Defects in the distal lower limbs are common in the field of orthoplastic reconstruction. The ankle area presents little subcutaneous tissue and is often affected by high-energy traumas and bone fractures. Wounds in this region are frequently associated with severe edema that might prevent primary closure. Due to its thinness and tension, the skin overlying both the medial and lateral malleoli is prone to necrosis, which can further lead to large soft tissue defects. Vessels, nerves, and tendons can easily become exposed. The reconstructive approach should aim to provide high-quality tissue that is durable enough to withstand the weight-bearing pressures and the friction from shoes, while remaining sufficiently elastic to conform to the shape of the ankle and to permit the foot movement. In this study, we describe the use of an additional propeller flap to reduce skin tension at the recipient site. A superficial circumflex iliac artery perforator (SCIP) flap was utilized to cover a defect below the medial malleolus. However, after flap inset, achieving a primary closure of the proximal wound without tension was not possible. During the dissection of the posterior tibial artery, perforator vessels were identified and preserved. The larger of these vessels was then used to vascularize a propeller flap, which was then rotated toward the defect to aid a tension-free closure. The postoperative course was uneventful. This case may provide a valuable insight into the challenges often faced during wound closure, even after flap inset. Since the flap itself may increase the width of the dissection area, the present case shows the importance of preserving perforator vessels during the proximal dissection since they can allow the harvest of an additional flap to achieve primary closure and further alleviate tension.

Background
In breast reconstruction, arterial coupling has been reported to be more favorable in the thoracodorsal artery (TDA) than the internal mammary artery (IMA). This technique may help overcome anastomosis in a small, deep space. Understanding the arteries' mechanical properties is crucial for breast reconstruction's safety and success.
Methods
Abdominal-based free flap breast reconstructions performed by a single surgeon between 2020 and 2022 were retrospectively analyzed. The patients were classified by microanastomosis technique (handsewn and coupler device) to compare the rate of vascular revision. Histomorphometric analysis of arterial coupling in TDA and IMA was performed in 10 fresh cadavers for comparing wall thickness and composition, including densities of elastic fiber, smooth muscle, and collagen.
Results
A total of 309 patients (339 reconstructed breasts) were included. There were 29 patients in the TDA handsewn group (A), 38 patients in the TDA coupler group (B), and 242 patients in the IMA handsewn group (C). The rates of arterial revision in groups A, B, and C were 0.00% (95%CI: 0.00%–11.03%), 2.5% (95%CI: 0.44%–12.88%), and 1.49% (95%CI: 0.58%–3.77%), respectively, with no statistically significant differences (p-value = .694). Histologically, the thickness of the tunica media and adventitia between IMA and TDA showed no significant difference. The density of elastic fiber was significantly higher in IMA (16.70%) than in TDA (0.79%) (p-value <.001).
Conclusion
The histologic characteristics of TDA are more favorable for arterial coupling than those of IMA. Arterial coupling is a safe option in situations where TDA anastomosis must be performed through a narrow and deep incision.

Introduction
Complex open long bone fractures present a multidisciplinary surgical challenge. Various treatment options are discussed with no consensus. Fibula flaps (FF) are frequently used in maxillofacial surgery, however their use in limb injuries is less common. With the tremendous improvement in microsurgery, orthoplastic surgery gained importance. Our retrospective study aims to assess the long-term results and the quality of life of the patients operated by FF for complex traumatic limb reconstruction.
Patients and Methods
We conducted an observational mono centric retrospective study from the year 2011 to the year 2021. Patients operated for complicated traumatic limb fractures using FF were included in the study. Not only long-term clinical results were evaluated, but also Patient-reported outcome measures (PROM). These included the Lower Extremity Functional Scale (LEFS), Quick Disabilities of the Arm, shoulder and hand (Qdash), and the Visual Analogue Scale (VAS). The statistical analysis was done using the R Software.
Results
Twenty patients were included in our study. 80% achieved complete union with no re fracture rate at a median follow-up of 41 months. All of the patients (n = 4) who underwent amputation were smokers (p = .09), were operated for lower limb fractures (p = .54), and were males (p = 1). The length of hospital stay was associated with an increased duration to complete bony union (p = .01, coefficient = 2.88). At the end of follow-up, the LEFS median score was 67 for the total population and 63.5 for the lower limb reconstructed sub group.
Conclusion
VFF is an important tool in the armamentarium of orthoplastic surgeons. Encouraging long term functional and clinical outcomes were obtained in patients with complex traumatic limb fractures.

Purpose
The superficial temporal artery (STA) and facial artery (FA) are two commonly used recipient vessels when performing free tissue transfer to the head and neck. This meta-analysis compares the impact of recipient vessel location on free flap outcomes in scalp reconstruction.
Methods
A systematic review was conducted following PRISMA-P guidelines using six databases. Studies reporting free tissue transfer using the STA or FA as a recipient vessel for reconstructing scalp defects were included. Outcomes of interest included flap loss, partial flap necrosis, wound dehiscence, venous thrombosis, and infection rates. Quality evaluation was performed using ASPS criteria and the ROBINS-I tool.
Results
Of 3270 identified articles, 12 were included for final analysis. In total, 125 free flaps were identified (75 STA, 50 FA). Pooled analysis demonstrated an overall flap survival rate of 98.4% (STA 98.7% vs. FA 98.0%; p = .782). The mean defect size was significantly greater for flaps using the STA compared with the FA (223.7 ± 119.4 cm2 vs. 157.1 ± 96.5 cm2, p = .001). The FA group had a higher incidence of wound dehiscence than the STA group (14.0% vs. 1.3%, p = .005). However, meta-analysis demonstrated no significant difference in rates of wound dehiscence, flap loss, partial flap necrosis, venous congestion, or postoperative infection between groups.
Conclusion
This is the first systematic review and meta-analysis to assess recipient vessel selection in scalp reconstruction. Our results do not support a single vessel as the superior choice in scalp reconstruction. Rather, these findings suggest that the decision between using the STA or FA is multifaceted, requiring a flexible approach that considers the individual characteristics of each case. Further research is needed to explore additional factors influencing recipient vessel selection, including defect location, radiation therapy, and prior head and neck surgery.

Background
Amputation of the wrist or distal forearm after high-energy trauma due to a crushing mechanism is associated with complex tissue defects, making repair, and reconstruction challenging. Given the difficulty of this type of salvage, patients unfortunately experience a high revision amputation rate. However, a higher quality of life has been reported in patients with successful reconstructions. Herein, we described a protocolized approach for revascularization and reconstruction for functional hand salvage after traumatic amputation from a crushing mechanism using an anterolateral thigh flap (ALT).
Methods
A retrospective review was performed between October 2016 and October 2023 for all patients who underwent single-stage emergent debridement, revascularization, and soft tissue coverage using the ALT after amputation at the level of the wrist or distal forearm secondary to high-energy crush injury. Charts were reviewed for the preoperative Mangled Extremity Salvage Score, intraoperative details including what structures were injured and the reconstructive method performed, and postoperative data such as follow-up duration, outcomes, and complications.
Results
Eleven patients met the inclusion criteria with an average age of 35.5 (21–49) years old. The average size of the skin soft tissue defects was 17.3 × 8 cm (range, length: 13–25 cm, width: 6–13 cm), and all cases had associated injury to the underlying bone, nerves, and blood vessels. The average size of the ALT flap used for reconstruction was 19.2 × 9.8 cm (range, length: 14–27 cm, width: 7–15 cm). All patients had survival of the replanted limb. One patient experienced partial flap necrosis that required secondary debridement and skin graft. Nine patients healed without requiring any additional debridement procedures. Patient follow-up averaged 24.6 (12–38) months. All patients achieved satisfactory functional recovery with Grade II to III of Chen's criteria.
Conclusions
For patients with traumatic crush amputation to the wrist with surrounding soft tissue injury, thorough debridement, revascularization, and reconstruction of amputated limbs can be performed in a single stage using the ALT. A protocolized approach from two institutions is presented, demonstrating improved survival and reduced complications of the traumatized limb with improved long-term patient outcomes.

Background
Instep flaps are commonly used for the reconstruction of weight-bearing areas of the foot. However, in cases of large defects or damage to the instep area, non-instep flaps such as reverse sural flaps (RSF) or free anterolateral thigh flaps (ALTF) can be employed. Previous studies have primarily focused on heel reconstruction when comparing different flaps, without considering the forefoot. This study aims to verify the clinical outcomes of these flaps and determine the appropriate donor site for weight-bearing areas of the foot including forefoot reconstruction.
Methods
In a retrospective study, 39 patients who had undergone flap reconstruction of weight-bearing area defects in the foot with a follow-up period of ≥1 year were included. The patients were categorized into two groups: Group A (n = 19) using instep flaps, and Group B (n = 20) using non-instep flap including RSFs and ALTFs. Surgical outcomes were assessed based on the success of the flap, the presence of partial necrosis, the number of additional surgeries, and complications related to the donor site. Clinical evaluation included visual analogue scale (VAS) and American Orthopedic Foot and Ankle Society (AOFAS) score, and the occurrence of ulcers.
Results
All flaps were successful, while partial necrosis occurred in one case in Group B. There were three reclosures after flap border debridement in both groups and one donor site debridement in Group A. The VAS scores during weight-bearing were 2.0 ± 1.1 and 2.2 ± 1.5 for Groups A and B, respectively (p = .716). The AOFAS scores were 52.8 ± 6.8 and 50.2 ± 12.7 for Groups A and B, respectively (p = .435). The occurrence of ulcers was 0.4 ± 0.9 times for Group A and 0.3 ± 0.7 times for Group B, with no significant difference between the two groups (p = .453).
Conclusion
There was no difference in clinical outcomes between the types of flaps after reconstruction of the forefoot and hindfoot. Therefore, it is recommended to choose the appropriate flap based on factors such as the size of the defect, its location, and vascular status rather than the type of flap.

Objective
This study is an economic evaluation comparing virtual surgical planning (VSP) utilization to free hand mandibular reconstruction (FHR) for advanced oral cavity cancer, for which the cost effectiveness remains poorly understood. The proposed clinical benefits of VSP must be weighed against the additional upfront costs.
Methods
A Markov decision analysis model was created for VSP and FHR based on literature review and institutional data over a 35-year time horizon. Model parameters were derived and averaged from systematic review and institutional experience. VSP cost and surgical time saving was incorporated. We accounted for long-term risks including cancer recurrence and hardware failure/exposure. We calculated cost in US dollars and effectiveness in quality-adjusted-life-years (QALYs). A health care perspective was adopted, discounting costs and effectiveness at 3%/year. Deterministic and probabilistic sensitivity analyses tested model robustness.
Results
In the base case scenario, total VSP strategy cost was $49,498 with 8.37 QALYs gained while FHR cost was $42,478 with 8.27 QALY gained. An incremental cost-effectiveness ratio (ICER), or the difference in cost/difference in effectiveness, for VSP was calculated at $68,382/QALY gained. VSP strategy favorability was sensitive to variations of patient age at diagnosis and institutional VSP cost with one-way sensitivity analysis. VSP was less economically favorable for patients >75.5 years of age or for institutional VSP costs >$10,745. In a probabilistic sensitivity analysis, 55% of iterations demonstrated an ICER value below a $100,000/QALY threshold.
Conclusions/Relevance
VSP is economically favorable compared to FHR in patients requiring mandibular reconstruction for advanced oral cancer, but these results are sensitive to the patient's age at diagnosis and the institutional VSP cost. Our results do not suggest if one “should or should not” use VSP, rather, emphasizes the need for patient selection regarding which patients would most benefit from VSP when evaluating quality of life and long-term complications. Further studies are necessary to demonstrate improved long-term risk for hardware failure/exposure in VSP compared to FHR.

Epidermolysis bullosa (EB) encompasses a range of rare genetic dermatological conditions characterized by mucocutaneous fragility and a predisposition to blister formation, often triggered by minimal trauma. Blisters in the pharynx and esophagus are well-documented, particularly in dystrophic EB (DEB). However, there have been few reports of mucocutaneous squamous cell carcinoma (SCC) in the head and neck region, for which surgery is usually avoided. This report presents the first case of free jejunal flap reconstruction after total pharyngolaryngoesophagectomy for hypopharyngeal cancer in a 57-year-old patient with DEB. The patient with a known diagnosis of DEB had a history of SCC of the left hand and esophageal dilatation for esophageal stricture. PET-CT imaging during examination of systemic metastases associated with the left-hand SCC revealed abnormal accumulation in the hypopharynx, which was confirmed as SCC by biopsy. Total pharyngolaryngoesophagectomy was performed, followed by reconstruction of the defect using a free jejunal flap. A segment of the jejunum, approximately 15 cm in length, was transplanted with multiple vascular pedicles. The patient made an uneventful recovery postoperatively and was able to continue oral intake 15 months later with no complications and no recurrence of SCC in the head and neck region. While cutaneous SCC is common in DEB, extracutaneous SCC is relatively rare. In most previous cases, non-surgical approaches with radiotherapy and chemotherapy were chosen due to skin fragility and multimorbidity. In the present case, vascular fragility and mucosal damage of the intestinal tract were not observed, and routine vascular and enteric anastomoses could be performed, with an uneventful postoperative course. Our findings suggest that highly invasive surgery, including free tissue transplantation such as with a free jejunal flap, can be performed in patients with DEB.

Total pharyngolaryngectomy is sometimes combined with total glossectomy for advanced hypopharyngeal or cervical esophageal cancers involving the tongue base. The optimal reconstruction method for total pharyngolaryngectomy with total glossectomy has not been established due to a considerable diameter mismatch between the floor of mouth and the esophageal stump. This report describes two reconstruction methods using free jejunal transfer.
Methods
Five consecutive patients who underwent total pharyngolaryngectomy with total glossectomy were included, with a mean age of 67.0 (range 55–75) years. Primary tumors included tongue, hypopharyngeal, cervical esophagus, and laryngeal cancers. The mean defect size was 17.0 (16–19) × 6.8 (6–7) cm. Surgical techniques involved either a simple incision or a two-segment method to address the size mismatch between the jejunum and the floor of mouth. In the simple incision method, a longitudinal cut was made to the antimesenteric or paramesenteric border of a jejunum wall to expand the orifice. In the two-segment method, a jejunal graft was separated into two segments to reconstruct the floor of mouth and the cervical esophagus, and these segments were connected with a longitudinal incision to the cervical esophageal segment to form a funnel-shaped conduit.
Results
Of the five patients, three underwent the simple incision method and two the two-segment method. Postoperative pharyngoesophagography showed a smooth passage for all patients. Postoperative courses were uneventful except for one flap loss due to arterial thrombosis. Four patients achieved oral feeding, while one became gastric-tube dependent. At a mean follow-up of 22.1 (4–39) months, one patient required tube feeding, two tolerated full liquid, and two consumed a soft diet.
Conclusions
Both the simple incision and two-segment methods achieved satisfactory swallowing function. The choice between these reconstruction methods may depend on the extent of resection of the posterior pharyngeal wall.
