After the wound should be strictly disinfected, debridement and suture should be carried out to preserve the cartilage tissue as much as possible. For example, the skin is large and the cartilage is still intact. The pedicle flap or free flap can be transplanted from behind the ear. For example, some cartilage and skin are completely broken. The edge is wedge-cut, and the fine needle is used to suture the suture. The suture cannot penetrate the cartilage.

1. Auricle abrasion: It is a skin abrasion on the surface of the auricle, but it does not damage the subcutaneous tissue and cartilage.

2, ear canal scratch: our external auditory canal skin is very delicate, and the perichondrium is very tightly connected, less subcutaneous tissue, poor blood circulation, improper use of the ear can cause damage to the external auditory canal, infection, resulting in inflammation, ulceration, and even the external auditory canal Open your mouth and eat. Some people have itchy ears, and they use their hairpins, matchsticks, and ear spoons to cover their ears very deeply and hard.
