Abstract:
The purpose of this study was to assess the diagnostic value of main frequency of transient evoked otoacoustic emissions for Meniere's disease. The click- evoked transient otoacoustic emissions(TEOAE) in normal subjects and in patients with Meniere' s disease were examined using ILO 88 otodynamic analyzer system to observe the main frequency distrbution. The main frequeencies ranged from 1.2 to 1.6 kHz in normal ears, and from 0.8 to 1. 1 kHz in Meniere' s ears. The main frequency range of normal ears was obviously higher than that in Meniere's ears. After application of glycerol, the main frequencies in some Meniere's ears were shifted from relative low frequency range to relative high frequency range. TEOAE appeared in some Meniere's ears in which TEOAEs could not be evoked before application of glycerol. The results suggest that the TEOAE can be used in the diagnosis of Meniere's disease.
