ClinConnect Summary

Bimaxillary orthognathic surgery is a surgical procedure that involves simultaneous correction of both the maxilla (upper jaw) and the 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 discrepancy between the upper and lower jaws or significant 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 proxim...

Eligibility criteria

• Inclusion Criteria:
• • 1. Patients planned to undergo bimaxillary orthognathic surgery with Class III skeletal deformity
• • 2. Patients aged 18-65
• • 3. Patients who have undergone preoperative orthodontic treatment
• • 4. Patients who, after mandibular distal segment sagittal split osteotomy, exhibit a maximum of 4 degrees of counterclockwise rotation when brought to the final position
• Exclusion Criteria:
• • 1. Patients with a history of joint surgery, orthognathic surgery, or tumor resection
• • 2. Patients with facial asymmetry
• • 3. Patients with cleft lip and palate syndrome, craniofacial syndrome, or trauma
• • 4. Patients who, after mandibular distal segment sagittal split osteotomy, exhibit more than 4 degrees of counterclockwise rotation when brought to the final position (as the amount of base resection required in this case would exceed feasible limits).
