Abstract
Background: Although medical management with continuous positive airway pressure (CPAP) remains the standard treatment for obstructive sleep apnea (OSA) patients, many patients are either unable to tolerate or do not want CPAP therapy, and thus, surgery remains a viable option. Surgical therapy has historically been classified into phase I (multi-level, supposedly less invasive) and phase II (maxillomandibular advancement- MMA) surgery.1 Common phase I surgery procedures include uvulopalatopharyngoplasty (UPPP), hyoid suspension (HMS), genioglossus advancement (GBAT), and radiofrequency ablation. While MMA surgery has been shown to be the most successful2, phase I surgery remains the recommended preliminary treatment due to its less invasive nature.
