its influence increases the permeability of the skin, blood vessels, cell membranes due to mechanical loosening of connective tissue and depolymerization of hyaluronic acid (assuming that the molecular weight of hyaluronic acid decreased from 10 in the seventh degree to 10 in the fifth degree Dalton - 2 orders of magnitude). In addition, the inside of the cells formed microflows, resulting in the transfer of intracellular stasctures and to expose the enzymatic centers.

These changes dramatically increase the functional activity of cells and their sensitivity to physical and chemical (eg, pharmacological) effects. Therefore, the therapeutic effect of ultrasound and dasg magnified due to the addition of their actions.

Technique for treatment of chronic tonsillitis using low-frequency ultrasound phonophoresis developed Department of ENT diseases OGMI.
The essence of the method is the direct impact of energy low-frequency ultrasonic vibrations on the palatine tonsils through various contact media (solutions of antiseptics and medicines).

Technical parameters of treatment to a large extent depend on the available equipment. Department of ENT diseases OGMI recommend the following:

The oscillation frequency of the tool ~ 26.5 kHz - a resonant frequency of the device URSK-7.

The amplitude of oscillation of this device 10-60 microns, depending on the extent to which the resonance. For phonophoresis amplitude must be at least 40 microns. The yield-valued output of the device is ~ 160 watts.

Equally important is the value of vacuum created by suction. Department recommended negative pressure 0,2-0,4 bar. The increase in dilution, while reducing the exposure time is doubtful because of increasing probability of injury tonsils. For example, at a negative pressure of 2 atm. and standard sizes of applicator force acting on the amygdala, is 4-5 kg.
