摘要: Injury to the inferior alveolar nerve (IAN) during surgery is an important complication of bilateral sagittal split osteotomy. With cone beam computed tomography, course and its relationship surrounding structures can be assessed in three dimensions. This study aims determine whether tomography predict attachment neurovascular bundle proximal segment mandible osteotomy (SSO). Bilateral linear measurements were taken on cross-sectional images. During osteotomy, it was noted for each patient attached split. If attached, a bone-cutting instrument or blunt needed free nerve. The at more than one-third operation sites (170 sites). Of these, over 65% nerves (108 sites) required intervention them from mandible. After correcting confounding factors, distances buccal cortical margin IAN canal inner outer margins predictors will SSO.
