Histological, Thermal and Biochemical Effects of Ultrasound on the Labyrinth and Temporal Bone

AbstractThe action of 3 megacycle ultrasonics on the labyrinth of guinea pigs and sheep is described. Temperature measurements in different parts of the labyrinth during ultrasonic application are reported. Histological and biochemical effects are presented, showing characteristic changes in the fluids and in the vestibular and cochlear end organs.
