Paris ? Doctors have performed another face transplant. This time they gave a 29-year-old man a new nose, mouth and chin and sections of his cheeks.

The man was disfigured by a genetic disorder and is the third person to undergo a partial face transplant.

“The patient is doing well from a surgical point of view,” said Dr. Laurent Lantieri. Still, he added, “We will have to wait many months for the results.”

The patient suffered from neurofibromatosis, which causes tumors to grow on nerve tissue throughout the body, doctors said. The condition is similar to the disorder that affected Joseph Merrick, who was depicted as “The Elephant Man.”

The patient had undergone about 30 or 40 surgeries in 10 years to try to improve the appearance of his face, Lantieri said. The tumors on his lips had grown so large that he could no longer eat properly or speak easily, Lantieri said.
