Surgeons Rebuild Iraq War Veteran's Entire Nose Using His Own Body Parts
05/23/07
Technology, developed for surgery after nasal cancers, used in multiple reconstructive operations on 23-year-old whose face was
disfigured.
It took only seconds for the Humvee to flip over and crash on a highway
near Camp Bucca in southern Iraq in August 2005. The force of impact
was blunted by the body armor protecting Senior Airman Michael Fletcher.
But his gear was not strong enough to stop the wreck from crushing the
rest of him. His left arm was gone, and along with it a sizeable chunk
of his midface, including his nose.
Fletcher remembers little of the disfiguring accident that nearly
killed him, but he likes to recall shopping in January 2007 near his
home on Andrews Air Force Base in Maryland.
Nobody stared at his torn face, he says. Not anymore, that is, because
of his *brand-new nose.*
In a series of six operations over a year-long period that ended with
removal of the last sutures on May 2 - and that rank as one of the most
complicated nasal reconstructions ever performed at Johns Hopkins -
facial plastic and reconstructive surgeons have pieced together more
than a dozen bits of bone, cartilage, skin, arteries and veins to
rebuild Fletcher*s nose. All materials were taken from spare or
renewable parts of his own body.
Fletcher*s new nose is completely functional. He can breathe and
sneeze through it, and expectations are that he will soon be sensitive
to smell and touch, his surgeons say.
Scarring and swelling will naturally reduce for a year, while minor
sculpting and contouring procedures are done at an outpatient clinic,
but his long days recuperating in the hospital are done, says lead
surgeon Patrick J. Byrne, M.D.
Aided by new advances in instrumentation by biomedical engineers, and
computer-assisted design of precision plastics for use as templates,
Byrne*s team and the patient logged more than 40 hours in surgery,
with the first operation, July 18, lasting eight hours. With his wife,
Yolanda, by his side the entire time, Fletcher had more than 60 hospital
check-ups and tests and needed three hospital stays, including a 16-hour
emergency operation to deal with a wound infection.
*This soldier is fearless,* says Byrne, an assistant professor in
otolaryngology - head and neck surgery at The Johns Hopkins University
School of Medicine. *From the beginning, his nasal reconstruction was
not straightforward. He had tremendous scarring all over his face and
head injuries so severe that I did not think he would go through it.
But he did not want to wear a prosthesis. He wanted his nose rebuilt,
even if all the world was going to see his scars.
*And there was significant risk that any transferred tissue would not
survive. It could get infected and have to be removed, adding scar
tissue and leaving us back where we started,* he says, recalling the
courage of his patient.
Hospital records show that Fletcher*s new nose involved more than 40
Hopkins clinical staff. Among them are an anaplastologist, who helped
design the shape and look of the new nose, several anesthesiologists,
operating room nurses, schedulers, and home care assistants, as well as
a team of surgeons from the United States military who initially treated
Fletcher in Kuwait and then at Walter Reed Army Medical Center, in
suburban Washington, D.C.
A Walter Reed surgeon who had trained in facial plastic surgery at
Hopkins, and who was familiar with Byrne*s recent work with cancer
patients, referred Fletcher to Hopkins in January 2006 for the
reconstruction.
The plan to rebuild Fletcher*s nose was based on techniques already
used to help survivors of nasal cancers resume a normal life without
disfigurement. Though rare, these cancers are often fatal without
surgery to remove tumors. Some cases require total removal of the nose.
Complicating Fletcher*s case was the soldier*s damaged facial
skeleton, which had little bone structure to support a new nose, and a
sparse network of facial arteries to sustain the highly vascularized
nasal tissues. Arteries supplying blood to the forehead had been
slashed in Iraq, potentially compromising the suitability of the skin
for subsequent transplant to the nose. The accident had also fractured
Fletcher*s skull, blinded his left eye, and widened the gap between
his eyes, something surgeons had to correct to properly place the nose.
Fletcher is also African American, so surgeons were compelled to
minimize risk of scarring, as any scar tissue would contrast sharply
with his dark skin.
Among the many procedures was the detachment on Dec. 20 of a forehead
flap of skin that now makes up the outer skin of the new nose. The flap
was first carved in upside-down profile on the center of his forehead,
with the top portion then cut out, turned around clockwise, and laid
over the newly rebuilt nose.
The outer skin covering was left attached to the center spot of the
forehead, right between Fletcher*s eyes, for six weeks to secure its
blood supply during recovery. While attached, the forehead flap was
covered with a protective bandage to prevent infection. Surgeons had
earlier made small incisions across the skin graft to promote new blood
vessel formation, and to improve the covering*s arterial network
before transplant.
The inside nasal components were assembled in two operations, with
nostrils and tip, using skin transplanted from his arm and neck, bone
and cartilage came from rib and ear.
One of the more complex procedures involved transfer of soft skin from
the underside of Fletcher*s arm to create an inside nasal lining.
Arteries in his neck had to be rerouted to keep sufficient blood flowing
to this part of the nose.
Weeks before the first operation, the surgical team fully mapped out
Fletcher*s interior and exterior skull, including his nasal passage,
by CT scan and nasal endoscopy.
Unique to the Hopkins approach is the additional use of clear plastic
molds that are custom-made to help surgeons shape the skin flap, build
up supporting cartilage, and construct the nose. (A mesh made of
different plastic is also often used as an alternative support structure
in cancer patients. Sometimes left inside the body, the mesh is
resorbed - chemically broken down and disposed of naturally, over time.)
Design and production of the nasal surgical guide began more than three months before Fletcher*s first surgery.
Hopkins anaplastologist Juan Garcia, M.A., a trained medical
illustrator who specializes in facial prosthetics, met with Fletcher
and, together, using old pictures of the soldier taken before his
accident as a reference, they designed his new nose.
Garcia, an assistant professor in art as applied to medicine, at
Hopkins, also took a silicone impression of Fletcher*s damaged midface
and created a stone model of the damaged terrain on which his new nose
would be built. On to this base, the artist applied hot wax and
sculpted a replica of the soldier*s nose, something he has done many
times before when making prosthetic noses, ears, and even eyes. The
modeling process took more than two hours and required dozens of minute
touch ups.
Once fitted, Fletcher*s wax replica and stone model were each scanned
by a computer to create a 3-D image needed to produce the plastic guide.
The methods for using laser scanning and computer software necessary to
produce the surgical tool were developed by Byrne and Garcia with a
local digital imaging firm, Direct Dimensions of Owings Mills, Md.
After making the computerized version of the surgical guide, the
resulting 3-D image was sent to the Berger laboratory at the United
States Army*s Aberdeen Proving Ground, in Gunpowder, Md., for
fabrication into a plastic version. The lab specializes in
manufacturing precision plastics for the military and private industry,
including the kinds of clear plastic molds that Byrne has used to
reconstruct noses for a half-dozen cancer patients.
*We know that our part in his recovery is just a single step
forward,* says Garcia. *But we are grateful to have been able to
help and wish him well. He is someone with a tremendous amount of
courage.*
Fletchers*s surgery was paid for by his military health insurance
plan. In addition to Byrne and Garcia, facial plastic surgeons involved
in Flether*s care were Chris Cote, M.D., and Kofi Boahene, M.D.
