Abstract
Face transplantation is a new achievement of transplantation medicine and microvascular reconstructive plastic surgery. However, the initial ethical and technical debate was not less intense, which tried to balance advantages and disadvantages of face transplantation. It was clear from the initial discussion at the beginning of the year 2000 that certain cases could benefit for such an approach, although real functional outcomes lacked support from ethical committees. More than ever, a continuous surveillance and detailed outcomes are necessary to put into perspective the indications and contraindications of face transplantation.

OutcomesComplicationsRejectionImmunosuppressionThe modern history of vascularised composite tissue allotransplantation began in 1998, when the first human hand transplantation became a reality. Few years afterwards, in 2005, the first human face transplantation was attempted with success by Devauchelle and Dubernard in France.
Face transplantation is a new achievement of transplantation medicine and microvascular reconstructive plastic surgery. However, the initial ethical and technical debate was not less intense, which tried to balance advantages and disadvantages of face transplantation. It was clear from the initial discussion at the beginning of the year 2000 that certain cases could benefit for such an approach, although real functional outcomes lacked support from ethical committees. More than ever a continuous surveillance and detailed outcomes are necessary to put into perspective the indications and contraindications of face transplantation.
To date, 28 face transplantations have been performed worldwide. Medicine is an ever-evolving science, and as such, at the time this work comes to the public, it is certain that new and novel face transplantations shall be attempted. The reader is therefore advised to keep updated with VCA literature and from reports from the international society of hand and composite tissue allotransplantation. Face VCA refers to allografts that contain different tissues (bone, muscle, skin, fat, mucosa, vessels); they are vascularised by one or many vascular pedicles, and in order to survive, the same principles that apply to solid organ transplantation should be followed.
15.1 Worldwide Experience on Face Transplantation
Twenty-eight face transplants have been performed in seven countries (Table 15.1). The longest follow-up period accounts for 8 years (Isabelle Dinoire, Amiens team) with a total published survival rate of 89.3 %. Three patients have died (1 patient in China, 1 patient in France-Paris team, 1 patient in Spain-Valencia team). Table 15.2 depicts transplant characteristics. Fourteen different transplant teams have performed in total 17 partial-face transplants and 11 full-face transplants for a variety of aetiologies that include 10 postburn deformities, 8 gunshot injuries, 3 animal attacks, 4 type 1 neurofibromatosis, 2 posttraumatic deformities and 1 postoncological/radiotherapy deformities. After the transplantation of the first full-face transplant in 2010, the indications have expanded; however, a robust team approach and specific face VCA protocols are necessary to warrant correct outcomes. The indications for face transplantation vary among different VCA teams. In general terms, destruction of face sphincters (orbital and/or oral muscle sphincters) is a common indication for face transplantation (there currently does not exist a traditional technique that repair the function of such sphincters). Contraindications include significant medical co-morbidities, poor adhesion to medical follow-up, medical risk for immunosuppressant therapy (recurrent cancer, medical co-morbidities regarding past medical history) and psychological/psychiatric instability. Most of the patients have undergone previous reconstruction by traditional techniques, although there is intense debate whether face transplantation should be performed early in the hospital course to leave intact other traditional techniques and donor sites should the transplanted graft failed. Most of the teams performed procurement on a brain-dead heart-beating donor. Some teams advocate to procure the face before the rest of the solid organs are approached, although synchronous procurement is feasible, as it has been reported by our team. It is imperative to reduce cold ischaemia time during VCA. Some teams procured the face VCA at the end of the procedure (i.e. Chinese, Valencia’s, and Seville’s teams); this approach, though, may lead to a massive haemorrhage after revascularisation and increase the risk of ischaemia–reperfusion injury.
