If the deformity is serious and total ear reconstruction is needed, it is recommended to operate at the age of 15, because the operation needs to take its own costal cartilage as the external ear bracket. The older you get, the more calcified the costal cartilage is, and the more difficult the operation is.
If the shape of the external ear is acceptable, total ear reconstruction and rib reconstruction are not needed. It can be used at any age, but the older you are, the greater the negative psychological impact on your child.
You can go to the Plastic Surgery Hospital of Chinese Academy of Sciences or the Plastic Surgery Department of Shanghai Ninth People's Hospital (ear reconstruction specialist clinic every Friday).
