Composite tissue transplantation in reconstructing complex facial defects has developed tremendous interest over the recent years, since the first report of partial face transplantation performed in France in 2005. However, the controversy over the ethical, immunological, and psychological issues remains. Recently, we obtained IRB approval to perform partial face transplantation at Brigham & Women's Hospital, Boston. Here we present the rationale and IRB application process of our unique approach to this highly controversial procedure, which focuses on partial face transplantation on patients currently on immunosuppressants due to previous transplanted organ. 'Patient selection criteria', selection process, technical and immunological protocols are discussed. We currently share the concern that life-long immunosuppression associated with facial transplantation may not outweigh its benefits as compared to the alternative reconstructive methods. We asked ourselves the question of which patient population would risk less and overall benefit more from undergoing face transplantation, and identified those currently on immunosuppressive therapy the most suitable candidates. Organ transplant recipients are at increased risk of malignancy, particularly skin cancer commonly located in the facial region, necessitating surgical resection and facial reconstruction. They also have to take immunosuppressants to prevent rejection of their primary transplanted organ, which will minimize the need for additional immunosuppression associated with facial allograft. Being a previous organ recipient also diminishes the difficulty of complying with the strict postoperative immunosuppressive regimen, commonly encountered by organ transplant recipients. This approach could be very beneficial for previously immunosuppressed patients and perhaps take its place in our reconstructive ladder options.
自2005年法国首次报道部分面部移植以来,复合组织移植在重建复杂面部缺损方面近年来引起了极大的关注。然而,关于伦理、免疫和心理问题的争议仍然存在。最近,我们获得了美国波士顿布莱根妇女医院机构审查委员会(IRB)的批准,开展部分面部移植手术。在此,我们介绍我们针对这一极具争议性手术的独特方法的基本原理和IRB申请过程,该方法专注于对因先前接受过器官移植而正在服用免疫抑制剂的患者进行部分面部移植。我们讨论了“患者选择标准”、选择过程、技术和免疫方案。我们目前也担心,与面部移植相关的终身免疫抑制与其他替代重建方法相比,其益处可能并不显著。我们问自己,哪类患者群体接受面部移植的风险更小且总体获益更大,并确定目前正在接受免疫抑制治疗的患者是最合适的候选人。器官移植受者患恶性肿瘤的风险增加,尤其是面部常见的皮肤癌,这就需要手术切除和面部重建。他们还必须服用免疫抑制剂以防止对其原发移植器官的排斥反应,这将减少与面部同种异体移植相关的额外免疫抑制的需求。作为先前的器官接受者也降低了遵守器官移植受者常见的严格术后免疫抑制方案的难度。这种方法可能对先前接受过免疫抑制治疗的患者非常有益,并且可能在我们的重建阶梯选择中占有一席之地。
