Abstract
Conclusions: Patients with positive results of furosemide-loading vestibular evoked myogenic potential (F-VEMP) testing in the unaffected ears of unilateral Meniere's disease have a high incidence of developing bilateral lesions. Objective: To clarify the meaning of positive results of F-VEMP testing of the unaffected ear of patients with unilateral Meniere's disease. Methods: Twenty-five patients with unilateral Meniere's disease were investigated in this study. The positive group consisted of 6 patients with positive results of F-VEMP testing in the contralateral ear and the negative group consisted of 19 patients with negative results. The incidence of contralateral involvement was compared in both groups by the Kaplan–Meier method. Results: Contralateral involvement was seen in three cases (50%) in the positive group after 2, 12, and 26 months and in three cases (16%) in the negative group after 27, 56, and 78 months. The positive group had a higher incidence of contralateral involvement than the negative group (p = 0.0017, according to a log-rank test).
