CO2 laser in oral graft-versus-host disease: a pilot study

Abstract

This paper is the first to report the benefits of CO2 laser treatment for pain control in severe oral chronic graft-versus-host disease (GVHD). A CO2 laser device was used during 17 treatment sessions in four patients. The CO2 laser was applied over the mucosal lesions using 1 W for 2-3 s/1 mm(2). This treatment resulted in a consistent and significant decrease in pain, measured using a standard visual analogue scale. These results suggest that the CO2 laser can be used for the alleviation of pain in oral chronic GVHD.
