Correlation of Endolymphatic Hydrops and Perilymphatic Enhancement with Clinical Features of Ménière’s Disease

To investigate the correlation of the EH grade and PE with clinical features in MD, we evaluated their correlations by using the cubic spline models and multivariate analysis. We found that a nonlinear or linear correlation of EH grade and SIR with duration of disease-related symptoms and hearing thresholds. Additionally, the higher duration of vertigo and LFHT were associated with a higher EH grade, as well as duration of tinnitus and vestibular EH for SIR. Consequently, the grades of EH and the extent of PE in patients with MD can be evaluated by use of some clinical features and PTA.
