A UK team has been given permission to carry out what would be the world's first full face transplant. Peter Butler at London's Royal Free Hospital said he was "delighted" to get the go-ahead from an NHS ethics board for an operation "within months". No patient has been selected for the procedure, although the team has been approached by about 30 patients. Last November Isabelle Dinoire from France became the first person to receive a partial face transplant. She had her nose, lips and chin torn off after being mauled by the family dog. Mr Butler said the go-ahead for the first full face transplant "had been a long journey, but this is just the beginning, really". "The most important part of the process starts now, which is selection of the patients," he added. Mr Butler is now looking to draw up a shortlist of candidates who meet the selection criteria for the operation, which includes an assessment of how they will deal with its psychological impact. His team will select four patients from the UK or Ireland for the procedure, and the operations will be carried out at six month intervals. He said he would not be able to carry out the operation on children, because of issues of consent.
