Autologous fat cell transplantation for breast augmentation, which is a higher-end and more advanced method of breast augmentation surgery at present, mainly involves extracting fat tissues from certain parts of the breast augmenter’s own body, such as abdomen, buttocks, thighs, etc., and then injecting them into the breast augmenter’s breasts after purification treatment to achieve the effect of breast augmentation. The surgical procedure mainly includes: firstly, use 2-3mm minimally invasive liposuction needle to suck out the fat mixture from the waist, legs, buttocks and other places where there is more sufficient fat, and then get the pure fat particles after purification treatment. Secondly, after calculating the injection volume on the left and right sides of the breasts, the pure fat particles are transplanted to the deep surface of the breast glands and the surface of the pectoralis major muscle, and localized massaging makes the fat distribution even, so that the volume of the breasts is increased to achieve the ideal contouring. However, it should be noted that due to the limited capacity of the tissue behind the breast, too much fat tissue cannot be injected at one time, otherwise the transplanted fat tissue cannot get sufficient blood supply and is prone to necrosis. In addition, there will be a certain absorption rate in the extracted fat, so autologous fat breast augmentation usually requires more than 3 times to have more obvious results, and each time needs an interval of 1-2 months.
