[Selected issues related to the structure of the endolymphatic sac in Meniere's disease].

The morphometric examinations of the endolymphatic saccule epithelium in Ménière's disease were performed. The squamous epithelium prevailed in lower and cuboid and cylindrical in upper part of the saccule. In Ménière's disease the cellular nuclei are more elongated. The mean height of the epithelial cells are lower of 2,236 microns than the cells in normal hearing person. The morphometric method of examination permits to follow the supposition that in Ménière's disease there are the degeneration of the epithelial cells and subsequently the disturbances in endolymphatic resorption.
