Is it better to use prosthesis for breast enhancement or autologous fat? This is the most frequently asked question in clinic. In fact, these two methods are considered to be safe breast augmentation methods from the perspective of medical safety, and they are also the most commonly used breast augmentation methods in surgery. However, these two methods have their own advantages and disadvantages. From the perspective of surgical methods, prosthesis is safer and more advantageous. The advantages of the prosthesis are good safety and good appearance, because the prosthesis is made by simulating the most beautiful breast shape, and its shape is sometimes beyond the normal development of the chest, so the shape after operation is more perfect. In addition, from the safety point of view, the prosthesis is complete, and silica gel is a very safe tissue material. If there is any problem, 100% can take out the prosthesis, so it is reversible and the operation is safe. However, one of the main problems of prosthesis is that the hand feel may not be particularly good, which depends on the individual's physique. Some people can really achieve a very good first-class feel, which is very soft, but some people may be slightly harder than normal tissues. The biggest advantage of autologous fat lies in its natural shape and feel, because breast tissue and fat feel soft, but its problem is that a fat is soft, it can't produce good convexity, it won't produce a particularly perfect shape, it can indeed achieve the effect of breast augmentation, but its shape is not perfect. Another part of the fat is absorbed, so it takes two to three or even more operations to achieve the ideal breast shape and volume. Its main problem lies in the induration of autologous fat, which can't be overcome and is brought by the operation itself. After autologous fat transplantation, almost 100% people will have induration. Although it is not a disease, it will not affect their health, but it must be found when doing B-ultrasound. Therefore, we should carefully consider the choice of surgery and communicate with doctors to choose the appropriate surgical method.
