Abstract

For reduction of a zone of a thermal damage limphoid tissue and certain influence on the changed wall of a lacuna cryolaser segment lacunotomy with use Nd:YAG laser is offered at chronic tonsillitis. The tip of the lighttube of a type side-focus was entered into a gleam of a lacuna. The tip was cooled by a line method of pairs nitrogen. Parameters of radiation length of a wave 1.32 microns, capacity -25 Wt, exposition -3 sec. The comparative analysis 90 histologic tissue specimens of palatal tonsils with pathological change of lacunas is carried out. The influence ona segment of lacuna up to 90 degrees, allows to expand a gleam of lacuna, by keeping thus lymphoepithelial barrier of an opposite wall. The zone of the necrobiotical changes and infiltration of a lymphoid tissue on preparations undergone to laser influence with cooling average in 2 times is less, than at application of laser influence. The operation was spent to 50 patients chronic tonsillitis.
