Özet
Aim: In this study, we aimed to investigate the effect of betahistine dihydrochloride (BD) use on positional nystagmus as an objective criterion for the diagnosis of benign paroxysmal positional vertigo (BPPV). Methods: The retrospective study included 59 patients (15 males, 44 females) who were aged between 18 and 80 years and referred with suspected BPPV to the otorhinolaryngology clinic of the Istanbul Training and Research Hospital. Only patients who had no central pathology on oculomotor tests were included. Of the patients included, those not using BD were classified as Group I and those using BD medication (24 mg/day) within the last 48 hours as Group II. The positional nystagmus latency, duration, and slow-phase velocity (SPV) values were compared using videonystagmography. Results: There was no significant difference between the two groups in terms of oculomotor gains (p>0.05). While there was no difference between the two groups in terms of positional nystagmus latency and SPV values, nystagmus duration was found to be significantly longer in Group II. Conclusion: Although the BD use appears to prolong the duration of nystagmus in BPPV, it does not affect the other parameters of nystagmus, including SPV, and the prolonged duration is still within normal limits. Positional nystagmus can be investigated in patients with a history of suspected BPPV and BD prescription.
