The materials of rhinoplasty include solid silica gel, artificial bone, autologous bone tissue, autologous cartilage tissue, liquid silica gel injection, swelling and so on. At present, the most commonly used rhinoplasty material is solid silica gel, which has good biocompatibility, soft feel and low price, and is one of the first choice rhinoplasty materials in clinic.

Expanded, that is, polytetrafluoroethylene. The material is non-toxic, non-carcinogenic, non-allergic and other side effects, and has good biocompatibility and unique microporous structure. It can form a stable tissue connection with human body, and it is the most ideal biological tissue substitute at present. "However, the swollen body feels hard, which is its shortcoming."

Some beauty salons will use liquid injection for rhinoplasty. This method must not be done, because clinical observation has proved that liquid injection is easy to cause persistent erythema, swelling, skin necrosis and granuloma on the bridge of the nose, and the liquid substance can not be shaped, and it will flow and spread to the slack and depressed parts of facial tissue, which may make the nose very large and difficult to take out when there is a problem.
