Apnea hypopnea index in healthy Class III patients treated with intraoral vertical ramus osteotomy: a prospective cohort study.

To assess if mandibular setback surgery by intraoral vertical ramus osteotomy (IVRO) induces obstructive apnea and hypopnea in healthy, Class III patients without a history of respiratory dysfunction. The authors hypothesized that apnea hypopnea index (AHI) did not exceed 5 events/hour after surgery.
