Artificial rhinoplasty prosthesis material is currently the most used rhinoplasty implant material, mainly including silicone and bentonite two. Silicone gel prosthesis: from the historical experience, silicone gel prosthesis is safe, low rejection rate, cheap and practical material, good surgical effect and can be maintained permanently; in case of infection, deviation, penetration and other special circumstances can be completely removed from the prosthesis, and then repaired again or replaced with other types of prosthesis. Therefore, silicone prosthesis has become the first choice of artificial polymer synthetic material, do not reject it because it is cheap or everyone uses it. However, for those who have thin skin on the nose, those who have particularly tight skin and a particularly low nose, or those who want a particularly high nose bridge and a particularly pointed tip, silicone implants alone cannot fulfill the requirements. Expanded material: Expanded material has a lot of micropores, which can be tightly combined with your own tissue cells and is impervious to light, allowing you to pad the bridge of your nose very high. However, it is risky to pad the tip of the nose with bentonite alone. Because the bentonite in vivo hardness is relatively large, strong tension, the abrasion force on the skin is large, easy to top the skin, often need to be added to the surface of the autologous tissue such as cartilage as a shield to protect. Expanded body is expensive, the risk of infection and rejection is relatively high; once these conditions occur in the removal of the nose is also very large damage, for the later repair caused great difficulties. The choice of these materials should be based on the advice of a professional doctor, and the most suitable for you on the basis of safety and suitability.
