The auricular cartilage in rhinoplasty is mainly taken from the concha cartilage, because the auricular cartilage in the auricular fossa will regenerate, its appearance will not change and the wound can be hidden behind the ear, which is not easy to be found. However, the key point of taking auricular cartilage is that the surgeon must keep the perichondrium and only take cartilage, so as to ensure the regeneration of auricular cartilage. Liu Yanjun, a rhinoplasty surgeon, said that rhinoplasty with auricular cartilage is a very safe operation for skilled doctors. There is only a little cartilage tissue in the ear after excision, which will heal and regenerate slowly with time, and it has no effect on the ear, and the wound is hidden behind the ear and is not easy to be found.
