DASH score was 29, and preoperative radiographic alignment showed no significant correlation with final function.
  • Only immediate postoperative radial height showed a weak correlation with final DASH score.
  • Minor and major complications combined occurred in 15% of patients (n = 11).
Caveat

Without a nonoperative comparison group and with a mean follow-up of about 4 months, the series cannot show that surgery outperforms casting in nonagenarians or capture longer-term outcomes.

[Ulnar carpometacarpal joint fracture luxation of fourth and fifth ray].

This review describes ulnar CMC fracture-dislocations of the fourth and fifth rays as frequently missed on plain radiographs and recommends early CT and, in most cases, surgical fixation tailored to the injury pattern.
Overview

A review (German-language) summarizes the epidemiology, diagnosis, injury patterns, operative management, and outcomes of carpometacarpal fracture-dislocations of the fourth and fifth rays.

Key Findings
  • Affected patients are predominantly young men, with a high proportion of injuries caused by punching.
  • Nonspecific clinical signs and poor visualization on conventional radiographs create a substantial risk of delayed diagnosis, which appears to be associated with inferior outcomes; early CT is considered essential when injury is suspected.
  • The fifth metacarpal is consistently involved, and the fourth metacarpal and hamate are frequently injured, either alone or in combination.
  • Conservative treatment appears sufficient only rarely; surgical fixation, ranging from transfixing or reduction K-wires to screw or plate osteosynthesis, is generally preferred and yields favorable outcomes, with salvage procedures available for symptomatic post-traumatic arthritis.
Caveat

The authors acknowledge that robust long-term evidence on functional limitations and post-traumatic osteoarthritis remains limited, leaving the durability of the generally favorable surgical outcomes open.

Dupuytren's disease cords are weakened ex vivo by injection of recombinant collagenase G - A proof-of-concept study.

In a six-cord ex vivo pilot, injection of recombinant collagenase G reduced the force needed to rupture Dupuytren cords by about 32% compared with buffer injection.
Overview

An ex vivo proof-of-concept study of 6 cords from 5 patients injected surgically excised Dupuytren cords with 0.5 mL of recombinant collagenase G (ColG) expressed in Escherichia coli (4 mg/mL; n = 4) or phosphate-buffered saline (n = 2). After incubation at 37 °C, cords underwent tensile testing to rupture on an Instron system.

Key Findings
  • Mean maximum rupture force was about 32% lower with ColG than with PBS (0.047 vs 0.069 kN).
  • Force-displacement curves of ColG-treated cords showed a reduced slope and lower peak force before rupture, consistent with collagenolytic activity.
  • The authors frame the results as pilot data, with dose-response, formulation, exposure time, and safety still to be defined relative to current collagenase-based treatment.
Caveat

With four treated and two control cords, the 32% difference could reflect cord-to-cord variability, and ex vivo mechanics do not establish clinical efficacy or safety.

The radial nerve bridging plate technique for humeral shaft fractures: an approach facilitating plate removal without impeding fracture union - a case series.

With the radial nerve bridging plate technique, none of 11 plate removals caused iatrogenic radial nerve palsy, although 7 of 41 patients developed temporary palsy after the index fixation, all of which recovered.
Overview

A single-center retrospective case series of 48 patients treated between 2013 and 2025 with a radial nerve bridging plate (RNBP) for humeral shaft fracture or nonunion assessed iatrogenic radial nerve palsy (iRNP) after plate removal as the primary outcome. Secondary outcomes were iRNP, malunion, and nonunion after the primary operation, over a mean follow-up of 24 months.

Key Findings
  • Among the 11 patients who underwent plate removal, no iRNP occurred.
  • Of 41 patients without a fracture-related palsy, 7 (17%) developed temporary iRNP after primary fixation; all fully recovered at a mean of 12.3 weeks (range 1–32).
  • There were three nonunions, including one pathological fracture and one surgical neck nonunion in a multilevel fracture.
Caveat

Only 11 plates were removed, so zero palsies remains compatible with a true risk of up to about 28%, and there is no comparison group of conventionally placed plates.

Epidemiology of lower limb necrotising fasciitis in England: A national study (2002-2022).

Recorded incidence of lower limb necrotising fasciitis in England rose seven-fold over 20 years, with over 17% of patients undergoing amputation and 1-year mortality of 24%.
Overview

A retrospective population-based cohort of 2512 patients identified from Hospital Episode Statistics for England (2002–2022) using ICD-10 and OPCS-4 codes described the incidence, demographics, comorbidities, deprivation, and outcomes of lower limb necrotising fasciitis.

Key Findings
  • Incidence increased seven-fold, from 0.1 to 0.8 per 100,000, with most cases occurring in patients over 40 years.
  • More than one-third of cases arose in the most socially deprived quintile, and 55% of patients had severe comorbidities.
  • Morbidity was substantial, with over 17% of patients requiring limb amputation.
  • Mortality was 12.6% at 30 days, rising to 17.4% at 90 days and 24% at 1 year.
Caveat

The analysis relies on administrative coding, so the rising incidence may partly reflect better recording and coding practice rather than a true increase in disease, as the authors acknowledge.

[Complicated wound healing : Current therapeutic concepts].

This review outlines a stepwise algorithm for chronic wounds that starts with diagnosing and treating the underlying cause before local measures aimed at secondary closure.
Overview

A review (German-language) summarizes current therapeutic concepts for difficult-to-heal and chronic wounds and gives an overview of the mechanisms and evidence for newer local wound treatments.

Key Findings
  • Management follows an algorithm in which diagnosis and treatment of the underlying cause of impaired healing come first.
  • Local therapy aims to create a physiological, stage-adapted wound environment through wound cleansing to treat local infection, exudate management, and stabilization of the surrounding skin.
  • The algorithm ends in secondary wound closure, and the authors also summarize the mode of action and evidence for current innovations in local wound therapy.
Caveat

As a review, its algorithm and overview of newer local treatments draw on previously published evidence. How firmly each individual innovation can be recommended depends on the quality of the studies behind it.

A Narrative Review of Local Therapies in Diabetic Foot Ulcers: Promises, Limitations and Unmet Needs.

Suggests that several local adjuncts improve healing in selected diabetic foot ulcers, with trial healing gains of roughly 12–33 percentage points over standard care, although none replaces debridement, offloading, infection control and vascular care.
Overview

This narrative review of 41 publications, including 18 randomised trial reports, synthesises evidence for seven local DFU therapies: leucocyte-platelet-fibrin patches, placenta-derived products, sucrose octasulfate dressings, fish skin matrices, hyperbaric oxygen, topical oxygen and negative pressure wound therapy.

Key Findings
  • A meta-analysis of 11 placental-product trials reported complete healing in 66.9% versus 34.1% with standard care (risk ratio 2.00).
  • Pivotal single-product trials reported absolute healing gains of 12–18 percentage points: leucocyte-platelet-fibrin patch 34% vs 22% at 20 weeks, sucrose octasulfate (EXPLORER) 48% vs 30% at 20 weeks, and intact fish skin in deep ulcers (ODIN) 44% vs 26% at 16 weeks.
  • Topical oxygen showed pooled benefit (risk ratio 1.59), whereas HBOT trials were discordant and NPWT evidence was clinically supportive but of low certainty.
  • Trials commonly excluded severe infection, osteomyelitis and critical ischaemia, leaving complex ulcers largely unstudied.
Caveat

This is a narrative synthesis of separate product trials, so the reported healing rates cannot be used to rank the products against one another.

Prehabilitation for Pressure Ulcer Surgery: A Practical and Evidence-based Guide.

Suggests that an 8-week micronutrient course, pressure off-loading, at least 30 days of smoking cessation and tailored conditioning may improve readiness and outcomes in pressure ulcer reconstruction, based on a narrative synthesis rather than new outcome data.
Overview

Hauc and Janis conducted a narrative evidence synthesis of guidelines, randomised trials, observational studies and expert consensus on perioperative optimisation for pressure ulcer reconstruction, translating it into a practical prehabilitation framework across nutritional, mechanical and functional domains.

Key Findings
  • An 8-week course of vitamins A, B9, C and E with zinc, selenium and copper was associated with improved outcomes after reconstruction.
  • Albumin and prealbumin alone were considered insufficient markers; the NUTRIC score, dietary intake evaluation and body composition analysis gave more accurate nutritional risk stratification.
  • Off-loading surfaces reduced shear and improved tissue perfusion, and smoking cessation for at least 30 days improved vascular and immune recovery.
  • In ambulatory patients, metabolic equivalents below 4 identified higher perioperative risk, and physical therapy-based prehabilitation improved functional capacity.
Caveat

The framework rests on a narrative synthesis of guidelines, randomized trials, observational studies and expert consensus, with its benefits reported as associations. Whether the full prehabilitation bundle reduces complications and recurrence after pressure ulcer reconstruction remains open.

Severe burn disrupts tissue-specific clock gene expression in peripheral blood mononuclear cells and skeletal muscle in a rodent model.

In a rat model, a 30% TBSA burn blunted clock gene expression in circulating immune cells and skeletal muscle, with no correlation between the two tissues, suggesting that blood-based circadian markers may not reflect muscle.
Overview

This randomised animal study of 24 rats compared 30% TBSA scald burn with sham, sampling at four time points on post-burn days 2–3 to measure core clock genes in PBMCs and gastrocnemius muscle alongside markers of atrophy, autophagy, apoptosis and proliferation.

Key Findings
  • Sham animals showed time-of-day variation in PBMC clock genes, whereas burned animals had significantly reduced Clock, Cry1, Cry2, Per1 and Per2 expression.
  • In gastrocnemius muscle, burn suppressed Cry1 and Per2 and increased the atrophy genes Fbxo32 and Trim63.
  • Protein changes were time-dependent: LC3 rose at 12:00 and 00:00, PCNA fell at 06:00, and caspase-3 and LC3 rose together at 12:00, consistent with transient apoptosis and autophagy.
  • Paired PBMC and muscle clock gene expression showed no significant correlation for any gene analysed.
Caveat

With 24 male rats split across two groups and four time points, each group-by-time cell likely held only about three animals, and an 18-hour sampling window cannot fully characterise circadian rhythms.

Vitamins and Chronic Wounds: How Altered Pharmacokinetics and Comorbidities Contribute to Vitamin Deficiencies.

Suggests that vitamin deficiencies are common in chronic wounds and that medication, malabsorption, inflammation, obesity and renal insufficiency may raise vitamin requirements, which could explain inconsistent supplementation trials.
Overview

This review examines how medication, malabsorption, inflammation, overweight, obesity and renal insufficiency alter vitamin pharmacokinetics and requirements in patients with chronic wounds, and offers provisional recommendations for treating and preventing deficiencies.

Key Findings
  • Vitamin deficiencies are prevalent in chronic wound populations, yet supplementation trials have produced inconsistent effects, which the authors attribute partly to suboptimal study designs and doses.
  • Several co-existing factors can alter vitamin kinetics, with diabetes and advancing age acting as overarching drivers of medication use, malabsorption, inflammation and renal insufficiency.
  • Limited evidence points to higher vitamin requirements in diabetes; data on treating combined deficiencies and on B-vitamins are entirely lacking.
  • The authors propose that monitoring blood vitamin concentrations may be warranted given the prevalence and risk factors for deficiency.
Caveat

The recommendations are explicitly provisional and rest on limited pharmacokinetic data, with no trial evidence yet establishing optimal vitamin doses in chronic wound patients.

Antimicrobial Strategies for Chronic Cutaneous Ulcers: From Preclinical Nanotechnology to Clinical Practice.

Suggests that adjuncts such as low-intensity ultrasound, microcurrent, photodynamic therapy and oxygen may aid chronic ulcer healing, while multifunctional antibiofilm nanoplatforms remain at the preclinical stage.
Overview

This review combines clinical evidence on adjunct therapies with preclinical nanoplatform data for chronic cutaneous ulcers, organised around biofilm ecology and antimicrobial resistance.

Key Findings
  • Chronic cutaneous ulcers affect an estimated 1–2% of the population in high-income countries, and standard care fails in many cases complicated by polymicrobial biofilm and resistance.
  • Clinical adjuncts (low-intensity ultrasound, electrical microcurrent, photodynamic therapy, regenerative biomaterials, oxygen-based and advanced topical therapies) may improve contraction, microbial burden, pain and repair when added to standard care.
  • In preclinical models, metallic, polymeric, inorganic and hybrid nanoplatforms target resistant bacteria and biofilms while promoting angiogenesis and matrix remodelling.
  • Clinical evidence remains inconsistent, with small cohorts and non-standardised protocols across modalities.
Caveat

The nanotechnology evidence is entirely preclinical, and the clinical value of these platforms is not established.

Leg Ulcers in Thalassaemia: A Comparative Retrospective Review of Transfusion-Dependent and Non-Transfusion-Dependent Patients.

In a small series of 12 patients, leg ulcers in transfusion-dependent thalassaemia were larger and resolved slightly less often than in non-transfusion-dependent disease (71% vs 80%), despite regular transfusion and chelation.
Overview

This retrospective review of 12 patients with beta thalassaemia and leg ulcers at a tertiary centre compared seven transfusion-dependent with five non-transfusion-dependent patients across demographics, haemoglobin, ferritin, foetal haemoglobin, comorbidities and ulcer characteristics.

Key Findings
  • Transfusion-dependent patients were younger (mean 31.9 vs 44.0 years), predominantly male, and had larger ulcers (mean 3.1 cm²), whereas non-transfusion-dependent patients had more episodes (mean 2.2).
  • Transfusion-dependent patients had higher ferritin, while non-transfusion-dependent patients had higher foetal haemoglobin and slightly better resolution (80% vs 71%).
  • Splenectomy had been performed in all transfusion-dependent patients and most non-transfusion-dependent patients.
  • Chronic anaemia, iron overload, trauma and hypercoagulability were identified as exacerbating factors; higher foetal haemoglobin and hydroxyurea use, occasional transfusion and early conservative wound care appeared protective.
Caveat

With 12 patients, the group differences rest on very small numbers (resolution was 4 of 5 versus 5 of 7 patients) and cannot establish true risk or protective factors.

The impact of obstructive sleep apnea on skin wound healing - from preclinical perspective to clinical evidence: A narrative review.

Suggests that obstructive sleep apnoea may impair wound healing through intermittent hypoxia and associated comorbidities; in diabetic foot ulcers, high OSA risk doubled the risk of poor healing, although clinical data remain sparse.
Overview

This narrative review of preclinical and clinical studies (PubMed/MEDLINE, Scopus and Web of Science through August 2026) examines how OSA-related intermittent hypoxia may impair skin wound healing directly and indirectly through diabetes, hypertension and obesity.

Key Findings
  • OSA affects nearly one billion adults, up to 80% undiagnosed, and its cyclic desaturation-reoxygenation activates pathways distinct from acute or chronic hypoxia, including sustained inflammation, sympathetic activation and endothelial dysfunction.
  • Preclinical data, mostly from in vitro scratch assays, show that intermittent hypoxia delays wound closure, downregulates HIF-2α and VEGF and shifts macrophages toward a pro-inflammatory phenotype.
  • In diabetic foot ulcers, high OSA risk was associated with a doubled risk of poor healing; improved healing after CPAP has been described only in a small case series.
Caveat

The clinical evidence is limited and heterogeneous, and improved healing after CPAP has been described only in a small case series, so a causal or treatable link has not been demonstrated.

Expanded prepectoral implant-based breast reconstruction: Long-term outcomes of the ray method.

The Ray method of extended ADM wrapping for prepectoral reconstruction showed 2.2% Baker III/IV capsular contracture and 1.3% implant failure at a mean follow-up of 24 months, with wound dehiscence and seroma each at 9.1%.
Overview

This retrospective single-arm series of 224 patients (232 breasts) reports per-breast complications after skin- or nipple-sparing mastectomy with immediate prepectoral implant reconstruction using the Ray extended ADM configuration (2020–2023), over a mean follow-up of 24.3 months.

Key Findings
  • Wound dehiscence and seroma each occurred in 9.1% of breasts, with major seroma in 3.0%.
  • Flap necrosis, hematoma and infection each occurred in under 1% of breasts (0.4%, 0.9% and 0.9%, respectively).
  • Clinically significant Baker grade III/IV capsular contracture was observed in 2.2% of breasts.
  • Implant failure occurred in 1.3% (3 breasts), and no implant rupture was recorded during follow-up.
Caveat

Without a comparison group and with follow-up as short as 6 months in some patients (mean about 2 years), it is unclear whether the Ray method outperforms standard prepectoral ADM techniques, and late capsular contracture may be underestimated.

Shoulder function after mastectomy with and without breast reconstruction: Balancing aesthetic benefit and functional cost.

Immediate breast reconstruction was associated with more shoulder pain and more frequent range-of-motion limitation than mastectomy alone (41% vs 24%). Validated QuickDASH disability scores were similar in both groups, and satisfaction was higher after reconstruction.
Overview

This prospective multicenter study of 329 women compared shoulder function after oncologic mastectomy alone (n = 163) with mastectomy plus immediate, mostly implant-based reconstruction (n = 166). Pain (VAS), range of motion (ROM), QuickDASH, an exploratory shoulder function score (SFS) and satisfaction were measured at each patient's last available visit, 12–82 months after surgery.

Key Findings
  • Reconstruction was associated with more frequent ROM limitation (41.0% vs. 23.9%), more SFS-defined functional limitation (39.2% vs. 27.6%) and higher mean VAS pain (2.19 vs. 1.39; p = .004).
  • Validated QuickDASH scores were comparable between groups (14.98 vs. 12.55; p = .170). The exploratory SFS rated impairment as minimal in 93.4% of reconstructed patients and 95.7% of mastectomy-only patients.
  • Among reconstructed patients, radiotherapy and hormonal therapy were associated with higher exploratory SFS values (p = .012 and p = .018). Leaner patients (BMI ≤25 kg/m²) also scored higher after reconstruction.
  • Patient satisfaction was higher after reconstruction (82% vs. 63%; p < .001), even though pain and ROM limitation were more common in this group.
Caveat

Only one assessment per patient was analyzed, at follow-up ranging from 12 to 82 months, so the study cannot show how shoulder function changes over time. The reconstruction group was also mostly implant-based.

Does History of Reduction Mammoplasty Predispose to Lactation Complications? A Multicenter Retrospective Cohort.

Prior reduction mammoplasty was not associated with a significant increase in lactation disorders, breast infection or mastitis in the year after delivery. Antibiotic prescriptions and emergency department visits were modestly more frequent (HR 1.20 and 1.38).
Overview

This propensity-matched retrospective cohort of 2,206 women from the TriNetX network compared 1,103 patients who gave birth after reduction mammoplasty with 1,103 who gave birth without prior aesthetic breast surgery. The primary outcome was breastfeeding-related complications within one year of delivery.

Key Findings
  • Risk of lactation disorders was not significantly increased after reduction mammoplasty (HR 1.41; CI 0.87–2.27; p = 0.16).
  • Rates of breast infection (HR 0.67; CI 0.39–1.16) and mastitis (HR 0.60; CI 0.31–1.15) were comparable between groups.
  • Prior reduction was associated with more antibiotic prescriptions and emergency department visits (HR 1.20, CI 1.05–1.37; and HR 1.38, CI 1.13–1.67).
Caveat

Outcomes come from diagnosis and prescription codes. The wide confidence interval for lactation disorders (upper limit HR 2.27) does not rule out a meaningful increase.

Preoperative composite vascular mapping in superomedial therapeutic mammoplasty for patients with more than 35 CM sternal notch to nipple distance.

In superomedial-pedicle therapeutic mammoplasty with a sternal notch-to-nipple distance over 35 cm, preoperative composite vascular mapping was associated with 100% nipple-areola complex viability, versus 91.5% without mapping, and with shorter operative time.
Overview

This retrospective cohort of 121 breast cancer patients had superomedial pedicle therapeutic mammoplasty with a sternal notch-to-nipple (SN-N) distance over 35 cm. It compared preoperative composite vascular mapping (n = 62) with conventional planning based on anatomical landmarks (n = 59), assessing operative time, nipple-areola complex (NAC) viability, complications and patient-reported satisfaction.

Key Findings
  • NAC viability was 100% with mapping versus 91.5% without (p = 0.025). Wound-healing complications occurred in 0% versus 8.5%.
  • Mean operative time was shorter with mapping (86.2 vs. 101.2 minutes; p < 0.001). The only baseline difference was age: the mapping group was older (58.4 vs. 54.3 years).
  • Satisfaction with the nipples was higher in every category in the mapping group, including position, alignment, shape, appearance and sensation (p = 0.001–0.049).
Caveat

Patients were not randomized to mapping, so changes in practice over time or surgeon learning curve may explain part of the difference. The NAC result rests on only about five events in the control group.

From Surveillance to Intervention in Breast Cancer-Related Lymphedema: Clinical Thresholds, Longitudinal Monitoring, and Actionable Care Pathways.

The review suggests that a rise of at least 6.5 units in the bioimpedance lymphedema index, or a 5–10% increase in relative limb volume, each measured against the patient's own baseline, works best as a trigger for confirmatory assessment and early conservative care rather than as a standalone diagnosis of breast cancer-related lymphedema.
Overview

This systematic review of 57 studies, searching PubMed/MEDLINE, Embase, Cochrane, KoreaMed and KMbase through March 2026, examined breast cancer-related lymphedema (BCRL). It covered diagnostic methods, intervention thresholds, patient self-monitoring and prospective surveillance, focusing on how surveillance measurements should lead to clinical action.

Key Findings
  • Serial bioimpedance spectroscopy and limb-volume assessment, each compared with the patient's own baseline, were the most thoroughly studied methods for detecting meaningful change before overt BCRL.
  • A lymphedema index rise of at least 6.5 units, or a relative limb-volume increase of 5–10%, was best interpreted as a trigger for confirmatory assessment and early conservative treatment, not as a diagnosis on its own.
  • Ultrasonography and indocyanine green lymphography added complementary tissue and anatomical information but were better suited to selected assessment than to routine surveillance.
  • Evidence supporting patient self-monitoring and health-system implementation remained limited. The authors propose a care pathway that links baseline-referenced monitoring to confirmation, intervention and reassessment.
Caveat

The proposed care pathway is a synthesis and has not been tested prospectively.

"Nipple-centered customized skin expansion for breast reconstruction in female patients with Poland syndrome: A reproducible protocol".

In 24 women with Poland syndrome, nipple-centered customized tissue-expander positioning lengthened the affected-side sternal notch-to-nipple distance from about 16 to 19 cm. Higher BMI was associated with more residual asymmetry.
Overview

This retrospective observational series of 24 women with Poland syndrome evaluated two-stage alloplastic breast reconstruction performed between 2012 and 2023. Anatomical tissue expanders were positioned individually to reshape the skin envelope and correct vertical and horizontal nipple-areola complex (NAC) malposition, with measurements taken before and after surgery.

Key Findings
  • Affected-side sternal notch-to-nipple distance improved from 16.0 to 19.1 cm on average, reflecting correction of vertical NAC position.
  • Midsternal line-to-nipple distance improved from 8.8 to 11.1 cm on average, correcting horizontal NAC position on the affected side.
  • In an exploratory analysis, higher BMI was associated with more residual sternal notch-to-nipple asymmetry after surgery.
Caveat

This retrospective series of 24 women has no comparison group, which leaves open whether customized expander positioning corrects nipple-areola malposition better than conventional expander placement.

"Simultaneous bulge repair and recontouring after abdominally based breast reconstruction: A well-fixed open transversus abdominis release approach".

Open transversus abdominis release with a large, well-fixed polypropylene mesh resolved bulge symptoms in all 11 patients treated after abdominally based breast reconstruction, with no clinical recurrences over about one year of follow-up.
Overview

This retrospective single-surgeon case series of 11 patients describes open transversus abdominis release (TAR) with a large, well-fixed polypropylene mesh to repair abdominal bulge after abdominally based breast reconstruction (ABBR), performed between 2020 and 2025. Mean age was 58 years and mean BMI 29.3 kg/m².

Key Findings
  • All patients reported complete resolution of bulge symptoms, with no clinical recurrence at a mean follow-up of 379 days.
  • Five of the 11 patients had failed a previous bulge repair before TAR: onlay mesh with plication in three and plication alone in two.
  • Bulges appeared a mean of 127 days after ABBR, and the repair used polypropylene mesh with a mean width of 17.6 cm.
  • Reported complications were one seroma and one focal, superficial delay in wound healing, which resolved without treatment.
Caveat

The series has only 11 patients from one expert surgeon and about one year of follow-up. How durable the repair is, and whether other surgeons can reproduce it, remains uncertain.

Use of the same donor site after prior muscle-sparing latissimus dorsi flap for salvaging implant-based reconstructive failures.

In seven patients, residual back tissue left after a previous muscle-sparing latissimus dorsi flap was harvested a second time to salvage radiated implant-based reconstructions. This suggests a muscle-sparing first harvest may keep the latissimus available as a later salvage option.
Overview

This single-surgeon case series of 7 patients describes a second harvest of residual skin and latissimus muscle from the same donor site after a previous muscle-sparing latissimus dorsi (MSLD) flap. The second flap was used to salvage radiated implant-based breast reconstructions.

Key Findings
  • After an initial MSLD flap done for various reasons, residual back skin and muscle could be harvested again from the same donor site to salvage radiated implant-based reconstructions in all seven patients.
  • The author argues that these cases challenge the view that the latissimus flap can be used only once. He proposes the MSLD for patients at high risk of reconstructive failure, to keep the latissimus available as a backup.
Caveat

Seven selected cases from one surgeon cannot show how often a second harvest is possible.

Oncoaesthetic Breast Reconstruction After Mastectomy Improves Patient Satisfaction and Aesthetic outcomes.

An integrated onco-aesthetic approach to immediate implant reconstruction was associated with a 35-point gain in BREAST-Q Satisfaction with Breasts. Satisfaction tracked the aesthetic quality achieved more closely than whether contralateral symmetrization was performed.
Overview

This retrospective single-center cohort of 56 patients evaluated immediate implant-based reconstruction within a standardized onco-aesthetic framework: individualized skin-envelope management, implant selection and selective contralateral symmetrization. Outcomes were BREAST-Q Reconstruction scores, Harris photographic aesthetic ratings and complications.

Key Findings
  • BREAST-Q Satisfaction with Breasts improved by 34.9 points. Psychosocial Well-being rose by 20.7, Sexual Well-being by 33.5 and Physical Well-being: Chest by 19.0 (all P < .001).
  • Physician-rated aesthetic outcomes were good to excellent in 62.5% of patients (35/56). Harris aesthetic quality correlated strongly with postoperative Satisfaction with Breasts (ρ = 0.904).
  • Immediate contralateral symmetrization, performed in 24 patients (42.9%), was not independently associated with satisfaction once achieved aesthetic quality was taken into account.
  • Complications occurred in 12 patients (21.4%) and 3 (5.4%) needed implant removal, giving an implant retention rate of 94.6%.
Caveat

There was no comparison group, so the large BREAST-Q gains cannot be credited to the onco-aesthetic framework rather than to reconstruction in general. The cohort is also small and from a single center.

Postoperative complications of breast risk-reduction surgery in very high risk breast cancer patients: A series of 253 cases.

In women at very high breast cancer risk, risk-reducing mastectomy with reconstruction had a 43% overall complication rate, mostly wound healing problems, although only 11% needed reoperation and implant loss occurred in 3.5%.
Overview

This retrospective single-center series of 253 patients covers risk-reducing mastectomies performed at the Toulouse-Oncopole University Cancer Institute between 2015 and 2022, reviewing surgical practice and postoperative complications. Patients had a mean age of 43 years; 48.6% carried BRCA1 and 38.3% BRCA2 mutations.

Key Findings
  • Most reconstructions were prosthetic (67.6%); 17% had free-flap reconstruction and 7% had latissimus dorsi flap reconstruction.
  • At least one postoperative complication occurred in 43% of patients. Most were wound healing disorders (34.9%).
  • Most complications were minor: 32% of patients had a complication that needed no further intervention, while 11.1% required reoperation.
  • Reconstruction failed in 3.5% of implant reconstructions and 5.9% of free flaps.
Caveat

This is a single-center retrospective series with no comparison group. Reconstruction type was not randomized, and the differences the authors note between prosthetic and autologous reconstruction may reflect patient selection as much as technique.

Botulinum Toxin Type A for Postoperative Scar Prevention: A Systematic Review and Meta-analysis.

Suggests that prophylactic botulinum toxin A reduces objective postoperative scar width with moderate certainty, while clinician-rated gains are less certain and higher doses within 4–10 U/cm added no further benefit.
Overview

A systematic review and meta-analysis of 17 comparative trials (456 participants; 656 treatment sites) pooled standardized mean differences for perioperative or postoperative BoNT-A versus control and examined effect modification by injection timing, dose density, and anatomic site.

Key Findings
  • BoNT-A reduced objective scar width (SMD −0.924; 95% CI −1.119 to −0.728; moderate certainty) and improved clinician composite scores (SMD −0.864; low certainty).
  • Pooled clinician-composite analyses showed a larger effect with delayed injection (SMD −1.240) than with immediate injection (SMD −0.559), although direct within-site timing studies conflict.
  • Timing and anatomic site jointly explained 81% of heterogeneity, with the largest effects on the chest and the smallest at fine facial sites.
  • Cross-study dose escalation from 4 to 10 U/cm was not associated with additional benefit, and patient-reported outcomes remained uncertain.
Caveat

The timing and dose comparisons are made across studies rather than randomized within them, and most clinician-rated outcomes carried low or very low certainty, so the optimal injection protocol remains unresolved.

Elastic Double Arch Model-Guided Alar Cartilage Reinforcement With Ligamentous Reconstruction in East Asian Rhinoplasty: A Multicenter Prospective Observational Study.

Suggests that reinforcing the alar arch with thin costal cartilage grafts and reconstructing the tip ligaments can improve aesthetic and functional scores in East Asian primary and revision rhinoplasty while keeping or restoring tip mobility; FACE-Q scores roughly doubled by 36 months.
Overview

This multicenter prospective observational study of 198 patients (213 enrolled; 72 primary and 126 revision) assessed East Asian rhinoplasty using thin cortical costal cartilage grafts to reinforce the alar arch, combined with nasal tip ligament reconstruction, following an Elastic Double Arch Model. Outcomes were VAS-cosmetic, FACE-Q Rhinoplasty, VAS-functional, NOSE, measured nasal tip mobility, and complications, with follow-up up to 36 months.

Key Findings
  • In primary cases with 36-month data, FACE-Q Rhinoplasty scores rose from 42.5 to 84.2 and VAS-cosmetic from 5.02 to 8.40.
  • Revision cases improved by a similar amount: FACE-Q went from 40.2 to 81.5 and VAS-cosmetic from 4.87 to 8.20.
  • Measured nasal tip mobility was preserved in primary cases and markedly restored in revision cases. The authors present this as a response to the tip stiffness associated with conventional structural grafting.
  • Functional scores (VAS-functional and NOSE) improved in both groups. Complications were described as uncommon.
Caveat

There is no control group, such as conventional structural rhinoplasty. The 36-month results come only from patients who had data at that point, so long-term outcomes may reflect a selected subgroup.

Correction of Crooked Nose in Preservation Rhinoplasty with Asymmetric Let-Down Osteotomy.

Suggests that asymmetric let-down osteotomy in preservation rhinoplasty corrects about 90% of severe nasal axis deviation at 12 months without significant recurrence, and does so better than spreader-based structural correction.
Overview

This prospective randomized blinded trial of 64 patients with severe nasal axis deviation compared asymmetric let-down osteotomy (asymmetric bone impaction) in preservation rhinoplasty with conventional structural rhinoplasty using spreader flaps and grafts (32 per arm). Axis correction was measured on pre- and postoperative photographs over 12 months.

Key Findings
  • Asymmetric let-down osteotomy corrected 90 ± 5.67% of the axis deviation at 12 months.
  • Correction held, with no significant recurrence between month 1 and month 12 (p > 0.05).
  • The let-down group had significantly better axis correction than the spreader flap and graft group (p < 0.01).
Caveat

Outcomes rely on photographic measurement of the nasal axis, and 12 months may be too short to detect late redeviation.

Minimally Invasive Breast Augmentation: A Comparative Analysis of Satisfaction, Recovery, and Sensory Outcomes.

Suggests that Mia minimally invasive breast augmentation gives overall satisfaction similar to hybrid implant-plus-fat augmentation, with 74% less reported pain and 61% faster recovery over 6 months.
Overview

This prospective cohort study of 60 women compared Mia minimally invasive breast augmentation with hybrid augmentation (implant plus autologous fat grafting). BREAST-Q outcomes, pain, nipple sensitivity, and recovery were measured before surgery and at 1 week, 1 month, and 6 months.

Key Findings
  • Both techniques produced significant improvements in BREAST-Q breast satisfaction, psychosocial well-being, and overall well-being, and overall satisfaction was similar between cohorts.
  • Mia patients reported 74% less pain and a 61% faster recovery than the hybrid cohort.
  • Patient-reported nipple sensitivity was 41% better after Mia than after hybrid augmentation.
Caveat

Patients were not randomized, and the hybrid arm includes liposuction to harvest fat, which on its own adds pain and downtime. The recovery advantage may therefore reflect less total surgery rather than the augmentation technique itself, and follow-up ends at 6 months.

Comparative Efficacy of 595-nm Pulsed Dye Laser versus CO2 Fractional Laser in the Treatment of Scars Following Cleft Lip Repair.

Suggests that 595-nm pulsed dye laser and CO2 fractional laser improve scars after cleft lip repair by similar amounts, with pulsed dye laser better at reducing redness.
Overview

This randomized trial of 34 patients with scars after cleft lip repair compared 595-nm pulsed dye laser (six sessions at 2-week intervals, n = 17) with CO2 fractional laser (two sessions at 3-month intervals, n = 17). Scars were assessed with the Vancouver Scar Scale one year after surgery.

Key Findings
  • Both lasers produced significant VSS improvement from baseline at one year (p < 0.05).
  • Differences between the two lasers were not significant for most VSS components, including pigmentation, pliability, and height.
  • The pulsed dye laser group showed greater reduction in vascularity, the only parameter where one laser clearly outperformed the other.
Caveat

There was no untreated control arm, so improvement from baseline cannot be separated from natural scar maturation in the first year after surgery. With 17 patients per arm, the trial also has little power to detect differences between the two lasers.

Nanofat in Plastic Surgery: A Systematic Review of Clinical Outcomes, Safety, and Emerging Applications.

Suggests that nanofat improves scar scores and is generally well tolerated, with only mild side effects such as erythema and edema reported across 18 studies, although the evidence base is small and heterogeneous.
Overview

This systematic review of 18 studies (768 patients) followed PRISMA and searched six databases through December 2024 for clinical outcomes and safety of nanofat in aesthetic and reconstructive use, including scars, skin quality, and hair.

Key Findings
  • All eight studies (188 patients) that used the Vancouver Scar Scale or POSAS reported significant scar improvement.
  • In the nine studies (512 patients) that measured satisfaction, most patients reported above-average satisfaction.
  • Twelve studies reported no significant complications such as granulomas or cysts. Eight reported mild side effects, including erythema, hyperpigmentation, and edema.
  • Newer uses rest on very small samples: collagen synthesis and TGF-β1 expression (n = 68), skin histology (n = 24), and hair density and thickness (n = 9).
Caveat

Nanofat preparation methods differ between studies, and the efficacy conclusions may depend on how the nanofat was prepared.

Incidence and Characteristics of Delayed Inflammatory Reactions Secondary to Hyaluronic Acid Filler Injections: A Systematic Review With Meta-Analysis.

Suggests that delayed inflammatory reactions after hyaluronic acid filler are rare, occurring in about 1 in 2000 patients per year of follow-up, with rates that appear to differ by crosslinking technology.
Overview

This systematic review and meta-analysis of 242 studies, with case data from 71 additional reports, used random-effects models to pool the incidence of delayed inflammatory reactions after facial hyaluronic acid filler. Subgroup analysis compared crosslinking technologies.

Key Findings
  • Pooled incidence was 0.0005 events per patient-year (95% CI 0.0002–0.0013), about one event per 2000 patients followed for one year.
  • Rates per patient-year were highest for SHAPE (0.0044) and Vycross (0.0022), compared with 0.0007 for NASHA and 0.0006 for HICE. No incident cases were reported with CPM-based fillers.
  • Median onset was 3 months (range 2 weeks to 12 years), and median time to resolution was 2.9 months (range 1 day to 6 years).
  • Reactions mostly presented as nodules, redness, swelling, and induration, and were usually treated with hyaluronidase, corticosteroids, and antibiotics.
Caveat

Comparisons between technologies are indirect and have wide, overlapping confidence intervals (for example, SHAPE 0.0006–0.0314).

Long-Term Biostimulatory Efficacy of Polycaprolactone Facial Fillers: A Two-Year Quantitative Assessment of Neocollagenesis Using Second-Harmonic Generation Microscopy.

In a rabbit model, polycaprolactone filler (Ellansé-S) increased collagen density by 79% at 12 months before a decline, and the new collagen was structurally similar to native tissue over 2 years.
Overview

This 2-year experimental study in 30 rabbits measured new collagen formation after subcutaneous injection of polycaprolactone microsphere filler (Ellansé-S), compared with tissue that received no implant. Collagen density, alignment, and structure were quantified with second-harmonic generation microscopy and automated image analysis (CT-FIRE and CurveAlign).

Key Findings
  • Collagen fiber density was 79.2% higher at 12 months than in tissue without implant, then began to decline.
  • New collagen formation was detectable throughout the 24-month period, and improving fiber alignment indicated maturation of the collagen network.
  • The new collagen showed no significant difference in structure or organization from native tissue.
Caveat

Rabbit subcutaneous tissue differs from human facial dermis and fat, so the size and timing of collagen induction may not carry over to patients. The authors say the results match clinical observations, but the study contains no human data.

Construct Validity of the GENDER-Q Face and Neck Scales in 4890 Transgender and Gender Diverse Adults.

Suggests the 11 GENDER-Q face and neck scales validly measure facial appearance satisfaction in transgender and gender diverse adults, with 78% to 100% of prespecified hypotheses confirmed per scale.
Overview

An international cross-sectional survey of 4890 transgender and gender diverse adults (2022–2024) tested predefined hypotheses on group differences and inter-scale correlations for the 11 GENDER-Q face and neck scales. Construct validity was judged against the COSMIN threshold of at least 75% of hypotheses confirmed.

Key Findings
  • Across the 11 scales, 78% to 100% of hypotheses met COSMIN criteria, clearing the 75% threshold for hypothesis-based construct validity in every scale.
  • Participants who had undergone gender-affirming facial procedures reported significantly higher appearance satisfaction than those who still wanted surgery or required revision surgery.
  • Nearly a quarter of respondents identified as nonbinary (24%), alongside women (37%), men (33%), and other genders (6%); all completed the Face Overall scale plus additional scales as relevant.
Caveat

Validity was established cross-sectionally by comparing different groups of respondents, so the scales' ability to detect change within the same patient before and after facial surgery is not tested here.

Dynamic Yet Stable Nasal Tip: Dual-pillar Medial Crural Reinforcement Technique Preserving Natural Alignment and Infratip Break in Asian Rhinoplasty.

Suggests that paired thin cartilage grafts sutured along each medial crus can raise tip projection (Goode ratio 0.51 to 0.58) while preserving physiological tip mobility in 90% of Asian rhinoplasty patients, without rigid septal fixation.
Overview

A retrospective case series of 42 Asian rhinoplasty patients (2023–2025) describes the dual-pillar technique, in which thin cartilage grafts (0.8–2.0 mm) are shaped and secured along each medial crus with interrupted 5-0 polydioxanone sutures without septal coupling. Indications were Goode ratio below 0.55, weak or asymmetric medial crura, and a preference for a mobile tip.

Key Findings
  • Mean Goode ratio increased from 0.51 to 0.58 (P < 0.001), moving tip projection above the 0.55 indication threshold.
  • Mean infratip break angle narrowed from 139 to 118 degrees (P < 0.001), indicating a more defined infratip break.
  • Grade 3 physiological tip mobility was retained in 38 of 42 patients (90%) on a pragmatic 4-point clinical scale; the remaining 4 showed grade 2 mobility.
  • Mean patient satisfaction was 8.7 of 10 on a visual analog scale, and no complications requiring revision occurred.
Caveat

The series has no comparison group such as septal extension grafting, and with patients treated between 2023 and 2025, durability of projection without rigid septal support remains unproven.

Upper- versus lower-extremity synovial sarcoma: distinct surgical pathways and postoperative morbidity in a 24-year cohort.

Suggests upper-extremity synovial sarcomas more often have positive margins at first resection (61% vs 14%) yet far fewer postoperative complications (13% vs 53%) than lower-extremity tumors, with definitive R0 reached in both.
Overview

A retrospective single-center cohort of 59 patients with extremity synovial sarcoma (2000–2023) compared 23 upper- with 36 lower-extremity tumors for R1 margin at index resection and Clavien-Dindo complications within 8 weeks. Metastasis-free and overall survival were exploratory endpoints.

Key Findings
  • R1 at the index resection occurred in 61% of upper- vs 14% of lower-extremity tumors (OR 9.64, 95% CI 2.73–34.1); neoadjuvant therapy was also more frequent in the upper extremity (39% vs 8%).
  • Definitive R0 was ultimately achieved in every patient, despite the higher initial R1 rate in upper-extremity tumors.
  • Any postoperative complication was more frequent after lower-extremity surgery (53% vs 13%; OR 0.13 for upper vs lower), as were major complications (39% vs 9%).
  • Seven of nine distant metastases arose in lower-extremity tumors, several beyond six years; 10-year metastasis-free survival was 90% vs 56% favoring the upper extremity, without statistical significance (P = 0.095).
Caveat

With 59 patients treated over 24 years at one center, the study is underpowered for survival endpoints and cannot separate the effect of location from differences in tumor size, depth, or treatment era.

[Surgical treatment of primary malignant bone tumors : Local therapeutic considerations with respect to extent of resection and reconstruction in a multimodal treatment concept].

Reiterates that complete R0 resection within chemotherapy-led multimodal treatment is the local goal for curable primary bone sarcomas, with resection quality shaping local recurrence, prognosis, and reconstruction choice.
Overview

A German-language review summarizes local surgical strategy for primary malignant bone tumors within multimodal treatment, covering extent of resection, reconstruction options, and integration with chemotherapy and radiotherapy.

Key Findings
  • Conventional chemotherapy leads first-line treatment, and complete R0 resection is the local procedure of choice in curative-intent care.
  • In Ewing sarcoma, additional local radiotherapy must be accounted for in both surgical planning and the choice of reconstruction.
  • The quality of tumor removal directly influences local recurrence rate, overall prognosis, and reconstruction type; palliative cases require individually adapted treatment.
  • Because of disease rarity and the degree of specialization required, treatment is restricted to specialized centers.
Caveat

As a review of treatment principles, it offers general guidance on resection and reconstruction for primary bone sarcomas. The choice of reconstruction for a given tumor site and patient still has to be made case by case.

An individualized reconstructive algorithm for large facial defects after tumor resection in elderly patients: A retrospective case series.

Suggests that matching reconstruction (skin graft, regional flap, or free flap) to defect characteristics and operative tolerance achieved complete closure with survival of all grafts and flaps in 28 elderly patients with large facial defects.
Overview

A retrospective case series of 28 patients aged 65 or older with large post-oncologic facial defects (5 × 6 cm to 12 × 16 cm) describes an individualized algorithm assigning full-thickness skin grafts, regional or pedicled flaps, or free flaps by defect complexity and physiologic reserve. Outcomes were reassessed by two non-operating plastic surgeons using de-identified records, photographs, and a predefined functional checklist.

Key Findings
  • Nearly half were managed with full-thickness skin grafts (13 of 28), with regional or pedicled flaps in 9 and free or bulky myocutaneous flaps in 6.
  • Complete wound closure and survival of all 28 grafts and flaps were achieved.
  • Five complications occurred within 30 days, all Clavien-Dindo grade I or II; no grade III–V events were recorded.
  • No reconstruction failure was documented in the 27 curative-intent cases, and the single palliative case achieved stable coverage and local symptom control.
Caveat

Follow-up was short and uneven across groups (median 5 months for skin grafts vs 16 months for free flaps), and without a comparison group the algorithm's allocation criteria cannot be tested against alternatives.

Ultrasound-Guided Histotripsy for Non-Invasive Treatment of Ex Vivo Soft Tissue Tumors: Preclinical Feasibility Study.

Demonstrates that ultrasound-guided histotripsy produced an identifiable ablation effect across all tested soft tissue tumor subtypes in 45 ex vivo specimens, although the histologic effect varied with tumor tissue structure.
Overview

A preclinical ex vivo study of 45 surgically excised human soft tissue tumor specimens applied histotripsy with a custom 1 MHz, 8-element ultrasound transducer under ultrasound imaging guidance. Specimens ranged from benign adipocytic, myxoid, and nerve sheath tumors to aggressive fibrous and high-grade sarcomas.

Key Findings
  • Histotripsy created an identifiable treatment effect across all tumor subtypes, including adipocytic tumors, benign myxoid and nerve sheath tumors, aggressive fibrous sarcomas, and high-grade sarcomas.
  • Immediately after treatment, B-mode and shear-wave elastography ultrasound effectively evaluated the treated region.
  • Histologic treatment effect varied with tissue structure heterogeneity among subtypes, pointing to a need for subtype-specific parameter optimization.
Caveat

Excised specimens lack perfusion, overlying skin, and adjacent critical structures, so the completeness, safety, and oncologic benefit of ablation in living patients remain unknown.

Diagnostic Accuracy of AI in Prediction and Assessment of Compromised Free Flaps: Systematic Review and Meta-Analysis.

Suggests that AI tools, particularly image-based models, detect free flap vascular compromise with high pooled accuracy (AUC 0.98 for image-based models), although the certainty of evidence is low.
Overview

A systematic review and diagnostic accuracy meta-analysis of 18 studies (17 pooled quantitatively) estimated sensitivity, specificity, AUC, and diagnostic odds ratio of AI models for postoperative free flap monitoring and compromise prediction using a hierarchical bivariate random-effects model, with subgroup analyses by modality.

Key Findings
  • Across all models, pooled sensitivity was 0.83 and specificity 0.87, with an AUC of 0.92; prediction intervals were very wide (specificity PI 0.03–1.00).
  • Image-based models outperformed non-image models, with sensitivity 0.92, specificity 0.95, and AUC 0.98 versus 0.69, 0.72, and 0.79.
  • For vascular compromise detection specifically, pooled sensitivity was 0.92 and specificity 0.91.
  • Heterogeneity was substantial, QUADAS-2 flagged methodological concerns in several studies, and GRADE certainty was low.
Caveat

Few models were externally validated and prediction intervals spanned nearly the full range, so pooled accuracy may not transfer to a different unit's flap population or imaging setup.

Detecting Manipulated Online Rhinoplasty Images Using an Artificial Intelligence Facial Authenticity Localization (FAL) Model.

Suggests that roughly one in five (19.5%) public postoperative rhinoplasty photos on RealSelf show signs of digital manipulation of the nasal region, based on an AI authenticity detector.
Overview

A cross-sectional analysis of 600 consecutive postoperative rhinoplasty photographs from RealSelf.com applied the Facial Authenticity Localization (FAL) AI model, counting nasal-region heatmap activations as positives. Specificity was estimated on 200 presumed-unedited clinical photographs and sensitivity on 50 intentionally warped clinical photographs.

Key Findings
  • FAL flagged 19.5% of public images (117/600) as probable nasal manipulations (95% CI 16.3–22.7%).
  • The false-positive rate on presumed-unedited clinical photographs was 1.5% (3/200) (95% CI 0.51–4.32%).
  • Sensitivity for Facetune-generated geometric warps was 100% (50/50) (95% CI 93.0–100%).
Caveat

Validation relied on the authors' own clinical photos and deliberate Facetune warps, so accuracy on real platform images with varied compression, lighting, and editing tools is unconfirmed; a positive is a flag of suspected editing, not proof of manipulation.

From pixels to prediction: CT morphometrics and artificial intelligence in complex ventral hernia repair.

Suggests CT-derived morphometrics such as volumetrics, loss-of-domain measures, and sarcopenia are associated with fascial closure and complications in complex ventral hernia repair, while AI prediction tools remain insufficiently validated for routine use.
Overview

A structured literature review of PubMed/MEDLINE, Scopus, and Web of Science, with quality appraisal and narrative synthesis, evaluated CT-derived morphometrics, body composition, radiomics, and AI applications in complex ventral and incisional hernia repair.

Key Findings
  • CT volumetrics, standardized loss-of-domain measures, muscle morphology, sarcopenia, myosteatosis, and adipose distribution were associated with fascial closure and need for component separation, as well as surgical-site occurrences.
  • Emerging AI tools, including automated segmentation, radiomics, and machine-learning risk models, showed promising performance for quantitative image analysis and individualized risk prediction.
  • The evidence base is predominantly retrospective and single-centre, with heterogeneous imaging definitions, small datasets, and limited external validation precluding widespread clinical implementation.
Caveat

Findings were synthesized narratively without pooled estimates, which leaves the relative strength of individual morphometric predictors open.

Automated Brief Hospital Course Summarization in Cardiac Surgery Using a Lightweight Large Language Model-Based Framework: Development and Evaluation Study on the Medical Information Mart for Intensive Care-IV.

A locally run 8-billion-parameter language model, used without fine-tuning, produced cardiac surgery hospital course summaries that 15 cardiac surgeons rated above the acceptability threshold (mean ≥3.0 of 5) in every quality domain.
Overview

This development and evaluation study of 4538 CABG cases from MIMIC-IV tested LiteMedDoc, a locally deployable pipeline built on Llama 3.1 (8B) without fine-tuning, for generating brief hospital course summaries. Outputs on a 403-case held-out test set were compared with reference summaries using 8 NLP metrics and rated by 15 cardiac surgeons.

Key Findings
  • Without any model training, LiteMedDoc nearly matched a fine-tuned model and exceeded a 70-billion-parameter model on all automated metrics spanning lexical overlap, semantic similarity, and clinical relevance.
  • In a within-database cross-domain test on lobectomy cases, the framework after prompt adaptation outperformed both the base model and the CABG-fine-tuned model.
  • Surgeons rated summaries above the prespecified acceptability threshold for completeness, correctness, readability, conciseness, and global quality, specifically noting their structure and conciseness.
  • The pipeline combines chronological structuring of multisource inputs, retrieval of similar prior case summaries, and offline prompt optimization, with all processing performed locally.
Caveat

The acceptability bar was a mean Likert score of 3.0 on a sample of summaries, and a mean rating can mask individual drafts with clinically important errors or omissions.

Artificial Intelligence in Plastic and Reconstructive Surgery: A Bibliometric Study of the 50 Most-cited Articles.

Suggests that influential AI research in plastic surgery has concentrated on craniofacial surgery (32 of the 50 most-cited articles) and image-based assessment, with other subspecialties less represented.
Overview

This bibliometric analysis of the 50 most-cited articles on artificial intelligence in plastic and reconstructive surgery drew on a Web of Science Core Collection search (November 18, 2025), recording authorship, country, journal, funding, and citation counts. Articles were classified by AI application domain and plastic surgery subspecialty.

Key Findings
  • The articles were published between 2001 and 2024, with citation counts ranging from 45 to 124.
  • Most articles originated from the United States (n = 18; 1166 citations), and plastic surgeons were the most frequent authors (n = 17; 1332 citations).
  • Imaging assessment was the most common AI application (n = 21; 1564 citations).
  • Craniofacial surgery was the predominant subspecialty (n = 32; 2364 citations), with uneven adoption across other areas of plastic surgery.
Caveat

Citation counts from a single database reward older papers and measure accumulated attention rather than methodological quality or clinical impact, so recent and potentially more relevant work is underrepresented.

Application of electrospun piezoelectric nanofibers in wound healing.

This review suggests that electrospun piezoelectric nanofiber dressings, which convert small mechanical deformations into local electrical signals, could help accelerate repair of hard-to-heal wounds such as diabetic ulcers.
Overview

This review summarizes the functional properties of electrospun piezoelectric nanofiber dressings and the biological mechanisms by which electrical stimulation promotes wound healing, with a focus on hard-to-heal wounds such as diabetic ulcers.

Key Findings
  • The fibrous architecture of electrospun dressings is described as conforming to irregular wound contours, supporting rapid hemostasis, and acting as a barrier against microbial invasion.
  • The piezoelectric effect converts micromechanical deformation into localized electrical signals in real time, which the authors link to modulation of cell behavior and accelerated tissue repair.
  • The review compiles recent mechanistic studies of electrical stimulation in wound healing as a theoretical basis for the design and optimization of next-generation dressings.
Caveat

The review is framed as a theoretical foundation for future dressing design and clinical translation, and its evidence centers on mechanisms of electrical stimulation. Whether piezoelectric dressings speed healing of diabetic ulcers or other hard-to-heal wounds in patients remains to be shown.

A novel CAVIN1/GAS5 axis suppresses skin fibrosis through mitochondrial fission-mediated attenuation of the TGF-β/Smad pathway.

Suggests that loss of the protein CAVIN1 contributes to keloid fibrosis, and that restoring it, including with the repurposed drug vorinostat, reduced skin fibrosis in mouse models.
Overview

This multiomics and mechanistic laboratory study integrated transcriptomic and proteomic profiling of patient-derived keloid and normal skin, then tested candidate regulators in primary keloid fibroblasts using gain- and loss-of-function, RIP-seq, and RNA stability assays, followed by two bleomycin-induced skin fibrosis mouse models.

Key Findings
  • Multiomics profiling showed CAVIN1 consistently downregulated in keloids; its overexpression in keloid fibroblasts suppressed migration, invasion, collagen contraction, and extracellular matrix protein expression.
  • CAVIN1 bound and stabilized the lncRNA GAS5, which inhibited Drp1/Fis1-mediated mitochondrial fission and ROS production, attenuating canonical TGF-β/Smad2/3 signaling.
  • GAS5 silencing abrogated the antifibrotic effects of CAVIN1, supporting GAS5 as the required downstream mediator in fibroblasts.
  • Database screening identified vorinostat as a CAVIN1-upregulating compound; both AAV-mediated CAVIN1 overexpression and vorinostat ameliorated fibrosis in the mouse models.
Caveat

Mice do not form keloids, so the bleomycin models test general skin fibrosis rather than keloid disease itself, and no human treatment data are reported.

Therapeutic modulation of the vitreoretinal fibrosis microenvironment in female mice using engineered macrophage-derived extracellular vesicles.

Suggests that engineered macrophage-derived vesicles carrying anti-TGFβ1 antibodies reduced vitreoretinal fibrosis in female mice by combining growth-factor blockade with macrophage reprogramming.
Overview

This preclinical study in female mouse models of proliferative vitreoretinopathy (PVR) tested intravitreal M1 macrophage-derived extracellular vesicles conjugated to anti-TGFβ1 antibodies via MMP-cleavable linkers (ACE), plus a variant adding anti-PDGFR antibodies (ACEPlus) evaluated in advanced disease and a patient-derived membrane xenograft model.

Key Findings
  • Data mining of patient and mouse PVR tissue showed elevated TGFβ1 and M2 macrophage enrichment in the fibrotic microenvironment, which guided the vesicle design.
  • After intravitreal injection, ACE selectively accumulated in lesions, where released antibodies neutralized TGFβ1 and the M1 vesicles inhibited M2 polarization, diminishing fibrosis.
  • Adding anti-PDGFR antibodies (ACEPlus) prevented progression of retinal detachment in advanced-stage PVR, with efficacy confirmed in a patient-derived PVR membrane xenograft model.
Caveat

All in vivo work used female mice and a xenograft model, and the proposed role as an alternative to surgery is untested in humans; relevance to cutaneous fibrosis is by analogy only.

Mechanistic Insights and Therapeutic Potential of Plant-Derived Exosome-Like Nanovesicles in Skin Tissue Regeneration.

Summarizes evidence that plant-derived exosome-like nanovesicles may influence multiple phases of skin wound healing, from inflammation and angiogenesis to nerve and skin appendage regeneration.
Overview

This review synthesizes proposed mechanisms by which plant-derived exosome-like nanovesicles (PENs) act across the phases of skin wound healing and summarizes current isolation and characterization technologies.

Key Findings
  • Compared with mammalian and microbial extracellular vesicles, PENs are described as offering scalable production, high biosafety, and low immunogenicity.
  • In the inflammatory phase, PENs are reported to shift macrophage polarization, suppress inflammasome activation, and reduce oxidative stress.
  • PENs are linked to enhanced angiogenesis via proangiogenic marker upregulation and ferroptosis inhibition, and to peripheral nerve repair through PI3K/ERK activation.
  • Beyond wound closure, PENs are reported to support regeneration of hair follicles, sebaceous glands, and sweat glands, partly through Wnt/β-catenin signaling.
Caveat

This review assembles a mechanistic framework for PENs as nanomedicines still under development. Whether the described effects on inflammation, angiogenesis and appendage regeneration translate into better wound healing in patients remains open.

Substrate curvature and stiffness equivalence in governing cell mechanosensing.

Demonstrates that the tilt of focal adhesions relative to the substrate decreases as substrate stiffness rises, and that curving a rigid surface can reproduce the cellular response to a given stiffness.
Overview

This experimental and computational mechanobiology study used reverse cell imprinting, atomic force microscopy, and a two-dimensional clutch model to examine focal adhesion (FA) tilting, then engineered rigid substrates with defined curvatures to impose tilt independently of stiffness.

Key Findings
  • Imaging and atomic force microscopy showed a strong inverse correlation between FA tilting angle and substrate stiffness.
  • The clutch model indicated that tilting emerges from force distribution across the FA-substrate interface and contributes to cell mechanosensing.
  • Rigid substrates with defined curvatures imposed specific tilting angles and modulated the cellular mechanostate, allowing construction of a map linking curvature values to equivalent stiffness levels.
Caveat

Findings come from cells on engineered substrates in vitro, and whether the curvature-stiffness equivalence translates to scaffold or implant design in tissue remains open.

Expanding Criteria for Totally Extraperitoneal Robotic DIEP Flap Harvest: A Case Report and Review of the Literature.

Ting J et al.·Microsurgery Breast

This case report of one patient, with an accompanying literature review, describes a totally extraperitoneal (TEP) robotic DIEP flap harvest in a patient with a long (91.6 mm) intramuscular perforator, a course that conventional robotic selection criteria limited to short perforators would exclude.

Nasal Septum Reconstruction With Medial Femoral Condyle Free Flap: A Case Report and Literature Review.

Uyar İ, Aksam E·Microsurgery Reconstruction & Microsurgery

This case report of a single patient, paired with a literature review, describes reconstruction of an anterior nasal septal defect after prior tumor surgery using a vascularized medial femoral condyle (MFC) free flap. The flap was chosen for its cortical bone with periosteal architecture and its limited donor-site morbidity.

Acute Herpes Zoster-Like Eruption in a Free Flap after Reconstruction of Post-Burn Hand Contracture: A Case Report.

Lee JK, Kim JT·Hand Surg Rehabil Reconstruction & Microsurgery

This case report of a single patient describes a herpes zoster-like vesicular eruption involving a lateral thoracic perforator free flap after release of a severe post-burn contracture of the hand and wrist. The report traces the timing of the lesions relative to flap monitoring and partial flap loss.

High-Grade Chondrosarcoma Involving the Xiphoid Process and Lower Sternum-The Continuing Role of Extended Open Chest Wall Surgery in the Era of Minimally Invasive Thoracic Surgery: A Case Report.

Rallis T et al.·Curr Oncol Sarcoma & Oncology

This case report of a single patient describes a 62-year-old man with severe obesity and a heavy smoking history who had a grade III chondrosarcoma of the xiphoid and lower sternum. The tumor was treated with extended open resection and prosthetic chest wall reconstruction.

Closing Notes

Much of this issue concerns substitution rather than invention: regional anaesthesia for head and neck free flaps, temporal instead of cervical recipient vessels, the procedure room instead of the main theatre, a minimally invasive augmentation against a hybrid one. When these comparisons find a difference, it lies in operative time, pain, recovery or cost, while the core surgical result looks similar. That is a fair reason to change practice if the groups were alike. Apart from the two randomised trials in the aesthetic section, the week's comparative studies are observational, and their arms reflect who was offered each option. Several technique series are also one surgeon's work. That shows an operation can succeed but not yet how well it travels.

A second pattern is quieter. Longer daily orthosis wear was not associated with more pain relief, and a higher toxin dose did not narrow scars further. Thousands of pooled DIEP flaps yielded no patient-level factor that reliably predicted venous congestion. After immediate breast reconstruction, shoulder motion was more often limited while reported disability was not worse. Each result marks a limit, either to what extra effort buys or to what a single measure can tell the surgeon. In a week built largely on parity and feasibility, these may be the findings most readily carried into the clinic.
