Abstract:
OBJECTIVE:To investigate the value of video laryngoscope in localization diagnosis of upper airway stricture in obstructive sleep apnea-hypopnea syndrome (OSAHS) during drug-induced sleep.
METHOD:One hundred and thirty two patients with OSAHS were randomly divided into group A and B in this study. In group A, the patients were examined with video laryngoscope to locate the upper airway stricture under midazolam-induced sleep. In group B, the patients had conventional physical examination and video laryngoscope when awake. And the operation plans of both groups were made based on the localization diagnosis results.
RESULT:In group A, 72.1% patients have several stricture levels and in group B only 33.8%. The patients was followed up time more than 6 months, and the cure rate, the excellent effective rate, and the total effective rate of group A were significantly higher than those in group B respectively (P<0.05).
CONCLUSION:Most patients of OSAHS have several stricture levels of upper airway under Midazolam- induced sleep. Localization diagnosis of upper airway stricture in patients with OSAHS with video laryngoscope before operation can improve the cure efficiency significantly.
