[Compare the value of video laryngoscope in localization diagnosis of upper airway stricture in obstructive sleep apnea-hypopnea syndrome between awake and drug-induced sleep].
OBJECTIVE
To compare the value of video laryngoscope in localization diagnosis of upper airway stricture in obstructive sleep apnea-hypopnea syndrome (OSAHS) between awake and drug-induced sleep.


METHODS
Ninety-eight patients of OSAHS were examined with video laryngoscope to locate the upper airway stricture under awake and Midazolam-induced sleep.


RESULTS
The several stricture levels under awake was 58.2% and it was 77.5% under drug induced sleep.


CONCLUSIONS
Several stricture levels of upper airway were founded in most of the patients of OSAHS. The upper airway stricture levels was more in the sleep than in the wake.
