Abstract
In the present prospective study, we both investigated positioning techniques for the enhancement of oVEMP procedures and the viability of oVEMP testing in a healthy children population. A total of 41 healthy children were enrolled in this study. 21 were boys and 20 were girls, with their ages ranging from 4 to 16 years. All children underwent audiometry and tympanometry prior to oVEMP test in upright and supine position. All subjects had normal hearing. The procedure was well tolerated by all children. Typical biphasic oVEMPs presented in 97.56 % in upright position and 90.25 % in the supine position. No statistically significant difference could be found concerning which position elicits the best or worst responses. However, a trend towards the supine position was noticed. It may be concluded that oVEMP test proved to be a well-tolerated examination of the vestibular system in children aged above 4 years old. Our results did not show a statistical difference on the oVEMP thresholds between the two body positions. However, further larger studies are needed to confirm these findings.
