| Outline of Final Research Achievements |
This study aimed to evaluate the influence of maxillary impaction orthognathic surgery on nasal respiratory function and the efficacy of bone trimming at the inferior edge of the pyriform aperture. In the preoperative and postoperative models, there were significant correlations between the cross-sectional area and the pressure effort in each part of the nasal cavity. The postoperative pressure effort showed a tendency to decrease and the cross-sectional area showed a tendency to increase in each part of the nasal cavity. In four 2 mm stenosis models, the pressure effort in the anterior nasal cavity was larger than the preoperative pressure effort, and the cross-sectional area of the anterior nasal cavity was smaller than the preoperative cross-sectional area. Bone trimming at the inferior edge of the pyriform aperture appears to be useful for avoiding nasal respiratory complications with maxillary impaction.
