Vestibular Aqueduct and Endolymphatic Duct in Meniere's Disease

Abstract

Measurements were made of the widths of the vestibular aqueducts and endolymphatic ducts of nineteen ears with Meniere's disease and an equal number of controls. The data show that the vestibular aqueducts of ears with Meniere's disease are not different in caliber from those of normal ears. The endolymphatic ducts of ears with Meniere's disease, on the other hand, are smaller than those of the control group. It seems probable that this alteration is the result of Meniere's disease rather than the cause of Meniere's disease. The observation of Clemis and Valvassori of a higher incidence of nonvisualization of the vestibular aqueducts in ears with Meniere's disease is inconsistent with our data.
