LASER PHOTOCOAGULATION FOR THE TREATMENT OF VASCULAR LESION IN OROFACIAL REGION
2020
A 53-year-old male patient presented with an approximately 8-year history of an asymptomatic "blood blister" on the lower lip. Extraoral examination revealed a soft, purplish, lobulated swelling on the left side of the lower lip skin. Intraoral examination showed a well-defined, purplish stain and papules on the left lower lip and alveolar mucosa, measuring approximately 1.5 × 1.0 cm. The diagnostic hypothesis was vascular lesion, which was later confirmed by a positive diascopy result. Under local anesthesia, the patient was submitted to 2 clinical sessions of photocoagulation with high-intensity diode laser (Thera Lase Surgery; 808∼830 nm ± 20 nm, 2.5 W, defocused 2 mm beam in continuous mode). The postoperative course was uneventful. After 6 months of follow-up, the patient reported only mild sensitivity in the region. Clinical examination revealed fibrosis compatible with the tissue repair process without aesthetic or functional impairment.
