The hazards of silicone breast implant surgery mainly include the following aspects: 1, poor postoperative results: if the design of the silicone implant breast augmentation surgery program is unprofessional, it may lead to the implant position is too high or left-right asymmetric, and need to be adjusted and repaired again; 2, implant rupture and leakage: if the doctor is not properly operated or the external objects are seriously extruded, it may lead to the implant rupture or leakage, and need to be operated to take out the rupture of the implant immediately 3. Peritoneal contracture: Breasts may become hard after surgery, mainly due to peritoneal contracture, which may be related to the implant itself, implant implant position, surgical infection and hematoma. The contracture can be divided into four degrees, and when it develops into the third or even the fourth degree, only open surgery to remove the peritoneum can let the breast restore softness, but there is still a possibility of hardening in the future; 4. Postoperative hematoma: mostly caused by too rough or insufficient hemostasis. When repairing, it is necessary to suction the bruises in time; 5. Post-operative infection: if the prosthesis and instruments are not completely sterilized or the post-operative care is not proper, post-operative infection may occur. Once this happens, the prosthesis needs to be taken out in time.
