Silica gel and swelling are commonly used materials for prosthetic rhinoplasty, and we can't say which is better, and each has its own advantages and disadvantages. Silicone can be divided into medical silicone and liquid silicone. Liquid silica gel is no longer used, because it is injection rhinoplasty, which is not safe. At present, medical silica gel is mainly used. Medical silica gel is a safe and effective implant material. Laboratory and clinical experiments show that it is compatible with human tissues, non-toxic and harmless, and has strong plasticity. Advantages: good elasticity, soft feel, easy shaping, good chemical inertia, non-toxic, non-carcinogenic, non-teratogenic, and relatively stable histocompatibility. And the shape is basically shaped, and it can be used with a little modification according to everyone's situation; The color is similar to the skin, and there will be no false feeling; Third, it is easy to plug in and out. Disadvantages: after implantation in the body, there may be a mild one-off inflammatory reaction in the local area; If the tip of the nose is plastic, excessive tension may turn red; If the silicone rubber prosthesis is placed on the tip of the nose, if the tip is too high, it will be too hard to raise the tip of the nose; A few people have allergic reactions to silicone rubber, that is, rejection. At this time, the prosthesis should be removed in time, or implants made of other materials should be replaced. Rhinoplasty is to make a plan according to the patient's requirements and facial conditions. The carefully carved augmentation mammoplasty was implanted under the nasal periosteum and fixed internally to recombine the alar cartilage and subcutaneous tissue. It is a widely used rhinoplasty method in recent years. From the medical point of view, swelling material is the most ideal substitute for biological tissue at present. Advantages of detumescence: the detumescence can be basically reduced one month after operation, and the effect is obvious in 3-6 months, and it will not cause nasal congestion, olfactory change, sinusitis, rhinitis and other problems. It is softer than silicone rubber and more natural after operation, especially suitable for patients with thin nasal skin. Disadvantages: the price is high, but this kind of rhinoplasty must strictly disinfect the prosthesis, otherwise it will easily affect the surgical effect. Anesthesia is usually performed during rhinoplasty, which is risky.
