Abstract
We investigated the course of Meniere's disease by questionnaires sent to 94 patients in June 1992. Sixty-seven of them sent back information as to whether they still had attacks of vertigo and whether they had been treated since they visited our clinic between 1981 and 1986.
On the basis of their responses, they were divided into 2 groups: those who had not been treated or had been treated only when they had attacks of vertigo (natural course group) and those who had been treated for a certain period (treated group).
We judged that they were cured of vertigo if the period without attacks was over 2 years and longer than their maximum attack-free intervals. The percentage of cures was similar in the 2 groups, but the time between the first and the last attack of vertigo was longer in the natural course group than in the treated group.
