Increased access to care and insurance coverage has led to an increase in gender-affirming surgeries performed in the United States. Gender-affirming phalloplasty has a variety of donor sites and surgical techniques including both pedicled and free flaps. Although surgical techniques and patient outcomes are well-described, no reports in the literature specifically discuss postoperative management, which plays a crucial role in the success of these operations. Here, we present a postoperative protocol based on our institution's experience with gender-affirming phalloplasty with the hope it will serve as a standardized, reproducible reference for centers looking to offer these procedures.

BACKGROUND:Vascularized composite allotransplantation (VCA) has redefined the frontiers of plastic and reconstructive surgery. At the cutting edge of this evolving paradigm, we present the first successful combined full face and bilateral hand transplant (FT-BHT). METHODS:A 21-year-old man with sequelae of an 80% total body surface area burn injury sustained following a motor vehicle accident presented for evaluation. The injury included full face and bilateral upper extremity composite tissue defects, resulting in reduced quality of life and loss of independence. Multidisciplinary evaluation confirmed eligibility for combined FT-BHT. The operative approach was validated through 11 cadaveric rehearsals utilizing computerized surgical planning. Institutional review board and organ procurement organization approvals were obtained. The recipient, his caregiver, and the donor family consented to the procedure. RESULTS:Combined full face (eyelids, ears, nose, lips, and skeletal subunits) and bilateral hand transplantation (forearm level) was performed over 23 hours on August 12-13th, 2020. Triple induction and maintenance immunosuppressive therapy and infection prophylaxis were administered. Plasmapheresis was necessary postoperatively. Minor revisions were performed over seven subsequent operations, including five left upper extremity, seven right upper extremity, and seven facial secondary procedures. At eight months, the patient is approaching functional independence and remains free of acute rejection. He has significantly improved range of motion, motor power, and sensation of the face and hand allografts. CONCLUSION/CONCLUSIONS:Combined FT-BHT is feasible. This is the most comprehensive VCA procedure successfully performed to date, marking a new milestone in plastic and reconstructive surgery for patients with otherwise irremediable injuries.

ABSTRACT/UNASSIGNED:Venous congestion accounts for most microvascular free tissue flaps failures. Given the lack of consensus on the use of single versus dual venous outflow, the authors present our institutional experience with 1 versus 2 vein anastomoses in microvascular free flap for head and neck reconstruction. A retrospective chart review was performed on all patients undergoing free flaps for head and neck reconstruction at our institution between 2008 and 2020. The authors included patients who underwent anterolateral thigh, radial forearm free flap, or fibula free flaps. The authors classified patients based on the number of venous anastomoses used and compared complication rates. A total of 279 patients with a mean age of 55.11 years (standard deviation 19.31) were included. One hundred sixty-eight patients (60.2%) underwent fibula free flaps, 59 (21.1%) anterolateral thigh, and 52 (18.6%) radial forearm free flap. The majority of patients were American Society of Anesthesiologists classification III or higher (N = 158, 56.6%) and had history of radiation (N = 156, 55.9%). Most flaps were performed using a single venous anastomosis (83.8%). Univariate analysis of postoperative outcomes demonstrated no significant differences in overall complications (P = 0.788), flap failure (P = 1.0), return to the Operating Room (OR) (P = 1.0), hematoma (P = 0.225), length of hospital stay (P = 0.725), or venous congestion (P = 0.479). In our cohort, the rate of venous congestion was not statistically different between flaps with 1 and 2 venous anastomoses. Decision to perform a second venous anastomoses should be guided by anatomical location, vessel lie, flap size, and intraoperative visual assessment.

BACKGROUND:Moyamoya disease may present with either hemorrhagic or ischemic strokes. Surgical bypass has previously demonstrated superiority when compared to natural history and medical treatment alone. The best bypass option (direct vs. indirect), however, remains controversial in regard to adult ischemic symptomatic moyamoya disease. Multiple studies have demonstrated clinical as well as angiographic effectiveness of direct bypass in adult hemorrhagic moyamoya disease. In particular, there are limited data regarding strategies in the setting of failed indirect bypass with recurrent hemorrhagic strokes. Here, we describe a salvage procedure. METHODS:We describe a case of a 52-year-old man who presented with hemorrhagic moyamoya disease and failed previous bilateral encephaloduroarteriosynangiosis (EDAS) procedures at an outside institution. On a 3-year follow-up diagnostic cerebral angiogram, no synangiosis was noted on the right side and only minimal synangiosis was present on the left. The left hemisphere was significant for a left parietal hypoperfusion state. We performed a salvage left proximal superficial temporal artery to distal parietal M4 middle cerebral artery bypass using the descending branch of the lateral circumflex artery as an interposition graft with preservation of the existing EDAS sites. RESULTS:The patient underwent the procedure successfully and recovered well with resolution of headaches and no further strokes or hemorrhages on the 1-year follow-up magnetic resonance imaging of the brain. CONCLUSIONS:This case presents the use of a salvage direct bypass technique for recurrent symptomatic hemorrhagic moyamoya disease after failed EDAS. The strategy, approach, and technical nuances of this unique case have implications for revascularization options.

INTRODUCTION/BACKGROUND:The coronavirus disease-19 (COVID-19) pandemic dramatically changed the delivery of breast cancer care. The objective of this study was to quantify the effect of the pandemic on breast cancer screening, treatment, and reconstruction at a single institution in New York City. METHODS:A retrospective chart review was conducted to determine the number of mammograms, lumpectomies, mastectomies, and breast reconstruction operations performed between January 1, 2019 and June 30, 2021. Outcomes analyzed included changes in mammography, oncologic surgery, and breast reconstruction surgery volume before, during and after the start of the pandemic. RESULTS:Mammography volume declined by 11% in March-May of 2020. Oncologic breast surgeries and reconstructive surgeries similarly declined by 6.8% and 11%, respectively, in 2020 compared with 2019, reaching their lowest levels in April 2020. The volume of all procedures increased during the summer of 2020. Mammography volumes in June and July 2020 were found to be at pre-COVID levels, and in October-December 2020 were 15% higher than in 2019. Oncologic breast surgeries saw a similar rebound in May 2020, with 24.6% more cases performed compared with May 2019. Breast reconstruction volumes increased, though changes in the types of reconstruction were noted. Oncoplastic closures were more common during the pandemic, while two-stage implant reconstruction and immediate autologous reconstruction decreased by 27% and 43%, respectively. All procedures are on track to increase in volume in 2021 compared to that in 2020. CONCLUSION/CONCLUSIONS:The COVID-19 pandemic reduced the volume of breast cancer surveillance, surgical treatment, and reconstruction procedures. While it is reassuring that volumes have rebounded in 2021, efforts must be made to emphasize screening and treatment procedures in the face of subsequent surges, such as that recently attributable to the Delta and Omicron variants.

BACKGROUND:Computerized surgical planning (CSP) in osseous reconstruction of head and neck cancer defects has become a mainstay of treatment. However, the consequences of CSP-designed titanium plating systems on planning adjuvant radiation remains unclear. METHODS:Two patients underwent head and neck cancer resection and maxillomandibular free fibula flap reconstruction with CSP-designed plates and immediate placement of osseointegrated dental implants. Surgical treatment was followed by adjuvant intensity modulated radiation therapy (IMRT). RESULTS:Both patients developed osteoradionecrosis (ORN), and one patient had local recurrence. The locations of disease occurred at the areas of highest titanium plate burden, possibly attributed to IMRT dosing inaccuracy caused by the CSP-designed plating system. CONCLUSION/CONCLUSIONS:Despite proven benefits of CSP-designed plates in osseous free flap reconstruction, there may be an underreported risk to adjuvant IMRT treatment planning leading to ORN and/or local recurrence. Future study should investigate alternative plating methods and materials to mitigate this debilitating outcome.

INTRODUCTION/BACKGROUND:Reducing donor site morbidity after deep inferior epigastric artery perforator (DIEP) flap harvest relies mainly upon maintaining integrity of the anterior rectus sheath fascia. The purpose of this study is to describe our minimally-invasive technique for robotic DIEP flap harvest. METHODS:), respectively. Average follow-up was 6.31 months (range: 5.73-7.27 months). Robotic flap harvest was performed with intramuscular perforator dissection in standard fashion, followed by the transabdominal preperitoneal (TAPP) approach to DIEP pedicle harvest using the da Vinci Xi robot. Data was collected on demographic information, perioperative characteristics. Primary outcomes included successful flap harvest as well as donor site morbidity (e.g., abdominal bulge, hernia, bowel obstruction, etc.). RESULTS:All four patients underwent bilateral abdominally-based free flap reconstruction. Three patients received bilateral robotic DIEP flaps, and one patient underwent unilateral robotic DIEP flap reconstruction. The da Vinci Xi robot was used in all cases. Average flap weight and pedicle length were 522 g (range: 110-809 g) and 11.2 cm (range: 10-12 cm), respectively. There were no flap failures, and no patient experienced abdominal wall donor site morbidity on physical exam. CONCLUSION/CONCLUSIONS:While further studies are needed to validate its use, this report represents the largest series of robotic DIEP flap harvests to date and is a valuable addition to the literature.

The method of skin closure and post-operative wound management has always been important in orthopedic surgery and plays an even larger role now that surgical site infection (SSI) is a national healthcare metric for both surgeons and hospitals. Wound related issues remain some of the most feared complications following orthopedic trauma procedures and are associated with significant morbidity. In order to minimize the risk of surgical site complications, surgeons must be familiar with the physiology of wound healing as well as the patient and surgical factors affecting healing potential. The goal of all skin closure techniques is to promote rapid healing with acceptable cosmesis, all while minimizing risk of infection and dehiscence. Knowledge of the types of closure material, techniques of wound closure, surgical dressings, negative pressure wound therapy, and other local modalities is important to optimize wound healing. There is no consensus in the literature as to which closure method is superior but the available data can be used to make informed choices. Although often left to less experienced members of the surgical team, the process of wound closure and dressing the wound should not be an afterthought, and instead must be part of the surgical plan. Wounds that are in direct communication with bony fractures are particularly at risk due to local tissue trauma, resultant swelling, hematoma formation, and injured vasculature.

Silber and Kelly first described the successful autotransplantation of an intra-abdominal testis in 1976. Subsequent authors incorporated laparoscopy and demonstrated the viability of transplanted testes based on serial postoperative exams. We sought to extend this experience with use of the da Vinci surgical robot, thereby demonstrating a novel robotic technique for the management of cryptorchidism. The procedure was performed for an 18-year-old male with a solitary left intra-abdominal testis. Following establishment of pneumoperitoneum, the robot is docked with four trocars oriented towards the left lower quadrant. Testicular dissection is carried out as shown. The gonadal and inferior epigastric vessels are isolated and mobilized; once adequate length is achieved, the former is clipped and transected, and the testicle and inferior epigastric vessels are delivered out of the body. The robot is then undocked and exchanged for the operating microscope. Arterial and venous anastomoses are completed with interrupted and running 9-0 Nylon, respectively, and satisfactory re-anastomosis is confirmed visually and with Doppler. The transplanted testicle is then fixed inferiorly and laterally within the left hemiscrotum, and all incisions are closed. We note that intraoperative testicular biopsy was not performed, for three reasons: (1) to avoid further risk to an already tenuous, solitary organ, (2) because our primary aim was to preserve testicular endocrine function, and (3) because the presence of ITGCN would neither prompt orchiectomy nor obviate the need for ongoing surveillance via periodic self-examination and ultrasonography. The patient is maintained on bed rest for two days and discharged on postoperative day seven in good condition. Over one year since autotransplantation, his now intra-scrotal testicle remains palpable and stable in size. Serum testosterone is unchanged from preoperative measurements. Robotic-assisted testicular autotransplantation is a feasible and efficacious management option for the solitary intra-abdominal testis.
