Breast augmentation surgery is divided into breast implant and autologous fat transplantation. The specific hazards and after-effects of different types of breast augmentation surgery will be different, so it is impossible to generalize the hazards and after-effects of breast augmentation surgery. 1. Breast implant: after breast implant surgery, there may be rejection reaction of the implant, asymmetry of the two breasts after surgery, hardness of the two breasts like stone after surgery, etc. There may also be the appearance of the implant, the feeling of the implant does not meet the requirements of the aesthetes. 2. Autologous fat transplantation: the defect of autologous fat breast augmentation is that the absorption rate is relatively high, and the absorption rate after operation may be 30%~60% or 70%~80%. And when doing autologous fat transplantation surgery, if the doctor is not operating properly, there may be a relatively low survival rate after transplantation. It is important to pay attention to daily care after breast augmentation surgery to minimize the occurrence of postoperative complications.
