Abnormalities in saccule was the second most common finding in histopathology study. The previous studies showed inconsistent results in saccular function.</p><p><strong>Objective</strong> : To evaluate saccular function in definite Meniere’s disease patients by cervical vestibular evoked myogenic potential (cVEMP).</p><p><strong>Method</strong> : A cross-sectional study conducted at King Chulalongkorn Memorial Hospital. All patients in control group and definite Meniere’s disease underwent cVEMP. Four parameters of cVEMP include P1 latency, N1 latency, P1-N1 amplitude and amplitude asymmetry ratio were evaluated.</p><p><strong>Result</strong> : Twenty-two definite Meniere’s disease and thirty control patients were included in the study. The median duration of Meniere’s disease was 36 months. Nineteen of twenty-two Meniere’s disease patients (86.36%) obtained absence cVEMP in affected ear. The mean latency of P1, N1 and P1-N1 amplitude were not statistically significant different between control group and unaffected ear of Meniere’s disease group (mean difference = 0.73, 95% CI = -1.55, 0.08, p = 0.074; mean difference = 0.25, 95% CI = -1.23, 0.74, p = 0.62; mean difference = -5.45, 95% CI -1.44, 12.34, p = 0.12, respectively). Three Meniere’s disease patients who cVEMP presented in affected ear showed amplitude asymmetry ratio of 24.4%.</p><p><strong>Conclusions</strong> : Patients with definite Meniere’s disease usually demonstrated absent cVEMP response.</p> ER -
