KEY POINTS1.Our population represents a common clinical scenario in which auditory profiles do not determine eligibility for further evaluation.2.Mean VOR gain in the VS group, was significantly lower on the affected side in the three canal planes.3.Refixation saccades in the affected horizontal canal had a significantly higher latency and velocity in the VS group.4. When we categorized the presence of the VIN with mastoid stimulation, we yielded sensitivities of 81.8% and specificities of 73.9% for detecting VS.5.The VIN test causes minor discomfort with high diagnostic accuracy and should be considered before referring for further imaging.
