RESUMEN
BACKGROUND: Large and deep perineal defects following abdominal perineal resection (APR) are a challenge for reconstructive surgeons. Even if generally performed for oncological reasons, APR can be indicated as well in extended infection-related debridement for Hidradenitis suppurativa, Fournier's gangrene, or Crohn's disease. We aimed to compare the outcomes of two groups of patients with different indications for APR (infectious vs. oncological) after pedicled anterolateral thigh (ALT) flap coverage RESULTS: Forty-four consecutive pedicled ALT flap used for coverage after APR in 40 patients were analyzed. 26 patients (65%) underwent APR for oncological reasons and 14 patients (35%) for infectious reasons. The overall postoperative complications rate was significantly higher for infectious cases (76.5% vs. 40.7%, p = 0.0304). Major complications occurred in 52.9% of infectious cases versus 11.1% of oncological cases (p = 0.0045). Obesity and infectious etiology were independent risk factors for overall and major complications, respectively. CONCLUSION: Patients undergoing APR for acute or chronic infections had significantly more overall and major complications than patients having oncological APR. Modified care might be considered, especially in obese patients, in terms of surgical debridement, antibiotic treatment modalities, and postoperative management.

BACKGROUND: Total hip arthroplasty is a widely performed surgical procedure, which enables patients to regain mobility, alleviates pain, and improves overall quality of life. Periarticular multimodal drug infiltration (PAI) is increasingly being used as an effective postoperative pain management, decreasing the systemic consumption of opioids. Extensive postoperative skin necrosis without a deep joint infection as a complication of total hip arthroplasty with PAI has not yet been described. CASE PRESENTATION: A 71-year-old patient who underwent total hip arthroplasty of the right hip for primary osteoarthritis through the Direct Anterior Approach presented postoperatively a large area of necrotic skin at the incision. Joint infection was excluded. An extensive debridement was performed and the tissue defect was reconstructed by a pedicled anterolateral thigh flap. The skin maintained a satisfactory appearance at 1 year postoperatively, and the hip was pain-free with restored ranges of motion. The patient was able to walk with no support and without limitation. CONCLUSION: We address the possible risk factors, discuss the use of epinephrine in PAI and explore possible treatment options for such a complication.

Wound healing issues are not rare after total knee arthroplasty. While most patients heal with local wound care, a minority is susceptible to develop serious complications such as peri-prosthetic joint infection. If direct closure is not feasible, we recommend a multidisciplinary approach based on the ortho-plastic model to determine the optimal wound closure strategy. Negative pressure wound therapy can be used while waiting for definitive coverage to optimise wound environment. Medial gastrocnemius flap is considered as the gold standard procedure for peri-prosthetic substance loss around the knee.
Les problèmes de cicatrisation ne sont pas rares après l'implantation d'une prothèse totale de genou. La plupart des patients guérissent avec des soins locaux mais une minorité d'entre eux peut développer des complications redoutables allant jusqu'à l'infection périprothétique. Hormis les situations pour lesquelles une fermeture directe de la cicatrice chirurgicale peut être réalisée, nous recommandons une approche multidisciplinaire basée sur le modèle de l'ortho-plastique afin de déterminer la stratégie de reconstruction la plus adaptée. La thérapie par pression négative peut être utilisée pour conditionner la plaie en vue d'un geste de couverture définitive. Le lambeau gastrocnémien médial est considéré comme la procédure de référence pour les pertes de substance périprothétique du genou.

Breast hypertrophy (macromastia) can cause various symptoms correlated with excessive breast volume and is usually associated with breast ptosis. Symptomatic macromastia can constitute a heavy burden on patient's global health. While conservative therapy does not allow for long term relief, breast reduction mammaplasty is an effective and safe treatment. Multiple techniques have been described, but all rely on common principles. Measures can be taken to lower surgical complications rates and implemented by primary care physicians in collaboration with the plastic surgery approach.
L'hypertrophie mammaire symptomatique se définit comme un ou plusieurs symptômes en lien avec un volume mammaire augmenté, en général associé à une ptose mammaire. Elle peut avoir un impact majeur sur la santé globale des patientes. Alors que les traitements conservateurs ne permettent pas de soulager les patientes à long terme, la réduction mammaire chirurgicale est un traitement efficace et sûr. De nombreuses techniques ont été décrites, mais reposent sur des principes communs. Certaines mesures permettent une diminution des risques de complications chirurgicales et peuvent être entreprises conjointement à la prise en charge en chirurgie plastique.

BACKGROUND: Over the years, many techniques have been described to correct tear trough deformity (TTD). Fat-repositioning lower blepharoplasty via a transconjunctival approach is increasingly applied due to its satisfactory rejuvenating effect. However, those methods have disadvantages such as a complicated surgical approach, residual scar, and long recovery time. OBJECTIVES: We modified the surgical technique of fat-repositioning transconjunctival lower blepharoplasty with an effective but easy internal fixation method via a supraperiosteal approach. METHODS: From January 2014 to December 2017, 110 patients underwent bilateral modified lower blepharoplasty with fat-repositioning. Preoperatively, the grade of TTD was evaluated according to Barton's grading system. Postoperative results and complications were assessed during the follow-up period. RESULTS: TTD was ameliorated in 97.73% of the cases; the remaining 2.27% cases with no improvement underwent revision and achieved Grade 0 on Barton's grading system thereafter. All patients were satisfied with the final outcome. Few postoperative complications were observed, none of which led to a permanent condition. Three cases of local depression and one case of local bulge were treated with surgical refinements. One case of postoperative hemorrhage was healed by electrocautery. CONCLUSIONS: Our modified method of transconjunctival lower blepharoplasty with fat repositioning is safe and effective to improve TTD without severe orbital skin laxity.

PURPOSE: The aim is to describe a technique with orthograde dissection of the anterior tibial artery (ATA) used as the recipient vessel for the end-to-end (ETE) anastomosis in defect reconstruction around the knee and for proximal/middle third leg defects with free anterolateral thigh (ALT) and gracilis flaps. PATIENTS AND METHODS: Between March 2009 and May 2014, 22 patients undergoing lower extremity reconstruction were evaluated. Of those, 4 patients were included. The locations of injury were 3 defects around the knee and 1 defect at the proximal and middle third of the lower leg (mean defect size 18 x 8.5 cm and a range of 17-20 x 5-10 cm). There were 2 cases after trauma and 2 cases with infection. Two free gracilis and 2 free ALT flaps were performed of equal size to the defects. The mean flap pedicle length was 11 cm (range of 7-16 cm) and the mean length of the mobilized recipient vessels was 10.5 cm (range of 6-14 cm). RESULTS: One flap loss (ALT) occurred, requiring a salvage procedure with a latissimus dorsi flap, whereas wound dehiscence at the donor site and a hematoma below the ALT flap was observed in 2 cases, requiring small revision. After a mean follow-up of 52 months (range of 38-87 months), there was stable soft tissue coverage in all patients. CONCLUSION: By orthograde dissection of the ATA, an adequate vessel length and size may be achieved, improving arc of rotation to successfully cover more distant defects.

A patient presented with a complex penetrating facial wound by high temperature steel. The hot steel penetrated right temple, ethmoid bone, and maxillary sinus, and then exited from his left cheek. He kept his right eye but lost his sight. For functional and esthetic considerations, treatments were provided in a staged procedure. First, the debridement was performed under the endoscope. The dead bone was removed, broken teeth were extracted, and necrotic tissue was cleaned. The exposed wounds were cleaned, and dressing was changed daily until the exudation was widely reduced. Then, a 50-mL expander was placed in the left cheek, and an 80-mL expander was put in the scalp just before the defect in the temple area. Five months later, expander inflation was accomplished. Expanders were taken out and expanded flaps were transposed to cover the defect. At the same time, an anterolateral thigh flap was harvested to repair the inner lining of the cheek and the gingiva. Thereafter, several operations were performed to revise the wound scar and the remaining deformity. Both defects in the temple and left cheek were restored with a satisfactory functional and aesthetic outcome. The temporal area was repaired with haired expanded scalp, whereas the face was repaired with an expanded facial flap with similar texture and color. The oral commissure regained balance and integrity. The defect of the gingiva was repaired. A severe penetrating wound in the cranium and face can be nicely repaired using tissue expander and microvascular reconstruction.

BACKGROUND: Abdominal cutaneous sensitivity loss after abdominoplasty is an undesirable outcome. However, little is known in the literature about sensitivity changes of the neo-umbilicus after abdominoplasty. The aim of this study was to evaluate post-abdominoplasty cutaneous sensitivity of the neo-umbilicus using clinical, quantitative, and reproducible methods. METHODS: Patients who underwent abdominoplasty were included, whereas the control group consisted of healthy volunteers with similar demographic characteristics but who did not undergo abdominoplasty. The umbilicus was divided into five zones, and superficial tactile sensitivity and spatial orientation were assessed subjectively (score 1-4) and objectively (Semmes-Weinstein monofilament examination). RESULTS: Twenty patients (45 ± 12 years) operated on consecutively between April 2012 and May 2016 and 14 healthy volunteers in the control group (39 ± 9 years) could be included. Although there were statistically significant differences (p = 0.0005) in the average cutaneous pressure thresholds between the control group (0.4 g/mm2, range 0.07-2 g/mm2) and the study group (0.4 g/mm2, range 0.07-4 g/mm2), patient satisfaction after a mean follow-up of 33 ± 16 months (range 10-62 months) was acceptable (mean satisfaction score 1.8 ± 0.7). Furthermore, spatial perceptions were precise in all patients and similar to the control group. CONCLUSION: Our long-term results indicate that spontaneous reinnervation of the neo-umbilicus after abdominoplasty together with accurate spatial orientation can occur.

BACKGROUND: Little is known about the influence of the underlying tissue as donor for nipple-areola complex (NAC) reconstruction. Also, there is a complete lack of knowledge about the fate of nipple volume. OBJECTIVES: The goal of this retrospective, single-institution study was to analyze a case series after nipple reconstruction using a multimodal evaluation including 3-dimensional (3D) laser scanner analyses. METHODS: Unilateral mastectomy patients after either expander-based or autologous breast reconstruction using the skate flap were included. NAC caliper measurement of nipple and areola size was performed. 3D laser scanner analysis (Minolta Vivid 900) was used to calculate nipple volume, measurement of nipple, and areolar projection and diameter. Sensitivity was evaluated using the Semmes Weinstein test and patient satisfaction by a visual analog scale (VAS 1-10). RESULTS: A total of 10 patients were included in the expander group and 12 patients were included in the flap group. After a median follow-up period of 32 months in the expander group and 34 months in the flap group, non-contact 3D laser surface scanning revealed a difference in projection of 55 to 60% compared to the contralateral side. The contraction in all 3 dimensions led to a dramatic difference in nipple volume with 12 ± 8% (flap reconstructions) and 12 ± 7% (expander reconstructions). Sensitivity of the areola showed better values after expander-based reconstruction. Despite the significant discrepancy in nipple volume and projection as well as areolar diameter, overall patient satisfaction was acceptable (VAS 4.1 ± 3.5). CONCLUSIONS: Volume assessment revealed a massive asymmetry to the intact nipple but not between expander and flap reconstructions. Although asymmetry of the areola and nipple remains, patient satisfaction is acceptable. LEVEL OF EVIDENCE 4.

Background: Many studies of gluteal augmentation techniques have been published in recent decades, including case reports, retrospective and prospective case series, and multicenter survey reviews. However, to date, there has been no study of the overall complications or satisfaction rates associated with the broad spectrum of techniques. Objectives: The authors performed a comprehensive literature review to determine outcomes and complications of gluteoplasty techniques, including patient satisfaction. Methods: A search on PubMed/Medline was performed for clinical studies involving gluteal augmentation techniques. A priori criteria were used to review the resulting articles. Results: Fifty-two studies, published from 1969 through 2015, were included - representing 7834 treated patients. Five gluteal augmentation techniques were identified from these studies: gluteal augmentation with implants (n = 4781), autologous fat grafting (n = 2609), local flaps (n = 369), hyaluronic acid gel injection (n = 69), and local tissue rearrangement (n = 6). The overall complication rates of the most commonly utilized techniques were: 30.5% for gluteal augmentation with implants, 10.5% for autologous fat grafting, and 22% for local flaps. Patients' satisfaction was reported as consistently high for all the five techniques. Conclusions: Implant-based gluteal augmentation is associated with high patients' satisfaction despite a high complication rate, while autologous fat grafting is associated with the lowest complication rate yet including serious major complications such as fat embolism. Local flaps and local tissue rearrangements are the ideal procedures in case of massive weight loss patients. A paucity of data is available for hyaluronic acid gel injections, which appear to be effective but temporary and expensive.

BACKGROUND: Breast-conserving surgery is the standard of care for early-stage breast cancer but can often result in unsatisfactory cosmetic outcomes. Oncoplastic surgery aims to address these issues by combining local excision with plastic surgery techniques to improve oncologic and esthetic outcomes. By incorporating breast reduction techniques into cancer surgery, wider margins of excision can be achieved, leading to enhanced oncological safety and reduced recurrence rates without causing significant asymmetry. This systematic review and meta-analysis aims to provide an updated understanding of the surgical outcomes associated with oncoplastic reduction mammoplasty. METHODS: A systematic review of the literature was conducted according to PRISMA guidelines. Articles reporting post-operative outcomes following the oncoplastic reduction mammoplasty were included. A proportional meta-analysis of post-operative complications was performed to obtain their proportions and 95% Confidence Intervals (CIs). RESULTS: Eighteen studies met the inclusion criteria, representing a total of 2711 oncoplastic reduction mammoplasty procedures in 2680 patients. The overall complication rate was 20% (95% CI: 15-25%). The positive margin rate following oncoplastic reduction mammoplasty was 11% (95% CI: 6-17%). The re-excision rate was 6% (95% CI: 3-12%). The completion mastectomy rate was 3% (95% CI: 2-6%). CONCLUSIONS: Oncoplastic reduction mammoplasty is a safe and effective alternative to mastectomy and traditional breast-conserving surgery in the treatment of early-stage breast cancers.

Soft tissue defects of the distal third of the leg are challenging and management with simple split thickness skin graft or conservative measures is often difficult. The peroneus brevis muscle flap is well described in the literature to cover such defects. The aim of our study was to review the different applications and potential complications of the peroneus brevis muscle flap. A comprehensive review of all existing evidence on the use of peroneus brevis muscle flaps for coverage of defects in the distal third of the leg in adult populations was performed. Two hundred forty-eight records were identified in the literature search, among which 15 met the PICOS (Patient, Intervention, Comparison, Outcome and Study design) criteria. All selected studies were retrospective. Overall, 222 patients who received peroneus brevis muscle flaps were analyzed. Indications for reconstruction were post-traumatic defects, infected wounds, and chronic wounds. The overall complication rate was 21% (46/222) with the most commonly reported complication being skin graft loss. We observed 2 cases of partial flap loss, 17 cases of skin graft loss, 2 cases of post-operative hematoma, 2 cases of recurrent infection, 12 cases of partial flap necrosis, 3 cases of skin graft necrosis, and 8 cases of delayed wound healing. Overall, 16 patients (7%) required revision surgery. No cases of donor site morbidity were described. The current review shows that the peroneus brevis muscle flap is a versatile and reliable option for the coverage of small to medium sized defects of the distal leg, ankle, and foot with low complication rates and donor site morbidity.
RESUMEN
Background: Recalcitrant bone nonunion and osseous defect treatment is challenging and often requires vascularized bone transfer. The medial femoral condyle flap has become an increasingly popular option for reconstruction. The study aims at reviewing its different applications and synthesizing its surgical outcomes. Method: A systematic review including all studies assessing surgical outcomes of free medial femoral condyle flap for bone reconstruction in adults was conducted on January 31, 2023. Flap failure and postoperative complications were synthesized with a proportional meta-analysis. Results: Forty articles describing bony reconstruction in the head and neck, upper limb, and lower limb areas were selected. Indications ranged from bony nonunion and bone defects to avascular bone necrosis. Multiple flaps were raised as either pure periosteal, cortico-periosteal, cortico-cancellous-periosteal, or cortico-chondro-periosteal. A minority of composite flaps were reported. Overall failure rate was 1% [95% confidence interval (CI), 0.00-0.08] in head & neck applications, 4% in the lower limb (95% CI, 0.00-0.16), 2% in the upper limb (95% CI, 0.00-0.06), and 1% in articles analyzing various locations simultaneously (95% CI, 0.00-0.04). Overall donor site complication rate was 4% (95% CI, 0.01-0.06). Major reported complications were: femoral fractures (nâ =â 3), superficial femoral artery injury (nâ =â 1), medial collateral ligament injury (nâ =â 1), and septic shock due to pace-maker colonization (nâ =â 1). Conclusion: The medial femoral condyle flap is a versatile option for bone reconstruction with high success rates and low donor site morbidity.
RESUMEN
BACKGROUND: Managing wounds of the lateral malleolus is challenging owing to limited nearby tissues and possibly injured or inadequate vessels for free flaps, especially in case of underlying infections. Moreover, free flaps require specialized skills and are not suitable for every patient. Therefore, identifying reliable local alternatives is crucial. This retrospective study investigated the efficacy and safety of the distally based peroneus brevis muscle flap in treating complex and infected soft-tissue defects of the lateral malleolus. MATERIALS AND METHODS: A retrospective medical chart review of all patients who underwent a distally based peroneus brevis muscle flap reconstruction in the context of an infected lateral malleolus defect at Geneva University Hospitals between October 2020 and January 2024 was performed. RESULTS: Ten patients underwent lateral malleolus reconstruction using a distally based peroneus brevis muscle flap primarily to address post-traumatic infections. Flap coverage was performed within 4 weeks of infection onset for post-traumatic cases, alongside antibiotic treatment. The defects were moderate in size, with a median width of 2.5 cm and length of 5.5 cm. There were no complete or partial flap failures. All patients regained the ability to walk within 5 days after surgery. CONCLUSIONS: The distally based peroneus brevis muscle flap was efficient in managing complex and infected soft-tissue defects of the lateral malleolus, with control of infection in all patients and minimal donor-site morbidity.

BACKGROUND/AIM: No specific studies on the changes in the incidence of melanoma in the lower limbs and hips have been performed. This article aimed to examine trends in incidence rates of melanoma of the lower extremities in the U.S. PATIENTS AND METHODS: Data from the SEER program provided by the National Cancer Institute were used to examine trends in melanoma incidence from 2000 to 2019. Data analysis was performed from October to December 2022. RESULTS: A total of 192,327 cases of melanoma of the lower limbs and hips were diagnosed from 2000 to 2019 and included in our study. The incidence rate increased from 9.78 to 13.65 cases per 100,000 person-year and by an average annual percent change (AAPC) of 2% (95%CI=1.4-2.9%). The incidence increased by an AAPC of 2.1% in men and 1.7% in women. The incidence among people under 50 remained stable but increased among those over 50 years. Localized stage disease was the only stage where a continuously increasing incidence was observed, with an AAPC of 1.7% (95%CI=0.9-2.5%). Lentiginous melanoma showed the highest incidence trend rate with an AAPC of 2.3% (95%CI=1.0-3.5%). CONCLUSION: The incidence rate of melanoma in the lower limbs and hips increased between 2000 and 2019, with a higher incidence in men, reversing the previously described trend of higher incidence among women. However, incidence among people under 50 remained stable, suggesting the efficacy of prevention campaigns in this population.

Gustilo 3 lower limb fractures represent a significant challenge because of high complication risk. Two management strategies are commonly used for wound coverage until final closure: negative pressure wound therapy (NPWT) and conventional wound dressing (CWD), also described as standard wound coverage without subatmospheric pressure. Understanding their relative effectiveness is essential to improve patient outcomes. The aim of this systematic review and meta-analysis was to compare the efficacy of NPWT and CWD in Gustilo 3 lower limb fracture management, with a focus on overall rates, superficial infection, and deep infection rates. A systematic review of medical research databases was conducted in accordance with PRISMA guidelines. Studies comparing NPWT with CWD for Gustilo 3 fractures were included. Data extraction and quality assessment were performed. Treatment with CWD was associated with significantly higher rates of overall infection [pooled risk ratio (RR): 0.33; 95% confidence interval (CI): 0.14-0.51] and pooled risk difference (RD: 0.27; 95% CI: 0.15-0.38), superficial infection (pooled RR: 0.35; 95% CI: 0.04-0.66), and deep infection (pooled RR: 0.20; 95% CI: 0.02-0.38) compared with NPWT treatment. Overall infection rate remained significantly higher in the CWD group after analyzing only open tibia fractures (pooled RR: 0.35; 95% CI: 0.21-0.48). Nonunion rate was significant higher in the CWD group (pooled RR: 0.30; 95% CI: 0.00-0.59). Flap failure rate was similar in both groups (pooled RR: 0.09; 95% CI: -0.05 to 0.23). NPWT appears to be a reasonable option for wound management in Gustilo 3 lower limb fractures in terms of infection rates.
RESUMEN
BACKGROUND: Skin-grafted free gracilis muscle flaps are commonly used for lower extremity reconstruction. However, the loss of sensory function may lead to increased patient morbidity. This study prospectively analyzed the sensory and neuropathic pain outcomes of neurotized skin-grafted free gracilis muscle flaps used for the reconstruction of lower extremity defects. METHODS: Patients undergoing lower extremity reconstructions between 2020 and 2022 with neurotized skin-grafted free gracilis muscle flaps were prospectively enrolled. Sensation was assessed at 3, 6 and 12 months postoperatively using monofilaments, two-point discrimination, a vibration device, and cold and warm metal rods. Sensations were tested in the center and periphery of the flaps, as well as in the surrounding skin. The contralateral side served as the control. Patients completed the McGill pain questionnaire to evaluate patient-reported neuropathic pain. RESULTS: Ten patients were included. At 12 months postoperatively, monofilament values improved by 44.5% compared to that of the control site, two-point discrimination, cold detection, warmth detection, and vibration detection improved by 36.2%, 48%, 50%, and 88.2%, respectively, at the reconstructed site compared to those at the control site. All sensory tests were significantly better than 3 and 6 months values (p < 0.05), but remained significantly poorer than the control site (p < 0.05). Sensation in the central flap areas were similar to peripheral flap areas throughout the follow-up period (p > 0.05). The surrounding skin reached values similar to the control site at 12 months (p > 0.05). Moreover, 50% of patients reported neuropathic pain at 3 months postoperatively, 40% at 6 months, and 0% at 12 months (p < 0.05). CONCLUSION: Mechanical detection, vibration detection, temperature detection, and two-point discrimination significantly improved over time but without reaching normal sensory function at 12 months postoperatively. Neuropathic pain resolved at 12 months.

Merkel cell carcinoma is an aggressive malignant skin tumor with high recurrence and low survival. Lymph nodal metastases are associated with a worse overall prognosis. Our aim was to assess how lymph node procedures and positivity are influenced by demographic, tumor, and treatment characteristics. The Surveillance, Epidemiology and End Results database was searched for all cases of Merkel cell carcinoma of the skin between 2000 and 2019. Univariable analysis was conducted using the chi-squared test with the aim of identifying differences in lymph node procedures and lymph node positivity for each variable. We identified 9182 patients, of which 3139 had sentinel lymph node biopsy/sampling, and 1072 had therapeutic lymph node dissection. Increasing age, increasing tumor size, and truncal location were associated with higher positive lymph node rates.
