The auricular cartilage is the most important cartilage reservoir for rhinoplasty. According to incomplete statistics, about 70% of rhinoplasty procedures take a certain amount of auricular cartilage as material, while complications are very minimal, with only common tissue grafting complications such as hematoma, infection, scarring, and mild contracture, and none of them have serious consequences. If the amount of cartilage taken is small, the bone can be taken by incision behind the auricle, at the cranial ear angle, with local anesthesia, and the length of the incision is about 1 cm, which can be injected with more anesthetic to make local support. After removing the lamellar cartilage, the bleeding should be carefully and adequately stopped to prevent the formation of a hematoma; after the procedure, a light pressure bandage should be applied and the ear from which the cartilage was removed should not be compressed while sleeping. If larger pieces of cartilage are to be obtained, it is more convenient to make an incision at the marginal turn of the earnail cavity; again, more anesthetic is injected to allow proper separation of the cartilage from the skin; post-operative dressing and compression are even more important, making sure that the skin on the anterior and posterior walls is well re-adhered and that no dead cavity or accumulated blood is left. Generally speaking, experienced surgeons will not affect the shape of the auricle after removing the cartilage after careful work. However, if too large a piece of cartilage is removed, especially if it is roughly removed across the different subunit structures of the ear canal, or if a hematoma or infection develops, some degree of auricular curl and deformity may result. Since only the auricle is manipulated during the removal of the ear cartilage, there will be no damage to the hearing, and this is something that candidates can be assured of.
