Project description:The ideal reconstruction of lower limb defects should replace like with like and minimize morbidity to the donor site, achieving the best possible esthetic and functional outcome. The goal is to obtain stable healing and to resume daily life in an efficient manner. Although the classical local flaps such as gastrocnemius, soleus muscle flap, and the reverse sural flap have allowed to achieve those goals, perforator flaps are now added on to the armamentarium in lower extremity reconstruction using local flaps. A perforator-based local flap, such as a propeller or keystone flap, has made reconstruction efficient while further reducing donor-site morbidity. This article aims to provide a useful review of the best available local flaps for lower limb defects.

Project description:Local perforator flaps are used as immediate volume replacement techniques in breast conserving surgery. Here, we describe a case series of local perforator flaps used in the delayed setting to correct defects following previous breast surgery, including previous breast conservation surgery or mastectomy with reconstruction. All cases were performed in a tertiary referral breast unit between 2014 and 2020. Cases were identified using a prospectively maintained database. Indications, type of perforator flap used, immediate post-operative complications, and longer term outcomes were recorded. Fifteen cases were identified: 8 following previous breast conserving surgery and radiotherapy, 6 following mastectomy and reconstruction, and 1 for developmental breast asymmetry following childhood radiotherapy. Indications included volume deficit, contour defect, asymmetry, and capsular contracture. One patient a major complication requiring return to theater due to implant-related infection. There were no flap losses. Longer term, 2 patients underwent lipomodeling to further augment breast volume as part of a planned, staged revision. One patient subsequently elected to have bilateral breast implant exchange to increase volume. Our series shows the versatility of local perforator flaps in the correction of complex breast defects that can occur following previous breast surgery. Delayed local perforator flaps are associated with low morbidity, and further revision surgery is not commonly required.

Project description:Free-flap surgery and skin grafting can be used to reconstruct large facial defects that may result after skin cancer removal by Mohs micrographic surgery (MMS). However, these two methods may produce low postsurgical patient satisfaction with aesthetics, and free-flap surgery may produce an undue burden for the majority of skin cancer patients, who are of advanced age. Hence, the authors examined outcomes of large facial defect reconstruction using multiple flaps.Among patients undergoing MMS for skin cancer at Pusan National University Hospital between January 2013 and December 2015, we evaluated 7 patients (2 males, 5 females; average age, 73.14 years) treated for large facial defects from basal cell carcinoma. Based on operative and follow-up records, we investigated the number and type of flaps used, postsurgical complications, and patients' post-surgical satisfaction.Two and 3 types of flaps were used for 5 and 2 patients, respectively. Most frequently used were nasolabial flaps (7 times in 6 patients) and forehead flaps (once in each of 4 patients). The average follow-up period was 14 months, with no complications-including necrosis, hematoma, or wound dehiscence-observed. Post-surgical satisfaction averaged 4.4 out of a maximum of 5 points.Reconstruction using two or more flaps for large facial defects after skin cancer removal using MMS produced satisfactory outcomes while preventing aesthetic problems. Practitioners should consider using multiple flaps when choosing a reconstruction method for large facial defects following skin cancer removal.

Project description:The wide awake local anesthesia no tourniquet (WALANT) technique has been proven to be safe and effective for upper extremity surgery. WALANT does not require extensive medical clearance and allows for intraoperative assessment of range of motion. Additionally, it is frequently associated with lower costs and less postoperative pain when compared with traditional methods of anesthesia. Despite its expanded use for hand procedures, there are sparse data to support the use of WALANT in local and regional soft tissue flaps.MethodsA retrospective review was performed. Twenty-one patients who underwent a local or regional soft tissue flap surgery using the WALANT technique from February 2, 2018 to February 25, 2022 were included in our analysis.ResultsOverall, one Louvre flap, two posterior tibial artery perforator propeller flaps, two reverse radial forearm flaps, two Quaba flaps, six cross finger flaps, one reverse homodigital island flap, three first dorsal metacarpal artery flaps, two thenar flaps, and two Moberg flaps were performed. Patients were followed up for an average of 11.9 ± 8.1 weeks. During this time, no postoperative complications occurred. All patients demonstrated appropriate healing at donor and recipient sites. Full range of motion was regained for all patients.ConclusionsWALANT is safe and effective for use in local and regional soft tissue flap surgery. Surgeons should consider this technique for more involved procedures such as flap surgery, as preliminary results demonstrate positive outcomes and potentially superior recovery for patients.

Project description:Tumors of the skull base are rare in children, and reconstruction in such patients has rarely been reported. We reviewed 16 cases of skull base reconstruction in patients under 18 years. The study group consisted of 10 boys and 6 girls, whose ages ranged from 2 to 17 years. Of the 16 cases, eight tumors were benign and eight were malignant. Defects were anterior in six cases, lateral in eight cases, and anterolateral in two cases. Reconstruction was performed with locoregional flaps in 11 cases and with free flaps in 5 cases. No significant difference was found between locoregional flaps and free flaps in total operative time, intraoperative blood loss, or postoperative hospital stay. However, in some cases, total operative time, reconstruction time, and blood loss increased to a degree unacceptable for pediatrics. Minor complications occurred in three patients and a major complication occurred in one case. Of four patients, three patients with postoperative complications had undergone chemoradiotherapy. Because of the physical weakness of pediatric patients, complicated reconstructive procedure should be avoided. We believe locoregional flaps will become the first choice for reconstruction. However, if patients have large, complex defects and have received radiotherapy, appropriate free flaps should be used to avoid postoperative complications.

Project description:Background: Reconstruction with the use of perforator flaps makes it possible to make the skin surface resistant to the influence of mechanical factors and as similar to the lost skin cover as possible. However, while planning any flap, along with the design of the required shape and size, its blood supply should be taken into account to ensure optimal viability. Therefore, the task to precisely determine the topographic-anatomical relationships suitable for the formation of a pedicle of perforators is still relevant. The aim of this study was to increase the efficiency of surgical reconstruction of wound defects by transposition of locoregional perforator flaps. Methods: The authors conducted a retrospective analysis of 72 cases of reconstruction by means of locoregional perforator flaps with vascular pedicle detachment to determine the efficiency of preoperative diagnostic preparation with the help of multidetector-row computed tomographic angiography (MDCT) in the process of reconstruction. Thirty-seven individual cases of surgical interventions were chosen using a case-controlled study from the study group when MDCT with angiography was used for preoperative planning of perforator flaps, as well as 35 control cases similar in terms of important predictive peculiarities with the reconstruction at the same level of difficulty. The patient groups were precisely matched by gender (P = .950), age (P = .804), flap area (P = .192), and type of reconstruction that was performed. Results: In all cases, the location of the perforator with a diameter greater than 1.0 mm was marked. All perforators determined during MDCT scanning were faultlessly localized intraoperatively. The distance between the intraoperative position of the perforator and the position obtained in the result of the examination did not exceed 1 cm. There was no need to change the planned design of the flap intraoperatively. In all cases where MDCT was performed, the duration of the surgical procedure varied from 60 to 150 minutes (average: 120.77 [18.90] minutes) and was reduced by 49.40 minutes (95% CI: 39.17-59.63) compared with the patients who did not undergo preoperative visualization of perforators where the average duration of the operation was 170.17 (19.19) minutes (from 140 to 220 minutes). Among the patients examined by MDCT, surgical complications were noted in 5 cases (13.51%) compared to 14 cases (40.00%) in the control group. Conclusions: The preoperative MDCT for the locoregional perforator flap reconstruction makes it possible to increase the efficiency of patient treatment given the reduction in surgery duration by 49.40 minutes (95% CI: 39.17-59.63) on average and the reduction in the level of postsurgery complications from 40% to 13.5% compared with the group of patients in whom presurgical visualization was not performed (P = .031).

Project description:ObjectiveThe purpose of this study is to determine the correlation between non-technical risk factors and the perioperative flap survival rate and to evaluate the choice of skin flap for the reconstruction of foot and ankle.MethodsThis was a clinical retrospective study. Nine variables were identified. The Kaplan-Meier method coupled with a log-rank test and a Cox regression model was used to predict the risk factors that influence the perioperative flap survival rate. The relationship between postoperative wound infection and risk factors was also analyzed using a logistic regression model.ResultsThe overall flap survival rate was 85.42%. The necrosis rates of free flaps and pedicled flaps were 5.26% and 20.69%, respectively. According to the Cox regression model, flap type (hazard ratio [HR] = 2.592; 95% confidence interval [CI] (1.606, 4.184); P < 0.001) and postoperative wound infection (HR = 0.266; 95% CI (0.134, 0.529); P < 0.001) were found to be statistically significant risk factors associated with flap necrosis. Based on the logistic regression model, preoperative wound bed inflammation (odds ratio [OR] = 11.371,95% CI (3.117, 41.478), P < 0.001) was a statistically significant risk factor for postoperative wound infection.ConclusionFlap type and postoperative wound infection were both independent risk factors influencing the flap survival rate in the foot and ankle. However, postoperative wound infection was a risk factor for the pedicled flap but not for the free flap. Microvascular anastomosis is a major cause of free flap necrosis. To reconstruct complex or wide soft tissue defects of the foot or ankle, free flaps are safer and more reliable than pedicled flaps and should thus be the primary choice.

Project description:PurposeFunctional reconstruction of mutilating hand injuries poses a challenge to the surgeon. We present our experience with use of multiple composite tissue flaps transplant for functional reconstruction of hand in patients with mutilating hand injuries. The associated merits and demerits of these surgical approaches are briefly discussed.MethodsFrom August 2004 to October 2014, functional reconstruction of hand with transplantation of multiple composite tissue flaps was performed in 8 patients. These included the toe with dorsal pedis artery flap, the reverse posterior interosseous artery flap, and the anterolateral thigh flap. Mean interval from injury to functional reconstruction was 10.6 days.ResultsAll transplanted skin flaps and reconstructed neofingers survived completely. Only 1 patient developed wound infection at the recipient site (hand), which resolved without any debridement or revision surgery. At the donor site (foot), partial skin necrosis was observed in 1 patient, which healed with local wound care. In other patients, all wounds healed without any complications. The average range of movement at the neofinger metacarpophalangeal and interphalangeal joints was 38° and 73°, respectively. None of the patients required revision surgery.ConclusionUse of negative pressure wound therapy and multiple composite tissue flap transplantation appears to be an effective strategy for hand functional reconstruction in patients with mutilating hand injuries. Among the multiple composite tissue flaps, use of toe transplantation combined with reverse posterior interosseous artery flap appears to be the best option.

Project description:The omentum, external oblique musculocutaneous, and thoracoepigastric flaps are uncommonly used for chest wall reconstruction. Nevertheless, awareness and knowledge of these flaps is essential for reconstructive surgeons because they fill specific niche indications or serve as lifeboats when workhorse flaps are unavailable. The current report describes the anatomic basis, technical aspects of flap elevation, and indications for these unusual flaps.

Project description:Free tissue transfer has revolutionized the management of complex head and neck defects. Perforator flaps represent the most recent advance in the development of free flap surgery. These flaps are based on perforating vessels and can be harvested without significant damage to associated muscles, thereby reducing the postoperative morbidity associated with muscle-based flaps. Elevation of perforator flaps requires meticulous technique and can be more challenging than raising muscle-based flaps. Use of a Doppler device enables reliable identification of the perforating vessels and aids in the design of free-style free flaps, where the flaps are designed purely according to the perforator located. The major advantage of free-style free flaps is that an unlimited number of flaps can potentially be designed on much shorter pedicles. The anterolateral thigh flap is the most commonly used perforator flap in head and neck reconstruction. Its use is described in detail, as is use of other less common perforator flaps. This article also describes head and neck reconstruction in a region-specific manner and gives a short-list of suitable flaps based on the location of the defect.
