At present, silicone, expanded polytetrafluoroethylene and other prosthetic materials have been widely used in rhinoplasty. However, due to the poor affinity between silica gel and the body, after being put into the body, the tissue will form a membrane around the silica gel, and the membrane will be stimulated by the outside world, and contracture will easily occur, which will lead to deformation and displacement of the prosthesis, and even exposed. Expanded polytetrafluoroethylene has a porous structure, it is not easy to be displaced after placement, the effect of filling the dorsum of the nose is very good, but due to the growth of the tissue into the body, if there is an infection, especially after the placement of the number of months of infection, it will bring some difficulties to the removal of the prosthesis. Nasal prosthesis deformation requires prosthesis removal and repair surgery, in the repair of prosthesis deformation technology, with autologous cartilage and autologous dermis is the most widely used, can be applied to nasal septum cartilage rhinoplasty. When the nasal septum cartilage is not enough to meet the needs of the use of the cartilage, it can be cut at the same time to remove the cartilage of the auricular cavity. When it is difficult to take out the prosthesis, autologous dermis can be covered with solid silicone prosthesis on the back of the nose, the advantage of which is that autologous dermis has a dense, strong and elastic structure, with a rich capillary network, which is conducive to survival. Through the package of autologous dermis, the thickness of the soft tissue of the skin is increased, so that the dorsum of the nose can be heightened.
