Introduction: Biodegradable Temporizing Matrix (BTM) is a new synthetic dermal substitute suitable for wound closure and tissue regeneration. The data in paediatric population remain limited. The study purpose is to review the indications for BTM application in paediatric patients, evaluate the short-term and long-term results, including complications and functional outcomes, as well as to share some unique observations regarding the use of BTM in paediatric population. Patients and Methods: Patients undergoing reconstructive surgery and BTM application during the last three years were included. Data collected included patient demographics, primary diagnosis, previous surgical management, post-operative complications and final outcomes. BTM was used in 32 patients. The indications varied including epidermolysis bullosa (n = 6), burns (n = 4), trauma (n = 7), infection (n = 4), ischemia or necrosis (n = 11). Results: The results were satisfying with acceptable aesthetic and functional outcomes. Complications included haematoma underneath the BTM leading to BTM removal and re-application (n = 1), BTM infection (n = 1) and split-thickness skin graft failure on top of BTM requiring re-grafting (n = 2). Conclusions: BTM can be a good alternative to large skin grafts, locoregional flaps or even free flaps. The big advantages over other dermal substitutes or skin grafts are that BTM is less prone to infection and offers excellent scarring by preserving the normal skin architecture. Specifically in children, BTM might not require grafting, resulting in spontaneous healing with good scarring. In critically ill patients, BTM reduces the operation time and there is no donor site morbidity. BTM should be considered in the reconstructive ladder when discussing defect coverage options in children and young people. Full article

Refractory full-thickness macular holes (rFTMHs) present a significant challenge in vitreoretinal surgery, with reported incidence rates of 4.2–11.2% following standard vitrectomy with internal limiting membrane (ILM) peeling and gas tamponade. Risk factors include large hole size (>400 µm), chronicity (>6 months), high myopia, incomplete ILM peeling, and post-operative noncompliance. Multiple surgical techniques exist, though comparative evidence remains limited. Current options include the inverted ILM flap technique, autologous ILM transplantation (free flap or plug), lens capsular flap transplantation (autologous or allogenic), preserved human amniotic membrane transplantation, macular subretinal fluid injection, macular fibrin plug with autologous platelet concentrates, and autologous retinal transplantation. Closure rates range from 57.1% to 100%, with selection depending on hole size, residual ILM, patient posturing ability, etc. For non-posturing patients, fibrin plugs are preferred. Residual ILM cases may benefit from extended peeling or flap techniques, while large holes often require scaffold-based (lens capsule, amniotic membrane) or fibrin plug approaches. Pseudophakic patients should avoid posterior capsular flaps due to lower success rates. Despite promising outcomes, the lack of randomized trials necessitates further research to establish evidence-based guidelines. Personalized surgical planning, considering anatomical and functional goals, remains crucial in optimizing visual recovery in rFTMHs. Full article

Background: Huriez syndrome is a rare hereditary skin disorder marked by early-onset sclerodactyly, hyperkeratosis of the palms and soles, and nail dysplasia. A key concern is the early and aggressive development of cutaneous squamous cell carcinoma (SCC), typically affecting the dorsal aspects of the hands. Methods: This narrative review summarizes clinical features, genetic aspects, and oncologic implications of Huriez syndrome. A systematic search was conducted in PubMed and Scopus, including English-language articles published up to May 2025. Relevant case reports and small case series were analyzed. Results: Seven patients (58.3%) underwent multiple surgeries due to recurrent or bilateral disease. Six patients (50%) required amputations, including finger, hand, and arm amputations, with no foot amputations reported. Reconstruction after oncological resection was performed in six patients (50%) using skin grafts (3), pedicled flaps (2), or free flaps (1). Amputation was mainly for advanced disease, with radial forearm flaps used for reconstruction. All flaps remained disease-free. Five cases (41.6%) had a history of local recurrence. Conclusions: The early diagnosis of Huriez syndrome is crucial to enable the surveillance and timely treatment of SCC. A multidisciplinary team including dermatologists, oncologists, plastic surgeons, and geneticists is recommended. Further research is needed to clarify genetic mechanisms and develop early detection strategies to improve outcomes. Full article

Background: Robotic deep inferior epigastric artery perforator (DIEP) flap surgery is a technique used for autologous breast reconstruction to maintain the integrity of the rectus abdominis muscle while also utilizing robotic assistance for flap harvest. This study assesses postoperative outcomes of patients undergoing robotic DIEP flap reconstruction through the measurement of postoperative pain, narcotics use, and antiemetic usage. Methods: A retrospective analysis was performed for patients undergoing robotic DIEP flap breast reconstruction between March 2024 and March 2025. Postoperative pain scores (1–10 scale), narcotics usage (measured in oral morphine equivalents), antiemetic usage, and complications were recorded. Patient outcomes were compared to a control group of 40 patients who had undergone abdominal-based free flap breast reconstruction. Results: Overall, 14 patients underwent robotic DIEP flap breast reconstruction, representing 24 breasts. The average patient age was 56.5 (range: 30–73). Ten patients underwent bilateral breast reconstruction, and four underwent unilateral breast reconstruction. The average length of stay postoperatively was 4.86 days (±1.23 days), and the return of bowel function occurred in 1.29 days (±0.47 days). No patients experienced an unplanned return to the OR or flap failure. Average pain scores on postoperative day 1 (POD1), 2 (POD2), and 3 (POD3) were 4.0 (±0.6), 3.4 (±0.6), and 2.93 (±0.5), respectively. Average antiemetic usage totalled 1.25 doses (±0.25). Average daily OME use was 27.7 (±5.0) for POD1, 25.96 (±6.3) for POD2, and 21.23 (±7.11) for POD3. This averaged to a total hospital OME use of 74.9 (±15.7) per patient. Patients undergoing robotic DIEP flap reconstruction required a significantly lower narcotics dosage, as well as a lower antiemetic dosage, during the first three days postoperatively compared to the control abdominal free flap group. Average pain scores in the robotic DIEP flap reconstruction patient group were also significantly decreased, specifically in POD2 and POD3. Conclusions: The robotic DIEP flap offers advantages in autologous breast reconstruction compared to other abdominal free flap reconstructive methods. In this limited retrospective study, the use of the robotic DIEP flap lowers chances of flap failure and complications, while also improving narcotics use, antiemetic use, and postoperative pain.

Background/Objectives: The gold standard of treatment for both melanoma and non-melanoma skin cancers is wide surgical resection to obtain oncological radicality, which occasionally results in functional or aesthetic impairment, potentially affecting quality of life. Despite the increased complexity of the technique, extended duration of hospitalization, and prolonged surgical operative times, microsurgery can facilitate the reconstruction of locally invasive skin cancers following ablative surgery and may yield superior functional and aesthetic outcomes. Consequently, microsurgical reconstruction is more likely to be necessary if a large skin tumor requires excision. However, the impact of this extensive and complex procedure on patients with skin cancer has not yet been fully elucidated. The objective of this research was to critically analyze the utilization of free flap reconstruction subsequent to skin cancer therapy. Through a comprehensive examination of published data, this study aimed to assess the potential benefits and drawbacks associated with this reconstructive approach. Methods: A systematic review of studies that were published from January 2004 to May 2024 was conducted using the MEDLINE online database search. To present an evidence summary and provide a systematic approach and quality assessment, the GRADE^® rating was applied to the results. Results: This review summarizes the oncological and clinical data, including previous interventions, adjuvant and neoadjuvant therapies, nodal status, distant metastasis, and follow-up time. Surgical outcome parameters such as healing time, flap survival, revision rate success, and minor and major complications were documented. Along with the findings, a quality assessment of the studies was also provided. Conclusions: This systematic review underscores the extensive use and efficacy of microsurgery for reconstruction after skin cancer excision; however, the literature remains limited by inconsistent reporting of oncological outcomes and the lack of a standardized approach to evaluate the impact of free flap reconstruction on both immediate and long-term cancer-specific results.

Background: Surgical care in conflict regions like Tigray, Ethiopia, faces severe challenges due to limited resources, infrastructural deficiencies, and high trauma burden. From 2019 to 2023, a multidisciplinary team conducted five humanitarian missions focusing on orthoplastic reconstruction of extremity and mandibular injuries from high-energy gunshot trauma. Methods: A retrospective analysis was performed on 98 patients who underwent free or pedicled flap reconstruction. Data included demographics, flap type, technique, complications, follow-up, and early clinical outcomes score as well as mobility scores. Flaps were harvested using loupes anastomosis performed using microscopes, depending on availability. Results: Among 98 patients (25.5% female, 74.5% male), 69 free flaps and 38 pedicled flaps were performed. Free fibula flaps (n = 54) included 33 mandibular and 21 extremity reconstructions. Additional flaps included ALT, gracilis, and LD flaps. Pedicled flaps included 18 fibula and 20 ALT/LD flaps. Mean age was 35.5 years; mean operative time was 429.5 min, with mandibular fibula transfers being longest. Microsurgical techniques were used in 34% of cases. Median follow-up was 10 months. Microsurgical complications occurred in 18.4%, mainly in fibula transfers (25.9%). Non-microsurgical issues included wound infections (n = 15), graft loss (n = 3), and bleeding (n = 5). Flap loss occurred in 16.3% overall. Early clinical outcome results were good (30.6%), acceptable (28.6%), and moderate (24.5%). Conclusions: Orthoplastic reconstruction using both free and pedicled flaps is feasible in low-resource, conflict settings. Despite infrastructural challenges, functional outcomes were achievable, supporting the value of adaptable microsurgical strategies in humanitarian surgery. Full article

Background: Primary malignant bone tumors among adolescent patients are most commonly associated with burdensome surgeries that can severely affect young patients’ early life. To this day, despite available autologous tissue donor sites, cement spacers or endoprostheses are still most commonly used as a form of reconstruction of post-resection defects. Methods: The study group includes 20 adolescent patients diagnosed with Osteosarcoma or Ewing Sarcoma involving the upper limbs. The inclusion criteria were as follows: primary malignant bone tumors sensitive to neoadjuvant chemotherapy, tumors not infiltrating major blood vessels and nerves, and the appliance of the microsurgical free flap as a reconstructive method. Poor tumor response to neodajuvant chemotherapy or patients with incomplete follow-up were excluded from this study. To achieve the functional reconstruction of post-resection defects, fibula free flaps were applied. In cases of resection, including the metaphysis of a long bone, a modification of the flap harvest was applied in order to prevent arthrodesis. The MSTS (Musculoskeletal Tumor Society Scoring System) scale was used as a functional outcome measurement tool. Results: The reported outcomes of this study prove the efficiency of the treatment’s approach of combining the resection of the tumor with subsequent microsurgical restoration with the use of autologous tissues. The average score on the MSTS scale, which assesses the functional outcome, was 26.8/30 points, which indicates great motor outcomes. There were no reports of local recurrence during follow-up. Conclusions: Patients with primary malignant bone tumors in the upper limbs can benefit from microsurgical techniques, which are highly customized; effective; and give sufficient functionality following extensive resection.

Background: Microsurgery is a highly complex and technically demanding field within reconstructive surgery, with outcomes heavily dependent on meticulous planning, precision, and postoperative monitoring. Over the last five years, artificial intelligence (AI) has emerged as a transformative tool across all phases of microsurgical care, offering new capabilities in imaging analysis, intraoperative decision support, and outcome prediction. Methods: A comprehensive narrative review was conducted to evaluate the peer-reviewed literature published between 2020 and May 2025. Multiple databases, including PubMed, Embase, Cochrane, Scopus, and Web of Science, were searched using combinations of controlled vocabulary and free-text terms relating to AI and microsurgery. Studies were included if they described AI applications during the preoperative, intraoperative, or postoperative phases of microsurgical care in human subjects. Discussion: Using predictive models, AI demonstrated significant utility in preoperative planning through automated perforator mapping, flap design, and individualised risk stratification. AI-enhanced augmented reality and perfusion analysis tools improved precision intraoperatively, while innovative robotic platforms and intraoperative advisors showed early promise. Postoperatively, mobile-based deep learning applications enabled continuous flap monitoring with sensitivities exceeding 90%, and AI models accurately predicted surgical site infections, transfusion needs, and long-term outcomes. Despite these advances, most studies relied on retrospective single-centre data, and large-scale, prospective validation remains limited. Conclusions: AI is poised to enhance microsurgical precision, safety, and efficiency. However, its integration is challenged by data heterogeneity, generalisability concerns, and the need for human oversight in nuanced clinical scenarios. Standardised data collection and multicentre collaboration are vital for robust, equitable AI deployment. With careful validation and implementation, AI holds the potential to redefine microsurgical workflows and improve patient outcomes across diverse clinical settings. Full article

Background/objectives: Major head and neck oncologic surgeries requiring microvascular reconstruction frequently result in complications such as perioperative blood transfusion (PBT). Not only are blood products overutilized and associated with risks, but preoperative anemia is both a modifiable and predisposing factor for PBT. Our objective was to assess risk factors for PBT and determine a high-risk preoperative hemoglobin to inform transfusion stewardship practices. Methods: Patients that underwent head and neck cancer free flap reconstruction (n = 363) between 2012 and 2019 were included. Univariable and multivariable analyses evaluated predictors of PBT. Results: Overall, 11% of patients were anemic and 19% were transfused. Mean preoperative hemoglobin was significantly lower in the PBT group (128 g/L vs. 145 g/L, p < 0.0001). In our multivariable model, lower preoperative hemoglobin (odds ratio [OR] = 0.94), higher T stage (OR = 2.65), and lower body mass index (BMI) (OR = 0.89) increased the odds of PBT. Adjusting for staging and BMI, the OR of PBT was increased below 120 g/L hemoglobin. Higher mean units of PBT were administered for hemoglobin below 150 g/L with a large inflection below 120 g/L (p < 0.0001). Conclusions: Low preoperative hemoglobin is the strongest predictor of PBT in major head and neck cancer surgery. Recognizing and managing anemia is essential in surgical planning. Full article

Background and Objectives: Penile tissue loss, which can be an acquired condition due to trauma or infection, but is also seen in congenital anomalies, is a rare condition in children. A standard surgical approach is often not possible due to the different degrees and etiologies of penile tissue loss. The continuing growth and the presence of various congenital anomalies in children require a different penile reconstruction approach than in adults. We aimed to share our experience and surgical results with children in whom we performed penile reconstruction with different techniques due to penile tissue loss. Materials and Methods: Ten cases that underwent penile reconstruction between 2018 and 2023 were evaluated retrospectively. Age at initial operation, associated anomalies, surgical technique, and other related surgical attempts, as well as functional and cosmetic results, were recorded. Results: Ten boys aged between 6 months and 17 years underwent phalloplasty due to penile tissue absence. In six cases, penile tissue loss was due to acquired causes, and in four cases, congenital anomalies were the reason. The most common cause of penile tissue loss was circumcision complications. In four cases, penile reconstruction was achieved by mobilization of the remaining corpus cavernosum tissues, in two cases, the cavernous tissue was adequate and repaired with glansplasty and penile skin graft. Phalloplasty was performed by tubularization of a skin and subcutaneous fat flap, removed from the pubic region and scrotal region, in two cases. A microvascular radial forearm flap was performed in a 17-year-old patient with penile tissue loss because of trauma, and a free skin flap taken from the forearm was used for penile reconstruction. Thirty percent of patients required a second surgery. Urinary continence was present in eight of the cases. Although four cases were classified as cosmetically unsatisfactory in our evaluation, all patients and their families reported being satisfied with the cosmetic results. Conclusions: Penile reconstruction for penile tissue loss in children should be performed in clinics where different scenarios can be applied. With maximum preservation and mobilization of existing cavernous tissues, temporary penile reconstruction with local flaps should be performed in young children at an early stage to minimize the psychological effects of penile absence. Although an esthetically perfect result cannot be guaranteed, patients and families are generally satisfied with the outcome. Full article

Background: Steal syndrome in the setting of microvascular reconstruction refers to a phenomenon whereby blood flow is diverted from the native tissue to the free flap, leading to ischemia and potential limb loss. In the present study, we aim to comprehensively evaluate the occurrence and management of steal syndrome in free flap reconstruction of the lower extremities. Methods: A thorough literature search was conducted across the MEDLINE, Embase, Cochrane Library, and Scopus databases up to 29 January 2025. Studies were selected based on predefined inclusion criteria focusing on free flap microvascular reconstruction in the lower extremities with a focus on steal syndrome. Two independent reviewers assessed and extracted data. Results: Three studies were included, involving seven patients, with a mean age of 65.66 ± 5.89 years, who developed steal syndrome following free flap microvascular reconstruction. The most common revision involved below-the-knee amputation (BKA) due to ischemic complications. Comorbidities such as peripheral vascular disease (PVD), diabetes, and hypertension were present in all cases. The majority of anastomoses (85.7%) were end-to-side (ETS), with only one case utilizing a flow-through configuration. The majority of cases (n = 5, 71.4%) were reconstructed using latissimus dorsi (LD) flaps, with the remaining two cases using rectus abdominis (n = 1) and gracilis (n = 1) flaps. The recipient vessel was the anterior tibial artery in two patients (28.6%), the dorsalis pedis artery in two patients (28.6%), and the popliteal artery in three patients (42.9%). The most common salvage procedure was below-the-knee amputation (BKA), performed in four patients (57.1%). One patient required revision of the venous anastomosis and flap debridement, followed by a Chopart amputation (n = 1, 14.3%). Conclusions: The occurrence of steal syndrome in free flap microvascular reconstruction of the lower extremities is rare but can lead to significant complications, including amputation. The findings indicate that steal syndrome is more likely in patients with pre-existing vascular conditions such as PVD and diabetes. While surgical technique and flap type may influence its development, further studies are needed to identify specific anatomical and clinical predictors. The absence of a unified treatment guideline underscores the need for further investigation into effective management strategies to prevent amputation and optimize patient outcomes. Full article

Background: The proportion of oropharyngeal cancers, especially those that are HPV-associated, is increasing, and both surgery and RT are considered effective initial treatments for early-stage oropharyngeal cancer, regardless of p16 status. However, there are still many unknowns regarding the long-term prognosis after initial treatment, the incidence rate of multiple cancers, and the relationship with p16 status. Methods: We retrospectively analyzed 94 cases of T1/2N0 oropharyngeal squamous cell carcinomas (OPSCCs) treated with surgery or radiotherapy between January 2000 and December 2012 at the Japan National Cancer Center Hospital East. The study items include long-term prognosis, p16 status, and the proportion of patients with multiple cancers after receiving treatment for oropharyngeal cancer. Results: The patients included 80 men and 14 women, whose median age was 68 (35–92). The median follow-up time was 2131 days. T1N0 cancer was observed in 34 patients and T2N0 in 60 patients. Surgery was performed for 74 patients, and radiotherapy for 20 patients. Of the patients who underwent surgery, 57 underwent transoral surgery, and 17 underwent pharyngectomy via transcervical approach. Nine of the 17 patients underwent partial pharyngectomy with free-flap reconstruction. The 5-year overall survival rates were 74.9 and 51.0% (p = 0.035); the 5-year disease-specific survival rates were 86.0 and 64.5% (p = 0.116); and the 5-year local control rates, 76.5 and 59.1% (p = 0.106) for the surgery and radiotherapy groups, respectively. Furthermore, 54 (57.4%) of the 94 cases suffered from multiple primary cancers, of which 29 (30.9%) were in the head and neck region and all were metachronous. Conclusions: Initial surgery for T1/2N0 OPSCCs is a proper therapeutic strategy considering the better overall survival and high incidence of multiple primary cancers. Full article

Background: Reconstructive surgery with free flaps is a fundamental component in head and neck surgery, but flap failure remains a significant concern. The hemoglobin, albumin, lymphocyte, and platelet (HALP) score is a prognostic factor commonly applied in the evaluation of patients suffering from malignant tumours. This score has emerged as a potential preoperative risk assessment tool; however, its predictive accuracy for free flap failure has not been fully evaluated. The potential of this formula, in the cervical–facial reconstructive area, has not yet been well studied in the international literature. Methods: This retrospective study included patients who had undergone free flap reconstruction in the maxillofacial surgery departments of Perugia and Ancona over the past ten years. To optimize the HALP formula, advanced machine learning technologies, mainly the Julius AI platform, were applied. The HALP formula was refined through three phases: the original formula, a weighted version, and the final “Modified HALP.” Predictive performance was assessed using ROC curve analysis, multivariate logistic regression, and internal validation. Results: The final version of the HALP score, created in the present study, achieved an AUC-ROC of 0.95 (95% CI: 0.91–0.99), outperforming the original and weighted versions. At the optimal cut-off, the final “Modified” HALP score demonstrated 90.91% sensitivity and 92.36% specificity, remaining an independent predictor of flap failure after adjusting for confounders. Conclusions: The aim of the study was to optimize the HALP score by integrating clinical information with the aim of making significant progress in the prediction of failure in reconstructive flaps. The Modified HALP score emerges as a powerful tool for preoperative risk stratification in free flap surgery, potentially improving patient outcomes through targeted interventions. Future research should focus on external validation and exploring the underlying biological mechanisms. Full article

Background: The Profunda Artery Perforator (PAP) flap is a viable alternative to the Deep Inferior Epigastric Perforator (DIEP) flap, particularly for patients with low BMI and therefore insufficient abdominal tissue. To reduce the high complication rate, especially in our low BMI patient population, we have adapted the use of the vertical skin island design. This study compares complication rates and long-term outcomes of vertical versus horizontal skin island designs in PAP flap breast reconstruction. Methods: This prospective, single-center study included 20 patients who underwent PAP flap breast reconstruction. Quality of life and scar quality were assessed using the BREAST-Q and POSAS questionnaires. Additionally, the cosmetic outcomes were analyzed by four plastic surgeons. Results: Mean BMI in the vertical group was 23.9 kg/m² and 22.7 kg/m² in the horizontal group. Mean flap weight was 326 g for the vertical group and 355 g for the horizontal group. Fewer complications were observed at the donor site in the vertical group (Clavien–Dindo Classification 3b at donor site: p = 0.25). The BREAST-Q evaluation revealed significantly better results regarding the psycho-social well-being (p = 0.04) in patients with the horizontalskin island design. Scar evaluation using the POSAS revealed that the scar was perceived as thinner (p = 0.02), less pigmented (p = 0.03), and showed less relief (p = 0.02) in the vertical group. No significant difference was observed in the overall scar assessment by observers (p = 0.46). The aesthetic analysis by plastic surgeons showed significantly better results in the horizontal group. Conclusions: The vertical skin island design in PAP flap breast reconstruction was associated with lower complication rates and better scar quality compared to the horizontal design. Surgeons, however, rated the overall aesthetic outcome of the vertical design less favorably. These findings highlight the importance of balancing donor site morbidity with overall aesthetic results.

Head and neck cancer (HNC) remains a major global health issue. It is closely linked to smoking, alcohol use, and HPV infection. Nutritional and metabolic factors significantly influence surgical outcomes in these patients, especially when undergoing extensive resections and microsurgical free flap reconstruction. This comprehensive review aims to evaluate how perioperative nutritional status—particularly body mass index (BMI), serum albumin and prealbumin levels, and enteral vs. oral feeding strategies—affects complication rates, wound healing, surgical duration, and overall recovery. Poor nutritional status is associated with increased complication rates, prolonged surgery, impaired wound healing, and higher perioperative mortality. Both high and low BMI negatively impact surgical outcomes. Obesity is linked to protracted surgery and increased blood loss, while underweight patients have higher perioperative mortality. Optimizing perioperative nutrition is important for improving surgical outcomes in HNC patients. A multidisciplinary approach is necessary to tailor nutritional support and enhance recovery. Further research should focus on long-term weight management strategies and identifying biomarkers predictive of surgical success. Full article
