The absence of a policy of adequate prevention transforms malignant lesions of the oral cavity, which are easily detectable in initial stage, in a pathology almost always diagnosed in an advanced evolutionary state. The exception in this case is the lip carcinoma, which proper characteristics are, in majority, diagnosed in initial stages. lnherent particularities to the surgical treatment, that is the choice therapeutics, makes that the most surgeons opt by the accomplishment of the surgery under general anesthesia. In the current study we propose to observe, by means of clinical evaluation, the benefit obtained when of the use of the CO2 laser radiation as a dieresis tool in the surgical therapeutics of this pathology when make in ambulatory room. We select 9 patients with squamous cell carcinoma in inferior lip, in the stadium T1N0M0 and 1 in the stadium T2N0M0 who were submitted for exeresis in ambulatory with use of the laser CO2 radiation, with power of 7 Watts (1 patient) and 5 Watts (9 patient). We conclude be the CO2 laser radiation, in the power dose of 5 Watts, is an extremely useful tool providing a clean surgical field, the determination of the safety margins (radicalit) in resection of the disease with extreme comfort and contributed with the oncological principle of centripecity when promoting the sealing of the blood and lymphatic vessels. The functional and aesthetic results observed in the patients submitted to the treatment went of excellent quality
