Neodymium-YAG and CO2 lasers in treatment of pre-cancerous lesions of the oral cavity.

The oral mucosa is an area of premalignant lesions such as leukoplakias and lichens. This work analyzes results obtained from patients who are carriers of these premalignant lesions treated with 1,060 and 1,320 nm Nd-YAG and CO2 lasers. Certain immediate and mediate post-op symptoms such as pain edema, hemorrhage, recidivism and scar fibrosis were studied and favorable results were obtained with this therapy.
