Objective: The current study pretends to present a clinical case of aesthetic and functional rehabilitation of a lower lip that was deformed due to vascular lesion. Treatment was executed by using a surgical diode laser and both primary healing time and postoperative pain were being constantly macroscopically evaluated. Case description: 12 year old patient with vascular malformation. The lesion was located in all right side of the lower lip from internal face to midline, and it was compromising both esthetics and function. Lesion measurement was 25x20x10mm going through the internal face of the lower lip having 25x12mm in its wider area. Surgical treatment was made in 2 sessions of 980nm surgical diode laser (GaAl) along with fiber tips of Ø 400µm. Patient's pain degree was constantly examined in the first 3 days after the sessions. The patient had regular clinical follow ups in a 6 months period. Results: The results displayed a total re-epithelialization in about 21 days. Patient had no serious complications and postoperative pain was minimal and occurred only in the first 2 days. The patient displayed excellent aesthetical results having an almost indistinguishable scar after 6 months. Conclusions: The use diode laser can be considered as an ideal solution for treatment of vascular anomalies located in oral cavity. Keywords: vaskular tumor, oral surgery, diode laser
