Is there a cure for this birth defect/ genetic disorder?
Microtia repair surgery generally begins when the child is about 5 to 7 years of age. There are several procedural options, but a rib graft is the most common approach to reconstruction. It requires several steps, first, cartilage is removed from the child's rib. Next, the cartilage is placed beneath the skin and formed into the shape of a "normal" ear. And then skin graft will cover the cartilage.
