Silicone prosthesis has good flexibility and elasticity, and strong stereoscopic effect. Moreover, silica gel itself has the basic shape of the nose, and it can be carved at will on the basis of it. Silica gel is made into various shapes, including nose tip, nose wing, nose column and so on. Generally speaking, the maintenance time of silicone rhinoplasty effect is related to the quality of silicone. If the prosthesis made of unqualified silicone is used for rhinoplasty, the postoperative maintenance time is not only short, but also harmful to human body. Therefore, good quality silicone materials must be selected for rhinoplasty. Generally, the service life of domestic silica gel materials is about 5- 10 years, and foreign silica gel materials can be used for a longer time. Moreover, once there is a problem after silicone breast augmentation, silicone can be taken out completely without affecting the tissue of the nose.
