| ABSTRACT |
Background and Objectives: The aims of this study were to measure otolith function using subjective visual vertical (SVV) test and vestibular evoked myogenic potential (VEMP) test in patients with unilateral Meniere’s disease, and to see the relationship of the otolithic impairment with caloric and audiologic results.
Materials and Methods: Twenty two patients with unilateral Meniere’s disease who received treatment and also had been tested for pure tone, caloric, SVV and VEMP tests were enrolled. All the tests were done simultaneously.
Results: Five of 22 (23%) patients showed abnormal tilt to the lesion side in SVV test, and 13 of 22 (59%) patients showed abnormal VEMP results on the affected side. There was no correlation between SVV tilts and unilateral weakness (UW) in caloric tests or pure-tone average. There was also no difference of UW in patients with or without VEMP abnormalities. Two patients showed abnormal finding in both SVV & VEMP tests. One patient showed UW (47%) and SVV tilt (3.08°) to the lesion side, and the other showed normal UW and SVV tilt (3.22°) to the lesion side.
Conclusion: Our results demonstrate that the otolith system was implicated in 16 out of 22 (73%) patients with Meniere’s disease. However, there was no correlation between the abnormal results of the three tests and these findings suggest that impairment of the otolithic function is depending on the extent and/or the localization of Meniere’s disease, suggesting vestibular rehabilitation for the specific lesion might be helpful.
