A woman has a new ear, thanks to a mind-blowing procedure performed at Johns Hopkins.
42-year old Sherri Walter had cancer on her ear and it had to be removed, as well as many of the structures inside her head.
Doctors decided to make her a whole new ear.
They took cartilage from her ribs and they shaped it into an ear. They then took that cartilage and put it under her forearm.
