Dysfunction of the ES is considered to induce excess of endolymph, leading to endolymphatic hydrops typically observed as bulging of the Reissner's membrane in the cochlea, and causes vertigo and hearing loss [3].
Moreover, other structures (e.g., tectorial membrane and Reissner's membrane) in the cochlea have also been suggested to be capable of supporting wave propagation inside the cochlea [21, 22], but their contribution to the cochlear mechanical dynamics has not been thoroughly studied and determined.
The greater impact that air in the scala vestibuli had on hearing might have been the result of a collapse of Reissner's membrane. Kobayashi et al concluded that pneumolabyrinth involving the oval window might be more severe and perhaps cause irreversible hearing loss.
