Ground covering surgery is a method to treat malocclusion, which mainly includes sagittal split osteotomy of mandibular ramus and vertical or inclined osteotomy of mandibular ramus. Although the risk of operation in the field is not particularly great, any operation has certain risks, especially the operation of incision and eating in the mouth may increase the risk of infection.
Some patients have surgery in other places, and there is generally no risk in regular medical institutions, but postoperative infection may occur, and may be accompanied by sequelae such as local nerve tissue damage.
