The evaluation of the impacts of Behcet's disease on vestibular system with video head impulse test

Introduction Behcet's disease (BD) is a vasculitis, which involves all small vessels, and influences the multiple systems of the human body. Latest studies mentioned the impact of BD on vestibular system, as well. This study aims to compare the vestibular system results of BD patients and healthy individuals. Material and Method This study was held after the approval of local ethical committee (Baskent University Medical Faculty non-invasive Clinical Studies Center, K17/136 project number). 31 patients, which were diagnosed with BD, and 31 healthy individuals were involved to the study. All the subjects were evaluated via pure tone audiometry, video head impulse test (vHIT), post head shake nystagmus test (pHSNT) and dizziness handicap inventory (DHI) to check for vestibular system integrity. The data was analyzed according to proper statistical method. Results The vestibular system was significantly affected in Behcet patients. In vHIT, 12.9% of patients had overt and covert saccade on left lateral semicircular canal and 25,81% of patients had overt and covert saccade at the right lateral semicircular canal. In pHSNT, catch up saccade and presence of nystagmus were revealed in patients and patients had also hearing loss in pure tone audiometry. DHI results of patients were found significantly high. Conclusion vHIT, which is a short and reliable, may be an alternative test to assess the vestibular system. The affection of the vestibular system was revealed in the patients before the neuro-Behcet appearance. a doldurulacaktır.
