Histopathological evaluation in biopsies of palatine tonsils submitted to cryptolysis by coagulation with CO2 laser for treatment of chronic caseous tonsillitis.

Objective: To perform histopathological evaluation in biopsies of palatine tonsils in a group of patients, with symptoms of chronic caseous tonsillitis, treated with an innovative and conservative method, using CO(2) laser.

Background Data: In general, the treatment of chronic caseous tonsillitis with CO(2) laser, as described in the literature, refers to the clinical experience of the authors and, the technique used for criptolysis encourages tissue vaporization, which leads to the consequent reduction of the tonsillar parenchyma.

Materials And Methods: The individuals were submitted to cryptolysis coagulation with only 6 W of CW, CO(2) laser power, in scanned and unfocused mode, over a mean area of 2.
