Abstract
Twelve years' experience of ultrasound treatment of 356 patients is presented. For evaluating the results a new multifacetted scoring system was developed, where each individual patient was evaluated on the basis of four parameters. According to this evaluation 71% of the patients improved after the operation, while 29% remained unchanged or deteriorated. Because of lack of improvement, 42 patients underwent reoperation by different methods; in half of them ultrasonic irradiation was again used. The hearing deteriorated in about 40% of the patients, to which result the long observation times also contributed. The caloric response became reduced in 70% of the patients. Marked depression of the caloric response characterized the patients who were relieved of vertigo. Transient facial paralysis in 4 patients was the only complication.
