Masseteric Vestibular Evoked Myogenic Potentials in Vestibular Neuritis: A Case Series.

Introduction: Masseteric VEMPs have been effective in evaluating a diverse spectrum of vestibular conditions associated with various brainstem pathologies, but they have rarely been explored among patients with vestibular neuritis.

Case report: The current investigation included a case series highlighting mVEMP responses in addition to cVEMPs and oVEMPs in three patients diagnosed with vestibular neuritis. In the study, all three patients were found to have absent or diminished responses in cVEMPs, oVEMPs, and mVEMPs.

Conclusions: In the present study, the distinctions in cVEMP and oVEMP findings can be attributed to the involvement of inferior and superior vestibular nerve respectively. Furthermore, mVEMP presents a more intricate scenario, both in terms of its genesis and outcomes. This emphasizes the clinical relevance of mVEMP when used in combination with cVEMP and oVEMP, rather than as a substitute for the other VEMPs.
