Low-dose interleukin-2 promotes immune regulation in face transplantation: A pilot study.

Face transplantation is a life-changing procedure for patients with severe composite facial defects. However, it is hampered by high acute rejection rates due to the immunogenicity of skin allograft and toxicity linked to high doses of immunosuppression. To reduce immunosuppression-associated complications, we, for the first time in face transplant recipients, used low-dose interleukin 2 (IL-2) therapy to expand regulatory T cells (Tregs) in vivo and to enhance immune modulation, under close immunological monitoring of peripheral blood and skin allograft. Low-dose IL-2 achieved a sustained expansion (∼4-fold to 5-fold) of circulating Tregs and a reduction (∼3.5-fold) of B cells. Post-IL-2 Tregs exhibited greater suppressive function, characterized by higher expression of TIM-3 and LAG3co-inhibitory molecules. In the skin allograft, Tregs increased after low-dose IL-2 therapy. IL-2 induced a distinct molecular signature in the allograft with reduced cytotoxicity-associated genes (granzyme B and perforin). Two complications were observed during the trial: one rejection event and an episode of autoimmune hemolytic anemia. In summary, this initial experience demonstrated that low-dose IL-2 therapy was not only able to promote immune regulation in face transplant recipients but also highlighted challenges related to its narrow therapeutic window. More specific targeted Treg expansion strategies are needed to translate this approach to the clinic.

All hands on deck: Hand replantation versus transplantation.

OBJECTIVES: Our hands play a remarkable role in our activities of daily living and the make-up of our identities. In the United States, an estimated 41,000 individuals live with upper limb loss. Our expanding experience in limb transplantation-including operative techniques, rehabilitation, and expected outcomes-has often been based on our past experience with replantation. Here, we undertake a systematic review of replantation with transplantation in an attempt to better understand the determinants of outcome for each and to provide a summary of the data to this point. METHODS: Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, we conducted PubMed searches from 1964 to 2013 for articles in English. In total, 53 primary and secondary source articles were found to involve surgical repair (either replantation or transplantation) for complete amputations at the wrist and forearm levels. All were read and analyzed. RESULTS: Hand replantations and transplantations were compared with respect to pre-operative considerations, surgical techniques, post-operative considerations and outcomes, including motor, sensation, cosmesis, patient satisfaction/quality of life, adverse events/side effects, financial costs, and overall function. While comparison of data is limited by heterogeneity, these data support our belief that good outcomes depend on patient expectations and commitment. CONCLUSION: When possible, hand replantation remains the primary option after acute amputation. However, when replantation fails or is not possible, hand transplantation appears to provide at least equal outcomes. Patient commitment, realistic expectations, and physician competence must coincide to achieve the best possible outcomes for both hand replantation and transplantation.

Software-based video analysis of functional outcomes of face transplantation.

INTRODUCTION: Assessment of outcomes after face transplantation (FT) is necessary to provide sound evidence on the benefits of this life-giving surgery. Current methods for outcomes assessment, however, are imprecise or prone to subjectivity. Software-based video analysis may allow fast, objective and retrospective assessment of restoration of facial movements and functions after FT. PATIENTS AND METHODS: We recorded videos of 7 subjects before as well as every 3-6 months after facial transplantation. Patients performed the same sequence of facial movements in every video: smile, open mouth, purse lips, wrinkle nose, frown, close eyes, and lift eyebrows. The videos were retrospectively analyzed using EMOTIENT software, which is capable of automatic tracking and detailed measurements of facial movements and expressions. These measurements were subsequently compared to the same patient at different time points, as well as to the normal population. RESULTS: Open mouth, wrinkle nose and smile functions significantly improved in all patients when compared to pre-transplant functions; this improvement was significant at 3, 6, and 12 months after transplant, respectively. Lip purse, eye closure and frown functions improved by 6, 9, and 18 months after transplantation, respectively; however, improvement in these particular functions was not significantly with respect to pre-transplant. Face transplantation did not improve any of the patients' ability to lift their eyebrows. Most remarkably, mouth opening and smiling functions both reached values comparable to the normal population at 3 and 12 months after transplantation, respectively. CONCLUSION: Software-based video analysis provides a valuable assessment tool capable of objective, precise and reproducible analysis of facial movements and functions after FT.

Reduced Hypoxia-Related Genes in Porcine Limbs in Ex Vivo Hypothermic Perfusion Versus Cold Storage.

BACKGROUND: Ischemia-reperfusion injury remains the major limiting factor for limb replantation and transplantation. Static cold storage (SCS) on ice currently represents the standard mode of preservation but is limited to 6 h of duration. Ex vivo machine perfusion has evolved as a potential alternative to safely extend the duration of ex vivo preservation by providing continuous supply of oxygen and nutrients. This study aims to evaluate underlying molecular mechanisms of both preservation modalities. METHODS: We assessed molecular changes in amputated porcine forelimbs stored on ice at 4°C for 2 h (n = 2) and limbs perfused with Perfadex solution at 10°C for 2 h (n = 3) or 12 h (n = 3) before replantation. Muscle biopsies were examined for histological changes and gene expression levels using H&E staining and a hypoxia-related PCR gene array, respectively. RESULTS: Histology revealed only minor differences between the ice (SCS) and perfusion groups after 2 h of preservation, with decreased muscle fiber disruption in the perfusion groups compared with the ice (SCS) group. Perfused limbs demonstrated downregulation of genes coding for glycolytic pathways and glucose transporters after 2 h and 12 h when compared with SCS after 2 h. Similarly, genes that induce angiogenesis and those that are activated on DNA damage were downregulated in both perfusion groups as compared with SCS. CONCLUSIONS: Perfusion of porcine limbs resulted in less activation of hypoxia-related gene families when compared with SCS. This may indicate a state more closely resembling physiological conditions during perfusion and potentially limiting ischemic injury. Our study confirms ex vivo perfusion for up to 12 h as a viable alternative for preservation of vascularized composite tissues.

Kidney Dysfunction After Vascularized Composite Allotransplantation.

BACKGROUND: Kidney dysfunction is a major complication after nonrenal solid organ transplants. Transplantation of vascularized composite allografts (VCA) has yielded successful midterm outcomes despite high rates of acute rejection and greater requirements of immunosuppression. Whether this translates in higher risks of kidney complications is unknown. METHODS: Ninety-nine recipients of facial or extremity transplants from the Brigham and Women's Hospital (BWH) and the International Registry on Hand and Composite Tissue Transplantation (IR) were reviewed. We assessed immunosuppression, markers of renal function over time, as well as pretransplant and posttransplant renal risk factors. RESULTS: Data were obtained from 10 patients from BWH (age at transplant, 42.5 ± 13.8 years) and 89 patients (37.8 ± 11.5 years) from IR. A significant rise in creatinine levels (BWH, P = 0.0195; IR, P < 0.0001) and drop in estimated glomerular filtration rate (GFR) within the first year posttransplant was observed. The BWH and IR patients lost a mean of 22 mL/min GFR and 60 mL/min estimated GFR in the first year, respectively. This decrease occurred mostly in the first 6 months posttransplant (BWH). Pretransplant creatinine levels were not restored in either cohort. A mixed linear model identified multiple variables correlating with renal dysfunction, particularly tacrolimus trough levels. CONCLUSIONS: Kidney dysfunction represents a major complication posttransplantation in VCA recipients early on. Strategies to mitigate this complication, such as reducing calcineurin inhibitor trough levels or using alternative immunosuppressive agents, may improve long-term patient outcomes. Standardizing laboratory and data collection of kidney parameters and risk factors in VCA patients will be critical for better understanding of this complication.

Living Donation of Vascularized Composite Allografts.

Living donation has become a medically and ethically accepted practice in solid organ transplantation. Published proceedings from the international kidney transplant community and from the Ethics Committee of The Transplantation Society articulated the general principles and specific recommendations for living donation, which remain the backbone of Centers for Medicare and Medicaid Services and Organ Procurement and Transplantation Network requirements and policies. Meanwhile, there have been major advancements in another revolutionary field of transplant medicine: vascularized composite allotransplantation. Recent interventions have demonstrated potential for superior functional and aesthetic outcomes in a single operation when compared to staged conventional reconstructions. In view of these successes, the indications for vascularized composite allotransplantation are expected to broaden to include less extensive types of transplants, which would introduce the possibility of using living vascularized composite allotransplantation donors. In this article, the authors discuss the feasibility and ethics associated with living donation of vascularized composite allografts. The authors explore the current guidelines and policies set by the Organ Procurement and Transplantation Network regarding living organ donation. In addition, the authors provide several clinical scenarios in which living donation of vascularized composite allotransplantation could be used to augment the reconstructive ladder currently used by reconstructive surgeons to guide their reconstructive strategies.

Quality of Life and Psychosocial Functioning 2 Years Following Facial Transplantation.

BACKGROUND: Face transplantation is a novel option for patients with severe facial disfigurement. Quality of life (QoL) outcomes of face transplantation remain poorly understood. OBJECTIVES: We sought to evaluate psychosocial functioning among 6 patients undergoing facial transplantation. METHODS: We prospectively assessed depressive symptoms, health status, mental and physical QoL, and self-esteem at 3-month intervals for 2 years. Social desirability was assessed pretransplant. RESULTS: On average, before transplantation, patients generally reported minimal to subthreshold depressive symptoms, normal to high health status, normal mental-health QoL, slightly below normal physical-health QoL, and normal to high self-esteem. Most endorsed high social desirability. As patients recovered from surgery, hospitalization, and immunosuppression induction, physical-health QoL generally deteriorated 3 months posttransplantation. Posttransplant trajectories show that perceived health state improved; health status and mental and physical health-related QoL slightly improved; self-esteem remained stable and high; and overall depressive symptoms remained stable but 3 patients experienced a depressive episode. CONCLUSIONS: Pretransplant ceiling effects may render improvements difficult to quantify. Future research should use mixed methods including population-specific measures with demonstrated sensitivity to change.

Face transplantation-current status and future developments.

More than thirty-five facial allograft transplantations (FAT) have been reported worldwide since the pioneering case performed in France in the year 2005. FAT has received tremendous interest by the medical field and the general public while gaining strong support from multiple disciplines as a solution for reconstructing complex facial defects not amenable/responsive to conventional methods. FAT has expanded the frontiers of reconstructive microsurgery, immunology and transplantation, and established its place in the cross section of multiple disciplines. The procedure introduces complex scientific, ethical, and societal issues. Patients and physicians are called to deal with a variety of-sometimes everlasting-challenges, such as immunosuppression management and psychosocial hurdles. This review reflects on the surgical and scientific advancements in FAT and milestones reached in the last 12 years. It aims to encourage active discussion regarding the current practices and techniques used in FAT and suggest future directions that may allow transitioning into the next phase of FAT, which we describe as safe, reliable, and accessible standard operation for selected patients.

Trismus in Face Transplantation Following Ballistic Trauma.

BACKGROUND: Trismus can be a challenging consequence of ballistic trauma to the face, and has rarely been described in the setting of face transplantation. Almost half of all current face transplant recipients in the world received transplantation to restore form and function after a ballistic injury. Here we report our experience and challenges with long standing trismus after face transplantation. METHODS: We reviewed the medical records of our face transplant recipients whose indication was ballistic injury. We focused our review on trismus and assessed the pre-, peri- and postoperative planning, surgery and functional outcomes. RESULTS: Two patients received partial face transplantation, including the midface for ballistic trauma. Both patients suffered from impaired mouth opening, speech intelligibility, and oral competence. Severe scarring of the temporomandibular joint (TMJ) required intraoperative release in both patients, and additional total condylectomy on the left side 6 months posttransplant for 1 patient. Posttransplant, both patients achieved an improvement in mouth opening; however, there was persistent trismus. One year after transplantation, range of motion of the jaw had improved for both patients. Independent oral food intake was possible 1 year after surgery, although spillage of liquids and mixed consistency solids persisted. Speech intelligibility testing showed impairments in the immediate postoperative period, with improvement to over 85% for both patients at 1 year posttransplant. CONCLUSIONS: Ballistic trauma to the face and subsequent reconstructive measures can cause significant scarring and covert injuries to structures such as the TMJ, resulting in long standing trismus. Meticulous individual planning prior to interventions such as face transplantation must take these into account. We encourage intraoperative evaluation of these structures as well as peri- and postoperative treatment when necessary. Due to the nature of the primary injury, functional outcomes after face transplantation in these patients may differ substantially from those of other indications.

Longitudinal immunological characterization of the first presensitized recipient of a face transplant.

Rejection affects greater than 80% of face transplants, yet no diagnostic criteria for antibody-mediated rejection (AMR) following face transplantation have been established. Given that different treatment strategies are required to address AMR and T cell-mediated rejection (TCMR), there is a critical need to delineate the features that can differentiate these two alloimmune responses. Here, we report the longitudinal immunological examination of what we believe to be the first and only highly sensitized recipient of a crossmatch-positive face transplant up to 4 years following transplantation. We conducted gene expression profiling on allograft biopsies collected during suspected AMR and TCMR episodes as well as during 5 nonrejection time points. Our data suggest that there are distinctive molecular features in AMR, characterized by overexpression of endothelial-associated genes, including ICAM1, VCAM1, and SELE. Although our findings are limited to a single patient, these findings highlight the potential importance of developing and implementing molecular markers to differentiate AMR from TCMR to guide clinical management. Furthermore, our case illustrates that molecular assessment of allograft biopsies offers the potential for new insights into the mechanisms underlying rejection. Finally, our medium-term outcomes demonstrate that face transplantation in a highly sensitized patient with a positive preoperative crossmatch is feasible and manageable.

The Effects of Lip-Closure Exercise on Lip Strength and Function Following Full Facial Transplantation: A Case Report.

PURPOSE: Facial transplantation is a relatively new option for individuals with severe facial disfigurements. Clinical case studies on existing patients indicate many instances of persistent facial motor impairment for facial expression, speech, and swallowing. These preliminary findings motivate additional research on the impact of lip-strengthening exercises following facial transplantation. METHOD: In this study, we assessed the efficacy of an 8-week, biofeedback-driven, lip closure-strengthening exercise program in a single patient 1-year status post-full facial transplantation. Exercise was at 60% of peak strength. Outcome measures included instrumental measures of lip strength and mobility, clinical measures of speech, and patient-reported outcomes in feeding and facial expression. RESULTS: Results revealed improvements in labial strength, speed of lip movement, and range of motion during speech. A 3-point improvement in sentence speech intelligibility was also observed following strength-training exercise. The patient reported improvements in her ability to drink from a straw and communicate via facial expression. CONCLUSION: These preliminary findings motivate additional research on the efficacy of lip-strengthening exercises following facial transplantation.

Experience With Patient Referrals for Upper Extremity Transplantation at a U.S. Academic Medical Center.

PURPOSE: To date, there have been over 100 upper extremity transplantations (UET) performed worldwide. However, little data are available regarding institutional screening practices or description of the population of patients that seek transplantation as a treatment modality for their upper extremity disabilities. We performed a review of our institutional experience in an attempt to better understand our referral patterns and identify factors that may be associated with successful screening. METHODS: Contact demographic data, injury characteristics, and mode of referral were retrospectively reviewed from 2010 through 2015. Differences in demographic data, injury-related characteristics, and clinical trial outcomes were assessed with the Chi-square test or Fisher exact test. RESULTS: There were a total of 89 UET contacts. The average age was 35.2 years, with most contacts being white (n = 24). The majority were male (n = 66; 75.0%) and the most common indication for referral was trauma (n = 43; 55.8%). Of the 89 contacts, 20 (22.5%) were physician referrals and 69 (77.5%) were self-referrals. Physician referrals led to the most screened and accepted contacts, whereas self-referrals more often led to immediate exclusion. CONCLUSIONS: This study gives an overview of the demographic composition of our UET contacts, with a specific emphasis on mode of referral. We have identified that physician referrals have led to more screened and accepted patients versus self-referred individuals. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic, Level IV.

First Lower Two-Thirds Osteomyocutaneous Facial Allograft Perfused by a Unilateral Facial Artery: Outcomes and Vascularization at 1 Year after Transplantation.

BACKGROUND: Facial allotransplantation provides a unique opportunity to restore facial form and function in severely disfigured patients. Using a single unilateral facial artery for vascularization can significantly reduce surgical duration and thus facilitate the practice of face transplantation. METHODS: A 33-year-old man with a history of high-energy ballistic trauma received a facial allograft comprising the lower two-thirds of the face, including maxilla and mandible. Vascular anastomoses involved one unilateral facial artery and two veins. Vascularization patterns, airway volume, and facial functions were assessed before and 1 year after transplantation. In addition, immunosuppressive therapy and rejection episodes were recorded. RESULTS: One year after transplantation, the facial allograft is well perfused and gradually improving in function. Unilateral facial artery anastomosis remains patent and collateralization with the contralateral side is taking place through collaterals of the submental arteries. Bony perfusion of the maxilla and mandible is provided periosteally. Bilateral venous outflow is evident. Airway volume is significantly increased compared with before transplantation, and gastrostomy and tracheostomy tubes have been securely removed. The recipient has gained the abilities to smell, speak, feel, and grimace 1 year after transplantation. Steroids were successfully weaned after 9 months, leaving the patient on dual immunosuppressive therapy with tacrolimus and mycophenolate mofetil. Two rejection episodes occurred, of which one was treated by steroid pulse and the other by adjusting the maintenance therapy. CONCLUSIONS: In this patient, a facial allograft comprising the lower two-thirds of the face including the maxilla and mandible is sufficiently perfused by one unilateral facial artery. Bilateral venous outflow, however, seems to be necessary. Facial allotransplantation can significantly and securely improve facial form and function. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, V.

Acellular Hypothermic Extracorporeal Perfusion Extends Allowable Ischemia Time in a Porcine Whole Limb Replantation Model.

BACKGROUND: One of the major challenges in traumatic amputation is the need to keep ischemia time brief (4 to 6 hours) to avoid ischemic damage and enable successful replantation. The current inability to meet this challenge often leads to traumatic limb loss, which has a considerable detrimental impact on the quality of life of patients. METHODS: The authors' team built a portable extracorporeal membrane oxygenator device for the perfusion of amputated extremities with oxygenated acellular solution under controlled parameters. The authors amputated forelimbs of Yorkshire pigs, perfused them ex vivo with acellular Perfadex solution for 12 hours at 10°C in their device, and subsequently replanted them into the host animal. The authors used limbs stored on ice slurry for 4 hours before replantation as their control group. RESULTS: Clinical observation and histopathologic evaluation both demonstrated that there was less morbidity and less tissue damage to the cells during preservation and after replantation in the perfusion group compared with the standard of care. Significant differences in blood markers of muscle damage and tissue cytokine levels underscored these findings. CONCLUSIONS: The authors demonstrated the feasibility and superiority of ex vivo hypothermic oxygenated machine perfusion for preservation of amputated limbs over conventional static cold storage and herewith a substantial extension of the allowable ischemia time for replantation after traumatic amputation. This approach could also be applied to the field of transplantation, expanding the potential pool of viable donor vascularized composite allografts.

Tissue conservation for transplantation.

Pathophysiological changes that occur during ischemia and subsequent reperfusion cause damage to tissues procured for transplantation and also affect long-term allograft function and survival. The proper preservation of organs before transplantation is a must to limit these injuries as much as possible. For decades, static cold storage has been the gold standard for organ preservation, with mechanical perfusion developing as a promising alternative only recently. The current literature points to the need of developing dedicated preservation protocols for every organ, which in combination with other interventions such as ischemic preconditioning and therapeutic additives offer the possibility of improving organ preservation and extending it to multiple times its current duration. This review strives to present an overview of the current body of knowledge with regard to the preservation of organs and tissues destined for transplantation.

Long-Term Effects of the Collagenase of the Bacterium Clostridium histolyticum for the Treatment of Capsular Fibrosis After Silicone Implants.

BACKGROUND: Capsular contracture remains the most frequent long-term complication after augmentation mammoplasty with silicone implants. Thereby, the main part of the fibrotic capsule is collagen. The collagenase of the bacterium Clostridium histolyticum is approved for the treatment of fibrotic diseases and has been demonstrated to be effective for capsular fibrosis treatment in the short term. However, long-term effectiveness is currently unknown but mandatory for clinical utilization. MATERIALS AND METHODS: Forty-eight rats received miniature silicone implants and an injection with either collagenase (treatment group) or plain solvent solution (control group) 120 days post insertion. Ten and 60 days after the injections, the rats underwent 7-Tesla magnetic resonance imaging (MRI) and high-resolution ultrasound (HR-US). Capsule tissue was harvested, and capsule thickness and collagen density were evaluated through histology. Furthermore, the expression levels of inflammatory (CD68, IL4, IL10, IL12, IL13), pro-, and anti-fibrotic (TGFb1, TGFb3, Smad3, Col1-4) genes were analyzed using qRT-PCR. RESULTS: On days 10 and 60 after injection of collagenase, histology showed that capsule thickness was significantly reduced in the treatment group when compared with the control (p < 0.05). Thickness measurements were verified by MRI and HR-US analysis. Skin perforation occurred in two cases after collagenase injection. The initial up-regulation of pro-fibrotic and inflammatory genes 10 days after collagenase injection did not persist in the long term. Contrarily, on day 60, a slight trend towards lower expression levels with a significant down-regulation of TGFb3 was detected in the treatment group. CONCLUSION: The collagenase of the bacterium C. histolyticum effectively degrades capsular fibrosis around silicone implants with stable outcomes throughout 60 days post injection. Skin perforation and adequate and uniform drug distribution within the implant pocket are issues that need to be addressed. Further studies are warranted to clarify whether collagenase injections have the potential to become a viable treatment option for capsular contracture.

Quality of Life after Face Transplantation: Outcomes, Assessment Tools, and Future Directions.

BACKGROUND: Face transplantation has emerged as a clinical reality for the restoration of complex facial defects. Critical to the advancement of the burgeoning field of reconstructive transplantation is the quality of the methods used to measure and report the impact of face transplantation on quality of life. METHODS: A systematic search using PubMed and EMBASE was conducted for all studies matching the a priori inclusion criteria from 2005 through 2015. Bibliographies of included studies were also reviewed. Two authors (M.A.A and H.K) independently performed screening of titles. RESULTS: The authors identified 17 articles reporting on quality-of-life outcomes among 14 face transplant recipients. Combinations of objective and subjective measures were used to assess quality of life. Instruments used to assess quality of life after face transplantation included over 25 different instruments. Four centers, comprising eight patients, have reported using prospective, systematic data with validated instruments. Overall, there is reported improvement in quality of life after face transplantation. Heterogeneity and a paucity of data between articles preclude a quantitative analysis. CONCLUSIONS: Anecdotal and subjective reports of improvements in quality of life after face transplantation constitute the majority of reported outcomes in the English peer-reviewed literature. Improved efforts in methods and standardization of collection and reporting of quality-of-life data after face transplantation are needed to better appreciate the impact of face transplantation on quality of life and justify lifelong immunosuppression and its attendant risks and morbidity.

Outcomes of Solid Organ Transplants After Simultaneous Solid Organ and Vascularized Composite Allograft Procurements: A Nationwide Analysis.

BACKGROUND: Current knowledge of the impact of facial vascularized composite allograft (VCA) procurement on the transplantation outcomes of the concomitantly recovered solid organs is limited to isolated case reports and short-term results. Here we report on a nationwide analysis of facial allograft donor surgery experience and long-term outcomes of the concomitantly recovered solid organs and their recipients. METHODS: There were 10 facial VCA procurements in organ donors between December 2008 and October 2014. We identified the population of subjects who received solid organs from these 10 donors using the Scientific Registry of Transplant Recipients. We retrospectively reviewed operative characteristics, intraoperative parameters, and postoperative outcomes. RESULTS: Six of 10 donor surgeries were performed at outside institutions, all on brain-dead donors. Mean operative duration for facial VCA recovery was 6.9 hours (range, 4-13.25 hours). A total of 36 solid organs were recovered and transplanted into 35 recipients. Survival rates for kidney and liver recipients were 100% and 90% at a median follow-up of 33 and 27.5 months, respectively (range, 6-72 months). Graft survival rates for kidneys and livers were 15 of 16 (94%) and 9 of 10 (90%), respectively. Recipient and graft survival rates for hearts and lungs were 75% (n = 4) and 100% (n = 3) at mean follow-up time of 14.75 and 16 months, respectively. A liver recipient died at 22 months from unknown causes and a heart recipient died of leukemia at 10 months. CONCLUSIONS: Facial VCA procurement does not appear to adversely affect the outcomes of transplant recipients of concomitantly recovered solid organ allografts.

The role of face transplantation in the self-inflicted gunshot wound.

BACKGROUND: Facial self-inflicted gunshot wounds (SIGSWs) cause a devastating midfacial defect and pose a challenging problem to the reconstructive surgeon. Face transplantation (FT) has the potential for near-normal restoration in otherwise non-reconstructible defects. Two out of 7 FT recipients at Brigham and Women's Hospital (BWH) sustained SIGSWs. In this study, we illustrate the role of FT in the management of SIGSWs through an aesthetic, functional, and psychosocial examination of outcomes. METHODS: We performed a retrospective analysis of individuals with SIGSWs who were screened at BWH between 2008 and 2015. We then collected data of the injuries, modes of conventional reconstruction (CR), and deficits. For the FT recipients, we critically reviewed the psychosocial screening process and post-transplantation aesthetic, functional, and psychosocial outcomes. RESULTS: A total of six individuals post-SIGSWs were screened for FT. All of them had undergone CR, with five receiving loco-regional flaps and free tissue transfers, and one undergoing serial debridement and primary soft-tissue repair. Following CR, all suffered from residual functional and aesthetic deficits. Two underwent partial FT and one is currently undergoing FT screening. We describe the pre-transplant psychosocial screening process and the aesthetic, functional, and psychosocial outcomes of the SIGSW FT recipients. CONCLUSIONS: We examined the facial SIGSW injury, outcomes of CR, and the mechanism of FT to offer a potential solution to the shortcomings of CR. More importantly, we highlight the critical nature of the psychosocial component of the multidisciplinary evaluation given the history of mental illness and suicidal behavior in this subset of patients.
