Caloric Test, and Qualitative and Quantitative vHIT Analysis in Vestibular Schwannoma

Results highlight the importance of an accurate vHIT morphological analysis in the context of patients affected by VS. Indeed, given the relationship between vestibular deficit and number of compensatory saccades, our data further suggest that an increase in the generation of late compensatory saccadic events may reveal a vestibular deficit not adequately characterized by VOR gain analysis. A correct vestibular assessment must include the caloric test and the vHIT including both qualitative and quantitative analysis of the saccades in the presence of a normal VOR gain and normal symmetry.
