Suggestion: Hello. At present, the most commonly used implants in rhinoplasty are augmentation mammoplasty and silicone prosthesis. Different personal needs make different choices. There are also some differences in the prices of expanded and silicone rhinoplasty materials, so how to ensure the effect of rhinoplasty materials? Let's look at the difference between breast augmentation and silicone rhinoplasty. Firstly, the histocompatibility of the two materials was compared. Expansive materials and silicone prostheses have good high and low temperature resistance, good chemical stability, corrosion resistance and histocompatibility, and are non-toxic, non-carcinogenic and non-teratogenic, but a few people will reject them. Due to the special structure of the expansion material, blood vessels and nerves can gradually grow into the expansion body, so that the expansion body can grow together with human tissue, while the silicone prosthesis can not grow together with human tissue. After implantation, there may be a slight one-off inflammatory reaction in the local area, and a thin fibrous capsule will be formed around it in the later stage, which is the most widely used and effective material for rhinoplasty. Secondly, compare the plasticity of the two methods. Although the expanded material has certain flexibility, its elasticity and three-dimensional effect are poor, so it is not suitable for carving and shaping, and the effect of supporting the nose column and tip is not good. The silicone prosthesis itself has the basic shape of the nose and can be carved at will. Silicone rubber can be prefabricated into various shapes and models of nasal prosthesis, such as nose tip, nose wing, nose column and so on. , commonly used are "L" shape, "T" shape and willow shape. Good flexibility and elasticity, strong three-dimensional sense. Thirdly, through the observation of some patients, we found that when the organic tissue grows in, the expanded material will lose its original elasticity and become very solid, which will make its appearance and feel unreal and make the nose look dull and unnatural. But silicone prostheses don't have this problem. It will not change its corresponding shape with the passage of time, tissue growth will not occur, and it will not change its feel. Toughness and elasticity are relatively stable, so it is natural. Fourthly, because the expanded material has the characteristics of tissue growth, it brings trouble to the patient's second operation. Through observation, we found that the longer the swelling stays in the body, the more unfavorable it is to take it out. Due to the growth and swelling of tissues, the cavity formed is getting smaller and smaller, so if the swollen substance is taken out, it is like taking out a piece of your own tissue, which is self-evident.
