Reconstruction of an Octogenarian Major Pretibial Degloving Injury Utilizing Negative Pressure Wound Therapy and Subsequently Combining Fenestrated-Type Artificial Dermis Without Skin Grafting.

Major pretibial degloving injuries are complex wounds, which can be challenging to treat. Despite recent advances in reconstructive options, most of these injuries still require a prolonged healing period and may result in amputation. Few reports have been published on the management of these complex traumatic injuries. In this article, we present a case of an octogenarian, frail patient with a major pretibial degloving injury. Treatment included serial surgical debridements in combination with negative pressure wound therapy aimed at salvaging the avulsed tissue. Subsequently, a fenestrated-type artificial dermis and negative pressure wound therapy were used as combined therapy so as to obtain adequate soft tissue coverage. The patient made an unremarkable recovery and was discharged on day 22 after injury. The wound healed by secondary intention without need for skin grafting.

Total shoulder arthroplasty versus reverse total shoulder arthroplasty: Outcome comparison in osteoarthritis patients with or without concurrent rotator cuff deficiency.

Osteoarthritis (OA) is a common shoulder disorder that impacts shoulder functions. Shoulder arthroplasty is often required to restore function and quality of life. Reverse total shoulder arthroplasty (RSA), which was originally designed mainly for irreparable rotator cuff damage, has gained popularity in recent years for the treatment of advanced shoulder OA instead of the clinically standard total shoulder arthroplasty (TSA). However, this RSA has some nonnegligible flaws such as higher complications rate and economic cost, not mention the following problems caused by irreversible physical structural damage. Therefore, the employment of RSA needs to be carefully considered. This study aimed to compare TSA and RSA in OA patients with or without rotator cuff damage to better guide clinical decision making. We believe the radical use of RSA in patients without rotator cuff deficiency may cause more harm than good. We queried the Nationwide Inpatient Sample (NIS) database from 2011 to 2014 to collect information on OA patients who received TSA and RSA. Patients were divided into 2 groups of comparison according to the presence of rotator cuff deficiency and matched with propensity score analysis. A total of 57,156 shoulder arthroplasties were identified. RSA patients in the rotator cuff deficiency group had significant higher transfusion rates and longer hospital stays. RSA patients without rotator cuff deficiency had a statistically significantly higher number of implant-related mechanical complications, acute upper respiratory infections and postoperative pain. Overall, RSA incurred higher costs in both groups. For OA patients with rotator cuff deficiencies, RSA has its benefits as complication rates were comparable to TSA. For those patients without rotator cuff deficiencies, the use of RSA should be reconsidered as there were more complications with higher severity.

Negative-Pressure Wound Therapy in the Prevention and Management of Complications From Prosthetic Breast Reconstruction: A Systematic Review and Meta-analysis.

BACKGROUND: Complications from prosthetic breast reconstruction are distressing for patients, and their management is challenging. For decades, negative-pressure wound therapy (NPWT) has been successfully used for the closure of complex wounds. This study analyzes the outcomes of NPWT use in the prevention and management of complications from prosthetic breast reconstruction. METHOD: A systematic search of studies published until August 2020 was conducted using the PubMed/MEDLINE, EMBASE, and Ebscohost/CINAHL databases and using the following key words: "negative-pressure wound therapy," "breast reconstruction," and "prosthesis" (including breast implants and tissue expanders). Analyzed endpoints were outcomes of NPWT use in prosthetic breast reconstruction compared with conventional dressings. The methodological quality of included studies was assessed independently. Comparative studies were further meta-analyzed to obtain pooled odds ratios (ORs) describing the effectiveness of NPWT in prosthetic breast reconstruction. RESULTS/DISCUSSION: Ten studies were included with a total of 787 patients (1230 breasts) undergoing prosthetic breast reconstruction with breast implants or tissue expanders. Three case-control studies focused on preventing breast wound complications. The meta-analysis of the 3 studies included 502 breasts receiving NPWT and 698 breasts receiving conventional wound care. The meta-analysis favored NPWT for less mastectomy flap necrosis (5.6% vs 14.3%; OR, 0.46; 95% confidence interval, 0.27 -0.77; P = 0.004; I2 = 0%) and less overall wound complications (10.6% vs 21.1%; OR, 0.49; 95% confidence interval, 0.35-0.70; P < 0.00001; I2 = 0%). In the management of nipple-areolar complex venous congestion, 1 case report demonstrated 85% rescue of nipple-areolar complex after using NPWT (-75 mm Hg) for a total of 12 days. In the management of periprosthetic infections, 2 case series used NPWT with instillation. It accelerated the treatment of infection and maintained the breast cavity for future reconstruction. Conventional NPWT also showed good salvage outcome in four studies. CONCLUSIONS: Current evidence suggests that prophylactic use of NPWT in prosthetic breast reconstruction reduces the rate of overall wound complications and mastectomy flap necrosis. In the management of complications from prosthetic breast reconstructions, NPWT may be a promising option showing beneficial results. Additional high-quality trials are warranted to corroborate the findings of this systematic review.

Mortality Within 30 Days After Head and Neck Free Flap Reconstruction: A Systematic Review.

OBJECTIVE: The aim of this systematic review is to analyze the 30-day postoperative mortality in patients undergoing free flap reconstruction for head and neck cancer published in literature and to identify associated factors. METHODS: The authors performed a literature search between January 1950 and February 2020 in PubMed, EMBASE, and Scopus, using a combination of Medical Subject Headings headings and text keywords related to head and neck cancer; microsurgery or free flap reconstruction; and 30-day mortality. Inclusion criteria were: original studies in English reporting on 30-day mortality after head and neck free flap reconstruction in adult population. RESULTS: Thirty-one publications reported on a total of 13,447 patients who underwent head and neck free flap reconstruction. The published 30-day postoperative mortality ranged from 0% to 6.3%, with an average of 1.21%. A number of studies examined the association between mortality and body mass index, American Society of Anesthesiologists, and comorbidity score and age. One study found that underweight patients had significantly higher mortality. Two studies found no association between the American Society of Anesthesiologists score and 30-day postoperative mortality; however, 1 study reported significantly higher mortality with increased comorbidity score. Regarding association with age, 3 studies found significant higher mortality in older patients, while 5 studies found no difference. CONCLUSIONS: The average 30-day postoperative mortality in patients undergoing head and neck free flap reconstruction is 1.21% and is; therefore, not negligible. Careful patient selection and preoperative optimization are essential in order to reduce mortality in head neck free flap reconstruction.

TGF-ß loaded exosome enhances ischemic wound healing in vitro and in vivo.

Rationale: With over seven million infections and $25 billion treatment cost, chronic ischemic wounds are one of the most serious complications in the United States. The controlled release of bioactive factor enriched exosome from finbrin gel was a promising strategy to promote wound healing. Methods: To address this unsolved problem, we developed clinical-grade platelets exosome product (PEP), which was incorporate with injectable surgical fibrin sealant (TISSEEL), to promote chronic wound healing and complete skin regeneration. The PEP characterization stimulated cellular activities and in vivo rabbit ischemic wound healing capacity of TISSEEL-PEP were performed and analyzed. Results: PEP, enriched with transforming growth factor beta (TGF-ß), possessed exosomal characteristics including exosome size, morphology, and typical markers including CD63, CD9, and ALG-2-interacting protein X (Alix). In vitro, PEP significantly promoted cell proliferation, migration, tube formation, as well as skin organoid formation. Topical treatment of ischemic wounds with TISSEEL-PEP promoted full-thickness healing with the reacquisition of hair follicles and sebaceous glands. Superior to untreated and TISSEEL-only treated controls, TISSEEL-PEP drove cutaneous healing associated with collagen synthesis and restoration of dermal architecture. Furthermore, PEP promoted epithelial and vascular cell activity enhancing angiogenesis to restore blood flow and mature skin function. Transcriptome deconvolution of TISSEEL-PEP versus TISSEEL-only treated wounds prioritized regenerative pathways encompassing neovascularization, matrix remodeling and tissue growth. Conclusion: This room-temperature stable, lyophilized exosome product is thus capable of delivering a bioactive transforming growth factor beta to drive regenerative events.

Neurotized free VRAM used to create myoelectric signals in a muscle-depleted area for targeted muscle reinnervation for intuitive prosthesis control: A case report.

Targeted muscle reinnervation enables native muscles to send electromyographic signals to myoelectric receptors, which drive movements in a prosthesis. This system requires voluntary contracture of muscles for sequential control of powered prosthetic joints. This report describes a surgical solution for cases where the chest wall is depleted of muscle targets. A 13-year-old boy with left forequarter amputation and pectoralis major resection as a result of extended necrotizing facilities 8 years prior received a neurotized free Vertical Rectus Abdominus Mycocutaneous (VRAM) flap (28 × 10 cm) designed to produce myoelectric signals, reduce pain, and provide stability for prosthetic fitting. Five intercostal nerves from the VRAM were coapted to portions of the brachial plexus to create a myoelectric interface for targeted muscle reinnervation. The postoperative course was uneventful. At 39 months of follow-up, the patient gained control of the transferred VRAM and was able to operate a custom-fitted myoelectric prosthesis together with contraction of the ipsilateral infraspinatus muscle. The neurotized VRAM transfer created a neural interface in an area with depleted neuromuscular targets while decreasing pain and adding tissue bulk for proper prosthesis fitting. Such a surgical strategy may have applications in other areas of the body.

Intrinsic Tendon Regeneration After Application of Purified Exosome Product: An In Vivo Study.

BACKGROUND: Tendons are primarily acellular, limiting their intrinsic regenerative capabilities. This limited regenerative potential contributes to delayed healing, rupture, and adhesion formation after tendon injury. PURPOSE: To determine if a tendon's intrinsic regenerative potential could be improved after the application of a purified exosome product (PEP) when loaded onto a collagen scaffold. STUDY DESIGN: Controlled laboratory study. METHODS: An in vivo rabbit Achilles tendon model was used and consisted of 3 groups: (1) Achilles tenotomy with suture repair, (2) Achilles tenotomy with suture repair and collagen scaffold, and (3) Achilles tenotomy with suture repair and collagen scaffold loaded with PEP at 1 × 1012 exosomes/mL. Each group consisted of 15 rabbits for a total of 45 specimens. Mechanical and histologic analyses were performed at both 3 and 6 weeks. RESULTS: The load to failure and ultimate tensile stress were found to be similar across all groups (P ≥ .15). The tendon cross-sectional area was significantly smaller for tendons treated with PEP compared with the control groups at 6 weeks, which was primarily related to an absence of external adhesions (P = .04). Histologic analysis confirmed these findings, demonstrating significantly lower adhesion grade both macroscopically (P = .0006) and microscopically (P = .0062) when tendons were treated with PEP. Immunohistochemical staining showed a greater intensity for type 1 collagen for PEP-treated tendons compared with collagen-only or control tendons. CONCLUSION: Mechanical and histologic results suggested that healing in the PEP-treated group favored intrinsic healing (absence of adhesions) while control animals and animals treated with collagen only healed primarily via extrinsic scar formation. Despite a smaller cross-sectional area, treated tendons had the same ultimate tensile stress. This pilot investigation shows promise for PEP as a means of effectively treating tendon injuries and enhancing intrinsic healing. CLINICAL RELEVANCE: The production of a cell-free, off-the-shelf product that can promote tendon regeneration would provide a viable solution for physicians and patients to enhance tendon healing and decrease adhesions as well as shorten the time required to return to work or sports.

Modified Use of Costal Cartilage in Asians for the Correction of Nostril Asymmetry in Unilateral Secondary Cleft Lip Nasal Deformity.

BACKGROUND: Weak alar cartilage and lack of soft tissue on the cleft side are considered to be the main critical factors leading to the asymmetry of bilateral nostrils. The costal cartilage can provide strong structural support and can be used to maintain long-term stability of nostril shape after surgical correction. With the advancement in rhinoplasty techniques, the application and understanding of costal cartilage in cleft lip nasal deformity is still on going. Herein, we present our technique of applying costal cartilage to provide nostril support and correct asymmetry in Asian patients with unilateral secondary cleft lip nasal deformity. METHODS: Ninety-seven patients who underwent nostril asymmetry correction from January 1, 2013, to October 31, 2018, were analyzed retrospectively. Modified integrative alar cartilage strut and diced nostril augmentation with costal cartilage were implemented to improve the collapsed and flat cleft-side nostril. The release and restoration of muscle and bone were also performed when required. Surgical outcomes were analyzed based on the comparison of nostril parameters, the shape and contour, and symmetry of bilateral nostrils after surgery. During postoperative follow-up, the patients' satisfactions with the corrective outcomes were also investigated. RESULTS: All patients received the corrective operations with complete survival of all implanted cartilages. The nostril width was narrower in postoperative group (P < 0.05). The nostril height and long axis angle were higher postoperatively (P < 0.05). After correction, the proportion of moderate type increased from 13.4% to 80.4%, whereas the proportion of horizontal type decreased from 86.6% to 17.5%. The symmetry score on the nostril parameters manifested the rate of high score (AS >3) in postoperative groups were 84.5%, 93.8%, and 87.6% for width, height, and angle of the long axis, respectively. They were higher compared with those of preoperative group (0%). More than 95% of the patients were satisfied with the overall aesthetic outcome of the surgery. CONCLUSIONS: Through ameliorating its constructive technology and optimizing its filling form, the modified use of costal cartilage displayed excellent correction effects in the width, height, and long axis angle asymmetry of Asian patients' nostril. Precise and comprehensive rhinoplasty technique is the cornerstone for achieving satisfactory long-term aesthetic outcomes, especially in severe cases, such as secondary cleft lip nasal deformity.

Repair of severe traumatic nasal alar defects with combined pedicled flap and conchal cartilage composite grafts: a retrospective study.

BACKGROUND: Repair of traumatic alar defect is challenging because poor blood supply is caused by contracture scars, which sometimes extend beyond the alar groove. However, few studies have investigated the reconstruction results of severe traumatic cases. This study aimed to examine the clinical outcomes of severe traumatic alar defect reconstruction using either pedicled nasolabial or forehead flaps combined with conchal cartilage. METHODS: This retrospective study investigated the clinical characteristics and treatment effects of 17 patients with severe traumatic alar defects treated in a single plastic surgery center from March 1, 2015, to September 1, 2018. All cases were scored and graded with regard to the size and depth of the alar defect and the surrounding scar according to the Alar Defect Severity Score (ADSS). Surgical outcomes were evaluated on the basis of the severity of defect before repair, donor site distortion, and postoperative nasal symmetry, especially shape and color. RESULTS: The average ADSS of the cases was 8.1±0.8 (highest score, 9.0). No flap necrosis or any complications were observed postoperatively. The symmetry of the bilateral alae was satisfactory. No color distinction between grafts and surrounding tissues, retraction, or inferior displacement of the ala was observed at an average follow-up of 24.2±10.4 months (range, 8-42 months). The average postoperative surgeon-based evaluation score was 4.3±0.2 (highest score, 5.0). Esthetic and functional results were satisfactory in all cases. CONCLUSIONS: A pedicled flap combined with conchal composite grafts should be considered for the treatment of severe traumatic alar defect. This is a reproducible technique that enables a predictably decent outcome for severe traumatic alar defect, especially in Asian patients.

Single-stage VASER-assisted liposuction and lymphatico-venous anastomoses for the treatment of extremity lymphedema: a case series and systematic review of the literature.

BACKGROUND: A paradigm shift towards the use of combined physiological and excisional surgical approaches for the treatment of lymphedema is permeating the surgical practice worldwide. We describe a single-stage surgical approach combining-vaser assisted liposuction (VAL) and lymphatico-venous anastomoses (LVA) for the treatment of extremity-lymphedema. METHODS: Between March 2018 and March 2019, a retrospective review of patients with extremity-lymphedema stage IIb-III International Society of Lymphology who underwent the combined technique was done. Demographics, operative characteristics, clinical outcomes and complications were assessed. Additionally, a systematic review of studies that reported combined physiological procedures with liposuction for the treatment of lymphedema was conducted. RESULTS: A total of 24 patients [12 upper extremity lymphedema (UEL), and 12 lower extremity lymphedema (LEL)] were included and analyzed. The mean age was 54.5 years (38-72 years). The mean circumference reduction rate was 90% and 85% for UEL and LEL, respectively. Infection rate decreased to zero postoperatively in all patients. Ten studies were included in the review: six pooling 220 cases included two-stage procedures, and four pooling 66 cases described one-stage surgeries. All patients who underwent a combined approach reported clinical improvement. CONCLUSIONS: Our combined approach is safe surgical option and allows adequate limb size reduction with faster recovery in selected patients with lymphedema with strong fibroadipose component.

Prepectoral Two-Stage Implant-Based Breast Reconstruction with and without Acellular Dermal Matrix: Do We See a Difference?

BACKGROUND: Prepectoral implant-based breast reconstruction has gained popularity because of advantages over the subpectoral technique. Acellular dermal matrix use with implant-based breast reconstruction has become common because of its perceived superior aesthetic outcome. Matrices are expensive, however, and recent evidence has pointed to several potential complications. This article reports a series of prepectoral implant-based breast reconstructions with and without acellular dermal matrix and compared their outcomes. METHODS: This is a single-surgeon retrospective review of patients who underwent staged prepectoral implant-based breast reconstruction following nipple-sparing mastectomy over two periods. Patients with well-perfused mastectomy skin flaps with a homogeneous thickness underwent reconstruction with acellular dermal matrix initially. On evolution of the practice, it was not used. Patient demographics, operative data, and complications were analyzed. Aesthetic outcome was measured by the BREAST-Q survey and the Aesthetic Item Scale. A cost analysis was also performed. RESULTS: Forty patients were included (acellular dermal matrix group, n = 19; non-acellular dermal matrix group, n = 21). The nonmatrix group had one case (5 percent) of seroma and one case (5 percent) with hematoma; there were none in the acellular dermal matrix group. Average BREAST-Q and Aesthetic Item Scale scores were 82.3 versus 81.6 (p = 0.954) and 20.98 versus 20.43 (p = 0.640) for the matrix and nonmatrix groups, respectively. The direct cost savings for the authors' institution over 1 year if matrix was not used in all cases of implant-based breast reconstruction would be estimated at $3,105,960 to $6,211,920 for unilateral and bilateral cases, respectively, for Medicare reimbursement. CONCLUSIONS: With adequate patient selection, acellular dermal matrix is not always required during two-stage prepectoral implant-based breast reconstruction for good aesthetic outcomes. The economic burden on patients and the health care system could be lessened with selective matrix use. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, III.

Combined double vascularized lymph node transfers and modified radical reduction with preservation of perforators for advanced stages of lymphedema.

BACKGROUND: Treatment of advanced lymphedema requires not only restoration of physiological lymph drainage, but also excision of fibrotic tissue and excess skin. The aim of this study is to show how the combination of double vascularized lymph node transfers (VLNTs) and a modified radical reduction with preservation of perforators (RRPP) can accomplish both of these treatment goals. METHODS: Between 2010 and 2016, 16 patients (15 female and one male) with extremity lymphedema underwent a combined double gastroepiploic VLNTs and modified RRPP. Demographics, outcomes including circumference reduction rates, preoperative and postoperative lymphoscintigraphy, complications, and responses to the Lymphedema Quality of Life (LYMQOL) questionnaire were analyzed. RESULTS: All flaps survived. The mean follow-up period was 14.2 months (range, 12-19). The mean circumference reduction rate was 74.5% ± 6.9% for the upper limb and 68.0% ± 4.2% for the lower limb. There were no major complications. Minor complications, including numbness and hyperesthesia, were treated conservatively. LYMQOL showed a 2.7-fold quality-of-life improvement (P < 0.01). Postoperative lymphoscintigraphy showed improved lymphatic drainage in all cases. CONCLUSION: Combined double VLNTs and modified RRPP safely and effectively improves lymphatic drainage, reduces fibrotic tissue and excess skin, decreases episodes of infections, and improves patients' quality of life in the advanced stages of lymphedema.

Ileocecal vascularized lymph node transfer for the treatment of extremity lymphedema: A case report.

Vascularized lymph node (VLN) transfer has been of high interest in the past decade for the treatment of lymphedema, since it has been shown to be effective in reducing limb volumes, decreasing infectious episodes and improving quality of life. Multiple donor sites have been described in the quest for the optimal one. Herein, we describe a novel lymph node flap option based on the ileocolic artery and vein. The ileocecal vascularized lymph node (IC-VLN) flap was used in the management of a 33-year-old male patient with lower extremity lymphedema secondary to left inguinal trauma. The patient had previously underwent a pedicled omentum flap transposition with minimal improvement in limb size and persistent episodes of infection. At 15 month follow-up, the IC-VLN flap improved the lymphatic drainage in the affected limb with a mean limb circumference reduction rate of 26.3%. No donor site complications or further episodes of infection were noted. According to our findings, the IC-VLN flap may be another option for VLN transfer in very selected cases. Nevertheless, larger series with a longer follow-up are required to analyze the efficacy and long-term results of this flap.

Assessment of Pelvic Floor Anatomy for Male-to-Female Vaginoplasty and the Role of Physical Therapy on Functional and Patient-Reported Outcomes.

BACKGROUND: Rapid increase in number of male-to-female vaginoplasties emphasizes the need for preoperative measures to optimize final surgical and patient-reported outcomes. Hormonal therapy and socioeconomic factors may contribute to a higher incidence of pelvic floor dysfunction in patients undergoing male-to-female vaginoplasty. The purpose of this study was to evaluate the incidence of pelvic floor dysfunction in this population and the role of physical therapy in its treatment. METHODS: From July 2016 to July 2018, patients scheduled to undergo male-to-female vaginoplasty were evaluated by a physical therapist for pelvic floor dysfunction. Patient charts were reviewed for demographics, comorbidities, and length of hormonal therapy. Those with and without symptoms were compared. Symptomatic patients underwent therapy. Assessment of symptom severity and its impact on daily living were completed at 2- to 3-month intervals with physical therapy using the 6-item Urinary Distress Index 6 and 8-item Colorectal Anal Distress Index components of the 20-item Pelvic Floor Distress Inventory (PFDI-20) before and after surgery. A third component of the PFDI-20, the 6-item Pelvic Organ Prolapse Distress Inventory, was also included in the postoperative assessment. RESULTS: Over a 24-month period, a total of 40 patients with a mean age of 40.7 (19-72) years and body mass index of 27.1 kg/m (22-39 kg/m) were enrolled. Comorbidities included 4 patients (10%) with diabetes and 6 patients (15%) with hypertension. Patients with symptoms had a significantly higher mean age (P < 0.01). Only 1 patient (2.5%) had new-onset pelvic floor dysfunction after surgery, and there was no significant increase in severity of symptoms in those with a previous pelvic floor dysfunction postoperatively. Physical therapy significantly (P < 0.01) reduced severity of symptoms and its impact on daily living as assessed by the Urinary Distress Index and Colorectal Anal Distress Index before and after surgery and by the PFDI-20 and 7-item Pelvic Floor Dysfunction Index postoperatively. CONCLUSIONS: A high incidence of pelvic floor dysfunction may exist in patients undergoing male-to-female vaginoplasty preoperatively. Screening at this early stage with both preoperative and postoperative therapy can significantly reduce pelvic floor dysfunction and improve symptoms and quality of life for this population.

Optimizing survival of large fibula osteocutaneous flaps for extensive full-thickness oromandibular defects: A two-stage approach with temporary orocutaneous fistula.

INTRODUCTION: Composite and large head and neck defects requiring extensive skin-mucosa coverage are often reconstructed by combining flaps. Herein, we present a simple and reliable two-stage fibula osteocutaneous (FOC) flap technique to improve the survival of a large skin paddle for oromandibular reconstructions. METHODS: From October 2011 to September 2016, 47 patients with through-and-through oromandibular defects were reconstructed using FOC flaps with large skin paddles. To ensure optimum survival of skin paddles, temporary orocutaneous fistula were left in place and closed during the second stage operation via de-epithelialization of the skin paddle and suturing of mucosa. Demographic data, operative details, and postoperative complications were recorded. RESULTS: The skin paddle dimensions ranged from 20 to 31.5 cm in length and 12 to 17 cm in width with an average area of 430.4 cm2 (range 300-504). The average time between the two stages and hospital stay were 10 days and 14 days, respectively. Complications at the donor site included wound dehiscence (n = 3, 6.4%), partial skin graft loss (n = 3, 6.4%) and hematoma (n = 2, 4.3%). Recipient site complications included two (4.3%) early postoperative venous congestions that resolved after elevation and three (6.4%) partial skin flap necrosis (less than 5% surface area). All complications resolved with bedside conservative management. There was only one take-back for evacuation of recipient site hematoma (2.1%) but no flap loss. CONCLUSION: Two-staged large skin paddle FOC flaps can simplify reconstruction of extensive oromandibular defects by improving the reliability of the sizable skin paddle and negating the need for a second flap.

Utilization of Anterolateral Thigh Flap and Transverse Cervical Recipient Vessels for Head and Neck Cancer Patients With Former Neck Dissection and Irradiation: A Case Series Study.

PURPOSE: Free flap reconstruction in head and neck cancer patients with prior tumor resection, neck dissection, and irradiation is clinically challenging. The purpose of this study was to investigate the reliability and outcome of using the anterolateral thigh (ALT) flap and transverse cervical recipient vessels for microvascular reconstruction in patients with depleted vessels in the head and neck region caused by previous surgery and irradiation. METHODS: Between January 2015 and December 2017, microsurgical head and neck reconstruction was performed using the ALT flap and transverse cervical artery (TCA) as the recipient vessel in 15 patients who had undergone previous neck dissections and irradiation for cancer treatment. All patients had a "vessel-depleted neck" resulting from severe scarring and radiation fibrosis. Clinical data of each patient were recorded. RESULTS: All ipsilateral TCAs were found to be damage free. Subsequently, free ALT flaps were revascularized using the TCAs. One patient developed venous thrombosis, and another patient developed arterial thrombosis. They were both salvaged within 6 hours postoperatively. No flap failure or mortalities were reported within the 30-day postoperative period. Two patients developed orocutaneous fistula and were further managed with wound care. The mean follow-up time was 11.9 ± 6.0 months (range, 5-23 months). Five patients died during the follow-up period from cancer progression. CONCLUSIONS: The use of the free ALT flap and TCA as the recipient vessel provides favorable microsurgical outcomes in patients with depleted recipient vessels in the head and neck region caused by previous neck dissections and radiation therapy.

Expanding the applications of the combined transverse upper gracilis and profunda artery perforator (TUGPAP) flap for extensive defects.

BACKGROUND: The medial thigh is a well-hidden area. The two most common flaps from this area are the transverse upper gracilis (TUG) and profunda artery perforator (PAP) flaps. Herein, we explored the applications of combined TUGPAP flap to reconstruct large and complex defects in different regions. METHODS: Between November 2015 and May 2017, 28 patients who underwent reconstruction and extensive soft tissue coverage with the TUGPAP flap for the breasts, head and neck, and pelvi-perineal regions were included. The defects size ranged from 22 to 29 × 6-8 cm. All flaps were based on the two pedicles: the medial circumflex femoral artery for TUG flap and the profunda artery perforator for PAP flap. They were each anastomosed to a set of recipient vessels. A "Y"-shaped interposition vein graft (YVG) was used if only one recipient artery was available. RESULTS: The harvested skin paddle had dimensions ranged from 20 to 30 × 6-9 cm and all flaps survived completely. Postoperative complications included one case each of donor and recipient site seroma, and one case of wound dehiscence. They were all successfully managed conservatively. During an average follow-up period of 12.7 months, one patient reported permanent paresthesia in the donor site and another developed hypertrophic scar. All patients were able to resume daily activity without major concerns. CONCLUSION: The combined TUGPAP flap is a safe, effective, and a good alternative to the common workhorse flaps as it offers the potential for a large skin paddle and decent soft tissue volume with low donor site morbidity in a well-concealed area.
