Mandibular asymmetry cannot be corrected by self-correction, but can be treated by orthognathic surgery or combined orthognathic and orthodontic surgery under the guidance of a doctor. 1. Orthognathic Surgery: Asymmetry of the mandible may be due to abnormalities in the length, width and height of the bones on both sides, so patients usually need to undergo orthognathic surgery after diagnosis by a doctor in order to make both sides of the bones symmetrical in shape. 2. Orthognathic surgery: Jaw asymmetry may also be caused by dental factors such as abnormal development of jaws or malformation of teeth, if only orthognathic surgery can not achieve the therapeutic effect, the patient needs to wear braces for orthodontic treatment before orthognathic surgery to achieve curative effect. It is recommended that patients go to the hospital in time for examination and treatment under the guidance of the doctor.
