Plastic surgeons from a hospital in Xi’an, capital of
northwest China’s Shaanxi Province, have successfully transplanted a
regenerated ear from a patient’s arm to his head.
The patient, whose surname is Ji, suffered severe injuries
on the right side of his face and lost his right ear in a traffic accident over
a year ago.
As it was impossible to regenerate another ear over the
scar, Guo Shuzhong, a leading plastic surgeon at the First Affiliated Hospital
of Xi’an Jiaotong University, decided to “plant” an ear on Ji’s forearm and
then transplanted it to his head.
The plastic surgery was divided into three stages. During
the first stage, a skin expander was set in Ji’s right forearm. In the second
stage, doctors extracted cartilage from Ji’s rib and carved it to build the new
ear. The cartilage was then planted under the expanded skin on the patient’s
arm, allowing the new ear to grow.
Guo and his colleagues performed the third stage of the
plastic surgery on Wednesday when they successfully transplanted the
regenerated ear onto Ji’s head using microsurgical techniques. The operation
lasted seven hours.
After the surgery, the newly transplanted ear appeared pink
in the light of the operating room lamp. Guo and his colleagues heard the sound
of bloodflow using a Doppler blood vessel detector, indicating the surgery was
successful.
Guo said the surgery was very difficult because they had to
transplant the regenerated ear to an appropriate place on the head that could
supply adequate blood flow to the ear to ensure normal functioning after
surgery.
The patient is in stable condition. He will be discharged
from the hospital in about two weeks when his new ear can work normally.
Guo and his colleagues also used 3D printing technology to
make the regenerated ear look more realistic. Guo and his team create regenerated ears for about 500
children each year.
