7] Schuknecht suggested that in DEH, the reabsorption of endolymph is compromised as a result of two possible consequences of the original insult: either damage to the endolymphatic sac or blockage of the vestibular aqueduct.
The stria vascularis secretes K+ into the cochlear endolymph and produces the endocochlear potential (9).
This model was based on the known physiology of the endolymph and the physical chemistry of aragonite, and was tested by Payan et al.
2) They proposed that BPPV is caused by the presence of free-floating debris in the endolymph of the semicircular canal.
6) Ten years later, an alternative explanation was offered by Hall et al, who proposed that in canalithiasis, degenerative debris does not adhere to the cupula but rather floats freely in the endolymph of the long arm of the canal.
5) In any event, impaired absorption or overproduction of endolymph is presumed to cause endolymphatic hydrops and associated Meniere's symptomatology.
One possible explanation is that the gentamicin affects the dark cells of the vestibular labyrinth and the secretory cells in the stria vascularis, which reduces the secretion of endolymph, thereby reducing endolymphatic hydrops.
Loop-diuretic-induced ototoxicity is marked by edema of the stria vascularis and changes in ionic potentials in the endolymph and perilymph.
