ABSTRACT
Objective To investigate the characteristics and clinical significance of ocular vestibular evoked myogenic potential (oVEMP) and caloric test in Meniere disease (MD) at different hearing stages.Methods Fifty-five patients(52.8±15.8 years old) with MD were divided into stage 1(9 cases,48.8±13.8 years old), stage 2(9 cases,46.0±16.3 years old), stage 3(23 cases,50.3±13.5 years old) and stage 4(cases 14, 53.5±16.2 years) respectively according to the pure tone audiometry.They were evaluated by oVEMP and caloric test.Results The abnormal rates of oVEMP were 55.6%, 66.7%, 78.3%, 78.6%,and caloric tests were 22.2%, 33.3%, 78.3%,and 85.7% respectively in stage 1, 2, 3, and 4 MD patients.The amplitudes of oVEMP in stage of 1, 2, 3, and 4 MD patients were 4.3±4.0 μV,3.5±2.3 μV,2.5±2.4 μV,and 1.3±0.5 μV,respectively.Conclusion The abnormal rates of oVEMP and caloric tests in MD patients increased with the degree of hearing impairment and the amplitudes of oVEMP were decreased, suggesting that utricle and horizontal semicircular canal injuries were aggravated.
