The significance of stapedial reflex test in facial nerve paralysis.
The stapedial reflex of 30 patients with peripheral facial nerve paralysis was compared with the results of facial paralysis scores. The stapedial reflex was measured with an oto-reflex analyser, RS-06A. The stimulation frequencies in the stapedial reflex test were 500, 1,000 and 2,000 Hz for both ipsilateral and contralateral stimulation. The stapedial reflex test at 500 Hz for contralateral stimulation seemed to be useful for evaluating the degree of facial paralysis. With 500 Hz or 1,000 Hz contralateral stimulation, the stapedial reflex test seemed to be useful for predicting the prognosis for facial nerve paralysis. In these stimulations, cases with a positive reflex within 2 weeks showed complete recovery within 12 weeks, and cases with positive reflex within 4 weeks showed recovery within 24 weeks.
