Inner Ear Vasculature in Experimental Hydrops

Abstract

We experimentally produced hydrops in guinea pigs by silver nitrate injection method. Some of them so treated were then exposed to sound for 2 hrs (1KHz, 120, dB). And there were circularly disturbance in their cochleas, especially stria vascularis. In the cochleas of these guinea pigs after glycerol administration, there were no findings of local circulatory disturbance. We suggested glycerol effect improved local circulation in the cochlea.
