US doctors have carried out what they say is the most extensive face transplant ever performed.
The operation at the University of Maryland gave Richard Norris a new face, including jaw, teeth and tongue.
The 37-year-old has lived as a recluse for 15 years after being severely injured in a gun accident, and wore a mask whenever he went outside.
The surgery was funded by the US Navy, which hopes the techniques will help casualties from Iraq and Afghanistan.
Surgeons who carried out the 36-hour operation say it was part of a series of transplant operations lasting 72 hours, using organs from one donor in five patients including Mr Norris.
