A team of 30 Spanish doctors claim to have successfully performed the world's first full face transplant.
The ground-breaking operation was carried out last month in Barcelona on a man whose face had been disfigured in an accident.
While face transplants have been carried out in the past they have only ever been partial.
The unnamed patient has received an entirely new face, including skin, muscle tissue, lips, nose, jaw, teeth, and cheek bones.
The patient's face was injured in an accident five years ago which left him unable to swallow, speak, or breathe properly.
The patient contacted surgeons after being inspired by the case of Isabelle Dinoire, the French woman who received the first partial face transplant in 2005.
