Facial vascularized composite allotransplantation has emerged as a groundbreaking reconstructive solution for patients with severely disfiguring facial injuries. The authors report on the first Canadian face transplant. A 64-year-old man sustained a gunshot wound, which resulted in extensive midface bony and soft-tissue damage involving the lower two-thirds of the face. In May of 2018, he underwent a face transplant consisting of Le Fort III and bilateral sagittal split osteotomies in addition to skin from the lower two-thirds of the face and neck. Virtual surgical planning was used to fabricate osteotomy guides and stereolithographic models. Microsurgical anastomoses of the facial (three branches) and infraorbital nerves were performed bilaterally. At 18-month follow-up, the aesthetic outcome was excellent. Partial restoration of light touch sensation had been observed over the majority of the allograft. Although significantly affected, animation, speech, mastication, and deglutition were continuously improving with intensive therapy. Nevertheless, the patient was now tracheostomy and gastrostomy free. Despite these limitations, he reported a high degree of satisfaction with the procedure and had reintegrated into the community. Four grade I episodes of acute rejection with evidence of endotheliitis were successfully treated. Postoperative complications were mainly infectious, including mucormycosis of the left thigh, treated with surgical resection and antifungal therapy. Undoubtedly, immunosuppression represents the greatest obstacle in the field and limits the indications for facial vascularized composite allotransplantation. Continuous long-term follow-up is mandatory for surveillance of immunosuppression-related complications and functional assessment of the graft.
面部血管化复合组织同种异体移植术已成为严重毁容性面伤患者的一种突破性重建解决方案。作者报告了首例加拿大面部移植术。一名 64 岁男子因枪伤导致广泛的面中部骨和软组织损伤,累及面部中下三分之一。2018 年 5 月,他接受了面部移植手术,包括 Le Fort III 和双侧矢状劈开截骨术,以及中下三分之一面部和颈部的皮肤。虚拟手术规划用于制作截骨导板和立体光刻模型。进行了面部(三个分支)和眶下神经的双侧显微吻合术。在 18 个月的随访中,美容效果极佳。观察到供体的大部分区域已经恢复了部分轻触觉。尽管受到明显影响,但在密集治疗下,面部表情、言语、咀嚼和吞咽功能仍在不断改善。尽管如此,患者现在已经无需气管切开和胃造口术。尽管存在这些限制,但他对该手术非常满意,并已重新融入社区。有 4 次 I 级急性排斥反应发作,伴有内皮炎的证据,这些反应都得到了成功治疗。术后并发症主要为感染性,包括左大腿的毛霉菌病,经手术切除和抗真菌治疗。不可否认,免疫抑制是该领域最大的障碍,限制了面部血管化复合组织同种异体移植术的适应证。必须进行持续的长期随访,以监测免疫抑制相关并发症和移植物的功能评估。
