[Computed tomography investigation of temporomandibular joint in surgery of dento-maxillary anomalies].
The aim of this study was to evaluate changes in the temporomandibular joint morphology, regarding the relation between mandibular condyle and fossa, after bilateral sagittal split osteotomy in Angle class III dentomaxillary anomalies. Preserving the preoperative position of the condyle during sagittal split osteotomy is considered important to obtain skeletal and occlusal stability. Cone-beam computed tomography of 20 class III patients with mandibular prognathism were assessed before and 6 weeks after operation to evaluate changes of the condylar position. We propose a protocol for head posture and computed tomography investigation, which makes possible the comparison between cone-beam computed tomography (CBCT) in different moments at the same patient. There are no significant changes after bilateral sagittal split osteotomy regarding joint relations.
