The risks and hazards of breast augmentation surgery are generally periosteum contracture, implant displacement, infection, implant rupture and so on. 1. Periosteal contracture: after implanting the implant in breast augmentation surgery, a kind of periosteum will be formed outside the implant, and if the periosteum is thicker, the internal fiber tissue will contract and form periosteal contracture, which will make the stretching of the implant be affected, and it looks like the form is more fake, and due to the fact that there is a periosteum wrapped around the outside, the feeling of the hand is also more hard, so it is prone to risks and hazards of the form and the feeling of the hand. 2. Displacement of the prosthesis: the prosthesis may be displaced due to surgical errors, improper placement of the prosthesis, or lack of effective postoperative care. 3. Infection: If there is no effective care after breast augmentation surgery, it will lead to chest infection, which is usually accompanied by symptoms such as swelling, hardness, redness, pain, warmth, and difference in the size of the chest. 4. Implant rupture: Implant rupture often occurs several years after implantation of the implant, due to the aging of the implant, so we recommend that candidates choose a regular medical institutions, regular medical institutions have better medical equipment and team of doctors, can reduce the emergence of harm.
