What are the methods of rhinoplasty?

There are two kinds of rhinoplasty: transplantation and implantation. Transplantation refers to tissue transplantation, but it is basically not used at present because of the large rejection of xenogenic bone, difficult source and inconvenient treatment. The patient's own bone or cartilage (such as ilium? Pork ribs? Costal cartilage, etc. ) transplantation, no rejection reaction, knowledge can last for a long time, but bone harvesting surgery is painful, carving is difficult, and it will degenerate and deform after a long time, so if there is no special need, pottery is rarely used. Implantation refers to the method of implanting inanimate matter into human tissue after shaping.
