1, silica gel: It is an organic compound, and medical grade silicone rubber is prepared from it. The operation is simple, the effect is ideal and the complications are few. Can be arbitrarily cut and carved according to the needs of the subject. In case it is not ideal, it is easy to take it out. It is the most commonly used rhinoplasty material at present. The structure is divided into whole and one, two and three.

2. Expanded PTFE: From a medical point of view, it is the most ideal biological tissue substitute at present. Because of its good biocompatibility and unique microporous structure, it is non-toxic, non-carcinogenic and non-allergenic. Human tissue cells and blood vessels can grow into its micropores to form tissue connections, just like autologous tissue.

3. Autologous bone or cartilage: it is one of the materials used for rhinoplasty earlier. Its advantage is that it is easy to survive after transplantation and will never be rejected. The disadvantage is that it is difficult to obtain materials, causing secondary pain to the subject, and it is also difficult to carve.

At present, rhinoplasty materials can be roughly divided into two categories, self-organized and synthetic materials. Autologous tissue includes autologous bone tissue, autologous cartilage tissue and autologous soft tissue. At present, autologous tissue (especially simple rhinoplasty) is rarely used in clinic, because the use of autologous tissue needs to add another wound and scar, which increases the risk, and patients are generally unwilling. Synthetic materials are relatively safe. At present, there are two kinds of materials widely used in clinic: expanded polytetrafluoroethylene and solid silica gel, which can be preserved for life. A large amount of evidence proves that it can be completely removed once it is needed after implantation.

★★★★★ Plastic consultant Yao★★★★ Tip: Any operation has certain risks. The best way to avoid risks is to choose a regular plastic surgery hospital and a responsible professional plastic surgeon before operation, and make good preparations before and after operation, so as to ensure the safety of the operation and the effect of the operation is foolproof.

I have written about how to choose a good plastic surgery hospital and plastic surgeon (please refer to Beijing Plastic Surgery Blog). You can refer to the principles inside to choose two or three doctors you trust, consult face to face, and choose a good doctor that suits you best.
