【 摘 要 】
Otoneurological evaluations are based on tests which investigate auditory and vestibular disorders, including brainstem evoked auditory potentials and vecto-electronystagmography. AIM: to describe the results from the otoneurological assessment of patients with vestibulocochlear complaints, normal hearing individuals and patients with hearing loss, and we will compare them to a control group. MATERIALS AND METHODS: Cross-sectional, retrospective, observational study, held with 56 dizzy patients assessed by means of audiometry, vecto-electronystagmography and brainstem evoked auditory potential, broken down into Group A, with 31 normal-hearing individuals and Group B with 25 hearing loss patients, compared to the control group made up of ten normal-hearing asymptomatic individuals. RESULTS: Patients from groups A and B were compared to the Control Group, although with values within the normal range. A common finding for both groups was the lack of wave I at 80 dBHL and it happened bilaterally in four individuals (12.9%) and unilaterally in three (9.6%) for Group A; and bilaterally in eight individuals from Group B (32%). In the two cases in which vecto-electronystagmography showed central vestibular alteration, there were no changes to the evoked potential parameters. CONCLUSION: patients with vertigo, normal-hearing and hearing loss individuals had increased absolute latencies when compared to the Control Group
