Introduction: Conventional cryptolysis with CO2 laser has been performed with success and in this case, a considerable volume of tissue is removed without warring about possible reduction of the immunological function of the tonsils. In the present paper we propose an alternative cryptolysis method with CO2 laser for chronic causeous tonsillitis. In this way, the desired effect is obtained by coagulation with laser and not by the volatilization of the tissues. The preservation of tissues is optimized. Method of study: Clinical prospective. Objectives: To present a modified cryptolysis technique with CO2 laser, which inhibits the retention of the caseous and preserves the tonsilar parenchyma. Material and Method: The cryptolysis were performed on a group of thirty-one individuals with chronic causeous tonsillitis, with great elimination of caseous and other associated symptoms. The patients were selected from the ORL HC-UNICAMP ambulatory. We used 6W CO2 laser in continuous mode, unfocused, and Swiftlase around the opening of the crypts, and, afterwards over the entire tonsilar surface producing only a superficial coagulation. To eradicate the symptoms we performed on average seven applications, repeated every three weeks. Results: The proposed technique was effective in 87% of the cases. For the remaining 13%, it was also necessary to volatize the regions adjacent to the crypts. There was a two-year follow-up without evidence of complications. Conclusion: We conclude this to be a safe and efficient method, able to be performed in the ambulatory under topic anesthesia; therefore, permitting to the patients immediate return to their activities.
