Objective: Vestibular Evoked Myogenic Potentials (VEMPs) are new tools for measuring vestibular function (saccule and inferior vestibular nerve). Many VEMP studies are conducted in adult group. By contrast, limited studies are designed for measuring response characteristics of children. Aim of this study was calculating VEMP data in this age group and comparing with adult group.
Methods and Materials: In this cross-sectional study, 19 normal hearing children aged 3-10 years (10 males, 9 females, and mean age 6.32 years) were enrolled. Children were requested to lie down on a bed and to contract their SCM in each side by bending their head 30 degrees up and rotate it toward opposite muscle. VEMP responses were recorded using 500 Hz tone bursts. p13 and n23 latencies, thresholds and amplitude ratios were calculated and compared with results from adults.
Results: Normal VEMP could be recorded in all subjects. Comparing latencies, thresholds and amplitude ratios showed no significant difference between children and adults.
Conclusion: VEMP testing could be used as a non-invasive and valuable tool for investigating vestibular function and specially vestibule-collic pathway in children.
