Pure tone audiology for Meniere disease: a clinical analysis of 75 cases

Objective To analyze clinical pure tone test data in patients with Meniere disease and study the changes in the audiometic curve configuration.Methods A retrospective analysis was conducted of the pure tone test data in 75 cases(82 ears) from 1984 to 2008.The audiometic curve configuration was divided into 6 categories to analyze the relationship between the main curve types and the clinical stages.Results The most common audiogram was the peak type(46.34%),followed by the falling type(19.51%) and the mountain type(12.19%),and the dip type was relatively rare(2.43%).No significant differences were found in the rate of peak audiograms between the clinical stages.The common audiogram peak frequency occurred at 2 kHz(47.39%).The top curve of 1~2 kHz had the largest proportion in mountain type audiograms(70%,7/10 ears).Conclusion The peak type and mountain type configuration are one of the audiological characteristics of Meniere disease,especially for 2 kHz peak,which may serve as the diagnostic features of Meniere disease in the vertigo patients on their first visit.
