Effect of Proximal Segment Positioning on Condylar Remodeling

The Effect Of Different Proximal Segment Positioning Methods On Postoperative Condylar Remodeling in Patients Undergoing Bimaxillary Orthognathic Surgery

Sponsor

40 participants

Start Date

Study Type

INTERVENTIONAL

Conditions

Orthognathic Surgical Procedures

Summary

This study aims to evaluate postoperative condylar remodeling in patients undergoing bimaxillary orthognathic surgery by comparing two different proximal segment positioning techniques used during mandibular osteotomy. Condylar remodeling will be assessed using preoperative, immediate postoperative, and 6-month postoperative computed tomography (CT) scans together with clinical findings.

Plain Language Summary

Simplified for easier understanding

This clinical trial is studying a procedure called Inferior Border Osteotomy Without Proximal Segment Rotation and a procedure called Proximal Segment Rotation for people with orthognathic surgical procedures. The study is currently recruiting participants at 1 location. People eligible for this study include aged 18 Years to 65 Years.

Interventions

PROCEDUREProximal Segment Rotation

During bimaxillary orthognathic surgery, after bilateral sagittal split osteotomy (BSSO), the proximal mandibular segment is rotated to achieve alignment of the inferior border of the proximal and distal mandibular segments before rigid fixation.

PROCEDUREInferior Border Osteotomy Without Proximal Segment Rotation

During bimaxillary orthognathic surgery, after bilateral sagittal split osteotomy (BSSO), the proximal mandibular segment is maintained in its preoperative position. Alignment of the mandibular inferior border is achieved by performing an additional osteotomy at the inferior border of the proximal segment without rotating the proximal segment before rigid fixation.
