Otoacoustic emissions evoked in Ménière's disease

ABSTRACT Purpose To verify the responses of Evoked Otoacoustic Emissions by transient stimulus and distortion product in individuals with Ménière’s Disease. Methods Cross-sectional study a sample composed 60 individuals, aged 19 to 75 years, divided into two groups: group, 32 medical diagnosis disease, without other risks control group formed 28 cochlear loss Meniere’s age sex matched group. Eligibility criteria: type A curve, conductive or mixed suspected retrocochlear alteration. The audiological evaluation consisted anamnesis, inspection external acoustic meatus, pure tone audiometry, logoaudiometry, measures immittance evoked otoacoustic emissions product. Results Individuals disease had higher occurrence unilateral hearing loss, low pitch tinnitus, vertigo ear fullness relation control. In these there was greater incompatibility between results OAE audiometry: alterations were observed ears normal thresholds on contralateral side, characterizing dysfunctions. presence TEOAE absence DPOAE, contrast which showed as expected losses etiologies. Conclusion investigation identified dysfunction cases TOAE DPOAE differentiating from
