Bimaxillary Orthognathic Surgery with Anterior Segmental Osteotomy for Skeletal Class III with Mild Obstructive Sleep Apnea: A Case Report
Skeletal Class III deformity with coexisting obstructive sleep apnea presents a surgical challenge, as mandibular setback may improve facial balance but potentially compromise the upper airway. This case report describes bimaxillary orthognathic surgery combined with anterior segmental osteotomy for a patient with skeletal Class III malocclusion and mild obstructive sleep apnea. The treatment plan aimed to correct maxillomandibular discrepancy, improve dental protrusion, and maintain airway stability. Maxillary advancement, mandibular repositioning, and anterior segmental osteotomy were performed to achieve functional occlusion and facial harmony. Postoperatively, the patient demonstrated improved skeletal relationship, stable occlusion, enhanced facial profile, and no deterioration of sleep-related symptoms. This case highlights the importance of airway-conscious surgical planning in Class III correction.
