Abstract

Spatial and temporal coherence are properties of laser light we studied for some time as responsible for biophysical phenomena, capable of significant contributions in the treatment of chronic inflammatory lesions. In this paper we present the results of five years experience in the application of CO₂ low power laser (LPL) therapy as a new means of treating chronic pharyngitis. Based on our previous studies, we selected 85 patients with nonspecific chronic pharyngitis to be treated at our laser unit. The patients were grouped as follows: Group I, 40 patients, predominance of hyperemic aspect; and Group II, 45 patients, predominance of hypertrophied aspect. Both groups were submitted to low power irradiation of CO₂ laser in eight to ten sessions, one week interval according to the evolution of symptoms. The good results obtained lead us to conclude that this new application for LPL is very suitable for systematic treatment of chronic pharyngitis: a very common and disturbing symptom for a great number of ear, nose, and throat patients, still lacking an effective form of therapy.
