Abstract

Combining double-jaw surgery and orthodontic treatment to correct dentofacial asymmetry is a standard procedure but time consuming and costly. In order to provide alternative solutions, previewing the possible results with precise virtual surgical planning (VSP) system can help clinicians select patients suited for correcting facial asymmetry surgically without orthodontic treatment. In our experiences, after rigid or semirigid fixation of the maxilla, using intermaxillary fixation (IMF) without mandibular bony fixation is another key. This kind of fixation can minimize the chances of changing the condylar position and occlusion after the rotation of the maxillomandibular complex. If the original occlusion can be maintained, then orthodontic treatment can be avoided. Here we presented two facial asymmetry cases who requested surgical correction and refused orthodontic treatment. With careful preoperative planning using VSP, double-jaw surgery with maxillary bony fixation and IMF was conducted and both patients were satisfied by their aesthetic outcomes. With minimal dental compensation, the long-term results were relatively stable.
