Plantar warts present a challenging therapeutic problem. In 1958, Kent1 reported successful therapy of these warts with the use of ultrasound waves. The following report covers our observation of 25 patients treated with ultrasound therapy. The patients were all seen by a dermatologist before therapy was instituted, and calluses were carefully excluded.
The Burdick UT-1 Ultrasonic Therapy Unit was used. It has a frequency of 870 kcps. The transducer is able to deliver a total energy of 21 watts. The crystal is designed to deliver an effec tive energy of 0.1 to 3 watts per square centimeter. The meter shows the exact total wattage delivered but not that received. A dosage timer automatically cuts off power to the transducer when the treatment period is completed.An extra heavy liquid petrolatum (mineral oil) was used as a coupling agent to insure contact of the soundhead with all areas
