Abstract

Meniere's disease is a poorly understood, disabling syndrome causing spells of vertigo, hearing fluctuation, tinnitus, and aural fullness. In this paper, we present a review of the histopathology, cytochemistry, and imaging of Meniere's disease. Histopathology is significant for neuroepithelial damage with hair cell loss, basement membrane thickening, and perivascular microvascular damage. Cytochemical alterations are significant for altered AQP4 and AQP6 expression in the supporting cell, and altered cochlin and mitochondrial protein expression. Current developments include imaging techniques to determine the degree and presence of endolymphatic hydrops, and future studies will endeavor to correlate the observance of hydrops with clinical findings.
