A Comparison of cVEMP and VNG Examination Results Between Adults and Children with a History of Vertigo.

Dizziness and vertigo are common symptoms. Vertigo, caused by vestibular deficit, is usually diagnosed with videonystagmography (VNG) and cervical vestibular evoked myogenic potential (cVEMP). Normative values of these examinations have been established for adults; however, the impact of age is still uncertain. This study aimed to compare the results of VNG and cVEMP between adults and children. We analyzed and compared the results of VNG and cVEMP in 119 patients (35 adults and 84 children.) Statistically significant differences were observed between adults and children in the amplitude of the cVEMP examination. In the subgroup analysis by age, we also noticed differences in VNG examination in nystagmus induced by rotation in patients with peripheral vertigo and in IFO (index fixation test) and VOR (vestibulo-ocular reflex) in patients with non-peripheral vertigo. This study confirms that there are differences in vestibular examination results between children and adults. However, the exact impact of age on each part of the vestibular examination requires further investigation.
