This study demonstrated that biologically active points (BAP) of external ear were sensitive to ultrasonic treatment. In order to identify their characteristics, specific conductivity of tissues in the BAP area was measured (in microamperes) by an Elita 4-PEP unit equipped with a silver probe. Conductivity was measured in five points. Such points as i-feng, er-meng, nei-er were shown to influence the cochleovestibular system and exhibit conductivity of approximately 150 microA. The risk of point hyperactivity increased drastically by the 4th and 13th exposure in response to unilateral endaural pharmacophysical treatment with 0.4 W/cm2 ultrasound. The use of ultrasound of lower intensity (0.05-0.2 W/cm2) helped to avoid this complication. These observations suggest that phonopuncture can constitute a component of endaural pharmacophysical treatment of internal ear.
