Pedicled Flap Reconstruction Research Articles

Racial Disparities in 30 Day Outcomes Following Total Laryngectomy.

Despite the growing literature on racial disparities in the utilization of total laryngectomy (TL), and survival following the treatment of laryngeal cancers, there is a paucity of research in TL cohorts evaluating disparities in the immediate postoperative setting. In a national multi-institutional cohort, TL cases between 2010 and 2021 were identified using relevant Current Procedural Terminology (CPT) codes. Logistic regression analyses investigated the association between race/ethnicity and adverse outcomes within 30 days postoperatively. This study consisted of 1493 patients who underwent TL with or without radical neck dissection. Black patients underwent free flap and pedicled flap reconstruction more frequently than their counterparts (P = .023) and exhibited a 1.532 times higher odds of surgical complications (P < .001). There are increased rates of surgical complications in Black patients undergoing TL. Given the limited oncologic and socioeconomic variables available through National Surgical Quality Improvement Program, future study of disparate postoperative outcomes in this population is recommended.

Concurrent plate fixation and pedicled flap coverage for open fractures complicated by soft tissue loss of the tibia in pediatric cohort: a clinical series.

The optimal treatment of open fractures complicated by soft tissue loss of pediatric tibial fractures remains inconclusive. The author described a protocol of concurrent plate fixation and pedicled flap coverage and retrospectively reviewed the outcomes of such injuries. A total of 25 pediatric cases with Gustilo lllB open tibial fracture were treated by single-stage plate fixation and pedicled flap reconstruction. The reviewed information consisted of time to fix and flap, type of plate, type of pedicled flap, fracture union time, postoperative complication and the clinical outcomes by objective scoring system. Fix and flap was undergone between 7 and 12days after injury with the average time of 8.2days. Regarding the type of plate, narrow LCP was applied in 8, 3.5mm precontoured LCP in 10, 5.0mm precontoured in 2 and double LCP in 5. According to soft tissue reconstruction, the medial gastrocnemius flap was selected in 6 cases, myocutaneous medial gastrocnemius flap in 2, soleus flap in 3, hemisoleus flap in 5, reverse sural flap in 6 and combined medial gastrocnemius and hemisoleus flaps in 3. No flap-related complication was demonstrated. All cases established fracture union in between 12 and 24weeks with an average time to union of 17.7weeks. According to postoperative complications, infected plate occurred in 2 cases and implant irritation in 5. According to Puno functional score, excellent results were presented in 7 cases and good results in 18 cases. Single-stage plate fixation and pedicled flap coverage are a reliable regimen for pediatric open fractures complicated by soft tissue loss of the tibia.

The Vertical Profunda Artery Perforator Flap for Perineal Reconstruction.

Colorectal cancer is a significant cause of cancer-related death in the United States with abdominoperineal resection (APR) remaining a necessary procedure for many patients. The resultant defects of this radical operation are complex and characterized by significant tissue voids. Pedicled vertical profunda artery perforator flaps (vPAP) can be used to obliterate these defects in patients receiving minimally invasive APR or when the abdominal donor site is unavailable. After receiving local institutional review board approval, a single center, retrospective cohort study from January 2020 to December 2021 was performed assessing pedicled vPAP flap reconstruction of APR defects. Age, sex, body mass index, primary diagnosis, comorbidities, concomitant oncologic procedures, radiation, timing, incorporation of gracilis flaps, follow-up, and complications were compared. Ten patients (70% male) with an average age of 56.2 years and BMI of 27.6 were included in the study. Rectal adenocarcinoma (50%) was the most common indication for APR, followed by rectal squamous cell carcinoma (30%), vulvar squamous cell carcinoma (10%), and Crohn disease (10%). Eighty percent of the patients received radiation, and 70% of reconstructions were delayed after the initial resection. The average length of clinical follow-up was 26.1 months. Concerning major complications, 2 patients were required to return to the operating room due to venous congestion (20%), and 2 patients suffered partial flap failure (20%). Minor complications were perineal dehiscence (50%), abscess requiring percutaneous drainage by interventional radiology (30%), and infection requiring antibiotics (20%). Twenty percent of patients developed fistulas requiring surgical excision. There were no instances of donor site dehiscence, and there was no complete flap loss, indicating successful reconstruction in all included cases. vPAP flaps are a reliable method to reconstruct perineal defects with less donor-site morbidity than previous reconstructive options. vPAP flaps should be considered in the setting of delayed reconstruction, minimally invasive APRs, and when the abdominal donor site is unavailable.

How to increase the success rate in microsurgical free and pedicled flap reconstructions with intraoperative multistep ICG imaging: A case series with 400 consecutive cases

BackgroundOver the last decade, microsurgical soft tissue transfer became the gold standard for a wide variety of reconstructions throughout the body. Continued improvement of instruments and surgical techniques allowed reaching a very high success rate, like the employment of intra-operative indocyanine green angiography (ICG-A). This study aims to assess and validate the role of a standard intraoperative ICG-A in free flap and pedicled flap surgery to improve the overall outcomes. Patients and MethodsFrom April 2018 and April 2023, four hundreds consecutive patients who underwent reconstruction using free flap and pedicled flap were enrolled. The ICG-A was always performed in free flap after elevation of the flap, after microsurgical anastomosis, immediately after the flap inset and after wound closure; in pedicled flap the sequential procedure was performed after elevation of the flap, after flap inset and after wound closure. ResultsAll four hundred patients who underwent flap reconstruction using intraoperative ICG angiography had an extremely low incidence of necrosis (0.75% partial necrosis among free flaps and pedicled flaps) and reoperation for perfusion-related complications (0.75% due to acute ischemia and 0.50% due to flap congestion). Minor complications like hematoma, seroma, wound dehiscence, and wound infections were managed with a second operation. No flaps were lost and all the patients were successfully treated. ConclusionsThe present report shows how the employment of systematic multiple-steps ICG angiography for intra-operative assessment of both free and pedicled flap’s perfusion can significantly reduce the complications rate, including flap loss and re-exploration surgeries, in a time- and cost-effective manner.

A Systematic Review of Clinical Outcomes of Pedicled Flap Repairs of the Knee Extensor Mechanism.

Rupture of the extensor mechanism of the knee has severe functional morbidity, and repair can be complicated by infection, allograft degeneration, and recurrent rupture. Techniques of autologous tissue repair utilizing pedicled flaps such as the gastrocnemius offer vascularized methods of reconstruction, with potentially diminished complication rates. The goal of this study was to evaluate the functional outcomes and complications associated with pedicled flap repair of the knee extensor mechanism. A systematic review was conducted following the Preferred Reporting Items for Systemic Reviews and Meta-Analyses guidelines. Publications that focused on local myocutaneous flaps as a means for reconstruction were included. Causes for knee extensor mechanism deficit, flap characteristics, ambulation rate, changes in range of motion pre- and postoperation, and postoperative complications were analyzed. Technique reports including primary suture repairs, synthetic mesh, and allograft use were excluded. An initial 119 studies were identified, with final review of 22 observational studies encompassing 128 cases of pedicled flap reconstructions. The gastrocnemius (88.2%, n = 113), quadriceps (6.3%, n = 8), and a combination of the vastus and gastrocnemius flaps (5.5%, n = 7), were the most frequently utilized flaps. Functional outcomes were favorable with 87.2% of patients achieving ambulation without external support. Variability in range of motion outcomes across different flap may be secondary to the patient characteristics as well as extent of initial injury. Autologous pedicle flap reconstruction of the knee extensor mechanism emerges as a viable option for cases characterized by extensive defects and insufficient soft tissue coverage, which are not amenable to direct suture repairs or allografts. Postoperative assessments revealed that the majority of patients experienced improved ambulation status, with no instances of deterioration noted among the patients.

A nomogram for predicting outcomes following pedicled flap reconstruction of the lower extremity

IntroductionLower extremity reconstructions with soft tissue flaps account for a significant proportion of reconstructive surgery. Pedicled flaps are a procedure of choice, particularly in multimorbid patients and those with small to medium-sized defects. Complication rates are high and should not be underestimated, with accurate preoperative risk factor assessment being imperative. MethodsUsing the American College of Surgeons National Surgical Quality Improvement Program Database (2008–2021), we analyzed all patients who underwent pedicled flap reconstruction of the lower extremity. Demographic data, comorbidities, and perioperative data were extracted. We identified risk factors of major surgical complications within 30 days of surgery through uni- and multivariate regression analyses. On this basis, a nomogram for predicting the risk of complications was developed to allow for feasible point-of-care risk assessment. ResultsA total of 6475 adult patients were identified. The most common comorbidities were hypertension (n = 3363, 51.9%) and obesity (n = 2306, 35.6%) and most common American Society of Anesthesiologists (ASA) class was class 3 (n = 3703, 57.2%). The most common complication was bleeding/transfusion (n = 1293, 19.9%). Multivariate regression revealed longer procedures, inpatient setting, higher ASA scores, hypertension, and procedures performed by orthopedic and vascular surgeons as predictors for higher risk of post-operative complications. ConclusionLeveraging a risk- and case-mix-adjusted multi-institutional database, a nomogram for post-operative surgical complications within 30 days after pedicled flap reconstruction in the lower extremity was developed. This broadly applicable risk prediction tool can aid in decision-making when assessing patient eligibility.

Advancing indocyanine green fluorescence flap perfusion assessment via near infrared signal quantification

IntroductionIntraoperative indocyanine green fluorescence angiography (ICGFA) perfusion assessment has been demonstrated to reduce complications in reconstructive surgery. This study sought to advance ICGFA flap perfusion assessment via quantification methodologies. MethodPatients undergoing pedicled and free flap reconstruction were subjected to intraoperative ICGFA flap perfusion assessment using either an open or endoscopic system. Patient demographics, clinical impact of ICGFA and outcomes were documented. From the ICGFA recordings, fluorescence signal quality, as well as inflow/outflow milestones for the flap and surrounding (control) tissue were computationally quantified post hoc and compared on a region of interest (ROI) level. Further software development intended full flap quantification, metric computation and heatmap generation. ResultsFifteen patients underwent ICGFA assessment at reconstruction (8 head and neck, 6 breast and 1 perineum) including 10 free and 5 pedicled flaps. Visual ICGFA interpretation altered on-table management in 33.3% of cases, with flap edges trimmed in 4 and a re-anastomosis in 1 patient. One patient suffered post-operative flap dehiscence. Laparoscopic camera use proved feasible but recorded a lower quality signal than the open system.Using established and novel metrics, objective ICGFA signal ROI quantification permitted perfusion comparisons between the flap and surrounding tissue. Full flap assessment feasibility was demonstrated by computing all pixels and subsequent outputs summarisation as heatmaps. ConclusionThis trial demonstrated the feasibility and potential for ICGFA with operator based and quantitative flap perfusion assessment across several reconstructive applications. Further development and implementation of these computational methods requires technique and device standardisation.

Outcomes of centrally versus laterally based tarsoconjuctival pedicle flap reconstruction for large full thickness lower eyelid defects.

To compare the outcomes of two types of tarsoconjunctival pedicle flaps for reconstruction of large lower eyelid defects. Retrospective medical record review of consecutive patients who underwent centrally-based or laterally-based tarsoconjunctival pedicle transconjunctival flap for lower eyelid reconstruction for defects greater than 50% of the lid margin. Full thickness skin grafts were used for anterior lamellar reconstruction in all cases. The primary outcome measure was eyelid position, function and satisfactory cosmesis. Forty-three patients were identified. Twenty-six patients underwent reconstruction with a centrally-based tarsoconjunctival pedicle flap; 17 patients underwent reconstruction with a laterally-based tarsoconjunctival pedicle flap. The average size of the lid defect was 77.7% (range 50-100%) in the central group and 75% (range 50-100%) in the lateral group (p=0.604). Mean follow up time was 61.5 weeks in the central group and 46.6 weeks in the lateral group (p=0.765). After division of the flap and during follow up, 27% of the centrally based group required revisional surgery with none in the laterally based group (p=0.03). 100% of the patients with centrally based flaps required second staged division of flap, whereas only 52% of patients with a laterally based flaps underwent second staged flap division. (p<0.001). Outcome suggests that for reconstruction of large lower lid defects requiring lid sharing procedures, both centrally and lateral-based procedures have equivalent functional outcome. However, the laterally based group has less need for revisional procedures and may not need a second stage division of the flap.

Pedicled omental flaps for complex wound reconstruction following surgery for primary spine tumors of the mobile spine and sacrum.

Surgery for primary tumors of the mobile spine and sacrum often requires complex reconstruction techniques to cover soft-tissue defects and to treat wound and CSF-related complications. The anatomical, vascular, and immunoregulatory characteristics of the omentum make it an excellent local substrate for the management of radiation soft-tissue injury, infection, and extensive wound defects. This study describes the authors' experience in complex wound reconstruction using pedicled omental flaps to cover defects in surgery for mobile spine and sacral primary tumors. A retrospective cohort analysis was conducted on 34 patients who underwent pedicled omental flap reconstruction after en bloc resection of primary sacral and mobile spine tumors between 2010 and 2020. The study focused on assessing the indications for omental flap usage, including soft-tissue coverage, protection against postoperative radiation therapy, infection management, vascular supply for bone grafts, and dural defect and CSF leak repair. Patient demographic characteristics, tumor characteristics, surgical outcomes, and follow-up data were analyzed to determine the procedure's efficacy and complication rates. From 2010 to 2020, 34 patients underwent pedicled omental flap reconstruction after en bloc resection of sacral (24 of 34 [71%]) and mobile spine (10 of 34 [29%]) primary tumors, mostly chordomas. The patient cohort included 21 men and 13 women with a median (range) age of 60 (32-89) years. The most common indication for omental flap was soft-tissue coverage (20 of 34 [59%]). Other indications included protecting abdominopelvic organs for postoperative radiation therapy (6 of 34 [18%]), treating infections (5 of 34 [15%]), providing vascular supply for free fibular bone graft (1 of 34 [3%]), and repairing large dural defects and CSF leak (2 of 34 [6%]). The median (range) follow-up was 24 (0-132) months, during which 71% (24 of 34) of patients did not require additional surgery for wound-related complications. At last follow-up, 59% (20 of 34) had stable disease and 32% (11 of 34) had recurrence, had progression of disease, or had been discharged to hospice after treatment. The pedicled omentum is an effective local tissue graft that can be used for complex wound reconstruction and management of high-risk closures in primary spine tumors. This technique may have a lower rate of complications than other approaches and may influence surgical planning and flap selection in challenging cases.

Multimodality Imaging of Postmastectomy Breast Reconstruction Techniques, Complications, and Tumor Recurrence.

For women undergoing mastectomy, breast reconstruction can be performed by using implants or autologous tissue flaps. Mastectomy options include skin- and nipple-sparing techniques. Implant-based reconstruction can be performed with saline or silicone implants. Various autologous pedicled or free tissue flap reconstruction methods based on different tissue donor sites are available. The aesthetic outcomes of implant- and flap-based reconstructions can be improved with oncoplastic surgery, including autologous fat graft placement and nipple-areolar complex reconstruction. The authors provide an update on recent advances in implant reconstruction techniques and contemporary expanded options for autologous tissue flap reconstruction as it relates to imaging modalities. As breast cancer screening is not routinely performed in this clinical setting, tumor recurrence after mastectomy and reconstruction is often detected by palpation at physical examination. Most local recurrences occur within the skin and subcutaneous tissue. Diagnostic breast imaging continues to have a critical role in confirmation of disease recurrence. Knowledge of the spectrum of benign and abnormal imaging appearances in the reconstructed breast is important for postoperative evaluation of patients, including recognition of early and late postsurgical complications and breast cancer recurrence. The authors provide an overview of multimodality imaging of the postmastectomy reconstructed breast, as well as an update on screening guidelines and recommendations for this unique patient population. ©RSNA, 2024 Test Your Knowledge questions for this article are available in the supplemental material.

Low-molecular-weight heparin salvage in pedicled flap reconstruction in head and neck: a prospective cohort study.

To determine if systemic administration of low-molecular-weight heparin impacts venous compromise in loco-regional flap reconstruction for head and neck subsites. This prospective study was conducted on patients who had developed features of venous compromise of the flap. The case group received low-molecular-weight heparin (dalteparin). Of the 73 patients who developed venous congestion, low-molecular-weight heparin was administered in 47 patients. In the low-molecular-weight heparin subset, 23 patients had either reversal or non-progression of venous compromise (48.9 per cent). Of the patients who had no response to low-molecular-weight heparin rescue, complete necrosis was seen in 4 and partial flap necrosis was observed in 19. The corresponding numbers in the control group were 13 and 12, respectively (odds ratio 23.9, p = 0.002). Additionally, the low-molecular-weight heparin arm had a lower incidence of partial or complete flap necrosis (p = 0.002). Low-molecular-weight heparin salvage, when instituted early, is likely to result in a significant reduction in flap-related morbidity.

Premastectomy Radiotherapy and Immediate Breast Reconstruction

Premastectomy radiotherapy (PreMRT) is a new treatment sequence to avoid the adverse effects of radiotherapy on the final breast reconstruction while achieving the benefits of immediate breast reconstruction (IMBR). To evaluate outcomes among patients who received PreMRT and regional nodal irradiation (RNI) followed by mastectomy and IMBR. This was a phase 2 single-center randomized clinical trial conducted between August 3, 2018, and August 2, 2022, evaluating the feasibility and safety of PreMRT and RNI (including internal mammary lymph nodes). Patients with cT0-T3, N0-N3b breast cancer and a recommendation for radiotherapy were eligible. This trial evaluated outcomes after PreMRT followed by mastectomy and IMBR. Patients were randomized to receive either hypofractionated (40.05 Gy/15 fractions) or conventionally fractionated (50 Gy/25 fractions) RNI. The primary outcome was reconstructive failure, defined as complete autologous flap loss. Demographic, treatment, and outcomes data were collected, and associations between multiple variables and outcomes were evaluated. Analysis was performed on an intent-to-treat basis. Fifty patients were enrolled. Among 49 evaluable patients, the median age was 48 years (range, 31-72 years), and 46 patients (94%) received neoadjuvant systemic therapy. Twenty-five patients received 50 Gy in 25 fractions to the breast and 45 Gy in 25 fractions to regional nodes, and 24 patients received 40.05 Gy in 15 fractions to the breast and 37.5 Gy in 15 fractions to regional nodes, including internal mammary lymph nodes. Forty-eight patients underwent mastectomy with IMBR, at a median of 23 days (IQR, 20-28.5 days) after radiotherapy. Forty-one patients had microvascular autologous flap reconstruction, 5 underwent latissimus dorsi pedicled flap reconstruction, and 2 had tissue expander placement. There were no complete autologous flap losses, and 1 patient underwent tissue expander explantation. Eight of 48 patients (17%) had mastectomy skin flap necrosis of the treated breast, of whom 1 underwent reoperation. During follow-up (median, 29.7 months [range, 10.1-65.2 months]), there were no locoregional recurrences or distant metastasis. This randomized clinical trial found PreMRT and RNI followed by mastectomy and microvascular autologous flap IMBR to be feasible and safe. Based on these results, a larger randomized clinical trial of hypofractionated vs conventionally fractionated PreMRT has been started (NCT05774678). ClinicalTrials.gov Identifier: NCT02912312.

Race and Ethnicity Independently Predict Adverse Outcomes Following Head and Neck Autograft Surgery.

There is growing attention toward the implications of race and ethnicity on health disparities within otolaryngology. While race is an established predictor of adverse head and neck oncologic outcomes, there is paucity in the literature on studies employing national, multi-institutional data to assess the impact of race and ethnicity on head and neck autograft surgery. Using the National Surgical Quality Improvement Program (NSQIP) database, trends in 30 days outcomes were assessed. Patients with ICD-10 codes for malignant head and neck neoplasms were isolated. Autograft surgeries were selected using Current Procedural Terminology (CPT) codes for free flap and pedicled flap reconstruction. Primary outcomes included surgical complications, reoperation, readmission, extended length of stay and operation time. Each binary categorical variable was compared to racial/ethnic identity via binary logistic regression. The study cohort consisted of 2447 patients who underwent head and neck autograft surgery (80.71% free flap reconstruction and 19.39% pedicled flap reconstruction). Black patients had significantly higher odds of overall surgical complications (odds ratio [OR] 1.583, 95% confidence interval [CI] 1.091, 2.298, p = 0.016) with much higher odds of perioperative blood transfusions (OR 2.291, 95% CI 1.532, 3.426, p = <.001). Hispanic patients were more likely to undergo reoperation within 30 days after surgery and were more likely to be hospitalized for more than 30 days post-operatively (OR 1.566, 95% CI 1.015, 2.418, p = 0.043 and OR 12.224, 95% CI 2.698, 55.377, p = 0.001, respectively). Race and ethnicity serve as independent predictors of complications in the post-operative period following head and neck autograft surgery. 3 Laryngoscope, 134:3595-3603, 2024.

Determining Degree of Hypertrophy and Extent of Resection in Aesthetic Labia Minora Reduction: Technical Highlights and Step-by-Step Video Guide.

Advances in aesthetic labia minora (LM) procedures have led to better results and fewer complications. Edge trim or wedge approaches are used, both of which use hidden incisions and preserve the edges of the LM. Since 1998, we have been performing a simple and reliable technique based on inferior wedge LM resection and superior pedicle flap reconstruction. Although details of aesthetic LM reduction have been amply published, previous technical videos have not presented a detailed step-by-step description, and few studies specifically address how to estimate the amount of tissue to resect according to the degree of hypertrophy. This article and the accompanying videos provide a detailed guide that clearly outlines the senior author's (A.M.M.) technique for aesthetic LM reduction. The authors' experience demonstrates that superior pedicle flap reconstruction is a reliable and reproducible technique. The success of the procedure depends on patient selection, careful preoperative planning, and adequate intraoperative management.

Kompleks Abdominal Duvar Defektlerinin Pediküllü Anterolateral Uyluk Flebi ile Onarımı

Introduction: Traumatic abdominal injuries, surgical wound dehiscence, oncologic resections, transplant related complications or abdominal sepsis related visceral edema and abdominal compartment syndrome can cause enormous abdominal defects Abdominal defects are treated differently according to etiology and chronicity, size and thickness of the defect. ALT flap can be used pedicled or as a free flap for abdominal defect reconstruction.&#x0D; &#x0D; Material and methods: Medical records of 8 patients who underwent pedicled ALT flap reconstruction of abdominal defects between August 2019 and November 2020 were retrospectively reviewed Demographic data, flap size, perforator number, complications, hospital stay, use of alloplastic mesh for fascia repair were recorded.&#x0D; &#x0D; Results: 50% of patients received only 1 reconstructive operations while other 50% received more than one (min:2, max:4) operations. Total flap loss was seen at 12.5%. 25% of patients were lost due to non-flap related complications. Mean (min/max) hospital stay was 33,1 (12/90) days.&#x0D; &#x0D; Conclusion: The pedicled ALT flap is a reliable and reproducible flap for reconstruction of abdominal defects without need for microsurgical vessel anastomosis. It has low donor and recipient site morbidity and potential complications can be easily managed with minor secondary operations.

Comparing Fibula Flap Insetting Techniques for Pediatric Oncologic Extremity Reconstruction.

Extremity reconstruction in skeletally immature patients presents unique challenges in terms of operative technique, bone healing, and limb function. A variety of insetting techniques have been described, with no clearly superior option. The authors hypothesized that vascularized fibula flaps placed in the intramedullary space are associated with shorter union times and better functionality compared with onlay flaps. In a cohort study, the authors retrospectively reviewed the medical records of all pediatric patients who underwent fibula flap extremity reconstruction at a single center from 2001 through 2018. Comorbidities, complications, and outcomes were analyzed. Complete fibula union was based on radiographic evidence of significant cortical bridging. Thirty-three patients (mean age, 13.6 years; range, 2 to 18 years) underwent pedicled ( n = 7) or free ( n = 26) fibula flap reconstructions in 12 upper extremities and 21 lower extremities. Median follow-up was 69.5 months (interquartile range, 16.3 to 114.6 months). Onlay and intramedullary fibula position compared with intercalary placement (median, 13.5 and 14.6 months versus 3.4 months; P = 0.002) were associated with longer time to complete bone union. Complications including allograft fracture ( P = 0.02) and hardware removal ( P = 0.018) were also associated with longer time to complete union and eventual conversion to megaprosthesis ( P = 0.02, P = 0.038). Thirty-two patients (97%) achieved full union and a functional reconstruction. Fibula flap reconstruction is safe and effective for pediatric long-bone reconstruction. Longer fibula union times were associated with onlay and intramedullary fibula placement, allograft fracture, and hardware removal. Therapeutic, IV.

Tunneled island pedicle flap reconstruction for upper lateral cutaneous lip defects

Esthetic upper lateral cutaneous lip reconstruction preserves the apical triangle, nasolabial fold symmetry, and free margin position. The tunneled island pedicle flap (IPF) is a novel single-stage reconstruction to achieve these goals. Describe the technique and patient and surgeon-reported outcomes for the tunneled IPF reconstruction of upper lateral cutaneous lip defects. Retrospective chart review of consecutive tunneled IPF reconstruction following Mohs micrographic surgery (MMS) at a tertiary care center between 2014 and 2020. Patients rated their scars using the validated Patient Scar Assessment Scale (PSAS), and independent surgeons rated scars using the validated Observer Scar Assessment Scale (OSAS). Descriptive statistics were generated for patient demographics and tumor defect characteristics. Twenty upper lateral cutaneous lip defects were repaired with the tunneled IPF. Surgeons rated scars with a composite OSAS score of 11.83±4.29 (mean, SD) [scale of 5 (normal skin) to 50 (worst scar imaginable)] and an overall scar score of 2.81±1.11 [scale of 1 (normal skin) to 10 (worst scar imaginable)]. Patients rated their scars with a composite PSAS score of 10±5.39 [scale of 6 (best possible score) to 60 (worst)] and with an overall score of 2.2±1.78 [scale of 1 (normal skin) and 10 (very different from normal skin)]. One flap was surgically revised for pincushioning, but none experienced necrosis, hematoma, or infection. The tunneled IPF is a single-stage reconstruction for upper lateral cutaneous lip defects with favorable scar ratings by patients and observers.

The Utility of a "Second-Look" Debridement Following Endonasal Skull Base Surgery in the Pediatric Population.

Background Sinonasal debridement is typically performed in the weeks following endonasal skull base surgery (ESBS). In the pediatric population, this second-look procedure may require general anesthesia; however, there is currently little evidence assessing the benefit of this practice. Methods This was a multicenter retrospective study of pediatric patients (age <18 years) undergoing a planned second-look debridement under general anesthesia following ESBS. Intraoperative findings, interventions performed, and perioperative complications were reviewed. Multivariate regression analysis was performed to identify associations between intraoperative findings and clinical factors. Results We reviewed 69 cases of second-look debridements (age mean 8.6 ± 4.2 years, range: 2-18 years), occurring a mean of 18.3 ± 10.3 days following ESBS. All abnormal findings were noted in patients age ≤12 years. Synechiae were noted in 8.7% of cases, bacterial rhinosinusitis in 2.9%, and failed reconstruction with cerebrospinal fluid leak in 4.5% (two cases of flap malposition and one case of flap necrosis). All failed reconstructions were noted following expanded endonasal cases for craniopharyngioma, and in each case, a revision reconstruction was performed during the second-look surgery. Synechiae were not significantly associated with younger age, revision cases, or cases with reconstructive flaps. There were no perioperative complications. Conclusion Second-look debridement under general anesthesia may be useful in the identification and intervention of sinonasal pathology following endoscopic skull base surgery, particularly in children ≤12 years old or those with pedicled flap reconstructions. Larger controlled studies are warranted to validate this practice and refine indications and timing of this second procedure.

A Preliminary Experience of Endoscopic Total Mastectomy With Immediate Free Abdominal-Based Perforator Flap Reconstruction Using Minimal Incisions, and Literature Review.

Endoscopic total mastectomy (ETM) is predominantly performed with reconstruction using prostheses, lipofilling, omental flaps, latissimus dorsi flaps, or a combination of these techniques. Common approaches include minimal incisions, e.g., periareolar, inframammary, axillary, or mid-axillary line, which limit the technical ability to perform autologous flap insets and microvascular anastomoses, as such the ETM with free abdominal-based perforator flap reconstruction has not been robustly explored. We studied female patients with breast cancer who underwent ETM and abdominal-based flap reconstruction. Clinical-radiological-pathological characteristics, surgery, complications, recurrence rates, and aesthetic outcomes were reviewed. Twelve patients underwent ETM with abdominal-based flap reconstruction. The mean age was 53.4 years (range 36-65). Of the patients, 33.3% were surgically treated for stage I, 58.4% for stage II, and 8.3% for stage III cancer. Mean tumor size was 35.4 mm (range 1-67). Mean specimen weight was 458.75 g (range 242-800). Of the patients, 92.3% successfully received endoscopic nipple-sparing mastectomy and 7.7% underwent intraoperative conversion to skin-sparing mastectomy after carcinoma was reported on frozen section of the nipple base. Mean operative time for ETM was 139 minutes (92-198), and the average ischemic time was 37.3 minutes (range 22-50). Fifty percent of patients underwent deep inferior epigastric perforator, 33.4% underwent MS-2 transverse rectus abdominis musculocutaneous (TRAM), 8.3% underwent MS-1 TRAM, and 8.3% underwent pedicled TRAM flap reconstruction. No cases required re-exploration, no flap failure occurred, margins were clear, and no skin or nipple-areolar complex ischemia/necrosis developed. In the aesthetic outcome evaluation, 16.7% were excellent, 75% good, 8.3% fair, and none were unsatisfactory. No recurrences were observed. ETM through a minimal-access inferior mammary or mid-axillary line approach, followed by immediate pedicled TRAM or free abdominal-based perforator flap reconstruction, can be a safe means of achieving an "aesthetically scarless" mastectomy and reconstruction through minimal incisions.

Supraclavicular Artery Island Flap in Head-and-neck Reconstruction: Our Experience

Background: Reconstruction of head-and-neck cancer defects is a challenging task, keeping in mind the complexity of the defects. Locoregional pedicle flap reconstruction is not an inferior option. The supraclavicular flap gained popularity in 1997 to reconstruct mentosternal contractures in postburn patients. This is a perforator-based pedicled, axial, and fasciocutaneous flap based on the supraclavicular artery. This study aims to examine a series of cases with pedicled supraclavicular flap reconstruction in head-and-neck cancers. Methods: This study is a retrospective review of patient data from our institution from 2018 to 2020. A total of seven patients were included who underwent surgical resection for various head-and-neck cancers. Surgical defects were reconstructed with a supraclavicular islanded fasciocutaneous flap. Results: All patients underwent wide excision of the tumor following oncological principles, and four out of seven patients received postoperative adjuvant radiotherapy. Two patients with parotid tumors underwent facial skin excision along with total parotidectomy. Both cases were recurrent. One patient had partial necrosis of the distal part of the flap. Two patients required split-thickness skin graft for the closure of the donor site. Conclusion: Supraclavicular artery island flap (SCAIF) is one of the good reconstructive options for midline neck defects, simple oral cavity defects, and cheek skin defects. It is an excellent alternative to free tissue transfer with limited donor-site morbidity. Careful selection of patients is key to successful reconstruction using a SCAIF in the head-and-neck region.
