OBJECTIVE: To investigate whether @entity5570 in M  ni  re's Disease could be diagnosed by comparing vestibular evoked myogenic potential (VEMP) before and after @entity1483 administration (F-VEMP). STUDY DESIGN: Retrospective study. SETTING: University hospital. INTERVENTION: @entity1483 administration. @entity1 : Twenty-five affected ears of @entity1 with unilateral M  ni  re's Disease were studied. The @entity1 had received confirmed diagnoses M  ni  re's Disease; thus, the presence of @entity5570 was suggested. For the control, 22 ears of 11 normal healthy volunteers who had never had vertigo or hearing disturbance were used. MAIN OUTCOME MEASURE: The amplitude of the @entity4668 -n23 biphasic wave before and after @entity1483 administration. RESULTS: The amplitude of the @entity4668 -n23 biphasic wave was significantly enlarged in 7 of 18 cases in which it could be detected before diuretic loading. The biphasic waves appeared after diuretic loading in 3 of 7 cases in which it could not be recorded before loading. Thus, the positive ratio of F-VEMP for unilateral M  ni  re's Disease was considered to be 40% (10 of 25). The ratio was similar to that of the conventional examinations for @entity5570 such as the @entity653 test, @entity1483 test, and electrocochleogram. CONCLUSION: The F-VEMP test may be useful in the diagnosis of @entity5570 .
