 We investigated the correlation between the vHIT of the horizontal canal, the caloric test, and the cVEMP, in 45 patients diagnosed with vestibular neuritis or unilateral vestibular neuroma. There was a strong correlation between the results of the vestibulo-ocular reflex(VOR)gain asymmetry in the horizontal canal vHIT and the percentage of canal paresis in the caloric test. However, no correlation between the results of the VOR gain asymmetry on the horizontal canal vHIT and the cVEMP response was observed. Using results of the horizontal vHIT, we can estimate the functional roles of the horizontal semicircular canal and the superior vestibular nerve;however, this test cannot be used to investigate the inferior nerve function.
