ABSTRACT
Abstract

Introduction:

A considerable high number of SNHL patients also suffer from dizziness and related vestibular symptoms.

Objective:

To evaluate the association of vestibular dysfunction and sensorineural hearing loss (SNHL) in adult patients.

Methods:

Prospective, double-blinded, controlled studies composed by 63 adult patients without any vestibular symptoms or diagnosed vestibular diseases. Audiological status was measured with pure tone audiometry and the vestibular system was tested with vestibular evoked myogenic potential (VEMP). Patients were divided into two groups a study group (patients with SNHL) and a control group (patients without SNHL). VEMP results of the groups were calculated and compared.

Results:

Mean P1 (23.54) and N1 (30.70) latencies were prolonged in the study group (p < 0.001) and the amplitudes of the study group were significantly reduced (p < 0.001). Both parameters of the VEMP test were abnormal in the study group when compared to the control group.

Conclusions:

These findings suggest that age-related SNHL may be accompanied by vestibular weakness without any possible predisposing factors for vestibulopathy.
RESUMO
Resumo

Introdução:

Um número considerável de pacientes com PANS também sofre de tonturas e sintomas vestibulares relacionados.

Objetivo:

Avaliar a associação entre disfunção vestibular e perda auditiva neurossensorial (PANS) em pacientes adultos.

Método:

Estudo prospectivo, duplo-cego e controlado com 63 pacientes adultos, sem quaisquer sintomas vestibulares ou doença vestibular diagnosticada. A audição foi avaliada por meio de audiometria tonal e o sistema vestibular, com potenciais evocados miogênicos vestibulares (PEMV). Os pacientes foram divididos em dois grupos grupo de estudo (pacientes com PANS) e grupo de controle (pacientes sem PANS). Os resultados dos PEMV dos grupos foram calculados e comparados.

Resultados:

As latências médias de P1 (23,54) e N1 (30,70) encontravam-se prolongadas no grupo de estudo (p < 0,001), e as amplitudes no grupo de estudo estavam significantemente reduzidas (p < 0,001). Ambos os parâmetros do teste de PEMV foram anormais no grupo de estudo quando comparados aos do grupo controle.

Conclusões:

Nossas achados sugerem que a PANS relacionada à idade pode ser acompanhada por hipofunção vestibular, mesmo na ausência de possíveis fatores predisponentes para vestibulopatia.
