1, cartilage rhinoplasty materials mainly include costal cartilage, auricular cartilage and nasal septum cartilage.

2. Generally, nasal septum cartilage is chosen instead of ear cartilage, because nasal septum cartilage is relatively straight and has strong supporting force, and it is more suitable for cartilage scaffold for nasal tip plastic surgery, which can adapt to different situations, for example, some people need to raise the nasal tip, and some people need to extend the nasal tip and so on. The material of auricular cartilage is mainly to increase the height and length of the nasal tip if necessary after the nasal tip bracket is completed. At the top of the nose, there are two pterygoid cartilages, so the natural skin surface of the nose is two points, not one. Third, costal cartilage costal cartilage transplantation is a common nasal plastic surgery method used by international nasal tip plastic surgeons. It is mainly suitable for patients with poor conditions and high requirements, and sometimes it can be used to repair failed operations with great difficulty.

3. The postoperative wound should be kept clean and dry, and the dressing accessories should not be removed at will. Because there are many bacteria in the nasal cavity, the nostril incision should be kept clean before suture removal and disinfected four days before operation to prevent infection.
