Surgical treatment of ranula with carbon dioxide laser radiation.

Ranula is a mucous extravasation cyst which appears as a swelling in the submental and submandibular regions. Several surgical techniques to manage ranula have been described in the literature, these techniques include the CO2 laser radiation excision. Four patients were treated for intraoral ranula in the floor of the mouth by marsupialization with carbon dioxide laser radiation with defocused beam, continuous mode and 4 watts of power. There were no complications and no recurrences have occurred to date. The results showed that carbon dioxide laser radiation gives optimal results with no need for suture and good wound healing.
