RESUMO

Face transplantation is a viable reconstructive approach for severe craniofacial defects. Despite the evolution witnessed in the field, ethical aspects, clinical and psychosocial implications, public perception, and economic sustainability remain the subject of debate and unanswered questions. Furthermore, poor data reporting and sharing, the absence of standardized metrics for outcome evaluation, and the lack of consensus definitions of success and failure have hampered the development of a "transplantation culture" on a global scale. We completed a 2-round online modified Delphi process with 35 international face transplant stakeholders, including surgeons, clinicians, psychologists, psychiatrists, ethicists, policymakers, and researchers, with a representation of 10 of the 19 face transplant teams that had already performed the procedure and 73% of face transplants. Themes addressed included patient assessment and selection, indications, social support networks, clinical framework, surgical considerations, data on patient progress and outcomes, definitions of success and failure, public image and perception, and financial sustainability. The presented recommendations are the product of a shared commitment of face transplant teams to foster the development of face transplantation and are aimed at providing a gold standard of practice and policy.

RESUMO

BACKGROUND: Deep inferior epigastric perforator (DIEP) flaps are commonly used for autologous breast reconstruction, but reported rates of venous thromboembolism (VTE) are up to 6.8%. This study aimed to determine the incidence of VTE based on preoperative Caprini score following DIEP breast reconstruction. METHODS: This retrospective study included patients who underwent DIEP flaps for breast reconstruction between January 1, 2016 and December 31, 2020 at a tertiary-level, academic institution. Demographics, operative characteristics, and VTE events were recorded. Receiver operating characteristic analysis was performed to determine the area under the curve (AUC) of the Caprini score for VTE. Univariate and multivariate analyses assessed risk factors associated with VTE. RESULTS: This study included 524 patients (mean age 51.2 ± 9.6 years). There were 123 (23.5%) patients with the Caprini score of 0 to 4, 366 (69.8%) with scores 5 to 6, 27 (5.2%) with scores 7 to 8, and 8 (1.5%) patients with scores >8. Postoperative VTE occurred in 11 (2.1%) patients, at a median time of 9 days (range 1-30) after surgery. VTE incidence by the Caprini score was 1.9% for scores 3 to 4, 0.8% for scores 5 to 6, 3.3% for scores 7 to 8, and 13% for scores >8. The Caprini score achieved an AUC of 0.70. A Caprini score >8 was significantly predictive of VTE on multivariable analysis relative to scores 5 to 6 (odds ratio = 43.41, 95% confidence interval = 7.46-252.76, p < 0.001). CONCLUSION: In patients undergoing DIEP breast reconstruction, VTE incidence was highest (13%) in Caprini scores greater than eight despite chemoprophylaxis. Future studies are needed to assess the role of extended chemoprophylaxis in patients with high Caprini scores.

RESUMO

BACKGROUND: The field of face transplantation continues to evolve, with more complex defects being addressed, and, at the same time, increased outcome expectations. Given our unique long-term experience in this field, we consented one of the youngest patients to undergo a full-face transplant. METHODS: An 18-year-old woman presented with complete destruction of her central face and craniofacial structures. She had coexisting major injuries, including pituitary gland, visual axis, and motor control. After extensive rehabilitation and reconstruction techniques, the patient underwent face transplant on May 4, 2017, at the age of 21 years. RESULTS: The total operative time for the recipient was 26 hours. There were no major perioperative complications. Since transplant, the patient has undergone 3 revision surgeries. She is near completely independent from a daily life activity standpoint. She has had 1 episode of rejection above grade II that was successfully treated with a short-term increased in immunosuppression. CONCLUSIONS: Contrary to data in solid organ transplantation where youth is associated with increased risk of rejection, our current algorithm in immunosuppression, combined with this patient's compliance, has led to only 1 rejection episode beyond grade II. This successful transplant can serve as a model for future vascularized composite transplants in younger populations.

RESUMO

BACKGROUND: Neurotization during the breast reconstruction process can improve patient quality-of-life and satisfaction with reconstructive outcomes. One concern with neurotization is increased total operative time due to the need for additional dissection and nerve coaptation. The purpose of this study was to compare total operative time between neurotized and non-neurotized abdominal-based, free flap breast reconstruction. METHODS: A retrospective review was conducted of consecutive patients who underwent unilateral, abdominal-based, free flap breast reconstruction between 2016 and 2018 at a single tertiary care center. Data were collected on patient demographics, surgical techniques, and length of surgery. Data analysis was performed using chi-square test, independent t-test, and multivariate linear regression analysis. A p-value ≤0.05 was considered statistically significant. RESULTS: Seventy-three patients were included in this study. Twenty-three patients (31.50%) underwent flap neurotization (N group) and 50 (68.49%) underwent standard breast reconstruction without neurotization (NO group). The groups were similar in age, BMI, smoking status, and ASA class. No difference was found between the two groups in timing of reconstruction (p = 0.388). Average operative times were 467.73 ± 145.52 minutes and 455.28 ± 111.19 minutes for the N and NO groups, respectively, with no significant difference between the two groups (two-tailed p-value = 0.72). CONCLUSION: Seamless integration of neurotization in abdominal-based, free flap breast reconstruction is possible without significant prolongation of total operative time.

RESUMO

BACKGROUND: Dynamic and functional abdominal wall reconstruction (FAWR) remains a complex challenge. The ideal flap should have a minimal donor-site morbidity and cover a large surface area with motor and sensory capabilities. The goal was to investigate the feasibility of using a free chimeric flap with anterolateral thigh (ALT) and rectus femoris (RF) components pedicled only on the motor nerve branch. METHODS: Ten fresh cadavers were dissected with a designed chimeric thigh flap including ALT and RF flaps. Anterolateral thigh was designed and raised with the lateral femoral cutaneous nerve integrated, and the descending branch of the lateral circumflex femoral artery was preserved. Rectus femoris was elevated and the common pedicle was dissected up to the femoral origin. Accompanying motor nerve branches were carefully dissected to their femoral origin. RESULTS: Twenty RF flaps were dissected and 9 were harvested as a true chimeric flap with ALT. The mean number of neurovascular bundles associated with RF flap was 2.11 ± 0.47, and the mean primary motor nerve average length was 9.40 ± 2.42 cm. The common vascular bundle in all 9 chimeric flaps was ligated, and the flap was rotated toward the abdomen pedicled only by primary motor nerve of the RF muscle. Nerve length was adequate for reach up to xiphoid area in all 20 flaps. CONCLUSIONS: This study demonstrates the feasibility of the chimeric ALT/RF muscle free flap pedicled only by the motor nerve branch, with adequate flap rotation. Even with the limitations in a live patient, this flap would be an excellent option for FAWR in the right patient.

RESUMO

ABSTRACT: Breast augmentation is among the most commonly performed cosmetic procedures in the United States. As these patients age or develop comorbidities, surgeons across many other disciplines will inevitably encounter these patients in their own practices. Consequently, surgeons must be aware of the potential interactions between breast implants and devices commonly used in their fields. This case, the second of its kind encountered by our own department, describes a woman who suffered one such interaction: migration and coiling of a ventriculoperitoneal shunt around her breast implant. A systematic review was conducted to characterize breast-related ventriculoperitoneal shunt complications reported in the literature and generate an algorithm for management of the most commonly reported scenarios. Recognition of potential complications will aid surgeons in appropriate operative planning and prevention of these adverse events.

RESUMO

BACKGROUND: Deep inferior epigastric perforator (DIEP) flaps are the standard for autologous breast reconstruction. This study investigated risk factors for DIEP complications in a large, contemporary cohort to optimize surgical evaluation and planning. METHODS: This retrospective study included patients who underwent DIEP breast reconstruction between 2016 and 2020 at an academic institution. Demographics, treatment, and outcomes were evaluated in univariable and multivariable regression models for postoperative complications. RESULTS: In total, 802 DIEP flaps were performed in 524 patients (mean age, 51.2 ± 9.6 years; mean body mass index, 29.3 ± 4.5). Most patients (87%) had breast cancer; 15% were BRCA -positive. There were 282 (53%) delayed and 242 (46%) immediate reconstructions and 278 (53%) bilateral and 246 (47%) unilateral reconstructions. Overall complications occurred in 81 patients (15.5%), including venous congestion (3.4%), breast hematoma (3.6%), infection (3.6%), partial flap loss (3.2%), total flap loss (2.3%), and arterial thrombosis (1.3%). Longer operative time was significantly associated with bilateral immediate reconstructions and higher body mass index. Prolonged operative time (OR, 1.16; P = 0.001) and immediate reconstruction (OR, 1.92; P = 0.013) were significant predictors of overall complications. Partial flap loss was associated with bilateral immediate reconstructions, higher body mass index, current smoking status, and longer operative time. CONCLUSIONS: Prolonged operative time is a significant risk factor for overall complications and partial flap loss in DIEP breast reconstruction. For each additional hour of surgical time, the risk of developing overall complications increases by 16%. These findings suggest that reducing operative time through co-surgeon approaches, consistency in surgical teams, and counseling patients with more risk factors toward delayed reconstructions may mitigate complications. CLINICAL QUESTION/LEVEL OF EVIDENCE: Risk, III.

RESUMO

BACKGROUND: Most of the literature surrounding face transplantation focuses on technique, immunology, and psychology. Dental and skeletal outcomes remain persistently underreported. This study critically examined the worldwide face transplant experience to evaluate such outcomes. METHODS: A systematic review of all composite allografts containing midface and/or mandible was performed. Dental and skeletal complications were recorded. Formal imaging and photographs available in the literature were analyzed using skeletal measurements, soft-tissue cephalometrics, and the Angle classification. Outcomes of our face transplant patients, including condylar assessment and airway volume measurements, is also presented. RESULTS: Twenty-five patients received allografts containing midface (n = 7) or mandible (n = 2), whereas 16 contained a double-jaw. All midface-only transplants developed skeletal deformity; 57 percent developed a palatal fistula. Both partial and full arch transplantation patients developed skeletal deformity. Among double-jaw transplants, 69 percent developed palatal fistula or floor-of-mouth dehiscence, 66 percent developed malocclusion, 50 percent developed trismus, and 31 percent required corrective orthognathic surgery. In 40 percent of patients, malocclusion recurred after corrective orthognathic surgery. Forty percent of all patients developed dental cavities or periodontal disease. All of our patients received midface and/or mandible. One patient required corrective orthognathic surgery. Midfacial segments showed clockwise rotation. Airway volumes decreased over time. CONCLUSIONS: Skeletal and dental complications remain extremely common after facial allotransplantation involving either single- or double-jaw composites. Corrective orthognathic surgery and dental extraction is often necessitated. These data will aid face transplant teams during surgical planning and preoperative counseling. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, V.

RESUMO

A hands-on facial fracture simulation course can be an important adjunct teaching modality in resident education and training, enhancing both resident confidence and competence in treatment of facial fractures. In this study, 11 plastic surgery residents participated in a surgical wet laboratory and lecture focusing on operative management of facial fractures. Pre- and post-course questionnaires were administered as clinical knowledge assessments. Pre-course, 40% of participating residents reported feeling comfortable with facial fracture management (>5 of 10) and 50% of residents achieved competence on clinical assessment (scoring >50%). Following the simulation course, these same assessments were re-administered. Post-course, comfortability with fracture management increased to 100% among participating residents, and 90% of residents scored >50%, demonstrating improvement in clinical competency.

RESUMO

INTRODUCTION: Contralateral prophylactic mastectomy has the potential to decrease the occurrence of cancer and reduce psychological burden. However, it is known that complications after bilateral mastectomy are higher compared with unilateral mastectomy. Our goal was to evaluate outcomes of immediate breast reconstruction in patients undergoing bilateral mastectomy and to compare complication rates between therapeutic and prophylactic sides. PATIENTS AND METHODS: Electronic medical records of patients with unilateral breast cancer who underwent bilateral mastectomy and immediate reconstruction with expanders were reviewed. Postoperative complications were compared between therapeutic and prophylactic mastectomy sides. RESULTS: Sixty-two patients were analyzed. The overall complication rate after both stages was 23.9% on the therapeutic side and 16.5% on the prophylactic side. Infection was the most common complication on both sides. All infections on the prophylactic mastectomy side were successfully treated with intravenous (IV) antibiotics (salvage rate of 100%), whereas 35.7% of infected tissue expander/implants on the therapeutic mastectomy side were explanted despite treatment. CONCLUSION: Careful counselling of patients undergoing elective contralateral prophylactic mastectomy is essential as complications can develop in either breast after reconstruction.
