Objectives: Analyze the condylar position with inter-condylar distance and angle after bimaxillary orthognathic surgery with counterclockwise rotation in Class II deformities applying cone-beam computed tomography (CBCT) images before and after surgery.

Materials and methods: A pilot study with 40 analyses from 5 patients undergoing the described surgery between 2011 and 2012 were analyzed. CBCT scans were performed before and after surgery. The exported DICOM data were analyzed with Dolphin Imaging 11.5 software to measure the alterations in the height of the condyles and changes in the intracapsular space. Patients were also asked about TMJ problems.

Results: There was no significant difference between the pre-and postoperative distances between condylar centers (p>. 05) and intercondylar angle.

Conclusions: Our cases showed no significant changes of condylar position and morphology …
