Outcome of dufourmentel flap versus conventional rhomboid (Limberg flap) in the treatment of complex pilonidal sinus: a randomized controlled study

Background Management of pilonidal disease lacks a single optimal treatment strategy, and recurrence is a problem for both the patient and the surgeon. Various flap-based treatment approaches are available for the treatment of such problems. This study aims to compare the outcome of dufourmentel flap versus conventional rhomboid in complex pilonidal diseases. Patients and methods The present randomized controlled study included 64 patients with complex pilonidal sinus, who were randomly divided into two groups: group A (n=32) patients underwent a dufourmentel flap while group B (n=32) patients underwent conventional rhomboid (Limberg flap). Follow-up was planned for early postoperative complications and recurrence as well as the aesthetic outcome. Results The mean age was 25.3±7.4 and 25.8±5.8.years in groups A and B, respectively. There was a statistically significant longer flap in group A when compared with group B (P=0.04). The mean operative time was 39.3±4.8 and 43±4.4 in groups A and B, respectively. Postoperative follow-up revealed a higher rate of complications in group B than in group A with a statistically significant difference in postoperative infection/discharge, hematoma, seroma, and partial flap loss. Conclusion Due to its adaptability, repeatability, clear, and predictable closure of the defect, and low recurrence rate, the authors suggest the dufourmentel flap as a suitable approach in the treatment of difficult and recurrent cases.

Outcome and Utility of First Dorsal Metacarpal Artery Flap for Finger Defects

Background: The First Dorsal Metacarpal Artery (FDMA) Flap or Foucher’s flap is an island pedicle flap proximally based on the first dorsal metacarpal artery and veins. A branch of radial sensory nerve is incorporated in the flap to make it a sensate flap. Objective: The aim of our study was to evaluate the functional and aesthetic outcomes of the seven FDMA flaps done over a period of four years for reconstruction of the distal thumb soft tissue defects and one defect over proximal phalanx of the index finger. Methods: This prospective study was performed between 2018 and 2022 at the Clinic of Reconstructive and Plastic Surgery. We present a series of six cases of distal thumb soft tissue defects and one patient with defect over the dorsal aspect of the index finger that were reconstructed with the FDMA flap. Results: In six patient donor site was grafted by full-thickness skin graft harvested from the groin and in one case was closed primary. All flaps survived and one case that was closed primary had donor site complication that was related to primary closure of the skin. All the patients had good fine touch and average two-point discrimination of 8.7 mm. Conclusion: FDMA flap is a useful and reliable flap to cover the defects of the dorsal aspect and to a certain extent the volar aspect of the thumb. We showed that can be used to cover the defects over proximal phalanx of the index finger. The flap provides adequate soft tissue coverage and good aesthetic results.

Inset techniques for the DIEP flap - what improves aesthetic outcomes?

The deep inferior epigastric perforator (DIEP) flap is widely considered as the gold standard in breast reconstruction. The inset technique of the DIEP flap is crucial in determining the overall aesthetic outcome; however, to date no systematic review is available that comprehensively assesses the various techniques. Evaluation of topic: A systematic review was performed according to the PRISMA guidelines. The methodology is outlined within our published protocol (Prospero CRD42023449477). Included articles met a minimal criterion compromising of the intervention (DIEP free flap for breast reconstruction) and outcomes (aesthetic and clinical outcomes). Six articles were included in this review, with a total of 346 patients and a follow-up ranging from 6 months to 4 years. Four articles were of a prospective case series study design, one article was a randomized controlled trial, and one article was a case-control study. The risk of bias was assessed to be high in the case series, but low and moderate in the randomized controlled trial and case-control study respectively. Although limited by the quality of the evidence, the single aesthetic unit principle, dual-plane inset, elimination of the need for a skin paddle, appropriate flap positioning and rotation, and algorithmic in-setting may all improve the aesthetic outcome of DIEP free flaps.

Pharyngeal flap outcomes for velopharyngeal insufficiency: Evaluation of speech, obstructive sleep apnea, and velopharyngeal anatomy

The purpose of this study was to evaluate the speech outcomes, reveal postoperative rates of obstructive sleep apnea, and characterize changes in the pharyngeal flap and velopharyngeal anatomy following pharyngeal flap surgery for velopharyngeal insufficiency. A retrospective chart was reviewed for patients with clefts who underwent pharyngeal flap surgery between November 2020 and November 2021. The data collected included age, gender, cleft palate type, age at pharyngeal flap surgery, postoperative complications, age and type of primary palatoplasty, preoperative and postoperative speech assessments, magnetic resonance imaging findings, and obstructive sleep apnea outcomes. The authors included 72 nonsyndromic patients who underwent pharyngeal flap surgery following cleft palate repair. The mean age at pharyngeal flap surgery was 10.6 ± 6.2 years. There was a significant improvement in the Pittsburgh Weighted Speech Score Hypernasality Component and the nasalance scores of oral syllables (p < 0.001). The obstructive sleep apnea rate after pharyngeal flap surgery was 6.9%. Compared to preoperatively, the velar angle was more acute (p < 0.001), the velar length was longer (p < 0.001), the distance of the velum tip to the posterior pharyngeal wall was shorter (p < 0.001), the size of velopharyngeal gap was narrower (p < 0.001), and the pharyngeal flap atrophied (p < 0.001) at 6 months postoperatively. The pharyngeal flap improved speech outcomes in patients with velopharyngeal insufficiency with a relatively low incidence of obstructive sleep apnea (6.9%). The velum is positioned more superiorly and posteriorly, and the size of the velopharyngeal gap is substantially reduced after pharyngeal flap surgery. In addition, the pharyngeal flap partially atrophied over time.

Primary Free Flaps for Coverage and Reconstruction in Acute Facial Trauma.

Background Acute facial trauma in motor vehicle accident defects may be associated with skeletal, neuromuscular, or mucosal losses. Simultaneous repair of the critical structures in these defects mandates the use of flap cover; paucity of local tissues necessitates the use of free skin flaps. Materials and Methods Six free flap reconstructions for acute facial trauma defects over a 10-year period were reviewed. The defect location, associated injuries, flap choice, additional reconstructive procedures, and flap outcomes were analyzed. Results There were four males and two females with ages between 18 and 63 years. Four defects were located in the lateral face and scalp, and two in the lower central face. Defect size ranged between 96 and 346 cm 2 . There were fractures in three, facial nerve injuries in two, and loss of facial muscles in one. Five free flaps were anterolateral thigh flap; simple and composite, one was a radial artery forearm flap. Recipient pedicles were the superficial temporal vessels in two and facial vessels in four cases. There were no re-explorations but one flap necrosed on 7th postoperative day on account of invasive aspergillosis. Discussion Use of free flaps for ballistic wounds is common. In uncommon nonballistic traumatic facial defects, the location, nature of the defect, and type of associated injuries and need for simultaneous reconstructions may dictate the use of free flaps and permit a one stage debridement, flap coverage, and a simultaneous reconstruction of lost functional units. Conclusion Free flap coverage in high velocity acute facial trauma defects offers a better possibility for primary reconstruction of associated facial injuries and helps in achieving better functional outcomes.

Free Flap Outcomes for Head and Neck Surgery in Patients with COVID-19.

Coronavirus disease 2019 (COVID-19) affects the vascular system, subjecting patients to a hypercoagulable state. This is of particular concern for the success of microvascular free flap reconstruction. This study aims to report head and neck free flap complications in patients with COVID-19 during the perioperative period. We believe these patients are more likely to experience flap complications given the hypercoagulable state. This is a multi-institutional retrospective case series of patients infected with COVID-19 during the perioperative period for head and neck free flap reconstruction from March 2020 to January 2022. Data was collected on 40 patients from 14 institutions. Twenty-one patients (52.5%) had a positive COVID-19 test within 10 days before surgery and 7 days after surgery. The remaining patients had a positive test earlier than 10 days before surgery. A positive test caused a delay in surgery for 16 patients (40.0%) with an average delay of 44.7 days (9-198 days). Two free flap complications (5.0%) occurred with no free flap deaths. Four patients (10.0%) had surgical complications and 10 patients had medical complications (25.0%). Five patients (12.5%) suffered from postoperative COVID-19 pneumonia. Three deaths were COVID-19-related and one from cancer recurrence during the study period. Despite the heightened risk of coagulopathy in COVID-19 patients, head and neck free flap reconstructions in patients with COVID-19 are not at higher risk for free flap complications. However, these patients are at increased risk of medical complications. 4 Laryngoscope, 134:4521-4526, 2024.

Mandible Reconstruction in a Rural Population: Comparison of Radial Forearm and Free Fibula Flap Outcomes.

Comparison of microsurgical reconstructive options after mandible resection is limited in the literature. Fibula free flaps (FFFs) can be costly and have timing limitations, but dental restoration can be performed, with varied reported rates of completion. The radial forearm free flap (RFFF) with mandible plating may be an alternative in select populations. The purpose of this study was to determine if the RFFF has similar outcomes to the FFF for mandible reconstruction in a rural population. A retrospective review of patients who underwent mandibulectomy from 2017 to 2021 at a single tertiary-care academic institution was performed. Those with FFF or RFFF reconstruction were included. Mandible defects were classified using the Jewer-Boyd H-C-L system. Sixty-eight patients were included with 53 undergoing FFF and 15 undergoing RFFF. Immediate reconstruction was significantly more common with RFFF than FFF (100% versus 64.2%; P =0.01). Lateral mandible defects were most common among both groups (52.9% FFF versus 73.3% RFFF; P =0.04). Osseous defect length was similar (9.5cm FFF versus 7.7cm RFFF; P =0.07), but soft tissue defect size was significantly larger in the RFFF group (28.6cm 2 versus 15.3cm 2 ; P =0.01). Complication rates (47.1% FFF versus 46.7% RFFF; P =0.98) and disease-free status at last follow-up (96.2% FFF versus 80.0% RFFF; P =0.06) were similar. Dental restoration occurred in 21.3% of patients undergoing FFF. Patients undergoing RFFF or FFF reconstruction after mandibulectomy had similar surgical and disease outcomes, with a low rate of completed dental restoration after FFF. Our findings suggest RFFF is a reasonable alternative to FFF for mandible reconstruction in select patients.

Introduction and preliminary application report for a novel 3D printed perforator navigator for fibular flap surgery

The aim of this study was to introduce and report on a 3D-printed perforator navigator and its clinical application.Integrated imaging and 3D printing techniques were employed for the design and manufacture of a perforator navigator. Key techniques included establishing a digital image coordinate system, localizing perforator fascia piercing points, creating a reference plane for the perforator course, and projecting the perforator course onto the body surface.All cases of maxillofacial defect repaired with free fibular myocutaneous flaps, from January 2019 to January 2022, were reinvestigated. Patients treated using traditional perforator localization methods were assigned into group Ⅰ, while those who had a navigator used during treatment were allocated to group Ⅱ. Outcome measurements included perforator positioning accuracy, perforator preparation time (PT), and flap growth score. Capillary refilling time and degree of flap swelling were recorded on the 1st, 3rd, and 7th days after surgery. On the 10th day after surgery, the flap survival situation was graded.In total, 25 patients were included in the study. Perforator preparation time for group Ⅱ was significantly less (p ＝ 0.04) than for group Ⅰ (1038.6 ± 195.4 s versus 1271.4 ± 295.1 s. In group Ⅱ, the mean positioning deviation for the perforator navigator was 2.12 cm less than that for the high-frequency color Doppler (p ＝ 0.001). Group Ⅱ also had a higher score than group Ⅰ for overall flap growth evaluation (nonparametric rank sum test, p ＝ 0.04).Within the scale of the study, it seems that perforator localization and navigation using a 3D-printed navigator is technically feasible, and helps to improve the clinical outcome of free fibular flaps. The perforator navigator will play a useful role in displaying the perforator course, improving the accuracy of perforator localization, reducing surgical injury, and ultimately enhancing flap success rate.

Evaluating the Association Between Flap Monitoring and DIEP Flap Outcomes in Postmastectomy Patients at Mayo Clinic, Florida

Reevaluating Thrombocytosis as a Risk Factor in Free Flap Surgery

Introduction Thrombocytosis, defined as a platelet count &gt;400,000, has been implicated as a risk factor in free flap failure. Despite proposed mechanisms of pedicle thrombosis, recent studies have suggested that thrombocytosis has no effect on free tissue transfer viability. Risk factors that may compromise successful free tissue transfer should be understood and elucidated, with particular attention to thrombocytosis and its conflicting evidence in the literature. We hypothesize that thrombocytosis has no bearing on free flap success or the rates of pedicle thrombosis. Methods Our institution performed a retrospective chart review on all patients who underwent free flap reconstruction over the past 6 years. Patient demographics, medical history, type and location of free tissue transfer, preoperative platelets, postoperative platelets, and flap outcomes and complications (wound dehiscence, infection, hematoma, seroma, and need for blood transfusion) were recorded. Independent t test, Mann-Whitney U tests, χ 2 test, and Fisher exact tests were used to determine P values to compare flap outcomes in patients with thrombocytosis (platelet count &gt;400,000) and those with platelet counts less than 400,000. Results In our 502-patient cohort, 71 were found to have a platelet count &gt;400,000 (35 preoperatively and 36 postoperatively) and 431 patients had platelet counts &lt;400,000. There were 42 reconstructive failures (flap success rate of 91.6%) and 111 returns to the operating room (OR). For patients with postoperative thrombocytosis, 24 flaps returned to the OR (44.4%), whereas in patients without thrombocytosis, 87 flaps returned to the OR (19.4%; P &lt; 0.001). In patients with postoperative thrombocytosis, 10 OR returns were due to pedicle venous thrombosis (18.5%), in comparison to 10 returns for venous thrombosis in those with normal platelets (2.2%; P &lt; 0.001). There was a small difference in free flap success rates between those with postoperative thrombocytosis and normal platelets, 88.7% versus 92.11%; however, this was not statistically significant (P = 0.71). The thrombocytosis group had a higher incidence of overall postoperative complications (P = 0.002). Conclusions Thrombocytosis has historically been cited as a risk factor for free flap reconstruction failure with recent conflicting evidence in the literature. In patients with postoperative thrombocytosis, we found an increased risk of venous thrombosis; however, this did not result in increased flap failure. There was an increase in postoperative complications, which corresponds with National Surgical Quality Improvement Program data reported in the literature. We suspect that thrombocytosis is not a harbinger of free flap failure but rather a marker for overall inflammation, which may confer a higher rate of venous thrombosis requiring reoperation and postoperative complications.

Microvascular Free Flap Outcomes in Maxillectomy Defects from Invasive Fungal Sinusitis.

Microvascular free tissue transfer is routinely used for reconstructing midface defects in patients with malignancy, however, studies regarding reconstructive outcomes in invasive fungal sinusitis (IFS) are lacking. We aim to describe outcomes of free flap reconstruction for IFS defects, determine the optimal time to perform reconstruction, and if anti-fungal medications or other risk factors of an immunocompromised patient population affect reconstructive outcomes. Retrospective review of reconstruction for IFS (2010-2022). Age, BMI, hemoglobin A1c, number of surgical debridements, and interval from the last debridement to reconstruction were compared between patients with delayed wound healing versus those without. Predictor variables for delayed wound healing and the effect of time on free flap reconstruction were analyzed. Twenty-seven patients underwent free flap reconstruction for IFS. Three patients were immunocompromised from leukemia and 21 had diabetes mellitus (DM). Patients underwent an average of four surgical debridements for treatment of IFS. The interval from the last IFS debridement to flap reconstruction was 5.58 months (±5.5). Seven flaps (25.9%) had delayed wound healing. A shorter interval of less than 2 months between the last debridement for IFS and reconstructive free flap procedure was associated with delayed wound healing (Fisher Exact Test p = 0.0062). Other factors including DM, BMI, HgA1c, and bone reconstruction were not associated with delayed wound healing. Patients with maxillectomy defects from IFS can undergo microvascular-free flap reconstruction with good outcomes while on anti-fungal medication. Early reconstruction in the first 2 months after the last IFS debridement is associated with delayed wound healing. 4 Laryngoscope, 134:1642-1647, 2024.

Comparing microsurgical breast reconstruction outcomes following postoperative monitoring techniques: a systematic review and meta-analysis of 2529 patients

Aims: This paper aims to assess the existing evidence regarding oximetry and thermography by comparing postoperative rates of complications following microsurgical breast reconstruction. Methods: A systematic review of PubMed, Web of Science, and Cochrane was completed. A qualitative and quantitative analysis of all included studies was then performed. Results: Fourteen studies were included with a total population of 2,529 female patients who underwent microvascular breast reconstruction, ultimately totaling 3,289 flaps. The mean age for the cohorts included in this study ranged from 48.9 to 57 years of age. A total of 15 complete flap losses were reported. Furthermore, this meta-analysis of proportion showed that total flap loss experienced was 0% (95%CI 0%-100%) for patients monitored with thermography compared to 0% (95%CI 0%-1%) for those monitored with oximetry. Partial flap loss occurred at a frequency of 1% [95% confidence interval (CI) 0%-73%] for patients monitored with thermography compared to 1% (95%CI 0%-2%) for those monitored with oximetry. Furthermore, the results of this study showed that thermography prompted a return to the operating room (OR) in 1% (95%CI 0%-73%) of the patients compared to 5% (95%CI 3%-9%) for oximetry. Lastly, the overall complication rate was 12% (95%CI 1%-54%) for patients monitored with thermography compared to 10% (95%CI 4%-21%) for those monitored with oximetry. Conclusion: Ultimately, this meta-analysis concludes that while oximetry monitoring currently has strong evidence for improving flap outcomes, trends in the current data indicate that further studies may demonstrate that thermography may be comparable to oximetry in achieving similar patient outcomes.

750 Fluid Therapy Regimen and Free Flap Failure in Post-Resection Reconstruction for Head and Neck Cancer: A Systematic Review

Abstract Background The importance of developing standardized approaches away from wide-range fluid administration regimens has been growing. The aim of the following study is to evaluate the current evidence with regards to fluid therapy regimens and their effects on flap complications in free-flap reconstruction of head and neck cancer. Method A systematic database search was conducted of original articles that included fluid therapy regimens in free-flap reconstruction of head and neck cancer in EMBASE, MEDLINE, Cochrane database and Google Scholar, from inception to January 2021. Our main outcomes were presence of a flap complication or failure and total length of hospital stay. Results We identified 327 studies from our search, of which 11 studies met the inclusion criteria, comprising a total of 1,133 patients. Five studies showed that greater perioperative fluid volume was associated with higher rates of flap complication, with one drawing a cut-off at 5.5 L to predict any flap complication and 7 L to predict a major complication that required re-operation. Three studies assessed goal directed fluid therapy, with two showing significantly reduced intraoperative fluid volume within this group, but no significant difference in flap outcomes. Two studies comparing crystalloid and colloid fluids concluded that there was no significant difference in outcomes when using either. Conclusions Excessive fluid administration negatively impacts surgical outcomes. Goal directed therapy presents insufficient evidence as a method for reducing flap complications and length of hospital stay. The clinical benefit of colloid fluid intra-operatively over crystalloids have not been unanimously demonstrated in this review.

Outcome of Superomedial Pedicle Flap for Lower Outer Quadrant Breast Cancer

Abstract Background Breast cancer is the most common cancer among women and is the second leading cause of cancer deaths. The surgical treatment of patients with breast cancer involves either breast conserving surgery or mastectomy, both of which can result in considerable asymmetry of the breasts. Breast reconstruction offers restoration of breast symmetry to such women. The patient needs to be aware that the reconstructed breasts will neither feel nor function like a normal breast but may help in restoring body image and self-confidence. Objective To evaluate the intraoperative and postoperative outcomes and showing advantages and disadvantages of Superiomedial pedicle flap for lower outer quadrant breast cancer in cup ≥ c. Patients and Methods It was a prospective study that included 10 patients aiming to assess outcome of the superomedial pedicle flap oncoplastic technique for lower outer quadrant breast cancer in oversized breast. This study was conducted at Ain Shams University Hospitals. Approval of the ethics committee and written informed consent from all participants were obtained. Results In our study, all of the patients had free safty magins as confirmed by the pathologist in our MDT proving that we had performed a superior medial technique safely from the oncological point of view. We were able to conduct an excellent cosmetic outcome for relatively large tumor excisions which fall in good and fair score groups as those two patients noticed asymmetry of the two breasts. None of our cases have had a poor or an ugly score. Overall, the satisfaction rate with this technique was high, with very few and easily manageable complications. There were no cases of NAC loss. Conclusion Superomedial pedicle can be safely utilized in large size breast reduction without increase of NAC necrosis. The technique is an efficient method to achieve minimal to moderate breast reduction with minimal NAC transposition. The primary surgical goals are attained by appropriate resection of the breast parenchyma. Moreover, a youthful and aesthetically appealing breast is achieved by maintaining superior and medial fullness and reshaping the breast using the parenchyma and skin envelope for support. Superomedial pedicle flap technique offers breastconserving surgery with wider margins offering safer oncologic control with more satisfactory cosmetic outcome.

The outcomes of peroneal artery perforator-based propeller flaps for the treatment of infected lateral malleolar bursitis

Purpose: Infected malleolar bursitis sometimes requires multiple debridements, followed by soft tissue reconstruction with a flap. The purpose of this study was to evaluate the clinical outcomes of patients with infected lateral malleolar bursitis who were treated using peroneal artery perforator-based propeller flaps. Methods: We retrospectively included 10 patients who underwent reconstruction of the lateral malleolus with a peroneal artery perforator-based propeller flap due to infected lateral malleolar bursitis between 2014 and 2022. Results: The average follow-up time was 77.2 weeks. Six patients experienced complete healing; three developed partial flap necrosis, and one had a long-lasting seroma. All patients with complications had long-term diabetes. Conclusion: Partial flap necrosis in patients with diabetes may occur because of impaired microcirculation. A peroneal artery perforator-based propeller flap could be useful for soft tissue reconstruction in select patients without diabetes or in patients with diabetes who have infected lateral malleolar bursitis.

A simple free flap strategy using end-to-side anastomosis to the main vessels in injured extremity

BackgroundDuring free flap surgery, the surgeon sometimes encounters problems with anastomosis such as intractable arterial spasms or vessel size discrepancy in venous anastomoses. End-to-side (ETS) anastomosis has the advantages of limited chance of vessel spasm and easy handling by adjusting for vessel size discrepancy. We introduced the arterial and venous end-to-side anastomosis (AV-ETS) strategy, which is based on the ETS anastomosis to the main artery and accompanying veins, to avoid intraoperative anastomotic problems when creating a free flap. The aim of this study was to compare flap outcomes and intraoperative anastomotic problems before and after introduction of the AV-ETS strategy in extremity free flap surgery. Materials and methodsWe retrospectively examined 72 consecutive extremity free flaps. Before introducing the AV-ETS strategy, we used the conventional strategy in which the recipient artery was selected according to the number of the remaining main artery and the anastomosis technique was flexibly changed, although the end-to-end (ETE) technique was used in most cases. ResultsThe conventional group had 18 flaps and the AV-ETS group had 54 flaps. The rate of flap survival did not differ between these groups, and there were no cases of flap failure after the introduction of the AV-ETS strategy. The AV-ETS group had significantly fewer flaps that required a change in preoperative planning for the recipient artery or anastomotic site of the artery. ConclusionsThe AV-ETS strategy may facilitate reliable preoperative planning and the performance of stable free flap surgery without requiring a flexible response during surgery.

Outcomes of Head and Neck Free Tissue Transfer in Renal Failure Patients.

To assess if there is increased risk of free flap failure in renal failure patients undergoing head and neck reconstruction. We seek to primarily assess free flap outcomes based on stages of chronic kidney disease (CKD) and secondarily determine increased risk for postoperative complications. Retrospective chart review was performed at five tertiary care centers. Patients were identified that had undergone microvascular free flap reconstruction of the head and neck with diagnosis of renal failure, classified as Stage 3 CKD or higher. Demographic data was collected. Outcomes in the postoperative period were examined. Seventy-three patients met inclusion criteria. The average patient age was 69 years with a male predominance (n = 48). The majority of patients had CKD Stage 3 (n = 52). Overall flap failure rate was 12.33% (n = 9, CKD stage 3 = 7.69%, CKD stage 4 = 30%, CKD stage 5 = 18%). There was an increased risk of flap failure on multivariate analysis for CKD stage 4/5 patients when compared to CKD 3 patients (p = 0.0095). When compared to matched controls, there was an increased risk of flap failure in CKD patients (p = 0.01) as well as an increased risk of overall complications (p < 0.0001). Patients with CKD undergoing head and neck reconstruction are at a higher risk of flap failure and overall complications. When comparing CKD stages there may be increased risk of flap failure in later stages of CKD compared to CKD 3. Appropriate patient counseling is recommended pre-operatively in this patient population with consideration for regional flaps in the appropriate patient. 3 Laryngoscope, 134:688-694, 2024.

How to get the most out of your gastrocnemius and soleus flaps

Summary: Gastrocnemius and soleus flaps represent the workhorse local flaps to cover soft tissue defects of the proximal 1/3 and middle 1/3 of the leg, respectively. An important consideration before conducting a local flap is whether the flap can provide adequate coverage. The utility of the gastrocnemius flap can be increased using multiple techniques to increase the arc of rotation including the posterior midline approach, dissection at the pes anserinus and medial femoral condyle origin, scoring the fascia, and inclusion of a skin paddle. Concerning the soleus flap, the hemisoleus flap represents a technique to increase the arc of rotation. With a soleus flap, one must consider the soft tissue defect location, size, and perforator blood supply because these factors influence what soleus flap technique to use. This article discusses how to make the most out of gastrocnemius flaps and soleus flaps regarding maximizing coverage and ensuring successful flap outcome.

A comparative study of clinical outcome in ALT free flap reconstruction using superficial or deep and single or dual recipient vein anastomosis in different sites

AbstractBackgroundDuring the free flap surgery obtaining a suitable recipient vein is an important factor for successful outcome. As in all other flaps even in ALT flap, single or double venous anastomosis, superficial or deep venous anastomosis is still a matter of debate among the micro vascular surgeons. Though dual vein anastomosis is a time‐tested method, single vein anastomosis has the advantage of reducing the operative time and hospitalization cost. Similarly, in situation where the deep veins are dubious superficial veins are savior. This study explores the outcome of ALT flap using different system of recipient veins.Patients and MethodsRetrospective analysis of the 54 free ALT flaps performed over a period of 5 years from June 2017 till June 2022, was carried out. Out of 54, 38 (63%) were male patients and 16 (37%) were females. The outcome of the flaps was evaluated in single or dual anastomosis group. Similarly, the outcome of the flaps with deep or superficial vein anastomosis was also evaluated. The flaps outcomes are evaluated as favorable (successful as well as partial loss are considered as favorable) and unfavorable (complete loss of the flap).ResultsAmong the 54 flaps, 31 patients had lower limb reconstruction, majority were post‐traumatic defects. Twenty patients had head and neck reconstruction following post malignancy excision. Three patients had upper‐limb reconstruction for post traumatic and burn injury defects. The outcome was analyzed. Twenty patients had dual vein anastomosis, 90% (18 out of 20) of patients had favorable outcome and 10% (2 out of 20) had unfavorable outcome. Thirty‐four patients underwent single vein anastomosis, 94% had favorable outcome and 6% had unfavorable outcome. The result was not statistically significant as p &lt; .05. Seven patients underwent superficial vein recipient anastomosis, and all flaps were (100%) successful and no failure, whereas out of 27 patients who had undergone deep vein anastomosis 25 (92%) had favorable outcome and 2 (8%) had unfavorable outcome. The results were not statistically significant as p &gt; .05.ConclusionAs in other free flaps venous anastomosis compromise is the cause for flap failure in majority of the times. Whenever possible, dual vein anastomosis should be considered. But when impervious, single vein anastomosis can be resorted to without any hesitation. Similarly, unavailability of deep veins should not deter the surgeons. Superficial veins were a savior in such situation and can be advantageous too.

Surgical outcomes of suprafascial and subfascial radial forearm free flaps in head and neck reconstruction.

Conventional radial forearm free flaps (RFFFs) are known to be safe, but can result in donor site complications. Based on our experiences with suprafascial and subfascial RFFFs, we evaluated the safety of flap survival and surgical outcomes. This was a retrospective study of head and neck reconstructions using RFFFs from 2006 to 2021. Thirty-two patients underwent procedures using either subfascial (group A) or suprafascial (group B) dissection for flap elevation. Data were collected on patient characteristics, flap size, and donor and recipient complications, and the two groups were compared. Thirteen of the 32 patients were in group A and 19 were in group B. Group A included 10 men and three women, with a mean age of 56.15 years, and group B included 16 men and three women, with a mean age of 59.11 years. The mean defect areas were 42.83 cm² and 33.32 cm², and the mean flap sizes were 50.96 cm² and 44.54 cm² in groups A and B, respectively. There were 13 donor site complications: eight (61.5%) in group A and five (26.3%) in group B. Flexor tendon exposure occurred in three patients in group A and in none in group B. All flaps survived completely. A recipient site complication occurred in two patients (15.4%) in group A and three patients (15.8%) in group B. Complications and flap survival were similar between the two groups. However, tendon exposure at the donor site was less prevalent in the suprafascial group, and the treatment period was shorter. Based on our data, suprafascial RFFF is a reliable and safe procedure for reconstruction of the head and neck.
