The value of computer fiber optic pharygoscopy with Muller's maneuver in diagnosis of obstructive sleep apnea hypopnea syndrome

Objective analyze the correlation between the obstructive abnormalities of upper airway that examined by computer fiber optic pharygoscopy with Muller's maneuver(CFPMM)and outcomes of polysomnography(PSG).Methods fifty-six patients with obstructive sleep apnea hypopnea syndrome(OSHAS)and fifteen patients without it both underwent the examination of CFPMM and PSG,compare the outcomes of each group,meanwhile studied the correlation between the pharyngeal collapsibility of fifty-six patients with OSAHS and PSG outcomes that included apnea and hypopnea index(AHI)、SpO2,etc.Results pharyngeal collapsibility,which examined by CFPMM were associated with increased rates of AHI(P0.05).Conclusion CFPMM not only can reflect the severity of OSAHS,but also directly observe the content and location of pharyngeal collapsibility.
