3D analysis of condylar position after sagittal split osteotomy of the mandible in mono- and bimaxillary orthognathic surgery - a methodology study in 18 patients.

摘要: This study analyzes the condylar position with intercondylar distance and angle after sagittal split osteotomy in mono- bimaxillary orthognathic surgery applying cone-beam computed tomography (CBCT) images before surgery. Data of 18 patients, ten males (mean age 28 years) eight females (mean age 26 undergoing the described between 2008 2009 were analyzed. CBCT scans performed KaVo 3DeXam (KaVo, Biberach/ Ris, Germany) (identical iCAT scan device) before and The exported DICOM data analyzed with ImageJ morphometry software. Patients also asked about TMJ problems. two-tailed t test was used significance was set at a p value less than = 0.05. There no significant difference pre- and postoperative distances centers (mean difference: 1 mm) (p 0.69) intercondylar difference: 6.6°) 0.27). CBCT is novel imaging technique appropriate for detailed three-dimensional analysis position in Available freeware software can be applied for metrical measurements. Our cases showed changes immediately surgery without intraoperative fixation.
