A new type
of transplant which would see a donor's face grafted on to a recipient
could be medically possible within six to nine months, according
to a leading British plastic surgeon.
Dr. Peter
Butler of the Royal Free Hospital in London told the British Association
of Plastic Surgeons that it was essential that an ethical debate
take place before anyone undergoes the surgery.
"It's
not, 'Can we do it?', but 'Should we do it?'" said Butler.
"The technical part is complex but I don't think that's the
thing that's going to be the very great difficulty. It's the ethical
and moral debate that's going to have to take place before the
transplant takes place."
Butler said
patients who have suffered severe facial burns, cancer patients
who've had facial surgery or people disfigured in accidents could
benefit from the surgery, and the first candidates might be young
children.
"I am
told that the age at which children first recognize themselves
is between five and six," Butler said. Doctors said an adult
acquiring a new face would have to cope with a major psychological
and emotional challenge.
The microsurgical
procedure would involve removal of the the patient's face, facial
muscles, skin and subcutaneous fat, which would be replaced with
that of a cadaver donor. Blood vessels, arteries and veins from
the donor would then be connected to the patient's vessels with
microscopic stitches, along with the nerves.
While the
patient would acquire the skin tone and texture, eye brow color
and eyelids of their donor, the recipient would retain his or
her own bone structure.
"It is
like any other organ transplant because you can actually do it
and achieve it with modern immunosuppression," Butler told
the BBC. "But it is different because it is visible and it
is part of our expression."
A British
Department of Health spokesperson said that before the transplant
could occur, the procedure would have to be examined by an advisory
committee of the National Institute for Clinical Excellence.
Face transplants
until now have occurred only in science fiction, forming the basis
of the 1997 film "Face Off," starring John Travolta
and Nicolas Cage, in which a criminal and detective swapped faces.
