Introduction: Systemic arterial hypertension is a highly prevalent disease in our society afflicting around 15% to 20% of the adult population aged 18 years and over. Symptoms as headache, dizziness, tinnitus, and weakness are usually regarded as effects of high blood pressure. Aim: This research aims at verifying existence alterations of the vestibulocochlear system in individuals suffering from systemic arterial hypertension. Methodology: The study group consisted of 19 systemic arterial hypertension patients, 7 men and 12 women, with ages ranging from 38 to 59. The control group consisted of 19 matched healthy individuals. They were submitted to anamnesis, basic hearing evaluation, and computerized vectoelectronystagmography (VENG). Results: the complaint about tinnitus was presented in 63,16% of the suffering HAS patients and in 42,10% in the group control individuals. In the hypertension patients group, 52,63 % have presented complaints about dizziness and 31, 58% in the group control patients. The hearing evaluation has presented alteration in 42,11% of the suffering HAS patients. None individual in the group control has presented alteration in the hearing evaluation. In VENG s conclusion, 57, 89% of the suffering HAS patients presented vestibular exam with no alteration, 26, 32% presented some alteration as the peripheral vestibular hyperfunction syndrome and 15, 79% of the patients presented peripheral vestibular hypofunction syndrome. In the group upon control, 84, 21% of the patients presented vestibular exams with no alteration, 10,53% presented alteration as the peripheral vestibular hyperfunction syndrome and only 5,26% presented alterations as the peripheral vestibular hypofunction syndrome. Conclusion: hypertension individuals presented major incidence in the hearing alteration in the vestibularcochlear system than non-hypertension individuals.
