Endolymphatic hydrops induced by noise exposure.
In animal with cochlear deafness induced by firecracker explosion, fibrous degeneration of the endolymphatic sac was observed 4 months after the disappearance of Preyer's reflex. Endolymphatic hydrops induced by noise exposure may develop as the results of degeneration of the endolymphatic sac due to cochlear deafness by acoustic trauma after the lapse of a long period of time.
