The purpose of this study was to analyze the effectiveness of Nd: YAG laser photocoagulation in the treatment of vascular malformations in the oral and perioral area; 93 patients (104 lesions) were evaluated in an Ambulatory of Oral Medicine (2006–2013). The sample consisted of 57 women (61%) and 36 men (39%), aged 8 to 85 years. The lesion size was smaller than 3 cm in most patients. The lesions were located on the lips, jugal mucosa, tongue, palate, gingiva, and retromolar trigone. All patients were treated on an outpatient basis using local anesthesia and Nd: YAG laser (Power Laser C ) with a wavelength of 1064 nm and a fiber optic diameter of 400 μm. After treatment no patients had complications, however, in patients of deep lesions, 2 or more irradiations were required to treat the lesions. Finally, the authors conclude that the clinical and aesthetic satisfactory results of the 93 patients treated with Nd: YAG laser suggest that this type of laser is effective and safe in the treatment of oral and perioral vascular malformations.
