According to Li, an expert in plastic surgery at Huayi, silicone rubber has two characteristics, namely "hydrophobicity" and "fat solubility". After silicone rubber was implanted in human body for 2-3 months, the hydrophobicity completely disappeared and the fat-soluble effect was enhanced. The surface of silicone rubber prosthesis begins to be colored, and the colored part is softer than the uncolored part. With the passage of time, the pigment gradually deepened and turned yellow, and penetrated deeply. This phenomenon is the result of fat solubility, which is completely different from the situation of aging and hardening.
Some people may want to know how many years the silica gel in the prosthesis will age and harden. At present, most of the rhinoplasty materials used in China are solid silica gel, which is an inert substance with stable chemical properties. After more than ten years of clinical application and observation, it is proved that as long as the quality is guaranteed, it has no toxicity and pathogenicity, and there are few postoperative rejection. At the same time, it also has the following advantages: the operation is relatively simple, with the appearance of the molded nose model, it is more convenient to shape and can be completely taken out, and the treatment of postoperative complications and unsatisfactory appearance is relatively simple and convenient.
Li Huayi plastic surgery experts believe that if the life of one prosthesis reaches 30 years, it can be replaced by another prosthesis. This method is simple and harmless, and patients need not worry too much.
An important factor that silicone rubber for rhinoplasty will not deform after being implanted into human body is the non-adhesion between silicone rubber and tissue, which means that silicone rubber and human tissue will never grow into one. Within 1-2 weeks after operation, a thin fibrous tissue membrane will be formed around the implanted silicone rubber, which will tightly wrap the prosthesis. After about one month, the silicone rubber prosthesis will be firmly fixed and will not move even if it is hit. However, a prosthesis is an implant after all. Under normal circumstances, there is a gap of 100-200 a between the tissue capsule and the prosthesis, and the gap is filled with interstitial fluid, which has a protective effect on the tissue. However, when it is hit by repeated strong external forces, the gap may become larger and even produce inflammation and suppuration, so it is generally not recommended for some people who are vulnerable to trauma, such as boxers. If ordinary patients can't have a strong lump in their nose within two weeks after operation, the expected effect of the operation can be achieved. Will the wrong experience change after rhinoplasty is old? There's no need to worry.
