title: [Multifield local hyperthermia as a method for heating deeply located neck tissues].
abstract: Distribution of the thermal field in neck tissues in local SHF-hyperthermia is studied. The two-field method of irradiation permits a uniform heating of more deeply located layers of the tissue due to summation of the radiant energy. So, the contact method of irradiation using "Luch-2" and "Luch-3" sets permits elevating the temperature inside the larynx up to 41-41.5 degrees C and maintaining it under given conditions for 25-30 min, but the heat loading on the skin and subcutaneous fat remains high. When using noncontact irradiators and "Parus" set the deeply located neck tissues are heated to 42-43 degrees C, the temperature of surface layers not exceeding 41-42 degrees C. This temperature rate is possible to be maintained for 25 min; its prolongation induces a sharp rise in the temperature of surface layers. Long-term SHF-hyperthermia of deeply located neck tumours necessitates cooling of the integument surface.
