Sintomas otoneurológicos e resultados do vídeo teste do impulso cefálico em pacientes com migrânea vestibular

Abstract

Introduction: Vestibular migraine (VM) is a disease that affects the central nervous system. The video head impulse test (VHIT) can help in the differential diagnosis. Purpose: To characterize otoneurological symptoms and vHIT findings in patients with nosological diagnosis of VM. Methods: Retrospective and descriptive study, approved by the Research Ethics Committee, opinion nº4,462,519. Eighteen medical records of individuals diagnosed with the disease who underwent the vHIT were studied, and information related to complaints, anthropometric data, comorbidities, results of the vHIT and the audiological examination were collected. Results: In the sample, fourteen (77.7%) were female and four (22.2%) were male, with a mean age of 46.6 years. Symptoms of migraine, vertigo, nausea, phonophobia and tinnitus predominated. Regarding the VHIT, 12 patients (66.6%) had results within normal limits and 6 (33.3%) had hypofunction. Among the 13 patients who underwent an audiological evaluation, hearing was found to be within normal limits for 9 (69.2%), 4 (30.7%) had mild sensorineural hearing loss. Conclusion: In this study, there was a predominance of VM in women, with symptoms of migraine, vertigo, tinnitus and nausea, confirming the vestibular nature of the disease. Regarding VHIT and pure tone audiometry, there was a higher occurrence of results within normal limits.
