Ultrasonic irradiation of the inner ear applied through the round window is used as treatment of Meniere's Disease, Kossoff et al (1967, 1968), Basek (1970). The aim of this project was to study histological changes that occur in the inner ear of sheep following an ultrasonic irradiation. The ultrasonic generator and round window applicator used were those designed by the Commonwealth Acoustic Laboratory and which are currently commercially available. The 1.5 mm transducer operates at 3.5 MHz and has an output of up to 100 milliwatts. In this study the inner ears of three sheep were irradiated at intensities ranging from 40-100 milliwatts for a duration of 20 minutes. This is a typical dose used for human treatment.
