KEY POINTS
1.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.
