& ltp> mandibular angle osteotomy is an arc osteotomy that uses a small saw to remove the protruding part of the mandibular angle and mandibular angle margin, which can completely remove the inner and outer plates of the mandible, mainly in the "mandibular angle-mandibular angle margin" area, that is, the removed part will be completely pulled away and no longer exist. & lt/p & gt； & ltp> Because of the direct resection of the hypertrophy, the mandibular angle spacing is obviously reduced after operation, and the curvature of the chin is also very harmonious, and the effect is natural and beautiful. & lt/p & gt； & ltp> Under normal circumstances, it is normal to have difficulty opening your mouth within one week after mandibular angle surgery, and it will disappear after recovery. & lt/p & gt； & LTP> & ltimg src = \ "/uploadfile/image/20191206/157519068656733.jpg \" alt = \ "Chen Yuan Plastic Surgery. & ltp> However, it should be noted that mandibular angle surgery is a four-level operation, so it needs strict examination in hospital health and safety, doctor qualification and operation. If you choose institutions rashly, it is likely to produce a series of sequelae, from unsatisfactory postoperative results to insignificant results, to bilateral asymmetry, fractures, massive bleeding, infection, nerve damage, excessive interception and other situations that are difficult to repair. & lt/p & gt； & LTP> & ltimg src = \ "/uploadfile/image/20191206/157519068405835.jpg \" alt = \ "Korea fezreh. & ltp> Like nerve injury, you should know that there are many very important tissue structures in the human maxillofacial region. If the position of nerve is not determined before operation, it may cut off the inferior alveolar nerve of the patient, leading to involuntary drooling, lower lip occlusion, facial paralysis, etc., which makes people regret it. & lt/p & gt； & ltp> Another example is the loss of mandibular angle caused by excessive interception. This situation often happens when doctors are inexperienced in technology, can't master the radian of osteotomy well during operation, or blindly pursue the effect of face-lifting, resulting in the loss of mandible, which is difficult to repair or beyond repair. & lt/p & gt；
