OBJECTIVE:
Compare the caloric vestibular test (CVT) and the video head impulse test (vHIT) in the evaluation of Meniere's disease (MD) and to analyze their diagnostic accuracy.

MATERIALS AND METHODS:
Retrospective review of CVT and vHIT performed in MD patients at a tertiary care referral center in Spain.

RESULTS:
A total of 88 patients were reviewed. The CVT was abnormal in 67% (n = 59) of patients, while the vHIT was abnormal in 66% (n = 58) of them.

Agreement between both tests was poor, regardless of whether the horizontal semicircular canal (SCC) or all SCC were analyzed (kappa = .21). Anterior SCC pathology was found in 30% (n = 27) of the subjects while 51% (n = 45) had altered gains in the posterior SCC.

CONCLUSIONS:
Our study shows that patients with MD can have functional deficit involving the vertical semicircular canals, which cannot be detected by the CVT alone. Therefore, both tests should be used in a complementary fashion.
