Objective To investigate the consistency of the sources of snoring sound induced by simulated snoring and drug-induced sleep endoscopy in simple snores( SS) and mild obstructive sleep apnea / hypopnea syndrome( OSAHS).Methods A total of 40 cases diagnosed as either SS or mild OSAHS by polysomnography( PSG) underwent simulated snoring and drug-induced sleep endoscopy successively. The vibration of soft tissue of upper airway was observed with fiberoptic laryngoscope. Results Under simulated snoring condition and drug-induced sleep endoscopy,there were different vibrations in the pharynx. The Mc Nemar statistical results showed that there was no significant difference between simulated snoring and drug-induced sleep endoscopy in determining the vibration of soft palate and epiglottis / tongue base( P = 0. 774,0. 077),while there was very significant difference between the two methods in determining the vibration of the lateral phaynged wall( P = 0. 002). Under these two conditions,there was no significant difference in the incidence rates of vibration of both soft palate and epiglottis / tongue base( P = 0. 770,0. 110),while the incidence rate of vibration of lateral pharyngeal wall was much higer under drug-induced sleep endoscopy than that under simulated snoring( P = 0. 005). Conclusion Compared with drug-induced sleep endoscopy,simulated snoring is relatively reliable in determination of soft palate vibration,slightly inferior for epiglottis / tongue base,but is unreliable in the determination of lateral pharyngeal wall vibration.
