The present study was undertaken to assess the sensitivity of vestibular evoked myogenic potentials testing to side-of-disease in Ménière's disease patients and to test the hypothesis that information supplied by vestibular evoked myogenic potentials is complementary to that provided by a conventional vestibular test battery. Study Design: Prospective cohort study. Setting: Large specialty hospital, department of otolaryngology. Subjects: Twenty consenting adults (9 men and 11 women) with unilateral Ménière's disease by American Academy of Otolaryngology-Head and Neck Surgery diagnostic criteria. Interventions: All subjects underwent bilateral vestibular evoked myogenic potentials testing using ipsilateral broadband click and short-toneburst stimuli at 250, 500, and 1,000 Hz. All subjects also underwent electronystagmography and sinusoidal vertical axis rotation testing. Main Outcome Measures: Accuracy of side-of-disease assignment by vestibular evoked myogenic potentials, caloric asymmetry, and multivariate analysis. Results: Side-of-disease assignment was most accurate using caloric asymmetry with a 5% interaural difference criterion, achieving 85% correct assignment. The next best method was

Our goal was to find the clinical value of cervical vestibular evoked myogenic potential (VEMP) in Ménière's disease (MD) and to evaluate whether the VEMP results can be useful in assessing the stage of MD. Furthermore, we tried to evaluate the clinical effectiveness of VEMP in predicting hearing outcomes. The amplitude, peak latency and interaural amplitude difference (IAD) ratio were obtained using cervical VEMP. The VEMP results of MD were compared with those of normal subjects, and the MD stages were compared with the IAD ratio. Finally, the hearing changes were analyzed according to their VEMP results. In clinically definite unilateral MD (n=41), the prevalence of cervical VEMP abnormality in the IAD ratio was 34.1%. When compared with normal subjects (n=33), the VEMP profile of MD patients showed a low amplitude and a similar latency. The mean IAD ratio in MD was 23%, which was significantly different from that of normal subjects (P=0.01). As the stage increased, the IAD r...
Usefulness of vestibular evoked myogenic potentials in diagnosis of peripheral vestibular disorders
International Journal of Otorhinolaryngology and Head and Neck Surgery
Background: Vestibular evoked myogenic potentials (VEMP) are electromyographic responses to high-intensity acoustic stimuli to test vestibular system, otolith function and integrity of inferior vestibular nerve. These are easy to perform and non-invasive. In this study, we aimed at clinical application of VEMP to evaluate common peripheral vestibular disorders.Methods: Prospective observational study carried in ENT department during January 2015-November 2016 over 40 patients in age group between 30-70 years with history of vertigo who underwent regular neuro-otological examination and VEMP.Results: Of these, 25 diagnosed with BPPV, 11 with Meniere’s disease, and four with vestibular neuritis. Eight patients showed delayed VEMP responses. 28 (70%) patients had normal VEMP, 12 (30%) had abnormal VEMP responses. Out of 25 patients suffering from benign paroxysmal positional vertigo (BPPV) posterior semi-circular canal was involved in 20 (80%) patients and lateral semi-circular canal i...
Utility of Vestibular Evoked Myogenic Potentials in the Diagnosis of Meniere’s Disease: A Review
Journal of Hearing Science, 2013
Meniere’s disease is an inner ear disorder characterized by aural fullness, spontaneous attacks of vertigo, fluctuating low-frequency sensorineural hearing loss and tinnitus. There are various tests such as puretone audiometry, electrocochleography, glycerol test, Caloric test, Cochlear hydrops analysis masking which have been utilised in diagnosing the Meniere’s disease. Recently cervical vestibular evoked myogenic potentials and ocular vestibular myogenic potentials have been utilised to measure the functioning of the sacculocollic and otolith ocular pathway respectively. The objective of the present study is to provide an overview of the cervical and ocular vestibular evoked myogenic potentials tests findings in individuals with Meniere’s disease.
Role of cervical vestibular evoked myogenic potential response in identifying vestibular dysfunction
The Journal of Laryngology & Otology, 2013
Objectives:To analyse cervical vestibular evoked myogenic potential response parameters in normal volunteers and vertiginous patients.Subjects and methods:A prospective study of 50 normal subjects and 50 patients with vertigo was conducted at Chiang Mai University Hospital, Thailand. Cervical vestibular evoked myogenic potential responses were measured using air-conducted, 500-Hz, tone-burst stimuli with subjects in a sitting position with their head turned toward the contralateral shoulder.Results:The mean ± standard deviation age and male:female ratio in the normal (44.0 ± 9.3 years; 12:38) and vertigo groups (44.7 ± 9.8 years; 17:33) were not significantly different. The prevalence of absent responses in the normal (14 per cent) and vertigo ears (46 per cent) differed significantly (p < 0.0001). Other cervical vestibular evoked myogenic potential parameters (i.e. response threshold, P1 and N1 latency, P1–N1 interlatency and interamplitude, inter-ear difference in P1 threshold,...
The Follow-Up Role of the Vestibular Evoked Myogenic Potential Test in Meniere's Disease
Acta medica Iranica, 2018
Despite some proposed roles for the diagnostic impact of the cervical vestibular evoked myogenic potential test in the patients with Meniere's disease, the role of this test as an objective instrument in following up the patients with Meniere's disease who underwent. Intratympanic steroid injection is not cleared. In a prospective study, thirty-one adult patients with definite one-sided Meniere's disease with vertigo as main complaint refractory to medical treatments for three months, were selected. Patients underwent three times of intratympanic dexamethasone injection with one-week intervals. We performed cervical vestibular evoked myogenic potential test at first and four weeks after the last injection for all participants. We followed the patients for one year. The study results were analyzed with the chi-square test. Cervical vestibular evoked myogenic potential test could not be recorded in 26 patients (83.9%), and the test results were abnormal in the remaining 5 ...
Applications of vestibular-evoked myogenic potentials in vestibulogy. 1. Basic principles
2020
Diagnosis of vestibular disorders represents a serious challenge for modern otoneurology. In the recent decades, there is a gradual enrichment of the diagnostic tools enabling the objective assessment of the physiology of the vestibular system under normal and pathological conditions. Here belong the vestibular-evoked myogenic potentials (VEMPs). In the first of a series of review papers on this hot topic, the basic peculiarities of both types of the VEMPs, the cervical and ocular VEMPs, are summarized.
The clinical reliability of vestibular evoked myogenic potentials
Ear, nose, & throat journal, 2010
Vestibular evoked myogenic potential (VEMP) testing has gained popularity as a diagnostic modality in otolaryngology and audiology. To maximize the utility of this test, examiners need the availability of ideal test settings and reliable norms. We conducted a prospective study of 8 subjects with no history of neurotologic symptoms to examine the test-retest consistency of VEMP testing and to analyze the impact of stimulus type and muscle tension monitoring. All subjects underwent VEMP testing with two stimuli: a 500-Hz tone and a click. With each stimulus, testing was completed with and without monitoring of sternocleidomastoid muscle tension. All subjects participated in an initial testing session and then returned for a repeat testing session 2 to 4 weeks later. We measured the amplitude of primary waveforms P13 (first positive peak) and N23 (first negative peak) and analyzed the reliability and reproducibility of the mean amplitude asymmetry of these VEMP peaks. The P13 component...
Objective: Frequency amplitude ratio (FAR) is one among several parameters of cervical vestibular evoked myogenic potential (cVEMP) found useful in diagnosis of Meniere’s disease. This being the least explored of the parameters, there is not only a need for further investigation but also a need for identifying the best suited frequency amplitude ratio for diagnosing Meniere’s disease. Design: This prospective study aimed at investigating FAR of cVEMP in healthy individuals and individuals with Meniere’s disease establishing the optimum frequency pair for assessment of Meniere’s disease. Study sample: Twenty two individuals with unilateral definite Meniere’s disease were compared against 22 healthy individuals. Results: Frequency amplitude ratios corresponding to 750/500, 1000/500, 1500/500 and tuned frequency/500 were all found useful in diagnosis of Meniere’s disease by virtue of showing larger frequency amplitude ratio in Meniere’s disease ears compared to the controls (p< 0.05...
