Ethical considerations in face transplantation

Ethical considerations regarding penis transplantation surgery in transgender men-an empirical ethics study

Background

The ongoing quest to surgically create the (nearly) ideal neophallus in transgender men has led to the continuous development of transgender medicine and the proposed introduction of penis transplantation. However, both technical and ethical issues arise when developing this treatment.

Aim

We sought to extract ethical considerations among different stakeholder groups regarding penile transplantation surgery in transgender men and to define preliminary clinical recommendations.

Methods

Three semistructured focus groups, consisting of different stakeholders, were organized to participate in discussions of ethical considerations retrieved from the ethics literature of transplantation and transgender medicine. Analysis of the results was performed according to empirical ethics.

Outcomes

Study outcomes were the identification of qualitative themes describing ethical considerations pertaining to penile transplantation in transgender men.

Results

Nineteen people participated in this qualitative study. The main domains that emerged included arguments in favor of and arguments against penile transplantation. Although the participants expressed positive attitudes toward developing this care, with acknowledgement of the current limitations stakeholders of all groups were reluctant to endorse the introduction of penile transplantation for transgender men at this point.

Clinical Implications

Under the present circumstances, all groups expressed both a wide variety of ethical considerations as well as a tendency to prefer developing alternative treatment options or improving the results of currently available treatments in relation to penile transplantation for transgender men.

Strengths and Limitations

This study was the first (empirical) study to focus on this topic and included a diversity of stakeholder perspectives. Limitations included the hypothetical nature of the discussion as well as the clinical setting in which the topic has been studied.

Conclusion

Introducing penile transplantation for transgender men, under the current circumstances, comes with a wide range of ethical considerations, which deal with personal identity, autonomy, medical risks, risk for transgender support and donor willingness, and issues regarding equality. Despite the present hesitancy to use penile transplantation, should the technical side of this treatment option develop, further research in the ethical field of penile transplantation for transgender men is recommended.

Facial Transplantation: Complications, Outcomes, and Long-Term Management Strategies

Within the past two decades, vascularized facial composite allotransplantation has evolved into a viable option in the reconstructive surgeons' armamentarium for patients with extensive facial disfigurements. As it has expanded the frontiers of microsurgical reconstructive techniques, facial transplantation has come to garner widespread interest within both the medical community and the general public. The procedure has established itself as an amalgamation of the forefronts of reconstructive microsurgery, immunology, and transplantation science. Therein too lies its complexity as multifaceted scientific developments are met with ethical and social issues. Both patients and physicians are faced with the everlasting challenges of immunosuppression regimens and their inherent complications, long-term aesthetic and functional considerations, the role of revision procedures, and the inevitable psychosocial implications. This article reflects on the medical and surgical advancements in facial transplantation surgery and highlights anticipated future challenges. It aims to encourage discussion regarding anticipated barriers to current practice and suggest future directions as we transition into the next phase of facial allograft transplantation.

Before and After: What Has Changed in the Attitude of Turkish Society Regarding Face Transplantations?

Face transplantation is one of the most popular and controversial subjects of plastic surgery today. Although there are various surveys on the subject, there is no study comparing the past and the present social viewpoint and behavioral preferences for face transplantations across the world. In this study, we aimed to investigate the changes in the views of the Turkish society with respect to face transplantation from past to present. For this purpose, 1000 volunteer participants were questioned in terms of demographics and their perspective and preferences on organ and face transplantation. The results of the study were compared with the past data, and based on the results, the level of consciousness and awareness of the Turkish society about the subject has increased; the rate risk taking for immunosuppression has decreased, and instead, the rate of having an undecided stance has increased, and this attitude continues even if the risk is resolved. With these results, we can conclude that the greatest handicap for face transplantation in the Turkish society today is immunosuppression and the associated risks. We believe that new drug protocols and monitoring of patient outcomes for longer periods as well as more extensive clinical applications may be beneficial in addressing this issue.

The Ethics of Facial Allotransplantation: A Systematic Review

Supplemental Digital Content is available in the text.

Currently, there are more than 40 cases of facial allotransplantation performed by 13 different groups in 10 countries. Although it has become a potential option to reconstruct and restore the function and appearance of severely facially disfigured individuals, the ethical concerns of facial allotransplantation remain unsolved. We conducted a systematic review to better understand the ethical concerns on facial allotransplantation and the changing trends of the ethical debate over time.

Law and medical ethics in organ transplantation surgery

This article in the series describes how UK law and medical ethics have evolved to accommodate developments in organ transplantation surgery. August committees have formulated definitions of the point of death of the person which are compatible with the lawful procurement of functioning vital organs from cadavers. Some of the complexities of dead donor rules are examined. Live donors are a major source of kidneys and the laws that protect them are considered. Financial inducements and other incentives to donate erode the noble concept of altruism, but should they be unlawful?

A survey of North American burn and plastic surgeons on their current attitudes toward facial transplantation

BACKGROUND

Feasibility of composite tissue allotransplantation (CTA) has been substantiated by transplantations of the hand, abdominal wall, and face. CTA has the potential to reconstruct "like with like," but the risk-to-benefit ratio and clinical indications have yet to be determined. We sought to examine the current attitudes about the emerging field of CTA from those who treat complex facial injuries.

STUDY DESIGN

In 2007, a Web-based blinded survey was sent to both burn and plastic surgeons involved in facial reconstruction. We examined the practice profile with regard to complex facial injuries and asked respondents to assess the level of risk in CTA and indications for facial transplantation. Surgeons were asked to evaluate three clinical cases (two closely mirroring clinical face transplantations) for suitability for treatment with CTA.

RESULTS

One hundred sixty-four surgeons responded (54% response rate) and averaged 17.3 years in practice. They saw 12.1 severe facial-injury patients per year. A total of 78.7% agreed that current techniques do not provide adequate reconstruction for severe facial injuries, and 26.2% were in favor of performing CTA on immunosuppression. Acceptable indications for CTA were multiple failed reconstructions (70%), total facial burn (59%), and absence of remote tissue (55%). Ten percent saw no acceptable indication for CTA. The scenarios that mimicked recent transplantations had moderate support in favor of CTA (20.7% for the Chinese patient and 29.3% for the French patient).

CONCLUSIONS

This survey demonstrates support for use of CTA to reconstruct complex facial deformities. Surgeons continue to be wary of immunosuppression and chronic rejection, and many want to wait for better immunologic treatment options.

Some issues in facial transplantation

Human facial transplantation, a form of composite tissue allotransplantation, has now become a clinical reality. We carried out the world's second partial facial transplantation in April 2006. We reviewed some issues associated with facial transplantation, especially focusing on the individual who underwent the transplant in our department. We discussed surgical indications, techniques, risks versus benefits, informed consent and psychosocial, societal and financial issues of facial transplantation. In our opinion, with the progresses in composite tissue allotransplantation, partial or full facial transplantation is becoming a timely and effective remedy for the significantly disfigured patients. However, there are a lot of problems unsolved, and as we have performed the transplant on only three individuals, no long-term outcome data are available. Facial transplantation needs further research.

Human facial allotransplantation: a 2-year follow-up study

BACKGROUND

Progress in composite tissue allotransplantation could provide a new treatment for patients with severe facial disfigurements. We did a partial facial allotransplantation in 2006, and report here the 2 year follow-up of the patient.

METHODS

The recipient, a 30-year-old man from China, had his face severely injured by a bear in October, 2004. Allograft composite tissue transplantation was done in April, 2006, after careful systemic preparation. The surgery included anastomosis of the right mandibular artery and anterior facial vein, whole repair of total nose, upper lip, parotid gland, front wall of the maxillary sinus, part of the infraorbital wall, and zygomatic bone. Facial nerve anastomosis was done during the surgery. Quadruple immunomodulatory therapy was used, containing tacrolimus, mycophenolate mofetil, corticosteroids, and humanised IL-2 receptor monoclonal antibody. Follow-up included T lymphocyte subgroups in peripheral blood, pathological and immunohistochemical examinations, functional progress, and psychological support.

FINDINGS

Composite tissue flap survived well. There were three acute rejection episodes at 3, 5, and 17 months after transplantation, but these were controlled by adjustment of the tacrolimus dose or the application of methylprednisolone pulse therapy. Hepatic and renal functions were normal, and there was no infection. The patient developed hyperglycaemia on day 3 after transplantation, which was controlled by medication.

INTERPRETATION

Facial transplantation could be successful in the short term, but the procedure was not without complications. However, promising results could mean that this procedure might be an option for long-term restoration of severe facial disfigurement.
