Ear plastic experts pointed out that appendages were formed during embryonic development due to the overgrowth of the first cheek, which belongs to a congenital malformation. Appendages vary in shape and size, and most of them also contain cartilage tissue, some of which are connected with ear cartilage, and some of which extend into the subcutaneous tissue of cheek or deep above parotid fascia. 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 often several cartilage tissues in the tissue, and the skin surface sometimes has color. It is completely redundant and has nothing to do with hearing and other functions. Although sometimes the ear cartilage can be connected with the ear cartilage, and sometimes it extends into the cheek tissue, it is useless tissue. Appendectomy is simple and short, and the scar will gradually disappear in a few days after operation.

The treatment of auricle is to remove the auricle and the cartilage tissue contained in it, and adjust the wound suture appropriately. Patients with adnexal ears are often accompanied by ipsilateral hypoplasia, so when removing cartilage, only the convex part can be removed, and the subcutaneous part of the face can be preserved, so as not to aggravate facial deformity. For the appendage in front of the tragus, it can be used to reconstruct the tragus after resection. The formation of appendages is due to the 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 often several cartilage tissues in the tissue, and the skin surface sometimes has color.

Ears, also commonly known as "tying horses", are not valued by many people in life. Some people think that they are auspicious symbols, but more people think that they hinder aesthetics. In fact, from a medical point of view, appendages are mainly caused by abnormal development of the first branchial arch. Our external ear is formed by the first and second branchial arches in embryonic period. If the first branchial arch develops abnormally, there will be auricles. Therefore, under normal circumstances, the auricle presents redundant tissues of different sizes and shapes on the connection line between the tragus and the corners of the mouth. There are often many cartilage tissues in the tissue, sometimes accompanied by preauricular fistula.

It can be said that appendages are completely redundant tissue parts, because the development source of inner ear is different from that of outer ear, so appendages often only affect facial appearance, and have nothing to do with hearing and other functions. Judging from the timing of the operation, the appendage is only for beauty, so it can be removed at any time.
