With the development of science and technology, a variety of rhinoplasty materials have been developed. At present, there are three kinds of materials widely used, namely silicone rhinoplasty, rhinoplasty and autologous cartilage rhinoplasty. Different rhinoplasty materials have their own advantages and disadvantages. Artificial bone materials mainly refer to hydroxyapatite. It is the main inorganic component of human bone tissue, so it has good biocompatibility, no toxicity, no teratogenic, sensitizing and carcinogenic side effects. Easy to operate and shape, especially for patients with low nose, and the postoperative effect is particularly satisfactory. Because there is no supporting effect, it has poor effect on people with low nasal tip. From the medical point of view, swelling body is the most ideal substitute for biological tissue at present. Because of its good biocompatibility and unique microporous structure, it is non-toxic. Without side effects such as carcinogenesis and sensitization, human tissue cells and blood vessels can grow into their micropores to form tissue connections, just like autologous tissue. The effect of rhinoplasty with it is satisfactory. For details, the landlord can go to Changsha for a doctor's face examination and choose the one that suits him. I hope it helps you.
