Evaluation shows stability after bimaxillary orthognathic surgery for skeletal class III malocclusion in cleft lip patients, suggesting effective correction of jaw alignment.
Bimaxillary surgery is an effective method for correcting skeletal Class III malocclusion in patients with cleft lip and palate. The planned surgical movement of the mandible via bilateral sagittal split osteotomy (BSSO) with setback allows for compensatory reduction in the required maxillary advancement during LeFort I osteotomy. This approach may potentially reduce the extent of anteroposterior relapse in the maxilla.
