메니에르병 증상을 동반한 이경화증 1예

Abstract

It has been postulated that otosclerosis may produce vertigo by several mechanisms. An association between otosclerosis and Meniere’s disease has been proposed on both a clinical and histopathologic basis but the causal relationship is controversial. We report a case of bilateral otosclerosis in a man manifesting vertiginous symptoms. Fifty one year-old man was examined for rotational vertigo and poor hearing in his both ear for ten years. The audiogram revealed left sided hearing loss of a conductive type and right sided sensorineural hearing loss, and caloric asymmetry. Meniere’s disease was suspected, but temporal bone CT showed low attenuated lesion around bilateral cochlear and semicircular canal. A diagnosis of otosclerosis was made. He was recommended sodium fluoride therapy. Severe endolymphatic hydrops manifesting itself as Meniere’s disease can be the result of otosclerosis, so vertiginous and concurrent hearing symptoms should not be overlooked
