Breast augmentation is also commonly known as breast augmentation. At present, the most popular surgical methods are breast augmentation with prosthesis and breast augmentation with autologous fat transplantation. Prosthetic breast augmentation is performed under general anesthesia. Breast prosthesis is placed in the chest to make the chest firm and full, so as to achieve the purpose of breast enhancement. Prosthetic breast augmentation can obtain satisfactory convexity and fullness. Fat breast augmentation is a surgical method to extract autologous fat under general anesthesia or intravenous anesthesia and transplant it to the chest after treatment to make the chest plump. The transplanted fat has a certain absorption rate. For the first time, the absorption rate of fat is about 30%-70%. The second breast augmentation, the fat absorption rate is lower than the first one, because the first fat transplantation has laid a good foundation. Generally, according to the patient's chest foundation, autologous fat breast augmentation is needed for 2-4 times. Fat breast augmentation feels good, plump and protruding. However, some patients are prone to fatty nodules after operation, and small nodules are not easy to become malignant. If nodules appear, they can be removed by suction.
