Despite his perhaps bizarre
appearance, a man in China who is growing a new nose on his forehead is the
beneficiary of a rather common nose reconstruction technique.
The man suffered damage to his
nose and an infection after a severe car accident, and the infection had eaten
away at the cartilage in his nose, making it impossible to for doctors to fix
his original nose.
Instead, the team decided to grow the man an
entirely new nose on his forehead, But
despite its extreme appearance, this method is really just a variation of
plastic surgery techniques used all the time, said Dr. David Cangello, an
attending plastic surgeon at Lenox Hill Hospital and Manhattan, Eye Ear and
Throat Hospital in New York.
"I would call it a different take on a principles that we commonly
use in re-construction," Cangello said.
Forehead nose
The man's doctors placed tissue expanders, which create space to
stretch the skin, under the man's forehead, and created the rough shape of a
nose. They then harvested cartilage from his ribs to create a frame for the
nose, probably using screws and plates. Once the nose is ready, they will
rotate the entire assemblage — skin, blood vessels, cartilage and all — and
move the new nose to where his current nose sits.
That is only slightly different from current methods of nose
reconstruction, Cangello told. Though reconstructive surgeons would also put
tissue expanders under the forehead skin to stretch the skin enough to cover
the new nose, they would place the nose differently.
"We typically take the cartilage from the rib, and we put it right
where the nose structure would already be, and we bring the skin flap over it
and cover it," Cangello said. caribbeanmedicalschools.com
Afterward, the doctors suture together the skin flaps of the forehead
or leave the skin to heal on its own, which will usually leave a small scar.
Key blood
vessels
Though it may seem like a patient might prefer to grow a new nose on a
different part of the body that could be more inconspicuous, there are good
reasons to use forehead skin.
"Skin that comes from another area of the face will most resemble
the skin of the nose, as opposed to skin that came from another body
part," Cangello said. caribbeanmedicalschools.com
The forehead also has blood vessels that nourish the tissue transplant,
so the surgeons don't have to disconnect and reconnect those vessels to place
the nose in its correct position. If the doctors were to grow the nose on a
forearm or a leg, for instance, they would have to undertake a laborious
microsurgery to take the blood vessels that feed and drain the transplant.
Better nose?
The man still seems to have a nose that, at least in pictures, looks
fairly normal. By contrast, his replacement nose is pretty large.
But the new nose should contract to some extent once it's in place, he
added.
It's also possible the researchers needed to replace the man's current
nose because he had trouble breathing properly. caribbeanmedicalschools.com
"Whenever we perform a reconstruction, there are two things in
mind," Cangello said. "It's not just form, but it's also
function."
