Rhinoplasty is a type of rhinoplasty for people with low nasal bridge and unattractive nasal shape through artificial materials. The prosthesis is implanted as a support to increase the dorsal convexity of the nose and improve the shape of the nose. Commonly used implants include silicone gel, tumescent, etc. Candidates need to choose the appropriate implant material according to their own nasal shape conditions. The maintenance time of rhinoplasty is related to the material of the prosthesis. Silicone is one of the most commonly used prosthetic rhinoplasty materials, silicone prosthesis will increase with time aging, including contracture of the envelope and long-term complications, so the retention time will be relatively short, generally in about 10-20 years. Tumescent, also known as polytetrafluoroethylene, is also one of the rhinoplasty materials, which is a soft and microporous grafting material with a texture and feel very close to normal nasal tissue, which can be fused with autologous tissue and can exist for life without complications. Usually the implant material chosen for rhinoplasty is approved by the state and has a relatively long maintenance time when implanted in the nose. Some of these implants can last a lifetime if there is no rejection, infection or trauma or gravity.
