Changes in cochlear function during acute endolymphatic hydrops development in guinea pigs

► A physiologic model of the effects of endolymphatic hydrops on cochlear function. ► Periods of functional recovery in the cochlea during endolymphatic injections. ► During hydrops development, scala media volume increase is a discontinuous process. ► Slow injections of artificial endolymph into scala media. ► X-ray micro CT images of hydropic cochlea.
