Mandibular angle plastic surgery is to achieve the effect of face-lifting by removing part of the mandible and changing the position of the bone. The operation will take 2-3 hours. The operation is carried out under general anesthesia, so there will be no pain during the operation, but the beauty seeker will feel pain after the operation. However, these pains will not be too severe. After mandibular surgery, you need to stay in hospital for 2-3 days, which can not only facilitate the doctor's postoperative observation, but also do a good job of postoperative care in the early stage.
