Breast augmentation surgery usually refers to breast implant surgery, which is generally safe under standardized operation, but it may also cause mammary gland destruction, periosteal contracture, surgical bleeding and wound infection. 1. Breast destruction: If the implant leaks and ruptures, it will lead to breast destruction. 2. Periosteal contracture: When the implant is implanted into the breast, the periosteum will gradually become thicker and the space around the implant will become narrower, and when the periosteum is tightened, the hardened implant will also be deformed. 3. Surgical bleeding and wound infection: If the operator does not operate properly during the operation or take care of the wound properly after the operation, it may cause surgical bleeding or wound infection. For patients who need breast augmentation surgery, it is recommended to go to regular hospitals and have breast augmentation surgery under the operation of professional doctors.
