The vestibular duct or scala vestibuli is a perilymph-filled cavity inside the cochlea of the inner ear that conducts sound vibrations to the cochlear duct.

It is separated from the cochlear duct by Reissner's membrane and extends from the vestibule of the ear to the helicotrema where it joins the tympanic duct.

When driven at sound pressure levels greater than ~110 dB stimulus pressure level, the mammalian middle ear is known to produce subharmonic distortion. In this study, we simultaneously measured subharmonics in the ear canal pressure, intracochlear pressure, and basilar membrane or round window memb

… In our previous reports we hypothesized that both vertigo and deafness in Meniere's disease could be explained by high potassium levels in the scala tympani, not in the scala vestibuli. … High potassium levels in the scala tympani may be caused mainly by the increased diffusion of potassium through the distended Reissner's membrane. …
