Abstract

Background and Aim: Vestibular evoked myogenic potentials [VEMP] are electromyographic responses to acoustic stimuli to assess the otolith function and integrity of inferior vestibular nerve. It is an easy test to perform and non-invasive. This study was designed to study and compare AC and BC cVEMPs in patients with vestibular neuritis.  
Patients and methods: This observational case control study was conducted on 40 subjects in the age range of 20-60 years selected from Audio vestibular clinic of Al Zahraa university hospital. Twenty patients diagnosed with Vestibular neuritis according to a standard clinical criterion, and the other twenty subjects were normal healthy subjects with no complaint of dizziness or history of vestibular disorders
Results: In this work, about 25% of study group had abnormal AC cVEMPs while 35.0% had abnormal BC cVEMPs.
Conclusion: Both AC and BC evoked cVEMPs should be considered as complementary test along with other conventional vestibular function tests in patients with vestibular neuritis.
