　　Brenda Jensen said the operation was a great success which had saved her life．Thirteen days after the surgery she said her first words: "Good morning, I want to go home．"It is the first time a voice box and windpipe have been transplanted at the same time and only the second time a voice box has ever been transplanted．

　　Ms．Jensen, 52, had been unable to speak on her own since her voice box was damaged during surgery in 1999．Since then, she has been unable to taste or smell food, could breathe only through a hole in her windpipe and could talk only with the help of an electronic voice box．

　　Professor Martin Birchall from University College London, who was part of the surgery team, said: "We've learned that we can repair nerves to make even very complex organs function again． It'll open the door to better facial transplants and will be extremely important as tissue engineering develops．"
