First, after mandibular angle plastic surgery, the face will be swollen. This is mainly because the bones will be injured during the operation, and the skin tissue will be damaged to a certain extent, so it will swell. But generally don't worry, the swelling will generally decrease in about 7 days.

Second, after the operation, if you touch the surgical site in a short time, there will be tenderness. This is because there will be a small amount of bleeding after the operation, which will usually disappear in a week or so.

Third, for a period of time, it will be difficult to open a wide range of mouths. This is because the muscles and other tissues need to be peeled off during the operation, and there will be slight damage. It will be normal in about three months, so don't worry. Because there will be little bleeding during the operation, the external skin corresponding to the incision may appear bluish purple, which can be eliminated in about 1 week.
