ABSTRACT
Background and Objectives:   Diagnosis of Meniere’s disease (MD) is based on detailed medical history and audiometry in addition to electrocochleography (ECoG). However, the sensitivity of ECoG is rather low and the diagnosis seems to be rather obscure if the patient is evaluated after resolution of acute symptom, especially in early stage of disease without substantial hearing loss. In such cases, if a patient complains recurrent episodes within short term period, any objective result would be beneficial to initiate medical treatment such as diuretics. Since the saccule is the main target organ in MD, authors suppose vestibular evoked myogenic potential (VEMP) test combined with ECoG may elevate the diagnostic sensitivity in MD. Aim of study is to evaluate the possibility of this suggestion.
Materials and Method:  
Thirty-four patients of unilateral MD who have hearing loss less than 40 dB and onset of first attack within 1 year were included in this study. They underwent VEMP, caloric test and ECoG. Abnormal rates of each test and results of combination were analyzed according to the group of MD.
Results:  
Patients with abnormal results in VEMP, ECoG and calorict tests were 29%, 15% and 35%, respectively. Patients showed abnormal results either in VEMP or ECoG were 41% in all MD and 72% in definite group.
Conclusions:  
To get higher objective evidence of cochleovestibu
