1, silicone rubber will be used as plastic material, because silicone rubber has good biocompatibility, no irritation to human tissues, no toxicity, no allergic reaction, little rejection reaction and good physical and chemical properties. In the process of contact with body fluids and tissues, it can maintain its original elasticity and softness and is not degraded. It is a fairly stable inert substance.

2. From the medical point of view, silica gel material is the most ideal substitute for biological tissue at present, which is mainly used for vascular reconstruction in human organ transplantation. Silicone material is compatible with human body, non-toxic, non-carcinogenic, non-allergic, and basically needs no replacement for life. Silicone prosthesis materials can be prefabricated prostheses of various shapes and models, such as nose tip, nose wing, nose column and so on. At present, there are two commonly used prostheses, one is willow-shaped and the other is L-shaped. Of course, although rhinoplasty is a simple operation, improper handling will increase the chances of postoperative displacement, skew, infection, rejection and even skin ulceration, necrosis and erosion.
