Autologous cartilage rhinoplasty: Autologous cartilage can be ear cartilage, nasal septum cartilage and costal cartilage, which has the advantages of no rejection and strong anti-infection ability. However, due to the limited materials, it is not easy to shape, and the transplanted bone is easily absorbed when it is not closely connected with the nasal bone. Autologous cartilage is generally used in nasal tip plastic surgery, and the nasal septum cartilage is taken to raise and lengthen the nasal tip.
