Looking at the development of rhinoplasty materials, the most ideal and safest rhinoplasty material is its own cartilage, that is, autologous cartilage. Ear cartilage and nasal septum can only be used for nasal tip plastic surgery because of limited bone sources. Ear cartilage can be used to raise the tip of the nose and increase the curvature of the tip. The cartilage of nasal septum is used to raise and lengthen the columella of nasal tip; Costal cartilage can improve the bridge of nose and tip of nose at the same time because of the limited bone source. Nasal septal cartilage augmentation rhinoplasty refers to a plastic and cosmetic operation with autologous nasal septal cartilage transplantation as rhinoplasty material.
