RESUMO
Objective:To investigate the clinical effect of a segmented perforator flap of free peroneal artery to repair a complex defect after oral cancer. Methods:Forty-eight patients with oral cancer admitted to the Department of Oral and Maxillofacial Surgery of the First Affiliated Hospital of Bengbu Medical College from January 2018 to January 2022, including 8 of buccal cancer, 7 of floor cancer, 14 of tongue cancer, 5 of retromolar cancet, 9 of maxillary gingival cancer and 5 of mandibular gingival cancer. After lesion resection, 24 patients in the experimental group used the partial perforator flap to repair the defect, and 24 patients in the control group used the single flap to repair the defect. Compared with the general data of the two groups, the difference was not statistically significantï¼P>0.05ï¼, which was comparable. The flap cutting range of the experimental group was 38.5-74.5 cm², and tension-reduced suture for the donor area. In the control group, the myocutaneous flap incision range was 61.0-76.5 cm², and skin graft suture for the donor area. Flap survival and patient survival were recorded and compared. The patients were followed up at 6 and 12 months after surgery, and their swallowing function and speech function, including the drinking water test, functional oral food intake scale and the Chinese language clarity test word table, were evaluated respectively, and their subjective satisfaction with the repair appearance was recorded. Patients in both groups were followed up for 12 to 60 months. Kaplan-Meier method was used to calculate the cumulative survival rate of patients, and survival curves were plotted. log-rank test was used to compare the survival curves between groups. Results:The survival rate of the two groups was 100%. The 5-year survival rate was 62.5% in the experimental group and 54.2% in the control group. There was no significant difference between the two groups ï¼P>0.05ï¼. According to the results of the functional recovery evaluation, the groups in swallowing and speech function and subjective satisfactionï¼P>0.05ï¼, and at 12 months after surgeryï¼P<0.05ï¼. Conclusion:The segmented perforator flap of free peroneal artery is flexible and can repair different anatomical structures of postoperative composite defect of oral cancer, which can effectively improve postoperative functional recovery and patient satisfaction. Therefore, the peroneal artery segmented perforator flap is the ideal flap for reconstructing postoperative composite defect of oral cancer.

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.

OBJECTIVE: To evaluate the dimensional changes in free gingival grafts (FGG) at implant sites in mandibular reconstruction patients. METHODS: Patients who received FGG 4 months after implant placement in the reconstructed mandible with no keratinized mucosa (KM) present were invited for re-examination after 36.7 ± 16.8 months (3.06 ± 1.4 years). Immediately after graft extraction (T0), graft width (GW), graft length (GL), graft thickness (GT), graft dimension (GD), and vertical bone height were documented. Re-examination (T1) included clinical examinations (GW, GL, GD, peri-implant probing depths, and modified Sulcus Bleeding Index), radiographic examination (marginal bone level), and medical chart review. RESULTS: Twenty patients and 62 implants (47 in fibula flaps and 15 in iliac flaps) were included. A significant decrease in GW (51.8%), GL (19.2%), and GD (60.2%), were found between T0 and T1 (p < .001). The univariate analysis showed that GW change was not significantly associated with reconstruction technique, baseline GL, baseline GT, baseline GD, implant location, or type of prosthesis. Implant survival rate of 100% was observed at follow-up. CONCLUSIONS: Within the limitations of the study, free gingival grafts at implant sites in the reconstructed mandible undergo dimensional change that result in a reduction of approximately 60% of the original graft dimension. Graft width decreased over 50%. CLINICAL RELEVANCE: FGG is the standard of care intervention for increasing the amount of KM around implants. This study was the first to evaluate the dimensional change in FGG at implant sites in mandibular reconstruction patients after a medium-term follow-up. CLINICAL TRIAL REGISTRATION: Clinical trial registration is not applicable as this study comprehends a retrospective analysis.

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.

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.

OBJECTIVES: This study aimed to compare the risk of osteoradionecrosis and implant survival in oral cancer patients undergoing immediate dental implants during jaw reconstruction, termed "Jaw in a Day" (JIAD), with those receiving no implants or delayed implants (non-JIAD). PATIENTS & METHODS: Clinicopathologic data were collected from prospectively enrolled JIAD patients (n = 10, 29 implants) and retrospectively from non-JIAD patients (n = 117, 86 implants). Survival analyses were performed to assess implant survival and osteoradionecrosis-free survival. RESULTS: Osteoradionecrosis occurred in 0 % of JIAD cases compared to 19.3 % in non-JIAD cases without implants and 71.4 % in non-JIAD cases with delayed implants (p = 0.008). Osteoradionecrosis-free survival was significantly better in the JIAD group than the non-JIAD group (p = 0.0059). Implants in the JIAD group all survived regardless of radiation therapy (29/29, 100 %) and 95.1 % (58/61) of implants survived in delayed implants in non-irradiated fibula without radiotherapy. Meanwhile, only 11 of 25 implants placed in irradiated fibula flaps survived, even when the implants were placed after a median time interval of 624 days after radiotherapy, and none of them were earlier than 360 days. The survival analysis revealed a significant difference (p < 0.0001). CONCLUSION: JIAD appears to offer superior outcomes in terms of implant survival and osteoradionecrosis prevention compared to delayed implant placement. Placing implants in irradiated fibula, even after years, significantly poses high risk of implant failure and osteoradionecrosis. JIAD represents a promising approach for optimal rehabilitation, particularly in oral cancer patients requiring postoperative radiotherapy. Proper positioning and orientation of implants and flaps are crucial for implant survival.

Recent studies on fibular osteotomy for varus gonarthrosis and possible subsequent biomechanical changes have attracted increasing attention to the topic. Existing studies have focused mainly on proximal fibular osteotomy with short follow-up periods. The aim of this study was to investigate changes in the alignment of the coronal plane of the ankle and knee joints in patients who underwent vascularized fibula graft harvest (VFGH). The evaluation was based on functional outcomes and radiological measurements.In the comparison between the VFGH side and the contralateral side, no significant differences in the knee inclination (KI) or talar inclination (TI) angle, knee medial clear space (K-MCS) or ankle medial clear space (A-MCS) distance were noted. However, a significant difference in the hip knee (HKA) angle was observed between the operated and nonoperated sides (0.3° ± 1.8° and 1.5° ± 1.9°, respectively [p = 0.019]). Statistically significant differences in both the knee society score (KSS) and the AOFAS scores were found between the ipsilateral donor limb and the contralateral healthy limb. Although the contralateral healthy side had better clinical scores than the VFGH side, the outcomes of the VFGH side were still satisfactory or excellent.

Distal humerus intra-articular comminuted open fracture is a challenging injury, with nonunion, infection and stiffness considered as major concerns. We report a 58-year-old woman who was admitted to the emergency department from a car accident, sustaining an open wound with severe comminution of distal humerus and complete articular fracture, classified as AO/OTA 13C2 and Gustillo Anderson type IIIA. Debridement and external fixation was done first, followed by open reduction and internal fixation with fibular strut allograft. The patient showed excellent results in radiological and functional outcomes. Level of Evidence: Level V (Therapeutic).

BACKGROUND: This work aimed to investigate the change in fingerprint depth and the recovery rule of fingerprint biological recognition function after repairing finger abdominal defects and rebuilding fingerprint with a free flap. METHOD: From April 2018 to March 2023, we collected a total of 43 cases of repairing finger pulp defects using the free flap of the fibular side of the great toe with the digital nerve. After surgery, irregular follow-up visits were conducted to observe fingerprint clarity, perform the ninhydrin test or detect visible sweating with the naked eye. We recorded fingerprint clarity, nail shape, two-point discrimination, cold perception, warm perception and fingerprint recognition using smartphones. The reconstruction process of the repaired finger was recorded to understand the changes in various observation indicators and their relationship with the depth of the fingerprint. The correlation between fingerprint depth and neural repair was determined, and the process of fingerprint biological recognition function repair was elucidated. RESULT: All flaps survived, and we observed various manifestations in different stages of nerve recovery. The reconstructed fingerprint had a clear fuzzy process, and the depth changes of the fingerprint were consistent with the changes in the biological recognition function curve. CONCLUSION: The free flap with the digital nerve is used to repair finger pulp defects. The reconstructed fingerprint has a biological recognition function, and the depth of the fingerprint is correlated with the process of nerve repair. The fingerprint morphology has a dynamic recovery process, and it can reach a stable state after 6-8 months.

A calcifying epithelial odontogenic tumor is a rare, benign odontogenic neoplasm. Surgical treatment is the option, and late recurrence is very rare. Radiologically, the lesions are commonly present scattered calcifications. This case report details a 64-year-old female patient with a recurrence of a right mandibular calcifying epithelial odontogenic tumor 2 decades after successful initial surgical removal. A segmental mandibulectomy and immediate reconstruction were performed using a planned vascularized free fibula flap with virtual surgery, custom reconstruction plate, and intraoperative computed tomography. Modifications were made to the design of the reconstruction plate to improve the cervicofacial profile and subsequent rehabilitation with dental implants. Fully guided implant surgery with point-of-care manufacturing protocol was done to improve prosthetically driven implant planning. The case presented highlights the usefulness of new technologies for mandibular reconstruction with the free fibula flap and the concept of point-of-care with technical notes that increase precision and reduce morbidity in implant-supported rehabilitation.

BACKGROUND: The long-term outcomes in pediatric patients with various extents of mandible defects have not been well-documented. METHODS: A retrospective case series in which this study looked at pediatric patients under the age of 13 who had mandibular reconstruction with free fibular flap and had not received another operation in the previous 6 months. The eating, swallowing, speech function, and quality of life are evaluated with EORTC QLQ-H&N35 after the mandible growth spurt has occurred. RESULTS: A total of 7 patients were included in this study with operation ages ranging from 6 years 1 month to 12 years 2 months. The etiology of malignant tumors was found in 2 patients and benign tumors in 5 patients. The mandibular defect distribution consists of 1 class Ic, 1 class II, 2 class IIc, 2 class III, and 1 class IVc. All patients reported no swallowing or speech difficulties. However, transient eating trouble was seen in 1 patient due to the extensive defect size that causes tooth loss. Only 1 patient received dental rehabilitation. The patients displayed an overall good quality of life with an average score of 2.857. CONCLUSIONS: Free fibular flap for mandibular reconstruction in children who have not reached their mandibular growth peak have a satisfying outcome, both in their function and quality of life.

BACKGROUND: Different fibula osteocutaneous free flap (FOCFF) configurations have been described with a double-skin paddle (DSP) to address composite through-and-through oromandibular defects: division of the skin paddle using different perforators (div-FOCFF) or a de-epithelialized DSP FOCFF (deEpi-FOCFF). This study aimed to compare the surgical outcomes using these two methods (deEpi-FOCFF/div-FOCFF). METHODS: Patients who underwent segmental mandibulectomy and reconstruction with a DSP FOCFF between 2011 and 2014 were included. We compared postoperative outcomes of patients undergoing reconstruction with deEpi-FOCFF versus div-FOCFF implementing propensity score matching. RESULTS: Of the 245 patients, 156 cases (78 pairs) were 1:1 matched. Demographic and oncologic variables were comparable between groups. The average age was 57.68 years. A higher number of perforators per flap was evident in the div-FOCFF group (p < 0.001). The deEpi-FOCFF group exhibited a higher total flap loss rate when compared to the div-FOCFF group (15 % versus 5 % p = 0.03). On multivariate analysis, number of perforators per flap (OR 0.31, p = 0.02), using the deEpi-FOCFF (OR 3.88, p = 0.03), and an increased reconstructive time (OR 1.01, p = 0.01) independently affected the likelihood of free flap failure. CONCLUSION: If the number and location of perforators are optimal, div-FOCFF improves reconstructive outcomes for composite oromandibular defects versus the deEpi-FOCFF.

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.

CASE: We describe 2 case studies, involving a 10-year-old girl with an aneurysmal bone cyst and a 12-year-old adolescent boy with Ewing sarcoma. The patient with Ewing sarcoma was previously managed with wide surgical excision and fibular graft reconstruction and subsequently experienced significant graft resorption, hardware failure, and fracture 24 months after operation. A revision limb salvage attempt was undertaken. In both cases, fibular strut grafts were harvested and fixed with intramedullary k-wires to recreate the medial and lateral columns of the distal humeral triangle. CONCLUSION: The technique achieved complete osseous integration, structural support, and functional restoration of the elbow in both cases, with good functional outcomes.

Fibula osteoseptocutaneous flap has been widely used for oncologic bony reconstruction of both the mandible and maxilla. Early and late morbidities of the donor side such as leg weakness, ankle instability, limited ankle mobility, tibial stress fractures or incision area pain are well documented; however, there is a lack of information about the effects of fibula grafting on patient quality of life. To address this issue, a scoping literature search in the PubMed electronic database was performed to identify all relevant studies and reviews in the period between 2010 and 2022. The potential discomforts after free fibula grafting and their impact on different domains of everyday living were identified and evaluated. The present literature review indicates that donor site morbidity can negatively impact patients' quality of life, albeit generally classified as minor. However, the functional and aesthetic benefits of oromandibular reconstruction clearly outweigh the associated sequelae. Nevertheless, the authors of this review highlight the importance of a comprehensive clinical evaluation of the donor site besides the recipient site during follow-up examinations. This would help to subjectively evaluate the functional and esthetical limitations of a patient's site and promptly detect morbidities that could lead to long-term complications.

BACKGROUND: The induced membrane technique is now widely used for pediatric diaphyseal bone loss due to various etiologies. Although consolidation rates remain satisfactory, complications, and healing delays may occur requiring additional procedures. We studied a series of induced membrane bone reconstructions in which the second stage included an embedded endomembranous non vascularized fibular shaft, in addition to iliac bone grafts. The purpose of this study was to analyze the results in terms of bone consolidation and complications. METHODS: This is a retrospective comparative and multicentric study of 32 children with large bone loss treated with the induced membrane reconstruction technique. Patients were divided into 2 groups according to the graft used during the second stage. The first group (G1) of 16 patients had a nonvascularized fibula embedded inside the membrane in addition with the corticocancellous grafts from the iliac crest. The second group (G2) of 16 patients underwent reconstruction using the original technique, with iliac crest graft only. RESULTS: The 2 groups were similar in terms of etiologies of bone loss and follow-up (mean: 44 mo for G1 and 49 mo for G2). Mean bone losses were 15.4 cm (range: 2 to 25; SD: 5.6) for G1 and 10.6 cm (range: 3 to 19; SD: 5.2) for G2. In the first group, all patients healed primarily, with a mean time of 5.9 months (range: 4 to 8; SD: 1.6). In the second group, 2 of 16 patients did not healed; for the others 14, healing mean time was 6.9 months (range: 3 to 12; SD: 2.7). The short-term and long-term complications rates were 38% to 19% for G1 and 50% to 31% for G2, respectively. Regarding the donor site, the fibulas reconstructed spontaneously with a mean time of 4.8 months (range: 3 to 6; SD: 1.2). CONCLUSIONS: The integration of a nonvascularized fibula during the second stage of the induced membrane technique appears to improve the consolidation rate in the pediatric population. LEVEL OF EVIDENCE: Level III-Retrospective comparative study.

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.
