[The correlation between the hearing frequency and staging of Meniere's disease]

Objective: To study the relationship between the average hearing of different frequencies and the audiometry staging in patients with Meniere's disease. Methods: A total of 259 patients from 1996 to 2016 were collected .All patients underwent pure tone audiometry, of which 93 patients underwent 3 000 Hz audiometry. The patients were divided into five groups according to the frequencies of hearing(Ⅰ: 500, 1 000, 2 000, 3 000 Hz; Ⅱ: 250, 500, 1 000, 2 000, 3 000 Hz; Ⅲ: 250, 500, 1 000, 2 000; Ⅳ: 500, 1 000, 2 000, 4 000 Hz; Ⅴ: 500, 1 000, 2 000 Hz), then calculated the average audiometry and made the hearing staging. The obtained data were analyzed by chi-square test and Bonferroni correction was performed among the groups, P<0.05 was defined as a statistically significant criterion. Result: There were no significant difference between the five groups(P=0.441>0.05). Conclusions: The choice of different pure tone audiometry frequency has no significant effect on the hearing staging. It would be more likely upstaging when plus 250 Hz. There is no statistically significant difference in staging between the latest guidelines and the 1995 guidelines.500, 1 000 and 2 000 Hz are recommended when 3 000 Hz examine is not available.
