Simultaneous reconstruction of tibial osteomyelitis-complicated soft tissue defects using free flap transplantation in conjunction with the masquelet technique: a retrospective study

ObjectiveTo investigate the clinical effect of anterolateral femoral free flap combined with Masquelet technique in the treatment of tibial osteomyelitis with wound surface.MethodsA retrospective study was conducted to analyze the clinical data of 25 patients with tibial osteomyelitis combined with defected wounds in Xijing Hospital of Fourth Military Medical University from Jun 2017 to Oct 2021. After one-stage treatment with free flap combined with Masquelet technique, the infection index, lower extremity function score (LEFS), and Mazur ankle function score were compared before bone defect repair and at the last follow-up.ResultsThe anterolateral femoral free flaps of 25 patients in phase I survived. The healing time of bone fracture after stage II operation was 8–12 months [(7.2 ± 0.9) months]. At the last follow-up, the infection index was significantly lower than that before bone defect repair (P < 0.01). The LEFS and Mazur ankle function scores [(56.2 ± 7.9) and (78.2 ± 16.1)] of the affected limb were significantly higher than those before bone defect repair [(26.0 ± 8.6) and (44.7 ± 18.2)] (P < 0.01). Wounds of all patients’ legs healed well, without complications (foot drop, joint dysfunction, or deformity in the affected limbs).ConclusionThe anterolateral femoral free flap combined with Masquelet technique is an effective treatment strategy for tibial osteomyelitis combined with soft tissue defects. This technology can effectively repair limb trauma, inhibit infection, and improve flexion and extension functions of knee and ankle joint.

Challenges in Radial Forearm Free Flap Surgery: A Comprehensive Case Analysis of Septic Complications at the Donor Site.

The radial forearm free flap (RFFF) has emerged as a leading option for microvascular reconstruction of head and neck soft-tissue defects. Despite the favorable outcomes conferred by RFFFs, complications such as skin graft loss and tendon exposure can occur. We present the case of a 77-year-old man who underwent RFFF reconstruction after excision of squamous cell carcinoma from the head and neck. The patient subsequently developed flexor tenosynovitis, septic arthritis of the wrist, and osteomyelitis of several carpal bones as a direct result of partial skin graft loss and prolonged tendon exposure at the donor site. To the best of our knowledge, this is the first reported case of this specific complication. Review of the literature reveals the need for continued research into RFFF donor site complications to mitigate the incidence of significant morbidity.

Lateral Calcaneal Artery Perforator/Propeller Flap in the Reconstruction of Posterior Heel Soft Tissue Defects

Abstract Introduction Posterior heel soft tissue defects with/without tendoachilles injury are difficult to reconstruct because of bony prominence, limited expendable local soft tissues, and significant donor site morbidity. In this study, we evaluate the lateral calcaneal artery (LCA) perforator/propeller flap for posterior heel soft tissue defect reconstruction. Materials and Methods A preliminary cadaveric study was done on 22 specimens to study the course of the LCA and its perforators. The knowledge gleaned from the cadaveric study was applied in our clinical study. The clinical study was conducted from January 2018 to May 2023 in 13 patients (10 males and 3 females) with posterior heel defects. The primary movement of the perforator flaps were either V-Y advancement (n = 10) or propeller (n = 3). Results All the flaps settled well except for superficial epidermolysis in one patient (7.69%) which healed conservatively. The average follow-up period was 14.53 months. Postoperatively, all patients had normal gait and normal range of movements. The LCA with the maximum number of perforators in the retrofibular/retromalleolar segment and the islanded flaps based on these perforators provided the excellent coverage for tendoachilles insertion defects and posterior heel defects facilitating excellent shoeability in all cases. Conclusion The study concludes that the LCA perforator/propeller flap may be a reliable cover for the posterior heel defects with good color, texture, thickness, and contour match rendering a shoeable stable foot.

Application of Modified Skin Stretching for Soft Tissue Defect Reconstruction in the Ankle and Foot: A Retrospective Report.

The failure rate of foot and ankle soft tissue defect reconstruction with flap is relatively high, often posing a significant burden on patients. The aim of this study is to explore the effectiveness of repeated stretch sutures in repairing skin and soft tissue defects of the ankle and foot. Twenty-three patients with ankle and foot skin and soft tissue defects were retrospectively analyzed between February 2016 and February 2019. Sutures were repeatedly stretched every 3-5 days. Local skin grafting was performed if necessary after wound surfaces disappeared or exposed tendons and bones were covered by soft tissue. Wound healing time, postoperative healing area, Vancouver Scar Assessment Scale, sensation, and function of the new skin were evaluated. Healing time was 17-35 (24.43 ± 5.29) days. Ten patients wholly healed, and 13 healed by approximately 70.08% ± 6.59%. The Vancouver Scar Assessment Scale average score was 2.83 ± 1.19 points, of which 15 cases were excellent (0-3 points) and 8 cases were good (4-7 points). The sensation and function of the new skin after repair were equivalent to those of normal skin after the last follow-up. Applying repeated tension sutures on the skin and soft defects of the ankle and foot reduced the skin graft area and decreased complex high-risk surgical flaps' use and transplantation area.

Comparison of the efficacy of medial tarsal venous flaps and traditional venous/arterial free flaps in the reconstruction of hand soft tissue defects: A new type of physiological flap.

The treatment of hand soft tissue defects primarily relies on flap reconstruction. However, traditional venous/arterial free flaps have several disadvantages, including damage to the donor site, bruising, discoloration, blister formation, and even necrosis. These issues can significantly impact patient recovery and outcomes. Therefore, there is a need for alternative approaches that minimize these complications and improve overall patient care. To compare the efficacy of medial tarsal venous flaps and traditional venous/arterial free flaps in the reconstruction of hand soft tissue defects, evaluating various clinical outcomes and patient recovery metrics. We screened 30 suitable patients with hand soft tissue defects and randomly assigned them to three groups. Patients in each group were transplanted with either medial tarsal free venous flaps or traditional arterial/venous free flaps to achieve coverage and reconstruction of the soft tissue defects. The results were compared and analyzed using the following metrics: operation time, survival rate, complication rate, pain index, postoperative infection rate, and functional evaluations of both the donor and recipient areas. There was no significant difference in operation time between the medial tarsal free venous flaps and the traditional forearm free venous flaps. The operative time for both types of flaps was shorter than that of the traditional free fibular flap from the hallux. The survival rate of the medial tarsal free venous flaps was comparable to that of the fibular free arterial flaps from the great toes and significantly higher than that of the traditional forearm free venous flaps. The complication rate showed an inverse trend to the survival rate of the flaps. In terms of pain, the pain index for the medial tarsal free venous flaps was significantly lower than that of the fibular free arterial flaps from the hallux and comparable to that of the forearm free venous flaps. Regarding postoperative infection rates, the forearm free venous flap had the highest rate, while there was no significant difference between the medial tarsal free venous flaps and the fibular free arterial flaps from the great toes. The functional recovery of the medial tarsal free venous flaps was good in both the donor and recipient areas. There was no poor functional performance in the donor areas of the fibular free arterial flaps from the hallux or the recipient areas of the forearm free venous flaps. The medial tarsal free venous flaps effectively avoid the disadvantages of traditional venous and arterial free flaps, combining their advantages. These flaps offer shorter operative times, higher survival rates, and lower pain indices. They also provide excellent functional recovery in both donor and recipient areas. Thus, medial tarsal free venous flaps represent an ideal solution for reconstructing hand soft tissue defects.

Indications, Postoperative Outcomes, and Complications of the Lateral Arm Free Flap: A Systematic Review and Meta-analysis

Background: The lateral arm free flap (LA-FF) has become an increasingly popular choice in the reconstruction of soft tissue defect in many anatomical regions. However, there is a paucity of literature regarding its safety and efficacy. The aim of this study is to analyze its different applications along with their surgical outcomes. Methods: A systematic review including all studies assessing the surgical outcomes of the LA-FF and proportional meta-analysis using a random-effect DerSimonian–Laird model was performed to assess the postsurgical complications and flap failures. Results: Twenty-five articles were included in the final analysis, representing a total of 1272 flaps in 1256 patients. Indications were mainly defects following tumoral resection and trauma. Across the different studies, the reported flap size range varied from 2 × 4 cm to 12 × 16 cm. The overall pooled flap failure rate across all indications was 3% [95% confidence interval (CI), 0.01–0.04], with a pooled failure rate of 2% (95% CI, 0.01–0.04) in the head and neck region, 3% (95% CI, 0.01–0.06) in the upper limb region, and 3% (95% CI, 0.01–0.06) in studies evaluating its use in different anatomical locations. The overall donor site complication rate was 11% (95% CI, 0.03–0.21), with no major complications described. Conclusions: This meta-analysis demonstrates safety and efficacy of the LA-FF in reconstructing moderate to large soft tissue defects. It is mainly used for head and neck posttumoral resection and upper and lower limb posttraumatic reconstruction.

Open segmental tibial bone defects treated with Ilizarov frame: a radiological and functional outcome study with average ten year follow-up.

Surgical reconstruction of large post-traumatic tibial bone and soft tissue defects following high-energy trauma presents a significant challenge for orthopaedic surgeons. This study aimed to evaluate the functional and radiological outcomes of large post-traumatic tibial bone and soft tissue defects managed by single or double-level bone transport using the Ilizarov technique. 13 patients who underwent treatment for large tibial bone defects (Gustillo IIIa, IIIb, IIIc) along with soft tissue defects with Ilizarov from 2010 to 2020A.D were included. ASAMI functional and radiological outcomes were assessed at the final follow-up to report the outcome. The mean age was 27.38 (18-48). An average bone defect was 7.69cm (5-13cm). Based upon the Gustillo-Anderson classification (GA), 2 (15%) of them were GA - 3A, 7 (54%) were GA - 3B, and 4 (31%) were GA - 3C. The average time of distraction was 11.76 weeks (8-16). The average time for the union was 37 weeks (27-48 weeks). The average bone lengthening was 7.69cm (5-13cm). The mean final leg length discrepancy (LLD) at the final follow-up was 1.96cm (0-4cm). The primary union was achieved in eight cases, and five required bone grafting at the docking site. Using the ASAMI (Association for the Study of the Method of Ilizarov) scoring system, the functional results were excellent in six and good in seven cases, while the bony results were excellent in eight, good in four and fair in one case. Good to excellent functional and radiological scores (ASAMI) can be expected when using the Ilizarov frame for simultaneous treatment of the large tibial bone and soft tissue defect when this method is applied with correct principles.

Trapezius Island Myocutaneous Flap for Head, Neck, and Facial Reconstruction in Neurofibromatosis Type 1-Associated Plexiform Neurofibromas.

Reconstruction of significant soft tissue defects in the head and neck region after resection of extensive plexiform neurofibromas, as well as preservation and restoration of cosmetic and functional aspects, presents a considerable challenge. The purpose is to evaluate the feasibility of eTMF in repairing substantial defects after the complete resection of NF1 PN. Patients diagnosed with substantial neurofibromatosis (NP) type 1 (NF1), according to the revised criteria, underwent complete resection and remodeling of the facial aesthetic unit. An extended vertical lower trapezius island myocutaneous flap (eTIMF) was used for the defect reconstruction. Perioperative complications were evaluated using the Clavien-Dindo classification. ECOG PS was assessed. Postoperative follow-up at 6 months and completion of UW-QOL. The questionnaire included swallowing, chewing, speech, and quality of life scores. Two patients had pathogenic missense variants: c.5609G>A (p.Arg1870Gln) in exon 38 of NF1 in the first case, and c.4600C>T (p.Arg1534*) in exon 35 in the second case. Two eTMFs were harvested successfully. Five facial esthetic units were remodeled, and 4 units were remodeled. Two extensive tumors were nearly entirely removed. No severe complications were noted. The ECOG PS improved from grade 3 in the first week postsurgery to grade 0 by the eighth week. The UW-QOL results indicated that swallowing, chewing, and speaking functions returned to their preoperative levels, with a 40% improvement in quality of life, reaching 60% and 80%, respectively. eTMF to repair substantial defects following total resection of NF1 PN and facial esthetic unit remodeling enhances appearance, function, and psychosocial outcomes. This technique is safe, efficient, resource-conserving, and simple to implement.

Investigating the Thickness of the Deltoid Free Flap Using Ultrasonography and Clinical Application in Foot and Hand Soft-Tissue Defect Reconstruction.

Although the deltoid flap is widely described as a thin flap, no studies have reported on the measurement of its thickness. Thus, this study aimed to measure deltoid flap thickness at different points using brightness-mode ultrasonography and report our initial clinical experience. This study included 36 adults (26 males and 10 females; mean age: 34 years) with 72 healthy deltoid regions. Ultrasonography was employed to measure flap thickness at eight designated positions. The ultrasonography results were also applied clinically in 30 patients to evaluate its compatibility. The mean deltoid flap thickness was 5.14 ± 0.81 mm, with the thickest point being the emerging point of the flap pedicle. The subcutaneous fat gradually thinned toward the shoulder. No significant differences in the subcutaneous fat layer thickness were observed between the right and left sides, different ages, or the two sexes. Body mass index was the most critical factor related to flap thickness (p < 0.001). All deltoid free flaps were successfully transferred, resulting in good or excellent final clinical outcomes. The ultrasonography results suggest harvesting the deltoid flap upward toward the shoulder area and across the acromion from the emerging position of the flap pedicle to optimize flap thinness. The results showed that besides the flaps that have been clinically well established, the deltoid flap should be considered a valuable alternative for reconstructing limb soft-tissue defects, particularly where thin flaps are required and favorable aesthetic results are crucial.

Utilization of facial fat grafting augmented reality guidance system in facial soft tissue defect reconstruction

BackgroundSuccessfully restoring facial contours continues to pose a significant challenge for surgeons. This study aims to utilize head-mounted display-based augmented reality (AR) navigation technology for facial soft tissue defect reconstruction and to evaluate its accuracy and effectiveness, exploring its feasibility in craniofacial surgery.MethodsHololens 2 was utilized to construct the AR guidance system for facial fat grafting. Twenty artificial cases with facial soft tissue defects were randomly assigned to Group A and Group B, undergoing filling surgeries with the AR guidance system and conventional methods, respectively. All postoperative three-dimensional models were superimposed onto virtual plans to evaluate the accuracy of the system versus conventional filling methods. Additionally, procedure completion time was recorded to assess system efficiency relative to conventional methods.ResultsThe error in facial soft tissue defect reconstruction assisted by the system in Group A was 2.09 ± 0.56 mm, significantly lower than the 3.23 ± 1.15 mm observed with conventional methods in Group B (p < 0.05). Additionally, the time required for facial defect filling reconstruction using the system in Group A was 25.45 ± 2.58 min, markedly shorter than the 37.05 ± 3.34 min needed with conventional methods in Group B (p < 0.05).ConclusionThe visual navigation offered by the fat grafting AR guidance system presents obvious advantages in facial soft tissue defect reconstruction, facilitating enhanced precision and efficiency in these filling procedures.

Surgical refinements and sensory and functional outcomes of using thinned sensate anterolateral thigh perforator flaps for foot and ankle reconstruction: A retrospective study.

To improve the use of sensate anterolateral thigh (ALT) flaps for foot and ankle reconstruction, we employed a thinned nerve-selective harvesting technique. The data of 31 patients in whom sensate ALT perforator flaps were transferred for reconstruction of soft-tissue defects in the foot and ankle were reviewed. Flaps were elevated with 2 refinements. The first is the initial selection of the "true" sensory branch in the medial incision on the suprafascial plane. The second is flap thinning by keeping a cuff of thin deep fat surrounding the point where the perforator or nerve branch inserts into the superficial fat layer. The recipient site assessment consisted of complications, monofilament touch perception, sharp-blunt discrimination, axial circumference, and American Orthopedic Foot and Ankle Society score. After a mean follow-up of 31.7 months, all flaps survived uneventfully, except for marginal necrosis in 1 patient, infection in 1 patient, ulceration in 2 patients, and secondary thinning in 3 patients. The sensation of each flap was restored. A total of 87% and 90% of the patients exhibited 5 or more positive response points in the Semmes-Weinstein monofilament touch and sharp-blunt discrimination testings, respectively. The mean axial circumference of the reconstructed foot was 27.4 cm (the unaffected side was 25.8 cm). All patients achieved mobility in ordinary shoes with a mean functional score of 74.6. The thinned nerve-selective sensate ALT perforator flap can be a favorable option for foot and ankle reconstruction. This method also offers the possibility of preserving the nerve branch at the donor thigh.

Reconstruction for extensive sacrococcygeal defects in complex tumor patients with personalized customized gluteus maximus myocutaneous flaps

AimTo evaluate the clinical effects of personalized customized gluteus maximus myocutaneous flaps (GMMF) for reconstruction of extensive sacrococcygeal soft tissue defects in complex tumor patients. MethodsA retrospective chart review was conducted on 8 patients who underwent personalized customized GMMF reconstruction for large sacrococcygeal defect from December 2021 to August 2023. The personalized customized GMMF were designed based on the variations of tissue defect in location, shape and volume of different dead spaces. The principle of the personalized GMMF is to ensure that the rotation point of the flap can reach the farthest end of the defect. Patient demographics, operative characteristics, and perioperative risk factors were analyzed. Clinical outcomes were assessed, focusing on complications such as flap necrosis, wound dehiscence, infection, seroma, and hematoma. ResultsSix patients with rectal cancer and two with sacral tumors underwent personalized customized GMMF reconstruction for extensive sacrococcygeal defects. The average volume of the wound cavity was 104 mL, with a mean vertical depth was 10.8 cm. Six patients had low serum albumin (<35 g/L). After a mean follow-up of 15.5 months, no major complications occurred, except for one seroma that resolved within 2 weeks. ConclusionThe personalized customized GMMF described in this study is an effective method for reconstructing large sacrococcygeal wounds with significant depth in complex tumor patients. It allows for greater rotation of the muscle flap into the sacrococcygeal wound defect and provides adequate blood supply by utilizing the bulk of muscle tissue to obliterate dead space.

Efficacy of superficial femoral artery as a recipient in free flap reconstruction around the knee: Four case reports and a literature review

PurposeReconstructing soft tissue defects around the knee with free flaps presents challenges in recipient vessel selection. Although the superficial femoral artery (SFA) offers exposure ease and anatomical stability, concerns arise regarding its distance from the defect site, difficulty in performing anastomosis and potential peripheral ischaemia. This study aimed to reassess the suitability of SFA as a recipient vessel for knee reconstructions by examining our cases and those from previous reports. MethodsWe reviewed four cases of knee soft tissue defects reconstructed with free flaps using the SFA, detailing surgical techniques and outcomes. Additionally, a comprehensive literature search was conducted for articles on using SFA as a recipient vessel for knee free flaps, using PubMed, Web of Science and EBSCOhost databases. ResultsIn all four cases, latissimus dorsi (LD) flaps were used, with end-to-side anastomosis performed using a large slit-shaped arteriotomy. All flaps demonstrated successful survival without complications. Our analysis included 85 cases, comprising four of our cases and 81 cases from 16 articles. Sarcoma resection was the most common aetiology, followed by total knee prosthesis-related defects, trauma and osteomyelitis. Complete flap necrosis occurred in 5% of cases. The LD flap was the predominant choice, alongside other long-pedicle flaps. The SFA provided coverage for all knee areas except the distal lateral patellar region. ConclusionDespite the limited evidence, the SFA appears to be a reliable recipient vessel for knee soft tissue reconstruction. Comprehensive understanding of the characteristics of the SFA and flaps used enhances the safety and efficacy of soft tissue defect reconstruction around the knee.

Reconstruction of Defects After Oral Cancer Surgery With the Superior Thyroid Artery Perforator Flap.

The superior thyroid artery perforator flap (STAPF) was previously presented as a type of locoregional pedicled flap for lateral facial and temple defects. In this study, we aimed to present our clinical experience with this flap for the reconstruction of soft tissue defects after oral cancer surgery. From February 2019 to December 2022, 24 patients with oral cancers at the School and Hospital of Stomatology,Peking University were included. Among these patients, 10 had cancers located in the tongue, five in the cheek inside the oral cavity, three in the lower gingiva, two in the upper gingiva, two in the floor of the mouth, and two in the palate. All patients were treated with extended tumor resection, neck dissection, and STAPFs to reconstruct the soft tissue defects. The details of the flap, including the flap size, venous flow, vascular pedicle length, the attatched muscle, and operation time were evaluated. The dimensions of the flap skin paddle ranged from 3 cm × 5 cm to 6 × 14 cm. Fourteen patients had a closely concomitant superior thyroid vein perforator. Ten patients had non-closely concomitant superior thyroid veins perforators which retrograde external jugular vein. The vascular pedicle length ranged from 5 to 9 cm. The infrahyoid muscle group or sternocleidomastoid muscle was included in the flaps in three patients. A total of 23/24 flaps were successful. The STAPF is a viable reconstructive option for patients with oral cancers. It has the advantages of being robust, being thin, short operation time, and minor donor site complications. 4 Laryngoscope, 2024.

The Impact of the Dermal Matrix in Tissue Reconstruction: A Bibliometric Perspective in Plastic Surgery.

In the vast field of medical scientific research, few topics have managed to attract as much attention and mobilise academic resources as the use of dermal matrices in the reconstruction of soft tissue defects. In this study, we used bibliographic metrics such as co-authorship, keyword co-occurrence, and citations per document to analyse the relationship between the use of dermal matrices to reconstruct soft tissue defects caused by burns, tumours, and trauma. In addition, keyword analysis has highlighted the crucial role of technology in recent studies and the innovation brought about by the use of dermal matrices in the reconstruction of soft tissue defects. Keywords used in recent studies have revealed the critical role of technology in the development of the field. We extracted a set of 1329 research papers from the Web of Science Core Collection database between 2010 and 2024 that met our criteria. Through keyword analysis, we identified technology as a significant factor in recent studies. Our results showed that there is very little collaboration between authors on the topic and that most of them are from Asia. A significant number of articles on this topic come from the USA, China, Japan, Germany, the UK, and France. We discovered the top ten most cited sources analysing the use of dermal matrices in the reconstruction of soft tissue defects. Finally, we think that this study will be beneficial for our further research.

The myocutaneous gastrocnemius flap for periprosthetic joint infection of the knee.

Periprosthetic joint infection (PJI) following total knee arthroplasty (TKA) presents significant challenges, especially in elderly and comorbid patients, often necessitating revision surgeries. We report on a series of patients with confirmed PJI of the knee and concomitant soft-tissue/extensor apparatus defects, treated by using pedicled myocutaneous medial or lateral sural artery perforator (MSAP/LSAP) gastrocnemius flaps. Our retrospective study at the Center for Musculoskeletal Infections, included patients with knee PJI undergoing pedicled myocutaneous MSAP/LSAP gastrocnemius flap reconstruction for combined soft tissue and extensor apparatus defects. The tendinous back of the gastrocnemius muscle was used and, if required, the Achilles tendon for extensor apparatus reconstruction, with the skin island addressing the cutaneous defect. Perioperative complications and postoperative outcomes after 1 year were evaluated, including functional and clinical assessments with the American Knee Society Score (AKSS). Eight patients (mean age 73 years; five female) were included, predominantly with Staphylococcus aureus infections. Six patients involved isolated MSAP flaps, two were extended with the Achilles tendon. The median time for wound healing was 9 days. Short-term follow-up showed successful reconstruction in seven patients, with minor wound dehiscence in one patient. One patient required flap revision for a perigenicular haemato-seroma and two patients were diagnosed with new haematogenous PJI infection. Significant improvement in AKSS scores after surgery was observed (functional AKSS: median 33-85; clinical AKSS: median 64-91, p = 0.001). Pedicled myocutaneous MSAP/LSAP gastrocnemius flaps offer a safe, reliable and versatile option for reconstructing combined soft tissue and extensor apparatus defects in PJI after TKA. This approach yields excellent functional outcomes with minimal peri- and postoperative complications, which is particularly beneficial in elderly and comorbid patients and feasible in settings without microsurgical availability. Level IV.

Versatility of Proximal Sural Island Sensate Fasciocutaneous Flap in Reconstruction of Soft Tissue Defects of Knee and Proximal Leg

Background: The proximal sural island sensate (PSIS) fasciocutaneous flap presents an ideal alternative in reconstruction of defects of the knee and proximal leg. It provides a thin sensate flap with good aesthetic outcomes and reduced donor site morbidity. However, only limited reports exist in the literature about this flap.Methods: This is a retrospective study done between December 2018 and December 2021 including 30 patients, among which seven cases had defects located on the knee and 23 cases in the proximal part of the leg. Mean age of the study population was 41 years. The maximum flap size was 8×12 cm, while the maximum pedicle length was 15 cm.Results: All 30 flaps survived well with only minimal complications occurring in a few patients such as epidermal loss and distal tip necrosis. No arterial or venous crisis occurred postoperatively in any case. Donor sites were managed with one-stage primary closure or split-thickness skin grafts. Functional deficits were not detected in any of the cases.Conclusion: We found the PSIS fasciocutaneous flap to be a simple and reliable technique to perform. The flap offers extensive coverage, reaching from the knee to the proximal leg, and provides thin, pliable, and sensate skin, resulting in excellent aesthetic and functional outcomes.

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

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. 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. 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. Free flap repair for head and neck soft tissue defects with bone exposure is feasible and yields good results.

Submental Flap Versus Radial Forearm Free Flap for the Reconstruction of Medium Size Soft Tissue Defect in the Oral Cavity.

The aim of this work is to compare the functional and esthetic outcome of the submental flap and radial forearm free flap for the reconstruction of medium-sized soft tissue defect in the oral cavity. Patients diagnosed with squamous cell carcinoma of the oral cavity and reconstructed with a submental flap or radial forearm free flap between 2015 and 2020 were reviewed and analyzed. Tumor site, complication at the donor site, complication at the recipient site, duration of the hospital stay, local or cervical recurrence, and esthetic results were also analyzed to compare the difference in outcomes between the two groups. Submental flap represents a safe and useful reconstructive recourse for head and neck reconstructive surgeons when it is correctly indicated. Lower rate of complication at the donor site, better esthetic result, and a shorter hospital stay represent the strengths of this flap when it is not necessary to perform compartment surgery. However, more studies are needed with a larger number of patients.

Distally based peroneus brevis flap: Reconstruction of complex soft-tissue defects with bony infection of the lateral malleolus

BackgroundManaging wounds of the lateral malleolus is challenging owing to limited nearby tissues and possibly injured or inadequate vessels for free flaps, especially in case of underlying infections. Moreover, free flaps require specialized skills and are not suitable for every patient. Therefore, identifying reliable local alternatives is crucial. This retrospective study investigated the efficacy and safety of the distally based peroneus brevis muscle flap in treating complex and infected soft-tissue defects of the lateral malleolus. Materials and methodsA retrospective medical chart review of all patients who underwent a distally based peroneus brevis muscle flap reconstruction in the context of an infected lateral malleolus defect at Geneva University Hospitals between October 2020 and January 2024 was performed. ResultsTen patients underwent lateral malleolus reconstruction using a distally based peroneus brevis muscle flap primarily to address post-traumatic infections. Flap coverage was performed within 4 weeks of infection onset for post-traumatic cases, alongside antibiotic treatment. The defects were moderate in size, with a median width of 2.5 cm and length of 5.5 cm. There were no complete or partial flap failures. All patients regained the ability to walk within 5 days after surgery. ConclusionsThe distally based peroneus brevis muscle flap was efficient in managing complex and infected soft-tissue defects of the lateral malleolus, with control of infection in all patients and minimal donor-site morbidity.
