Accessory ear is also called auricle, commonly known as microtia, which is caused by abnormal development of the first branchial arch. Usually there are redundant tissues of different sizes and shapes on the connection line between the tragus and the corners of the mouth. There are usually many cartilage tissues in the tissue, and the surface skin is sometimes colored. Accessory ear is a completely redundant tissue part, which has nothing to do with hearing and other functions. Although sometimes the accessory auricular cartilage can connect with the auricular cartilage and sometimes extend into the cheek tissue, it is useless tissue. It is a natural defect to have such a piece in front of the ear. Although it doesn't hurt, most people ask for surgery because it affects their faces. Surgery only needs to remove this vegetation protruding from the skin. Unless there is preauricular fistula at the same time, there is generally no need to dig deep into cartilage roots. The operation is simple and short, and the scar will gradually disappear within a few days after operation. The accessory ear is only removed for beauty, so it can be removed at any time. However, the removal of the accessory ear is a local anesthesia operation. If the child wants to do it, it is best to wait until he is 7-8 years old and can cooperate with the operation. In addition, for some people, having a pair of ears is a kind of mental stress, and doing it as soon as possible may help to reduce the psychological burden. Surgical method: only the fleshy vegetation and cartilage contained in the accessory ear need to be removed during the operation.
