Abstract

We induced experimental hydrops in guinea pigs after cauterizing the sac with silver nitrate and observed their inner ear vessels by scanning electron microscope using the casting method. Abnormal morphological changes were seen in the microvascular system of the cochlear lateral wall and the saccular macula on hydrops side, suggesting a circulatory disturbance in the inner ear.
