Rhinoplasty is a kind of plastic surgery. Many people hope to have a strong nose through rhinoplasty. Rhinoplasty should be a relatively simple operation, but as long as it is an operation, it will fail. When the postoperative shape and height are inappropriate, the implanted prosthesis is skewed or translucent, and the skin changes or surgical traces are obvious, repair surgery is often needed. The repair operation of failed rhinoplasty refers to the operation of filling the nose with autologous, foreign tissue or tissue substitutes to cushion the external nose and improve the appearance of the nose. There are two kinds of rhinoplasty incisions: columella incision and intranasal incision, among which the intranasal incision (near columella) is widely used because the incision is hidden and there is no trace on the outside.
