Double-Flap Elevation From the Ipsilateral Lower Extremity: The Anterior Approach to Fibula Osteo-Cutaneous Flap Elevation.

ABSTRACT: The free fibular flap has been elevated by a "lateral approach" from the posterior edge of the peroneal muscle for more than 40 years. However, in this approach, the surgical view is limited because flap elevation in mandibular reconstruction is performed simultaneously with tumor resection in the supine position, even when using positioning pillows. We herein propose an "anterior approach" as a new surgical method. We retrospectively investigated free fibular flap surgeries performed using the anterior approach, which consists of three anterior approaches, over a seven-year period. First, to avoid the course of the superficial peroneal nerve, the crural fascia was incised 1-2 cm posterior to the anterior edge of the peroneal muscle. The anterior edge of the peroneus muscle is detached from the anterior intermuscular septum. After performing osteotomies distal and proximal to the fibula, the interosseous membrane was incised from the anterior view. Pulling out the fibula to the anterior space between the anterior intermuscular septum and the peroneal muscle made the surgical field shallow. No postoperative superficial or deep peroneal nerve palsies were found in the 55 patients. Only one tourniquet was used in 31 of the 55 cases (56.4%), with an average of 95 min. Twenty-four patients (43.6%) required a second tourniquet 38 min after an interval. Only one tourniquet was used in 25 of the 30 (83.3%) cases in the last 3 years. Moreover, double flaps were used in 21 cases (38.2%), all of which involved ipsilateral ALT flaps. In 18 cases, double-flap elevation and prefabrication were successfully finished before the completion of tumor resection by otorhinolaryngologists.

Free medial plantar flap connection with a posterior tibial artery flap and its modification for combined dorsal and plantar foot defects - two case reports.

Reconstruction of large soft tissue foot defects were considered a difficult issue due to weight-bearing function of the foot. The reconstruction becomes more difficult when both plantar and dorsal soft tissues are involved. The options for the reconstruction were variable, in 2016 Hao Wu et al. presented a combined flap for coverage of combined fore-foot plantar and dorsal soft tissue defects. We used combined flaps in two cases and present our experience in this article.

Free vascularized medial femoral condyle periosteal flaps in the ankle and foot region: A narrative review.

OBJECTIVES: The objective of this study was to determine the role and reliability of the free medial femoral condyle (MFC) flap (MFCF) in demanding foot and ankle reconstruction procedures. MATERIALS AND METHODS: A search of the MEDLINE, PubMed, and Embase electronic databases was performed according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines between January 2008 and September 2023. Articles concerning free MFC bone flaps for reconstruction of the foot and ankle regions were included. Outcomes of interest included flap failure, complications, union rate, time to union, and functional scores. RESULTS: Twenty studies involving 131 patients met the inclusion criteria. The most common clinical indications for the free MFCF were nonunion, avascular necrosis, and osteomyelitis. The most common sites of nonunion were tibiotalar arthrodesis (50%) and subtalar arthrodesis (33%). Overall, the bony union rate was 93.1%, with a mean time to union of 14.6±0.1 weeks. There were no flap failures reported. Postoperative complications were observed in 39 (29.7%) cases (e.g., delayed donor site wound healing, flap debulking, medial condyle osteonecrosis, and donor site numbness), with 21 (16%) patients requiring further operative intervention. No major donor or recipient site morbidity occurred, except for one case. CONCLUSION: Free MFCFs offer a versatile and dependable choice for cases of foot and ankle reconstruction, displaying favorable rates of bone fusion and acceptable complication rates. Existing literature indicates that MFC reconstruction in the foot and ankle is not associated with significant morbidity at the donor or recipient sites. The pooled data demonstrated a 93% success rate in achieving bone fusion in the foot and ankle region, supporting the view that it can be considered another option of treatment.

Limb Salvage Using Microsurgical Free Tissue Transfer in Severe Frostbite.

PURPOSE: Frostbite is often managed conservatively; however, in severe cases, microsurgical free tissue transfer is required for soft tissue coverage and limb salvage. Given its rarity, the techniques and outcomes of these cases are not well described. The purpose of this report is to present the largest case series, to date, of frostbite injuries requiring microsurgical reconstruction for limb salvage. METHODS: A single-center retrospective review was conducted of all patients who underwent free tissue transfer by a single surgeon from 2008 to 2022. Patients of all ages were included if they suffered a frostbite injury requiring free tissue transfer. Demographics, operative details, and surgical outcomes were recorded. RESULTS: Eight patients with frostbite injuries were included in the report. Patients had frostbite injuries either to the lower extremities (n = 4) or to both upper and lower extremities (n = 4). Sixteen free flaps were done in total including four paired chimeric and eight single free flaps. Flap recipient sites included knees (n = 5), foot/ankle (n = 3), dorsal hands (n = 2), and thumbs (n = 2). All 16 flaps survived. Five patients had complications: four with major complications requiring operative management and two with minor complications requiring conservative management. Mean follow-up time was 505.7 days (range 115-1564). All lower extremity reconstructions were able to weight-bear at an average of 125.2 days post-injury (range 87-164). CONCLUSIONS: This case series demonstrates that free tissue transfer is a robust option for soft tissue coverage and functional limb salvage in patients with severe frostbite injuries to both upper and lower extremities.

A comparison of postoperative outcomes based on recipient vessels in scalp free flap reconstruction: A systematic review and meta-analysis.

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.

Propeller flap's assisted recipient site closure after free SCIP flap coverage of medial ankle defect: A case report.

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.

Free Fibular Osteocutaneous Flap Combined With Simultaneous Tendon Reconstruction for Midfoot Restoration After Myoepithelial Carcinoma Resection.

ABSTRACT: Myoepithelial carcinomas of soft tissue are rare, and most are malignant. The optimal treatment is surgical excision. The arches of the foot are a composite structure responsible for weight bearing and pressure distribution, so it is a vast challenge in reconstruction. We report a case of reconstruction of the midfoot with a free fibular bone flap and tendon graft. We review the literature to compare various options in foot reconstructions and sort out the outcomes of different bone flaps. The free fibula osteocutaneous flap is the superior choice for midfoot reconstruction owing to its sufficient length, strength, flexible skin paddles, easy-to-withstand osteotomy, and simultaneous tendon graft harvesting.

Free medial femoral condyle osteocutaneous flap for repairing stage IIIB osteonecrosis of the lunate: a case report.

BACKGROUND: There are several surgical options for osteonecrosis of the lunate, and confirming the effectiveness of various surgical methods remains challenging. Here, we present a case of stage IIIB osteonecrosis of the lunate repaired with a free medial femoral condyle osteocutaneous flap. CASE PRESENTATION: A 43-year-old male construction worker was admitted to our hospital due to right wrist pain, impaired mobility, and pain aggravated by activity for 10 months. The patient was diagnosed with stage IIIB osteonecrosis of the lunate based on the orthopantomogram and magnetic resonance imaging of the right wrist. Considering the patient's medical history, physical examination, auxiliary examination, and wishes, reconstruction was performed using a free medial femoral condyle osteocutaneous flap. After the flap survived completely, the K-wires were removed one month after the operation, the external brace was removed two months after the operation, and functional wrist rehabilitation was initiated. After six months of follow-up, the wrist swelling and pain resolved, and the reconstructed lunate bone was viable. Additionally, the last follow-up was conducted in the sixth month after surgery; the affected hand grip strength improved from about 70% (28 kg) to 80% (32 kg) compared with the healthy side (40 kg); the visual analog scale score decreased from 6.5 points before the operation to 1 point; and the MAYO score increased from 60 points before the operation to 85 points. CONCLUSIONS: The success of this case reinforces the potential of the free medial femoral condyle osteocutaneous flap as a new treatment option for stage IIIB osteonecrosis of the lunate and further expands the existing treatment options. Using a free medial femoral condyle osteocutaneous flap to reconstruct the lunate and restore the carpal anatomy may.

Comparison of instep and non-instep flap in the reconstruction of the weight-bearing portion of the forefoot and heel.

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.

Long-term outcome of fibula flaps in complex limb reconstruction compared to alternative procedures, a median follow up of 41 months.

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.

Single-staged revascularization and reconstruction after crush injury of the wrist and distal forearm: A protocolized approach.

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.

The free vastus lateralis-And conjoined vastus lateralis anterolateral thigh/tensor fascia lata flap for oncological chest wall reconstruction.

INTRODUCTION: A reconstructive option for extensive chest wall reconstruction is the free myocutaneous vastus lateralis muscle (VL) flap which can be performed in isolation or in conjunction with a fasciocutaneus anterolateral thigh (cVLALT) and/or myofasciocutaneous tensor fascia lata flap (cVLTFL). We aimed to directly compare the outcomes of these reconstructive options. METHODS: Patients who underwent oncological chest wall reconstruction with a free VL, cVLALT, or cVLTFL flap between February 2010 and 2022 were included in this retrospective study. Patient demographics, surgical characteristics, as well as medical and reconstructive outcomes, were evaluated. The operative outcomes between myocutaneous VL, cVLALT, and cVLTFL flap reconstructions were compared. RESULTS: A total of 41 patients underwent chest wall reconstruction with a free myocutaneous VL (n = 25; 61%), cVLALT (n = 14; 34%), or cVLTFL Three acute flap thromboses occurred in the entire cohort (3/41, 7%), with one myocutaneous VL flap failing because of recurrent venous thrombosis during the salvage procedure. Total flap necrosis was seen in two cases (5%; VL flap: n = 1; cVLALT flap: n = 1), and partial flap necrosis in one VL flap (1/25, 4%) and in the distal ALT portion of three cVLALT flaps (3/14, 21%). No significant difference was seen between isolated VL and conjoined VL flaps regarding the partial (p = .28) or total flap necrosis rate (p = .9). CONCLUSION: The free (conjoined) VL flap provides reliable outcomes for obliterating dead space achieving durable reconstruction of complex chest wall defects.

Survival and infection rates of microvascular free flaps in pediatric mandibular reconstruction: A systematic review and meta-analysis.

BACKGROUND: Vascularized free tissue transfer has been established as an effective method in the reconstruction of mandibular defects. However, a limited understanding of its efficacy in pediatric patients persists due to its infrequent presentation. The aim of this study is to systematically consolidate the survival and infection rates of free flaps in pediatric mandibular reconstruction. METHODS: A systematic literature search was conducted on Ovid Medline, Embase, and Cochrane Library for studies published up to January 2024. We included peer-reviewed studies reporting on survival and infection outcomes associated with free flap mandibular reconstruction in pediatric patients (<18 years). We performed a random-effects meta-analysis with the inverse-variance weighted approach to estimate survival and infection rates. Heterogeneity was assessed by I2, and publication bias was examined using Egger's test. RESULTS: A total of 26 studies, reporting on 463 free flaps and 439 pediatric patients with a mean age of 10.7 years, were included in our study. Most free flaps originated from the fibula (n = 392/463, 84.7%) and benign tumors were the most common cause for mandibular reconstruction (n = 179/463, 38.7%). The pooled estimate for survival of flaps was 96% (95% CI: 93-97, I2 = 0%), and recipient-site infections were estimated to occur in 9% (95% CI: 6-13, I2 = 0%) of cases. The most common reported complications within the study timeframe were early malocclusion (n = 28/123, 21.4%) and bite abnormalities (18/131, 13.7%). CONCLUSION: Free tissue transfer for mandibular reconstruction in pediatric patients is effective and safe. Further research is required to explore functionality following mandibular reconstruction in diverse pediatric populations.

The robotic-assisted free jejunal flap for neovaginal canal creation in gender-affirming vaginoplasties.

INTRODUCTION: One of the biggest challenges with gender-affirming vaginoplasty was the creation of a long-lasting, durable, patent, and self-lubricating neovaginal canal that allowed for spontaneous, pain-free sexual intercourse. The jejunum was a durable, physiologic, and intestinal option to create the neovaginal canal that minimizes the adverse effects of skin graft, peritoneal, and colonic vaginoplasties. Free jejunal vaginoplasties had been performed in cis females for congenital genitourinary anomalies like Mullerian agenesis or after gynecologic-oncologic surgery but had yet to be reported for gender-affirming vaginoplasties. The purpose of this report was to present a technique for a physiologic, intestinal, gender-affirming vaginoplasty without the disadvantages of colonic vaginoplasties. PATIENTS AND METHODS: This report presented six patients, all natal males who identified as female, undergoing robotic-assisted free jejunal flap gender-affirming vaginoplasty. Mean age was 35.8 years (range: 21-66). Mean body mass index was 33.2 kg/m2 (range: 28.0-41.0). The proximal aspect of the neovaginal canal was created intra-abdominally by elevating peritoneal flaps from the posterior bladder wall to be reflected downward into the external neovaginal canal. The jejunal flap was harvested. The greater saphenous vein was harvested to create an arteriovenous loop between the flap vessels and the recipient femoral artery in an end-to-side fashion and a branch of the femoral vein. The jejunal flap was passed intra-abdominally through the groin incision and then trans-peritoneally into the neovaginal canal. The jejunal segment was inset to the proximal peritoneal flaps and the distal inverted penoscrotal skin of the neovaginal introitus. RESULTS: Mean length of the harvest jejunal segment was 19.2 cm (range: 15-20). Mean time to ambulation, foley removal, and first vaginal dilation were 3.3 (range: 3-4), 4.0 (range: 3-5), and 4.5 days (range: 4-6), respectively. By a mean follow-up duration of 8.0 months (range: 1-14), mean vaginal depth and diameter were 7.0 and 1.3 cm (range: 1.0-1.5), respectively. Two (33.3%) patients experienced postoperative complications, including groin hematoma (n = 1, 16.7%) and reoperation for correction of dehiscence of the jejunal flap to the vaginal introitus (n = 1, 16.7%). CONCLUSION: Gender-affirming surgeons should consider a free vascularized segment of jejunum as an option to line the neovaginal canal in the correct patients.

Reconstruction techniques using free jejunal transfer for total pharyngolaryngectomy with total glossectomy.

BACKGROUND: 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.

The versatility of the scapular free flap: A workhorse flap? A systematic review and meta-analysis.

BACKGROUND: The scapular free flap (SFF) is essential in complex reconstructive surgery and often indicated in complex defects with compromised or poor local tissue integrity. This review aims to assess the versatility and reliability of the SFF during reconstruction. METHODS: A comprehensive literature review of multiple databases was conducted following the PRISMA guidelines. An analysis of pooled data was performed to evaluate flap failure rate for any anatomical unit using SFF as the primary endpoints. Secondary endpoints included other complication rates after reconstruction such as partial flap loss, revision surgery, fistula, hematoma, and infection. RESULTS: A total of 110 articles were included, with 1447 pooled flaps. The main recipient site was the head and neck region (89.0%). Major indications for reconstruction were malignancy (55.3%), burns (19.2%), and trauma (9.3%). The most common types of flaps were osteocutaneous (23.3%), cutaneous (22.6%), and chimeric (18.0%). The pooled flap failure rate was 2% (95%CI: 1%-4%). No significant heterogeneity was present across studies (Q statistic 20.2, p = .69; I2 .00%, p = .685). Nonscapular supplementary flaps and grafts were required in 61 cases. The average length and surface area of bone flaps were 7.2 cm and 24.8cm2, respectively. The average skin paddle area was 134.2cm2. CONCLUSION: The SFF is a useful adjunct in the reconstructive surgeon's armamentarium as evidence by its intrinsic versatility and diverse clinical indications. Our data suggest a low failure rate in multicomponent defect reconstruction, especially in head and neck surgery. SFFs enable incorporation of multiple tissue types and customizable dimensions-both for vascularized bone and cutaneous skin-augmenting its value in the microsurgeon's repertoire as a chimeric flap. Further research is necessary to overcome the conventional barriers to SFF utilization and to better comprehend the specific scenarios in which the SFF can serve as the preferred alternative workhorse flap.

Application of Free Flaps in Reconstruction of Head and Neck Soft Tissue Defects With Bone Exposure.

BACKGROUND: Reconstruction of head and neck soft tissue defects with bone exposure is both challenging and technically demanding for plastic surgeon. Objectives in head and neck soft tissue defects with bone exposure reconstruction are consistent restoration of functionality while also improving appearance. This study retrospectively analyzed the results of head and neck reconstructions using various types of free flaps over the past 4 years. METHODS: A retrospective analysis was conducted from June 2019 to June 2023 on 12 patients treated at our hospital for head and neck soft tissue defects with bone exposure due to various causes. These included 4 cases of trauma from car accidents, 1 burn case, and 7 postoperative malignant tumor removals. The defect sizes ranged from 4 × 6 to 15 × 45 cm. Different free flaps were used for repair based on the defect, including 6 anterolateral thigh flaps, 3 forearm flaps, 2 latissimus dorsi flaps, and 1 dorsalis pedis flap. Flaps were designed and harvested to match the defect size and transplanted via anastomosed vessels. RESULTS: All 12 flaps survived successfully. One patient required flap thinning surgery postoperatively. All patients were followed up for over 3 months, showing good color and texture of the transplanted flaps, satisfactory healing, and significant aesthetic improvement. Donor sites showed significant scarring without functional impairment. CONCLUSION: Free flap repair for head and neck soft tissue defects with bone exposure is feasible and yields good results.

"Ice cream cone" design of forearm free flap for orbital exenteration reconstruction.

BACKGROUNDS: Reconstruction post-orbital exenteration serves the dual purpose of expediting healing, laying the groundwork for cosmetic restoration, and minimising complications such as orbitosinusal fistulae. The aim of this study was to introduce a modified "Ice cream cone" (ICC) design of the Radial Forearm Free Flap (RFFF) technique used for reconstruction of orbital exenteration cavity, along with the oncological, functional, and aesthetic outcomes. METHODS: The authors conducted a retrospective study between January 2005 and December 2020. Inclusion criteria encompassed patients treated for orbitosinusal malignancies undergoing exenteration with subsequent ICC design of RFFF reconstruction. RESULTS: Twenty-two patients underwent exenteration with the ICC design of RFFF. At the follow-up conclusion, 65% of patients regularly used orbital prosthesis. The average waiting time until the prosthesis was 10 months. Quality of life questionnaires yielded average RFFF POSAS scores of 23.5 (SD 13,6), cervical POSAS scores of 8 (SD 13,2), and orbital cavity rehabilitation scores of 5.9 (SD: 3,32). CONCLUSIONS: ICC design of RFFF is a reliable technique. It can be proposed in cases of extended exenteration with a high risk of cerebrospinal fluid (CSF) but more generally in cases of total exenteration. This technique facilitates optimal postoperative wound healing and accommodates early radiotherapy. Importantly, the bowl-shaped aspect of the orbital socket supports effective prosthetic rehabilitation for patients opting for orbital prosthesis post-surgery.

Comparison of limb reconstruction with vascularized fibula flap versus induced membrane technique in 54 pediatric cases over 16 years.

BACKGROUND: Children's bone loss of limbs represents a significant challenge for surgeons, especially given that children are growing individuals. In the pediatric population, we compared bone reconstruction using vascularized fibula flaps with the induced membrane technique. The primary purpose of this study was to evaluate the delay and quality of consolidation. METHODS: Data from patients who underwent limb reconstruction using either the fibula flap or the induced membrane were retrospectively collected from files across two centers. Perioperative and long-term complications were documented, along with functional and aesthetic outcome. RESULTS: Between 2004 and 2020, 31 children underwent limb reconstruction using a fibula flap, and 13 patients were treated using the induced membrane technique. The etiologies included 76% tumors, 20% congenital pseudarthroses, and 3.7% infections. The median size of the bone resection was 12.5 cm (range: 1.8 to 31 cm). The median time to consolidation after free fibula flap transfer was 10 months (range: 2 to 55 months) versus 7.5 months (range: 1 to 64 months) for the Masquelet technique (p = 0.54). Limb length inequality occurred in 52% of fibula cases and 39% of the induced membrane cases (p = 0.55). CONCLUSIONS: Both of free fibula flap and the induced membrane technique are effective options for bone reconstructing long bones in children. These techniques yield good functional outcomes and have comparable consolidation times.

Free fibula flap to achieve bone union after congenital pseudoarthrosis of the forearm in neurofibromatosis: Technical report based on 3 cases, and literature review.

Congenital pseudarthrosis of the forearm bones (CPFBs) is rare, with only 106 reported cases, and is frequently associated with neurofibromatosis (NF). Approximately 5% of patients with NF develop pseudarthrosis, and 50% of patients with pseudarthrosis have NF. Achieving bone union is difficult in congenital pseudarthrosis. Many methods have been attempted, including casting, internal fixation with or without grafting, and electrical stimulation, but failure is frequent. Free vascularized fibular flaps (FVFs) have been used to bridge long bone defects since 1975 and in tibial pseudarthrosis since 1979. In CPFB, FVF is more successful than other methods in achieving union and is the current treatment of choice. Here, we presented three cases of forearm pseudarthrosis treated with FVF, reviewed the literature on CPFB, and discussed some technical aspects of FVF treatment. Three cases of congenital pseudoarthrosis were treated with free fibula flaps, diagnosed at ages of 7 years (ulna), 15 months (radius), and 9 years (radius and ulna). Two flaps were stabilized with intramedullary wires and latterly, one with compression plates. One persistent nonunion received revision nonvascularized bone grafting and plating. All patients achieved union by 11 months after index surgery. Reconstruction with vascularized fibula is the treatment of choice because it offers the highest published union rates and good functional results. Complete resection of the affected bone and stable fixation, latterly with compression plates are critical to success. Surgery is technically demanding, and complications are common. Secondary surgery may be required, but outcomes are favorable. LEVEL OF EVIDENCE: IV.
