Autologous cartilage rhinoplasty is a kind of nasal plastic surgery, which uses human cartilage tissue to achieve a rhinoplasty effect. Autologous cartilage is hard and elastic, and it doesn't need a lot of blood vessels for nutrition, and losing a part of it won't bring great functional loss to people, so it has become an important source of autologous rhinoplasty materials. The majority of beauty lovers must know what surgical plan they are suitable for before choosing a rhinoplasty method, and choose a regular medical institution to avoid rhinoplasty failure as much as possible. Autologous cartilage rhinoplasty is the most popular one. The cartilage commonly used in rhinoplasty is auricular cartilage, nasal septum cartilage and costal cartilage. These three materials have their own advantages and disadvantages. 1, auricular cartilage: The auricular cartilage behind the auricular fossa is used for rhinoplasty. The auricular cartilage behind the auricular fossa will regenerate, and its appearance will not change. The wound can be hidden behind the ear and is not easy to be found. The thickness of the ear cartilage is just right for the tip of the nose. The tissue compatibility of auricular cartilage transplantation is good and stable, and it can heal with the local tissue of nose, and it is easy to fix without displacement and rejection. It is also very convenient to obtain, easy to carve and trim the shape, and is an ideal rhinoplasty material. 2. Nasal septal cartilage: Nasal septal cartilage is a plate-like cartilage that separates the two nasal cavities. When the front and upper parts of it are removed integrally, the nose shape can be kept intact and the required materials can be obtained. Moreover, the material selection and rhinoplasty are in the same incision, so it is really a strategy of "killing three birds with one arrow". For example, the nasal septum can be extended for transplantation, and fixing it in front of the nasal septum can make the tip of the nose move forward and downward, thus solving the problems of "nose facing the sky" and "nose dew". 3, costal cartilage: mainly solve the problem of difficult nasal plastic surgery. For some Asians whose noses "collapse" badly, the development of nasal septum is not perfect, but it is also this group of people who need "parts" more. Costal cartilage, as another representative of hyaline cartilage, has a wide range of sources, reliable texture and safe sampling method. But also the "ultimate weapon" for all kinds of congenital nasal deformities, acquired nasal deformities caused by trauma or surgery.
