Effect of Proximal Segment Positioning on Postoperative Condylar Remodeling in Bimaxillary Orthognathic Surgery

Sponsor: Bezmialem Vakif University

Summary

Bimaxillary orthognathic surgery is a surgical procedure that involves simultaneous corrections to both the maxilla (upper jaw) and mandible (lower jaw). This surgery is performed to correct facial and jaw deformities, improve occlusion, and enhance facial symmetry. The need for orthognathic surgery typically arises in cases where there is a significant discrepancy between the upper and lower jaws or severe malocclusion. In bimaxillary orthognathic surgery, following mandibular osteotomies, the lower jaw is divided into two segments: the distal segment, which contains the teeth, and the proximal segment, which includes the condylar head. While the distal segment is positioned according to the ideal occlusion planned in collaboration with orthodontists using digital design, the management of the proximal segment varies among surgeons. Some surgeons leave the proximal segment in its original position without mobilization, whereas others reposition it through rotational movements. This study aims to evaluate condylar remodeling by comparing these two surgical approaches in patients divided into two groups, assessing how each technique affects postoperative outcomes.
