Abstract
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.
