Commonly used materials for rhinoplasty are: silicone, ivory, artificial bone materials and expanded PTFE and human bone or cartilage, etc. 1, silicone: it is a class of organic compounds, from which medical-grade silicone rubber is prepared, easy to operate, the effect is ideal, and there are few complications. It can be cut and sculpted at will according to the needs of the patient. It is also easy to remove in case of unsatisfactory results. It is currently the most commonly used material for rhinoplasty. Structure is also divided into the whole and a, two-segment, three-segment and several other. 2. Expanded polytetrafluoroethylene (ePTFE): from the medical point of view, is currently the most ideal biological tissue substitute. Due to its good biocompatibility and unique microporous structure, non-toxic, non-cancerous, non-allergenic and other side effects, and human tissue cells and blood vessels can grow into its microporous, forming tissue connections, as in the case of autologous tissue. 3. Autologous bone or cartilage: it is one of the early materials used in rhinoplasty, the advantage of which is that it is easy to survive after transplantation and rejection will never occur. The disadvantage is that it is difficult to take the material, causing secondary pain to the patient, and there are also problems such as difficulty in sculpting.
