Dr. Patrick Byrne is one of the world’s top plastic surgeons in the world and Sherrie’s doctor. He had the idea to grow a replacement ear on Sherrie’s arm. The doctor took tissue from her rib and molded it into the shape of an ear. The tissue was then put under the skin of her arm to grow for months. After the ear was ready, it was time to take it off her arm and put it on the side of her head.
