RESUMO
Facial transplantations have become a clinical reality as the last reconstructive option in severely disfigured patients. To date, clinical outcomes remain unclear. The purpose of this paper was to analyse the outcomes in facial transplantation (FT) and determine the risks and benefits of FT based on short- and long-term outcomes. An electronic literature search was performed across PubMed, EMBASE and the Cochrane Central Register for Controlled Trials (CENTRAL) databases to capture all the relevant records relating to outcomes in FTs from 2005 to 2021. Articles for inclusion were decided upon pre-defined inclusion and exclusion criteria. A total of 48 FTs has been performed to date. A total of 90 studies met the eligibility criteria and were included in the outcome analysis. Studies were analysed based on each of the 48 cases and outcomes categorised into short-term (<36 months) and long-term (>36 months) outcomes. Primary outcomes included patient and graft survival and secondary outcomes included functional, surgical revision events, immunological, medical complications, aesthetics, psychosocial and quality of life. Mortality rate, infection and malignancy incidence remain high, and patients should be fully informed of the potential life-threatening complications. FTs improve outcomes such as quality of life and psychosocial recovery in the short- and long-term. Outcomes remain under-reported in peer-review journals.

Face transplant (FT) has emerged as a groundbreaking option for patients with severe facial deformities, resulting from congenital disorders, trauma, or tumor ablation. Although reconstructive surgery has made significant strides, the challenges of restoring both form and function remain, particularly in centrally located defects. This review explored the long-term outcomes of FT, addressing its challenges and potential pitfalls. A systematic review following the PRISMA guidelines was conducted, encompassing articles published in English from November 2005 to January 2023, which were searched across PubMed, MEDLINE, and EMBASE databases. Keywords included "face transplant," "face transplant outcomes," and "face transplant long-term." Data on surgical teams, patient demographics, transplant specifics, rejection episodes, additional surgeries, and patient-reported outcomes were extracted and analyzed. In total, 34 articles met the inclusion criteria. Over the 2 decades, 48 FT procedures were performed, with 23 patients followed for at least 3 years. Predominantly, patients were men (80%), averaging 31 years in age. Ballistic trauma (44.6%) and burns (25.5%) were common causes of injury. Chronic rejection emerged as a significant concern, leading to graft loss and necessitating retransplantation in 2 patients. Additional surgical procedures were often required. FT offers a remarkable solution for individuals with extensive facial disfigurement. Successful outcomes depend on factors, such as patient selection, multidisciplinary collaboration, psychiatric evaluation, and post-operative care. Nevertheless, challenges persist, including the need for lifelong immunosuppression and risk of chronic rejection. Although FT has transformed lives, continued success in this evolving field hinges on the ongoing research and vigilant patient management.

BACKGROUND: Since the first procedure performed in 2005, face transplantation has been debated as viable approach for the treatment of severe craniofacial defects. Despite the benefits provided, the experience in face allotransplantation has brought to light a significant risk of complications, including allograft removal or loss, and mortality. The present study is intended to provide an updated review on complications and major challenges witnessed over 18 years of experience in the field. METHODS: A systematic review of PubMed, MEDLINE, Cochrane, Google, and Google Scholar databases on face transplantation was conducted according to PRISMA guidelines up to April 2023. Articles providing details on cases of face allograft loss, removal, and patient death were included. Online articles and media reports were assessed to include information not disclosed in peer-reviewed literature. Face transplant centers were contacted to have updated follow-up information on single-face transplant cases. RESULTS: The search yielded 1006 reports, of which 28 were included. On a total of 48 procedures performed in 46 patients, adverse outcomes were gleaned in 14 cases (29%), including seven allograft losses (14.6%), and the death of ten patients (21.7%). Chronic rejection was the leading cause of allograft loss, with a median time from transplant to irreversible rejection of 90 months (IQR 88.5-102). The main causes of death were infectious complications, followed by malignancies, non-compliance to immunosuppression, and suicide. The median time to death was 48.5 months (IQR 19-122). CONCLUSIONS: To the best of our knowledge, this is the first study providing a comprehensive review of adverse outcomes in face transplantation. Considering the high rate of major complications, the heterogeneity of cases and single-center approaches, and the absence of published standards of care, the development of a consensus by face transplant teams holds the key to the field's advancement.

INTRODUCTION: There is a need to define what is success after face transplantation (FT). We have previously created a four-component criteria tool to define indications for FT. In this study, we used the same criteria to evaluate the overall outcome of our first two patients after FT. PATIENTS AND METHODS: Preoperative analysis of our two bimaxillary FT patients was compared to the results at four and six years post-transplantation. The facial deficiency impact was divided into four categories: (1) anatomical regions, (2) facial functions (mimic muscles, sensation, oral functions, speech, breathing, periorbital functions), (3) esthetics, and (4) impact on health-related quality of life (HRQoL). Immunological status and complications were also evaluated. RESULTS: For both patients, near-normal anatomical restoration of almost all the facial regions (except the periorbital and intraoral regions) was achieved. The majority of the facial function parameters improved in both patients (patient 2 to a near-normal level). The esthetic score improved from severely disfigured to impaired (patient 1) and to near to normal (patient 2). Quality of life was severely lowered prior to FT and improved after FT but was still affected. Neither patient has experienced acute rejection episodes during follow-up. CONCLUSIONS: We conclude that our patients have benefitted from FT, and we have succeeded. Time will reveal whether we have achieved long-term success.

BACKGROUND: Assessment of motor function restoration following face transplant (FT) is difficult, as standardized, bilateral tests are lacking. This study aims to bolster support for software-based analysis through international collaboration. METHODS: FaceReader (Noldus, Wageningen, The Netherlands), a facial expression analysis software, was used to analyze posttransplant videos of eight FT patients from Boston, Massachusetts (range, 1 to 9 years after transplant), two FT patients from Helsinki, Finland (range, 3 to 4 years after transplant), and three FT patients from Antalya, Turkey (range, 6.5 to 8.5 years after transplant). Age-matched healthy controls from respective countries had no history of prior facial procedures. Videos contained patients and controls performing facial expressions evaluated by software analysis using the Facial Action Coding System. Facial movements were assigned intensity score values between 0 (absent) and 1 (fully present). Maximum values were compared with respective healthy controls to calculate percentage restoration. RESULTS: Of 13 FT patients, eight patients were full FT, five patients were partial FT, and two patients were female patients. Compared with healthy controls, the median restoration of motor function was 36.9% (interquartile range, 28.8% to 52.9%) for all patients with FT ( P = 0.151). The median restoration of smile was 37.2% (interquartile range, 31.5% to 52.7%) for all patients with FT ( P = 0.065). When facial nerve coaptation was performed at the distal branch level, average motor function restoration was 42.7% ± 3.61% compared with 27.9% ± 6.71% at the proximal trunk coaptation level ( P = 0.032). Use of interpositional nerve grafts had no influence on motor outcomes. CONCLUSIONS: Software-based analysis is suitable to assess motor function after FT. International collaboration strengthens outcome data for FT. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

Facial allograft transplantation can be regarded as a particular and complex type of donation because of its perceptibility and the importance of the face as an identity characteristic. As research on this topic is currently lacking, the objective of this study is to explore the experiences of the family members of the donor in facial allograft donation. In-depth, semi-structured interviews were conducted separately with the donor's family members and analyzed using interpretative phenomenological analysis. Six themes were identified: (1) Contrasting facial donation to that of more commonly donated organs; (2) Consenting to facial donation; (3) Expectations towards the recipient of the facial graft; (4) Expectations and consequences of restoration of the donor's face; (5) Relationship with the medical team during the process; and (6) Media attention. The findings of our study help to better support donor families through the facial donation process and to improve facial transplantation procedures.

Cross-face nerve grafting (CFNG) allows for spontaneous, involuntary facial movement for patients with irreversible hemifacial paralysis. This technique uses an intact contralateral facial nucleus and nerve as an input and axon source, allowing donor neural input to be routed through a nerve graft across the face. The sural nerve is well equipped for use as a nerve graft due to its length and minimal donor site morbidity. Endoscopic nerve harvest techniques allow for efficient, minimally invasive dissection that improves the integrity of the harvested nerve.

Although there have been numerous scientific papers reporting on composite allotransplantation of the face, few have been about assessment and evolution of the functional benefit for patients in terms of soft tissue mobility, movement coordination, and face expressions, even fewer on the choice of the surgical procedures to restore motricity. On some videos and interviews, it is possible to analyze significative motricity. Of course that has been voluntary motricity, not emotional motricity. The data confirmed that the result on the complexity of the expression of the face is not great, providing opportunity to reflect on the question of nerve regeneration.

ABSTRACT: After the first face transplantation from woman to woman we performed in our clinic, it was aimed to eliminate the lack of knowledge about the subject in the literature by transferring our experiences and long-term results to the problems we had with the patient. A 20-year-old patient underwent partial osteomyocutaneous facial transplant (22nd facial transplant), which included 2 functional units of the face. The patient had no major problems in the early period and had a good aesthetic appearance. In the postoperative period, the patient ended her social isolation and adopted the transplanted face.In the late period, secondary surgical interventions, management of the problems caused by immunosuppression, and the patient's living in a remote location to our clinic were the difficulties encountered. Six revision surgeries were performed after the transplantation. Due to immunosuppression, opportunistic infections and metabolic problems required intermittent hospitalization. The patient died at the end of 56 months because of complications secondary to immunosuppression.A successful transplant involves the management of long-term problems rather than a successful tissue transfer in the early period. In today's conditions, long-term success can be achieved with a good patient compliance, as well as each team member should take an active role in the team at the transplantation centers. More case series are needed to adapt the standard treatment and follow-up protocols for solid organ transplantations for composite tissue allotransplantations. This will be possible by sharing the results and experiences transparently in the centers where face transplantation is performed worldwide.

INTRODUCTION: Facial transplantation has emerged as a viable option in treating devastating facial injuries.Despite the high healing rate of Le Fort III and bilateral sagittal split osteotomies (BSSO) in nontransplant patients, few studies have reported assessment of maxillary and mandibular healing in face transplant patients compared with nontransplant patients. The aim of this study was to examine differences in bone healing in our patients. PATIENTS AND METHODS: A retrospective chart review was conducted of facial allotransplantation patients at the Cleveland Clinic from December 2008 to inception. Demographics such as age, date of birth, and sex were recorded. Additional variables included procedures, revisions, reoperations, medications, and bone stability and healing. Computed tomography (CT) images assessed the alignment of skeletal components, bony union quality, and stability of fixation. RESULTS: Three patients were included: 2 had Le Fort III segment transplantation, and 1 had transplantation of both a Le Fort III segment and mandibular BSSO. The Le Fort III segment in all patients exhibited mobility and fibrous union at the Le Fort III osteotomy on CT. In contrast, the BSSO healed uneventfully after transplantation and revision surgery, with bony union confirmed by both CT and histology of the fixation area between the donor and recipient mandible bilaterally. No patients with midfacial fibrous union required revision of the nonunion as they were clinically asymptomatic. CONCLUSION: Le Fort osteotomy demonstrates inferior healing in facial transplantation compared with the nontransplant population. In contrast, the successful healing in the mandible is likely owing to the high density of rich cancellous bone.

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.

Although the ethical and technical feasibility of face transplant (FT) has been established, current literature lacks consensus on functional outcomes monitoring for recipients. This systematic review aims to appraise and summarize the current literature on tools used to assess motor functional outcomes in FT. This study complied with the guidelines outlined in the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA). On September 15, 2020, two reviewers conducted independent electronic searches using medical literature databases, without language or time frame limitations. Eligibility criteria included studies reporting on the evaluation of motor functional outcomes in face transplant recipients. Of 451 papers found in the literature, 12 fulfilled the study inclusion criteria. The reported tools included clinical scales/examinations, electromyography, optical movement tracking devices, muscle volumetric measurement using magnetic resonance imaging, and software-based video and photo analyses. The frequency of data collection varied from every three months to every year. Publications reporting on motor functional outcomes tracking tools vary broadly and demonstrate a lack of consensus. Although quantitative measurements are desirable, adapted clinical scales are still the current standard of care.

BACKGROUND: Recipient selection is an important determinant of surgical outcomes in facial transplantation (FT). Appropriately, each FT program develops their own guidelines for recipient selection criteria. Currently, there is no resource to simultaneously assess and identify similarities and differences between these guidelines. Such information could be useful in distinguishing areas of FT that are well understood from those that could benefit from further exploration. METHODS: We performed a systematic review of the scientific literature from inception to June 18, 2021, using Pubmed, Embase, Cochrane Library, and Scopus to identify articles pertaining to recipient selection criteria. Clinical trials were identified through the Clinicaltrials.gov registry. United States and international program websites were reviewed for patient-facing information. RESULTS: Our systematic review yielded 90 suitable articles, 8 clinical trials, and 7 program websites containing the recipient selection criteria of 24 different FT programs. The most reported on recipient criteria were age, positive human immunodeficiency viral status (HIV+), positive hepatitis C viral status, psychosocial stability, and medical compliance. Other criteria were rarely addressed, such as blindness and recipient immune status. CONCLUSIONS: Guidelines among different face transplant programs are changing over time. We found consensus on certain recipient selection criteria, but the majority remain program or surgeon dependent, emphasizing that FT is still an evolving procedure. Although most programs reported on their recipient selection criteria, the rationale was often missing. Further discussion about recipient selection criteria and the reasoning behind employing or changing them will help advance the field.

BACKGROUND: Facial fat grafts decrease in volume after transplantation. This observation is based on overall facial three-dimensional analyses, because there is sparse information on volume changes in well-defined aesthetic areas. The authors aimed to assess the overall and, more specifically, the local volumetric effects of facial fat grafting and relate these effects to patient satisfaction up to 1 year after treatment. METHODS: All consecutive adult female patients who were scheduled for facial fat grafting without additional surgical procedures were asked to participate. All patients underwent the same fat grafting method. An algorithm-based personalized aesthetic template was applied to define specific aesthetic areas on the preoperative three-dimensional image. Objective outcome parameters [i.e., three-dimensional volume differences, patient satisfaction (FACE-Q questionnaire)] were measured at baseline and at 6 weeks, 6 months, and 12 months after fat grafting. RESULTS: Of 33 female patients who underwent a facial fat graft procedure, 23 patients had complete three-dimensional data and were eligible for analysis. The highest volume gain was observed 6 weeks after grafting and was followed by a gradual loss thereafter. Overall and in the zygomatic area, a substantial gain in volume was still present 1 year after grafting, whereas this effect was lost in the lip area. FACE-Q scales Satisfaction with Facial Appearance Overall and Satisfaction with Cheeks improved too, whereas scores for Lines: Lips returned to baseline levels. The improvement in FACE-Q scales was in agreement with the objective change in volume. CONCLUSION: Gain in overall and local volumetric effects is accompanied by comparable changes in patient satisfaction. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

ABSTRACT: Vascularized composite allotransplantation of the face is an exceedingly complex procedure, requiring extensive planning and surgical precision in order to successfully manage patients with facial disfigurements. This review aims to present an overview of the salient anatomic considerations in facial transplantation, as well as give attention to unique patient populations and special considerations.A literature review was performed in search of articles pertaining to considerations in facial transplantation using the databases PubMed, Web of Science, and Cochrane. Articles selected for further review included full-text articles with an emphasis on specific anatomic defects and how they were addressed in the transplant process, as well as management of special patient populations undergoing facial transplantation. In total, 19 articles were deemed appropriate for inclusion.The use of computer-assisted technologies for the planning portion of the procedure, as well as intraoperative efficiency, has yielded favorable results and can be considered as part of the operative plan. The ultimate outcome is dependent upon the synchronization of subunits of the allograft and the desired functional outcomes, including osseous, ocular, oral, and otologic considerations. Management of specific pathology and subgroups of patients are critical aspects. Although pediatric face transplantation has not yet been performed, it is a likely a future step in the evolution of this procedure.When performing a face transplantation, many components must be considered pre-, intra-, and post-operatively. This systematic review presents specific anatomic considerations, as well as information about special patient populations within this crosssection of multidisciplinary microsurgery, psychiatry, and transplant immunology.

BACKGROUND: Vascularized composite allotransplantation has redefined the frontiers of plastic and reconstructive surgery. At the cutting edge of this evolving paradigm, the authors present the first successful combined full face and bilateral hand transplant. METHODS: A 21-year-old man presented for evaluation with sequelae of an 80 percent total body surface area burn injury sustained after a motor vehicle accident. 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 face and bilateral hand transplantation. 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 (i.e., eyelids, ears, nose, lips, and skeletal subunits) and bilateral hand transplantation (i.e., forearm level) was performed over 23 hours on August 12 to 13, 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 8 months, the patient was approaching functional independence and remained free of acute rejection. He had significantly improved range of motion, motor power, and sensation of the face and hand allografts. CONCLUSIONS: Combined face and bilateral hand transplantation is feasible. This was the most comprehensive vascularized composite allotransplantation procedure successfully performed to date, marking a new milestone in plastic and reconstructive surgery for patients with otherwise irremediable injuries.
