Hello, there are two kinds of materials for rhinoplasty, one is autologous tissue and the other is artificial plastic material. The materials for nose bridge plastic surgery are mostly silicone rubber and Gore-tex, and the materials for nose head plastic surgery are mostly cartilage and expanded polytetrafluoroethylene. The commonly used material is cartilage or dermal fat extracted from autologous tissue, namely ear or nasal septum. Silicone rubber has always been the most widely used artificial plastic material, but the frequency of using expanded polytetrafluoroethylene has increased recently.
