OBJECTIVES To verify the effects of oral appliance (OA) on upper airway morphology under intraluminal pressure, identify specific sites of upper airway collapsibility that can be reversed by OAs,and determine the relationship between OA efficacy and dynamic upper airway changes using computed tomography (CT) with Mullers maneuver.MATERIALS AND METHODS Nineteen adult Chinese patients with symptomatic mild-to-moderate sleep apnea were recruited from our sleep center.Each patient was fitted with a two-piece OA.Dynamic changes in the retropalatal and retroglossal airway were evaluated using CT at end-expiration and during Mullers maneuver,both with and without an OA.
