Objective: To evaluate the EH on both sides in patients with unilateral and bilateral MD, and to investigate factors with progression to bilateral MD including the degree of EH, hearing level, and the duration of MD.
Conclusion: All definite Meniere’s disease (MD) had endolymphatic hydrops (EH) at least in the cochlea or the vestibule. Symptoms of MD may appear after formation of EH. It is assumed that the probability of immediate progression to bilateral MD from unilateral MD is very low in patients without EH on the non-affected side.
