Objective: Our aim in this study is to investigate the accompanying otolitic organ dysfunctions in BPPV by examining the findings of cVEMP, oVEMP and vHIT in posterior canal benign paroxysmal vertigo (BPPV).

Method: In the study, the findings of cVEMP, oVEMP and vHIT in posterior canal BPPV were examined.. A study group was formed from 36 posterior canal BPPV patients and a control group from 42 healthy volunteers.. The latency (ms), amplitude values (uV) and asymmetry ratios of the waves obtained in cVEMP and oVEMP were evaluated. VOR gains in the affected posterior SCC in vHIT were examined.

Results: P1 and N1 latencies did not significantly differ between the control group and the values obtained before and after the maneuver in the cVEMP test.. The P1-N1 amplitude, which was 84.75 µV before and 89.64 µV before the maneuver, was found to be significantly lower than the P1-N1 amplitude of 110.39 µV in the control group (p<0.05). The P1 latency measured at 15.11 ms after the maneuver was longer than 14.59 ms in the ovemp test before it. (p<0.05). In vHIT, there was no statistical difference between the pre- and post-maneuverion VOR gain values, and also between the patient and control groups.

Conclusion: It was concluded that VEMP tests can be used as an aid in the follow-up of BPPV patients, that low P1-N1 amplitude obtained in cVEMP may be an indicator of saccule dysfunction and prolongation of P1 latency in oVEMP may be an indicator of utricle dysfunction.
