STANDARDIZATION OF CERVICAL VESTIBULAR EVOKED MYOGENIC POTENTIAL TESTS WITH AIR AND BONE CONDUCTION STIMULATION IN HEALTHY ADULTS
1Cumhuriyet Üniversitesi, KBB, Sivas, Turkey Objective: The aim of this study was to obtain normative data on Cervical Vestibular Evoked Myogenic Potentials (cVEMP) test in adult age group to use as a differential diagnostic test in our clinic.Materials and Methods: This prospective study was conducted on 50 volunteers who were completely healthy, had no history of vestibular disorder and hearing loss, and had normal otoscopic and audiologic examination results at the Department of Ear-Nose-Throat. The p13 and n23 latency, p13-n23 interpeak latency and p13-n23 amplitude values of both ears of the subjects in the study were analyzed.
Results: In the examination of mean values of cVEMP with air and bone conduction sound stimulation according to the genders, there was a statistically significant difference in the comparison of air conduction p13 latency, n23 latency and p13-n23 amplitude and bone conduction p13 latency (p <0.05).
The air and bone conduction cVEMP test according to age groups was evaluated; a statistically significant difference was calculated according to the age groups in p13-n23 interpeak latency air conduction measurement and p13 and n23 latency bone conduction measurement values (p <0.05).
Conclusion: In addition to the determination of normative values of our clinic in this study, we hope to make a contribution to the studies conducted on this matter in the literature through the results of the present study. Additionally, limit values of cVEMP test parameters assessed in the present study were also calculated. Determination of these values would be able to enable to form our standards to establish differential diagnosis of various diseases in the future.
