Breast augmentation has long been the first choice for many women to increase their self-confidence and rebuild their confidence. Breast augmentation surgery has a long history of being safe, fast, effective and non-toxic as the first choice for breast augmentation. However, breast augmentation surgery has caused many patients to have concerns: contracture of the envelope, poor handfeel, large scars, broken implants, need for replacement and removal due to aging, etc. The emergence of autologous fat breast augmentation is a good solution to the above problems, because the fat is taken from oneself, there is no rejection, good feel, natural, and can exist permanently, no scars, etc., it has been rapidly spread. Another feature is that it can extract excess fat from the abdomen and thighs at the same time as breast augmentation to achieve a good body shaping effect, and the price is similar to that of breast implants, so the cost performance ratio is significantly improved. It is especially suitable for patients with fat accumulation in the waist and abdomen after childbirth, sagging breasts and young patients with poorly developed breasts and unsatisfactory body shape. The main complications of autologous fat transfer breast augmentation surgery are postoperative hematoma, fat embolism, infection, hard nodes and low fat viability, etc. The gentle operation, strict aseptic operation and meticulous treatment of the extracted fat tissue are effective ways to avoid these complications.
