Grinding mandibular angle is a safe operation with no side effects, because grinding mandibular angle does not need to remove any bones. As long as the thickness of the mandibular angle is thinned with professional tools, the width can be reduced.
Patients are required to stay in hospital for 3-5 days after mandibular angle grinding, and the head mask should be bandaged with pressure for 5-7 days after mandibular angle grinding. If there are no special circumstances, it should be bandaged in time to check whether the skin is crushed. If a drainage strip is placed in an oral wound, it should be taken out 48 hours after operation. The swelling period lasts for one week, and it can completely return to nature after one month. It is recommended to eat liquid foods such as porridge, clear soup, fruit juice, milk or gravy all week.
