Posterior Pharyngeal Airway in Clockwise Rotation of Maxillomandibular Complex Using Surgery-first Orthognathic Approach

摘要: The treatment of patients with prognathism requires combined orthodontic and surgical procedures the aim to achieve normal occlusion an improved aesthetic facial profile. In traditional for orthognathic surgery, anterior-posterior discrepancies are corrected by advancement or setback jaw along existing occlusal plane.1–3 This procedure, however, often fails move maxilla mandible onto ideal positions does not produce optimal result in terms aesthetics, especially Asians who have a preexisting dentoalveolar protrusion. Therefore, alternative designs should be considered such cases. Reyneke et al4 suggested that alteration plane could alternative. A change based on rotation maxillomandibular complex (MMC) better solution overcome limits simple plane. We previously presented effect surgery clockwise MMC using 3-dimensional photogrammetric analysis.5 In our practice, is recently common procedure surgery-first approach because this can correct dental compensation anterior teeth minimal presurgical treatment. addition, many Asian class III prognathic protrusion, much when maxillary mandibular would appropriate. Furthermore, kind very useful way which without overcomes minimizes instability immediately follows surgery. Many recent reports revealed us turned out quite reliable satisfactory correction if it done proper indications preoperative evaluation.6–9 Meanwhile, posterior pharyngeal airway space after dentofacial deformities has been investigated intensively.10–19 However, rotational movement undergone investigated. There also only few regarding MMC, but airway. Because any 2-jaw cause snoring obstructive sleep apnea, we as first step.
