Autologous fat breast augmentation is a very good surgical method because the fat source is autologous and it is the safest way of breast augmentation. Liposuction in the abdomen and thighs can be used for body sculpting, and the body shape can be significantly changed, the fat source is abundant, there is no periosteal contracture that occurs with prosthetic materials, there is no surgical incision, there are so many advantages, so now this surgery is also gradually becoming popular and has the potential to replace breast augmentation with prosthesis. After fat transplantation, some of the fat will not survive, the survival rate is about 30-70%, which varies from person to person, and it is also related to the method of taking fat tissue, the treatment method, the method of selecting active fat tissue, the injection method, the doctor’s experience and many other factors. Therefore, it is quite important to find a regular hospital and an experienced doctor. The improvement of the method of injection in my experience is the most important, and the most crucial is to inject the transplanted fat tissue more evenly to the recipient area, and the key to the fact that currently more than 200ml of fat can be injected into each side of the breast without problems. So what does the transplanted fat end up being if it does not survive well? Part of it is absorbed, which is fine and can be replenished next time. There is also the formation of fibrosis and calcification, which means that there are bumps and cysts, and this is the biggest problem, but it does not contribute to the development of breast cancer. This is the biggest problem, but it does not contribute to the development of breast cancer. This is closely related to the operation method of the doctor. One of the most popular methods to increase the viability of fat is to add stem cells to the fat during fat transfer. Stem cells have fat-derived stem cells, which means that twice as much fat is sucked out when liposuction is needed, half of which is used to divide the stem cells and half of which is used for fat grafting. This treatment is currently available in China, but there is controversy in academia, some believe that there is no significant effect when fat stem cells are added. Now I am doing a method that does not need to separate the stem cells and then add them, and through the simplest centrifugation that can get the best fat tissue with high concentration of stem cells, because centrifugation is also a process of selecting fat, after centrifugation (certain centrifugal force and time) the fat will be stratified, the upper layer of fat is bad, poor activity, stem cells or precursor cells which are strong because of small size and high density, basically in the lower layer. density, basically in the lower layer, so try to choose the lower layer is also selected to use the part of high concentration of stem cells, the effect is stronger. One kind of stem cells is the stem cells from your own bone marrow, which can be easily separated and in sufficient quantity, without incision and without pain in anesthesia. Another method is PRF, which is an upgrade of PRP, and it is more effective than it. It can release a large amount of growth factors to ensure the survival of fat and the quality of survival. The latest development is to use BRAVA combined with fat grafting, which can improve the blood flow to the recipient area and increase the volume of the recipient area, and the results can be significantly improved.
