First, for the malocclusion caused by maxillary retraction, it is necessary to move the maxilla forward by osteotomy, that is, to correct the malocclusion by moving the maxilla forward as a whole through special osteotomy. At the same time, the depression in the middle part of the face was also improved obviously after the maxillary moved forward. After malocclusion correction, if the nose of individual patients is low, rhinoplasty can further increase the three-dimensional sense of the face.

Second, for the malocclusion caused by mandibular protrusion, the operation is mainly aimed at the mandible. After special osteotomy, the mandible will retreat as a whole to correct mandibular protrusion, thus achieving the purpose of correcting malocclusion. By cutting the mandible back, not only the length of the mandible is shortened, but also the maxilla rotates upward when it retreats, the angle of the mandibular angle becomes smaller and the side view becomes more beautiful. If the chin is too long, the jaw osteotomy should be shortened at the same time.

Thirdly, patients with malocclusion with maxillary retraction and mandibular protrusion need to undergo maxillary osteotomy and mandibular osteotomy at the same time, and mental osteotomy and plastic surgery if necessary.

You'd better go to the hospital for a check-up if you have time ~ ~
