Answer

Answer

Otolaryngologists use numerous modalities to locate the site of snore-sound generation and obstructive locations. These tools include a complete head-and-neck exam, the Müller maneuver, lateral radiographic cephalometry, computed tomography (CT) scanning, and magnetic resonance imaging (MRI). The static nature of these exams, coupled with increased resting muscle tone while the patient is awake, makes pinpointing the source of true obstruction difficult. While each of these methods offers reasonable diagnostic efficacy, none offers direct and dynamic visualization of pharyngeal structures during sleep.
