For two weeks after surgery (especially when sleeping) the upper extremity is abducted 90 degrees to allow the axillary wound to dry. Gradually raise the upper extremity 5 days after surgery and overhead for one week to prevent fascial contracture. The stitches are removed at one week. If the position of the prosthesis is too high or too low, or if there is obvious asymmetry between the two sides, it needs to be adjusted by the physician in time within one week. Hairy surface prosthesis, post-operative massage is not necessary and needs to be determined on a case-by-case basis. Swelling after surgery, it will be larger, and the size is basically set after a month. Feel soft need six months, some even need more than a year. And not all of them can be fake. It is normal that some of them can feel the edge of the prosthesis or implant. The incidence of contracture is about 3%, with varying degrees of severity, which means that it feels hard to the touch and requires reoperation if it is unacceptable. The prosthesis is a silicone capsule, the possibility of aging and leakage will gradually increase after 10-15 years, and will need to be checked or replaced every year.
