[Effects of diazepam on stapedius reflex: physiological research].

The effect of diazepam (10 mg i.m. X 7 days) on crossed and uncrossed acoustic stapedius reflex parameters (threshold, amplitude and duration) has been studied in 7 normal hearing subjects. The results showed that diazepam has a not clinically significant damping effect on the threshold, the amplitude and, very often, the duration of both ipsilateral and contralateral acoustic stapedius reflexes.
