Resolution of obstructive sleep apnea following facial surgery

Compared to uvulopalatopharyngoplasty (UPPP), maxillo-facial surgery is rarely performed in Canada for treatment of obstructive sleep apnea. However, in patients with retrolingual obstruction, UPPP cannot be expected to result in good surgical outcome. We describe a patient with retrognathia causing airway obstruction at the base of the tongue, in whom sagittal mandibular osteotomy with hyoid bone advancement resulted in resolution of snoring and sleep apnea.
