“…Only one previous study showed that VOR gain increases in BD patients [1], but in the study of Ertugrul et al the RALP VOR gain was significantly lower and the gain asymmetry ratio of lateral SCCs was significantly higher in BD patients compared to the control. They also reported a significant occurrence of pathological covert and overt saccades in lateral SCCs stimulation in BD patients [22]. However, in our study, the percentage of covert and overt corrective saccades was higher in vertical canals than the horizontal canals, while there was no significant difference between the two study groups in terms of the occurrence of corrective saccades.…”

“…Brama and Fainaru also stated that inner ear involvement is often seen in elderly BD patients with a longer duration of disease despite the health of the CNS [28]. Other researchers found no correlation between age and disease duration with audiovestibular disorders [1,3,6,14,22].…”

“…In addition, one of the unique advantages of vHIT over the videonystagmography (VNG) and rotatory chair tests is that it can record very small backup saccades that are indicative of disorder in the central vestibular system and therefore can differentiate between peripheral and central lesions of the vestibular system. Many studies have confirmed the use of this test in the diagnosis of neurological disorders [21,22]. The most valid method for evaluating the function of the anterior and posterior SCCs involves combining the vHIT and scleral coil technique [17].…”

“…However, only two studies have performed this test in patients with BD. Ertugrul et al reported a reduction in VOR gain in the stimulation of right anterior-left posterior (RALP) SCCs and also a higher asymmetry ratio in the test of lateral canals in BD patients than the controls [22]; while Tutar et al reported only a reduction of the VOR gain of left anterior, left posterior and right posterior SCCs, and found no difference in the asymmetry ratio of BD patients and normal controls [23].…”

Background and Aim: Behcet’s disease (BD) is a multisystemic, chronic and progressive disorder with a relatively high prevalence in Iran. Therefore, this study aimed to compare the vestibular function between Iranian BD patients and normal subjects using cervical vestibular- evoked myogenic potentials (cVEMPs) and video head impulse test (vHIT). Methods: In this cross-sectional study, 44 patients with definitive BD in the inactive stage of disease and 30 age and sex matched normal subjects were evaluated via cVEMP and vHIT tests and dizziness handicap inventory (DHI). Then the parameters of the tests were compared between the two groups by statistical methods. Moreover, the effects of DHI scores and other contextual variables on the test results were examined. Results: In terms of the cVEMP test, the response rate and mean latency of p13 in the left ear were significantly lower, the amplitude of the cVEMP wave in the left ear and the amplitude asymmetry ratio were significantly higher in BD patients compared to normal subjects (p<0.05). Fifteen BD patients had abnormal amplitude and nine patients had abnormal latency of cVEMP responses. In terms of the vHIT test, the mean vestibule-ocular reflex gain of the left posterior semicircular canal and the mean gain asymmetry ratio of lateral canals were significantly higher in BD patients than in the controls (p<0.05). Conclusion: the vestibular system of some patients with BD is disturbed and the results of this study indicate the presence of unilateral vestibular weakness in BD. So vestibular assessment can be helpful for these patients. Keywords: Cervical vestibular evoked myogenic potentials; video head impulse test; saccule; semicircular canals; behcet’s disease

“…21,22 A study by Ertugrul et al used vHIT to evaluate 31 BD cases. 23 They performed PTA, vHIT, posthead shake nystagmus test (PHSNT), and dizziness handicap inventory (DHI) to check for audiovestibular system involvement. Saccades were detected only in the horizontal semicircular canals.…”

Behçet's disease (BD) is characterized by recurrent oral and genital ulcers, uveitis and vasculitis throughout the body. There are not many studies in the literature on the involvement of the vestibular system in BD. Our aim is to evaluate the vestibular system in Behçet's patients and to determine the clinical importance of video head impulse test (vHIT). Material and Methods: Twenty patients (11 females and nine males) with BD and 15 healthy volunteers (seven females and eight males) were included in the study. Pure tone audiometry (PTA), videonystagmography (VNG), dizziness handicap inventory (DHI) and vHIT tests were administered to all individuals. Data were evaluated by statistical methods. Results: The mean age of the patients with BD was 44±11.2 years, and the mean age of the healthy volunteers was 42±13.3 years. The DHI scores of the patient group were higher than the control group. Results of vHIT showed significantly lower VOR gain in the left lateral, right, and left posterior semicircular canals in the BD group compared to the control group. Nine (45%) of the BD patients had overt saccade, but none had covert saccade. Overt and covert saccade were not observed in the healthy volunteers. Conclusion: vHIT is a fast and accurate test that can be used to evaluate the vestibular system in patients with BD.
