The so-called prosthesis-filled breast augmentation is a surgical method to support the breast with artificial prosthesis. Prosthetic breast augmentation has immediate effect, but it is very risky. The human body's own protective function will produce rejection reaction to foreign substances. Therefore, when the prosthesis is placed in the body, a film will be formed around it to completely wrap the prosthesis. On the one hand, this membrane protects the tissue around the breast, on the other hand, it can also prevent the prosthesis from shifting. The rejection of some surgeons is particularly obvious. If the capsule is thick, it will gradually harden and the prosthesis must be replaced again. Autologous fat transplantation is similar to injection breast augmentation surgery. Fat cells are extracted from other parts of the human body and injected into the breast to achieve the effect of breast enhancement. There is no doubt that the toxicity of transplanted fat to human body is zero, so it has once become a favorite breast augmentation method for many surgeons, but it has a fatal disadvantage: the transplanted fat cannot survive 100%, and the larger the transplanted volume, the lower the survival probability. After fat is transplanted from other parts of the human body to the breast, there must be enough supply to slowly combine with the surrounding tissue environment. The bigger the transplant volume, the more supplies are needed. Once the supply is insufficient, some fat cells will shrink and die. According to the individual's physical condition, the viability of fat will be different. Generally speaking, only about 50% can survive after transplantation of 100 ml fat. If it exceeds 200 ml, the survival rate usually does not exceed 40%. Usually you can't inject too much at a time. But now with the help of BRAVA breast enhancement medical equipment, it can expand the space for fat, help the chest absorb fat and improve the survival rate of fat. It has been successfully applied to breast reconstruction of breast cancer patients. BRAVA can also be used alone. It is a second-class breast enhancement medical device from the United States. According to the principle of tissue expansion, it is natural and safe to induce breast self-development through external force. BRAVA has been introduced into some authoritative hospitals in China, such as Peking Union Medical College Hospital and China Plastic Surgery Hospital. It has been proved that it can improve breast enhancement, one big and one small, sagging and so on. After follow-up, the incidence of breast cancer in 65438+ 10,000 women who used BRVA was much lower than that in women who did not use BRVA.
