Ear cartilage rhinoplasty is a kind of autologous cartilage rhinoplasty, which uses human cartilage tissue to achieve a rhinoplasty effect. Autologous cartilage is hard and elastic, so it doesn't need a lot of blood vessels for nutrition, and it won't be affected if the tissue loses a part of cartilage. As a rhinoplasty material, auricular cartilage is usually used to pad the tip of nose. If the amount of material is appropriate, it can also be used as a material to cushion the bridge of the nose. Because the auricular cartilage of the auricular fossa will regenerate, and the incision is mostly in the hidden part, it is not easy to be found, so the auricular cartilage is often used as one of the plastic materials for rhinoplasty. The key to the use of auricular cartilage is that the operator must keep the perichondrium and only remove the cartilage, so as to ensure the regeneration of auricular cartilage. At present, ear cartilage is mainly used to pad the tip of the nose, which has good histocompatibility and stability. Easy to fix, no displacement and rejection, low absorption rate, is an ideal rhinoplasty material.
