Doctors in the United States say a man given a face transplant after living as a recluse for 15 years is recovering well.
Richard Lee Norris, 37, suffered horrific injuries including losing his lips and nose in a gun accident and wore a mask whenever he went outside.
Last week, more than 150 doctors and medical staff were involved in transplanting a face from a donor.
Surgeons who carried out the 36-hour operation said it was part of a series of transplant operations lasting 72 hours, using organs from one donor in five patients, including Mr Norris, the BBC reports.
Mr Norris was given new upper and lower jaws, a transplant of teeth, a portion of the tongue and all facial soft tissue from his scalp to his neck.
Surgeons have been amazed by his progress - he is already able to taste, smell, shave and brush his teeth.
The transplant surgery was funded by the US Navy, which hopes the techniques will help casualties from Iraq and Afghanistan.
The first face transplant was performed in France in 2005 on a woman who was mauled by her dog.
In 2010 surgeons in Spain carried out the world's first full-face transplant.
