Abstract
We report a patient with Lermoyez's syndrome who was followed up for 9 years and whose hearing activity was well maintained. The main pathological factor in this case was considered to be endolymphatic hydrops, judging from such findings as positive glycerol test, repeated vertigo attacks like Meniere disease and well-maintained hearing activity under Isosorbide therapy. Since Dilazep dihydrochloride was also effective in preserving good hearing function, disturbance of vascular circulation might have played a role in the pathology of this case.
