US doctors have carried out what they say is the most extensive face transplant ever performed, BBC reported.

The operation at the University of Maryland gave Richard Norris a new face, including a 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.

The lead surgeon says Mr. Norris will now get his life back. He is now brushing his teeth and shaving, and has regained his sense of smell.

据英国广播公司报道，美国医生完成了他们认为迄今最全面的脸部移植手术。

美国马里兰大学为理查德·诺里斯做了这次手术，为其换了一张全新的面孔，包括下巴、牙齿和舌头。

在一次枪击案中诺里斯遭受重伤，37岁的他15年来一直过着隐居的生活。只要外出，他就会带上面具。

这次手术由美国海军资助，军方希望此技术可以帮助伊拉克和阿富汗战争中的受害者。

主治外科医生表示，诺里斯如今可以重获新生。他现在可以刷牙、刮胡子和重新拥有嗅觉。
