At present, the material handling is still not fully mature, and the material has some absorption after operation, which is under study. The disadvantages of are: (1) Intraoperative shaping is required.Compared with silicone rubber, expanded polytetrafluoroethylene Gore-Tex as a rhinoplasty material has the following advantages:  (1) It is softer than silicone rubber and is more natural after surgery.

Rhinoplasty materials can be divided into three categories: autologous materials, foreign materials or heterogeneous materials, and tissue substitutes. It is non-toxic, non-carcinogenic, non-teratogenic.Rhinoplasty is one of the common operations in plastic and cosmetic surgery.(3) The tissue can grow into the material, and the long-term fixation is better.　　

Due to insufficient hardness, the effect of supporting the columella and tip of the nose is not good. There are two commonly used ones: willow-shaped ;-shaped.Rhinoplasty using tissue substitutes (biomedical materials) is currently the most commonly used method. Silicone rubber can be pre-made into nasal prostheses with various shapes and models such as nose tip, nose alar and columella.(3) It is necessary to prevent the appearance change before the postoperative healing.(2) There is no 'transparency' like silicone rubber.　　

PTFE is resistant to high and low temperatures, has good chemical stability, corrosion resistance, and histocompatibility. Rhinoplasty is only to improve appearance, not necessary to treat diseases, so it should be used with caution. The chance of getting out due to excessive tension is low. Autologous materials include autologous costal cartilage, iliac bone, etc.Allogeneic or xenogeneic materials refer to bone or cartilage materials of other humans or animals, such as cattle nasal septal cartilage.

After being implanted in the body, a mild transient inflammatory reaction appeared locally, and a thin layer of fibrous cyst was formed around it later. It is the most widely used BBQ grill mat Manufacturers and effective material in rhinoplasty. The disadvantages are surgical scars and structural defects in the sampling area, which are also affected in function., which have the advantages of no risk of rejection for life, and excellent compatibility with nasal tissues.

Once postoperative infection occurs, the prosthesis must be removed to cure. Commonly used materials (and prostheses) are introduced as follows: Silicone rubber has good elasticity, easy to shape, good chemical inertness, non-toxic, non-carcinogenic, non-teratogenic, and good histocompatibility.The requirements for surgical disinfection are more stringent
