There are three main types.

① Silicone prosthesis: made in China and imported from Korea, widely used in plastic surgery. It has good biocompatibility, stable properties, easy molding, no toxicity, no teratogenic effect and ideal rhinoplasty effect. It is also the first choice for rhinoplasty in plastic surgery institutions all over the world, with reasonable price, simple acquisition and one-step molding.

(2) PTFE: It is a porous solid material with many micropores, which is extremely stable in performance, soft in texture, easy to carve, realistic in shape and not easy to scrap.

③ Autologous cartilage: It has no rejection to autologous tissue. This method of rhinoplasty is suitable for the overall shaping of nose shape and the special shaping of nose tip. It has the best compatibility with nasal tip cartilage and is the most realistic. When the nose changes from low to high, it is necessary to bury a certain thickness of filler in the tissue of the nose. This filling is called a prosthesis. Prosthesis must be made of materials that are harmless to human body, have no rejection, do not deteriorate for a long time, have certain elasticity, are easy to shape and take out.

In the early cosmetic surgery, people used paraffin, tortoise shell, fish bones and animal bones for rhinoplasty. Practice has proved that these materials will produce various adverse reactions after being implanted into human body, so they have been abolished. Later, German doctors used ivory rhinoplasty to achieve good results, which once attracted people's attention. However, ivory is rarely used because of its excellent texture, time-consuming processing and difficult source.

After World War II, with the development of chemical industry, people gradually paid attention to synthetic materials. At first, some people used synthetic resin material for rhinoplasty, but this material was quickly eliminated because of its brittle and hard texture, easy fracture and light transmission. Later, people gradually turned their attention to flexible silicone products. At first, industrial black silica gel was used, but because of the color problem, the injection method was backward and the postoperative effect was not ideal. Mixed liquid injection and liquid silica gel injection were once popular, but in the end they were eliminated because the surgical effect was not ideal and the stimulation to human tissues was not good.

At present, DMPR based on silicon is used internationally. The material is harmless to human body, easy to process and shape, soft and firm in texture, and does not deteriorate for a long time, so it is an ideal filling material for cosmetic surgery. At present, hospitals all over the world will make various silicone models of rhinoplasty according to doctors' habits, and then modify the models according to the specific conditions of each patient, and directly use them for surgery after strict disinfection.
