Absent Vestibular Evoked Myogenic Potentials in Vestibular Neurolabyrinthitis: An Indicator of Inferior Vestibular Nerve Involvement?

Abstract

These results suggest that if VEMPs are absent from an ear that has suffered acute VNL, then posterior semicircular canal BPPV is unlikely to develop as a consequence of the VNL. The reason for this appears to be that the absence of VEMPs is due to involvement of the inferior vestibular nerve or involvement of the structures that it innervates.
