outer hair cell

sensory cells in the organ of Corti in synaptic contact with sensory as well as efferent fibers of the auditory nerve; there are three rows of columnar outer hair cells largely surrounded by cortilymph and supporting phalangeal cells; the apical end of each cell is anchored to the cuticular plate and about 100 stereocilia arranged in a "V" pattern extend from the cell's surface through the cuticular plate into the tectorial membrane.
See also: cochlear hair cells, Corti cells.

Distortion-product otoacoustic emissions (DPOAE) are the sounds emitted by the outer hair cells of the cochlea in response to a pair of simultaneously presented pure-tone stimuli.

It has been emphasized that this effect is due to the temporary disorder in outer hair cells. Virks et al11 indicated that no loss of hearing or damage is caused by ESWL treatment, having conducted numerous studies on 30 patients.

The cellular basis for aminoglycoside hearing loss is a destruction of cochlear hair cells, specifically the outer hair cells. Aminoglycosides generate free radicals within the inner ear by activating inducible nitric oxide synthetase and therefore increasing nitric oxide concentrations.
Since OAE is not related to ion transport through the stria vascularis but associated with outer hair cell function, another explanation for the discrepancy between audiometric thresholds and DP-OAE results might involve damage to the ion transport system by RIT.
