Material Classification There are three main ① Silicone prosthesis: domestic and Korean imports, is a commonly used material in the plastic surgery industry, its biocompatibility is good, stable, easy to shape, non-toxic, non-teratogenic, rhinoplasty effect is very ideal, but also plastic surgery institutions in various countries rhinoplasty preferred material, the price is more appropriate, easy to take and put, a molding. Silicone prosthesis silicone prosthesis ② PTFE: is a porous solid material, it has many micropores, the nature of its stability, soft texture and easy to carve the shape, the shape is realistic, low incidence of rejection. Expanded material Expanded material ③ Autologous cartilage: it has the characteristic of non-rejection of autologous tissue, this method of rhinoplasty is suitable for the overall shaping of the nose and specialized tip shaping, it is compatible with the cartilage at the tip of the nose in the best way and the most lifelike.
