# Vestibular Evoked Myogenic Potentials to Diagnose Vestibular Neuritis: A Scoping Review

## TL;DR

This review examines how Vestibular Evoked Myogenic Potentials (VEMPs) can help diagnose Vestibular Neuritis by identifying which part of the vestibular nerve is affected.

## Contribution

The study highlights the differential diagnostic value of ocular and cervical VEMPs in Vestibular Neuritis and emphasizes the need for standardized protocols.

## Key findings

- VEMPs provide valuable diagnostic information for identifying the affected vestibular nerve branch in Vestibular Neuritis.
- Combining VEMPs with other vestibular tests improves diagnostic accuracy.
- Methodological differences across studies limit direct comparisons but highlight the need for protocol standardization.

## Abstract

This scoping review aims to explore the diagnostic value of Vestibular Evoked Myogenic Potentials (VEMPs) in people with Vestibular Neuritis (VN) with a specific focus on the differential contribution of ocular (oVEMPs) and cervical (cVEMPs) recordings.

A comprehensive search was conducted in December 2024 across PubMed, Scopus, and the Cochrane Library. Studies published in English and involving adult patients with suspected or confirmed VN and assessing VEMPs were considered eligible.

The PRISMA‐ScR guidelines were followed. Data were extracted regarding methodology, patient characteristics, and diagnostic performance of VEMPs.

Eighteen studies met all eligibility criteria. Included studies consistently demonstrated that VEMPs offer valuable diagnostic information in VN, particularly in identifying the affected branch of the vestibular nerve. Several studies supported the use of VEMPs in combination with other vestibular tests to enhance diagnostic accuracy. Methodological heterogeneity in stimulation parameters and recording techniques limits direct comparison across studies but underscores the need for protocol standardization.

VEMPs are a useful adjunctive tool in the diagnosis of VN, particularly for topographic localization of vestibular nerve involvement. Future research should focus on standardizing protocols and exploring correlations with clinical outcomes to refine their diagnostic utility further.

Standardization of stimulation and recording protocols is essential to improve comparability across VEMP studies. Integrating cervical and ocular VEMPs with other vestibular tests enhances diagnostic accuracy and supports precise localization of vestibular neuritis.
