Breast augmentation surgery is more traumatic in cosmetic surgery and may result in infection and significant bleeding after surgery, which in turn may cause contracture of the envelope and abnormalities in the shape of the implant. If you choose autologous fat breast augmentation, local fat liquefaction, necrosis, malabsorption and nodules may occur, and even infection may occur, requiring secondary repair surgery. For different cases, the surgical repair method will be different, and the surgical risk needs to be judged according to the specific situation: 1, after breast augmentation surgery, there may be a contracture of the envelope, if the contracture of the envelope has seriously affected the appearance, or caused strong discomfort, the envelope needs to be removed with an open incision, so that the breast can recover softness, and the doctor will re-peel the cavity of the implant to release the stimulation of the old implant to the tissue, completely The new implant will be inserted after removing the envelope, but there is still a possibility of recurrence and hardening in the future due to body differences; 2. When doing breast augmentation surgery, if the endoscope is not used to see the tissues in the body, it may lead to a less precise position after putting in the implant, which will form an overly stiff bowl-shaped breast or even a more irregular breast shape. If this problem occurs, it can only be repaired with an incision from the areola or the lower edge of the breast, but there may be a risk of visible scarring; 3. Since breast tissue is rich in blood supply, if during surgery, blood vessels are damaged, it may lead to increased bleeding; 4. Some candidates may also experience movement of the implant position or implant rupture or leakage after surgery. Therefore, it is recommended that candidates should choose a professional hospital and have this surgery performed by a professional doctor in order to reduce the risk of surgery.
