Introdution: Leukoplakia is defined as a white plaque of a questionable risk having excluded known diseases or disorders that carry no increased risk for cancer. Laser therapy has been a favoured treatment regime for oral leukoplakia since the mid 1980“s. Aim: To analyze the effectiveness of the CO2 Laser (10600nm) vaporization in treatment of a series of ten cases of oral leukoplakia. Description evolution: Of the ten cases, six were men and 4 women. Mean age of the patients was 55.4 years-old (range 35-76). Lesions range in size 1cm to 7cm and were located in gingival mucosa in 4 cases, buccal mucosa in 3 and tongue in 3. There were 6 homogeneous and 4 non-homogeneous type leukoplakias. Every lesion was previously biopsied and the leukoplakia diagnosis was confirmed in all. For each vaporization procedure we use carbon dioxide laser (DEKA Smart US 20D) with angulated mirror hand piece, defocalized and continues mode, 5W power, 2 mm spot, PD of 159.2W/cm2 and fluence of 159.2 J/cm2. There were no complications during surgery. Complete healing was achieved in a period of 3 weeks (mean 20.3 days ±2.2). The patients were followed at least 12 months (mean follow-up period of 25 months) and any signs of recurrence were noted. Primary complete elimination of the lesions was achieved for all cases. There were two recurrences (20%) in a period of 3 and 6 months. Discussion: Our experience confirms that CO2 laser is a safe and efficient method to eliminate oral leukoplakia.
