Abstract

BACKGROUND AND OBJECTIVES: Otitis media with effusion (OME) is one of the most common diseases in children and may be frequently related with dizziness. However, the association between OME and dizziness seems to be not clear and remains controversy. The purpose of this study was to determine the incidence of dizziness in children with long lasting OME, and to investigate the difference in vestibular functions between children with long lasting OME and the control group. MATERIALS AND METHOD: Thirty one children who had long-lasting OME over than 6 months (study group) and 28 normal hearing children without OME who were scheduled for adenotonsillectomy (control group), were given questionnaires and vestibular function tests (VFT) including electronystagmography (ENG) and rotation chair test (RCT). Statistical analysis was performed with chi-square test.
RESULTS
Dizziness was found in 7 (22.6%) of 31 children in the study group and 2 (7.1%) of 28 children in the control group (p>0.05). The difference of abnormal findings in VFT between the study group and the control was not significant except visual vestibulo-ocular reflex (VVOR) in RCT. Most of the correlations in the study group, bilateral vs. unilateral OME, OME with dizziness vs. OME without dizziness, and preoperative vs. postoperative, were not significant.
CONCLUSION
We did not find any evidences of significant difference of the incidence of dizziness and findings of VFT between children with long lasting OME and children without OME. However, there was a significant abnormal response in VVOR in RCT in children with long-lasting OME, suggesting the children with OME may be more dependent on the nonvestibular system including visual compensation to maintain balance.
