The objective of the present work was to evaluate the morphofunctional state of the polypous tissue under conditions of radiofrequency-wave (from 15 to 40 W) and laser interstitial (from 1 to 10 W) thermal therapy. It was shown that both techniques exerted no influence on the structure and physiology of epithelial glands, regardless of the regime chosen for their application. The therapeutic effect was achieved due to the influence of radiation on the loose connective tissue leading to the modification of its structure and the reduction of the volume of the polypous tissue. Laser interstitial thermal therapy at 3-7 W was found to be the most efficacious and injurious regime. In contrast, laser radiation over 7 W and radiofrequency-wave treatment (15-40 W) proved the most traumatic regimes. They cause coagulation and tissue necrosis at the sites of their direct application; these effects were strongly dependent on the radiation power.
