1: Expanded Polytetrafluoroethylene (EPPTFE)-made in America, which is the best rhinoplasty material in the world at present; The nose shape after operation is natural and realistic; However, the materials are expensive and the requirements for surgeons are high.
2. Solid silicone nose prosthesis-commonly used by cosmetic plastic surgeons.
Rhinoplasty materials; It was used as early as 1972. After more than 20 years of observation, although the incidence of complications can reach 5%-20%, it is still one of the first choice materials for rhinoplasty because of its good biocompatibility, chemical inertia, non-toxicity, non-carcinogenicity and low price. Solid silicone nose prosthesis is a kind of solid polymer vulcanized at high temperature, which has certain elasticity and hardness. There are L-shaped and willow-shaped solid silicone prostheses, which are simple to operate and relatively cheap. The silicone materials used for rhinoplasty in plastic surgery hospitals are personalized prostheses carved by doctors according to the patient's nose shape, and the postoperative appearance is natural and realistic.
3. hyaluronic acid-hyaluronic acid, also known as hyaluronic acid, is an indispensable component in the skin tissue structure of organisms. As a part of body tissue, it has good histocompatibility. Hyaluronic acid injection rhinoplasty has the limitation of being absorbed by human body, but it has the advantages of no operation, quick response, high safety and moisturizing function, which can increase elasticity and lubricity and keep skin soft. The nose shaped by hyaluronic acid is natural and straight, and there will be no stiff feeling.
4. Artificial bone materials-mainly hydroxyapatite. It is the main inorganic component of human bone tissue, so it has good biocompatibility and no side effects such as teratogenesis, sensitization and carcinogenesis.
