Objectives: Update on clinical results obtained by the first worldwide facial transplantation teams as well as review of the literature concerning the main surgical, immunological, ethical, and follow-up aspects described on facial transplanted patients.
Study design: MEDLINE search of articles published on “face transplantation” until March 2012.
Results: Eighteen clinical cases were studied. The mean patient age was 37.5 years, with a higher prevalence of men. Main surgical indication was gunshot injuries (6 patients). All patients had previously undergone multiple conventional surgical reconstructive procedures which had failed. Altogether 8 transplant teams belonging to 4 countries participated. Thirteen partial face transplantations and 5 full face transplantations have been performed. Allografts are varied according to face anatomical components and the amount of skin, muscle, bone, and other tissues included, though all were grafted successfully and remained viable without significant postoperative surgical complications. The patient with the longest follow-up was 5 years. Two patients died 2 and 27 months after transplantation.
Conclusions: Clinical experience has demonstrated the feasibility of facial transplantation as a valuable reconstructive option, but it still remains considered as an experimental procedure with unresolved issues to settle down. Results show that from a clinical, technical, and immunological standpoint, facial transplantation has achieved functional, aesthetic, and social rehabilitation in severely facial disfigured patients.
Key words:Face transplantation, composite tissue transplantation, face allograft, facial reconstruction, outcomes and complications of face transplantation.
In facial transplantation, preoperative planning is crucial to select an allograft whose anatomical compatibility with the recipient defect is as close as possible. The dimensions of the potential face donor must be congruent to ensure the procedure's feasibility and the adequate insertion of the allograft into the defect. The recording of anthropometric measurements with the virtual reality software displayed an equivalent correlation to those produced using a conventional analogue method. The 3D reconstructions obtained by using a virtual reality software can play a useful role to facilitate the characterization of the donor face.
Face transplant (FT) has evolved enormously in the last 10 years since the successful completion of the first facial transplant. This procedure has become a new reconstructive option for complex facial deformities to restore the anatomy of patients with severely disfigured faces. The authors review the literature and discuss the main surgical, immunological, and ethical aspects as well as the results described in patients undergoing FT. To date there have been more than thirty FT worldwide. The main indication was post-traumatic deformity. In all cases a standard immunosuppression was performed with three drugs, although acute rejection episodes were observed, that could be controlled with conventional immunosuppressive regimen. Overall, functional and aesthetic results have been excellent at short-term and high satisfaction rate exceeded initial expectations, although long-term data are still scarce. Major complications were opportunistic infections. Five deaths that occurred have reopened the ethical debate about the potential complications and concerns of providing informed consent to recipients. Continuous progresses in microsurgical techniques and preoperative planning have promoted the evolution from partial to full FT. All these are on the basis of accurate and careful selection of wellmotivated candidates. The next challenge will be getting new immunosuppressive treatment strategies. Although clinical experience has demonstrated the FT viability, it is still considered an experimental procedure in which we have much to learn to define its true role in the current reconstructive surgery and resolve major technical, medical and ethical problems involved.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
