Prosthetic rhinoplasty materials mainly include silica gel and swelling materials. Prosthesis rhinoplasty generally adopts molded silicone prosthesis, which is simple to shape and cheap. However, when the silicone is hard, the implant material is too large and the skin is thin, the appearance will be obvious, which is not suitable for patients with severe rhinoplasty. Expanded material, also known as PTFE, is a synthetic material with good tissue compatibility and natural appearance, which is suitable for patients with various degrees of nasal abnormalities, but it is difficult to shape and complicated to operate.
