It is best to stay in hospital for 2-3 days after mandibular angle plastic surgery, during which it is best to squeeze and bandage the wound for about a week, which can effectively prevent postoperative discomfort and swelling. Don't massage your face for three months after operation, and try to avoid touching the surgical site. It is best to eat some liquid food within a week, and avoid some spicy food and biting hard food within three months.

To solve the problem of postoperative swelling, there will be different degrees of swelling on the face after operation, which will gradually subside in about 3-7 days. If the condition improves about a week after the resection of mandibular angle hypertrophy, the suture can be removed. It takes about 1 month for the operation to completely reduce swelling. The masseter muscle itself will rebuild itself and shrink due to the change of attachment position and muscle tension in about 3-6 months, so the recovery will achieve the best effect in about 6 months after operation.
