MICROMARSUPIALIZATION AS A CONSERVATIVE TREATMENT FOR RANULA

An 11-year-old female patient complained of "a blister in the mouth." Intraoral examination evidenced a bullous lesion in the left mouth floor measuring approximately 4 cm with exophytic growing, bluish coloration, defined limits, soft consistency, smooth surface, and 5 days of evolution. Clinical diagnosis was ranula. Micromarsupialization was performed after infiltrative anesthesia, and surgical knots were made far from the mucosa by the interposition of a hemostatic clamp, forming fistulas originating from the epithelization around the thread, allowing salivary flow. In the transoperative period, there was immediate drainage of part of the content retained within the lesion, reducing its initial volume. Surgical knots were removed after 7 days, and the patient was followed up for 3 months. The lesion regressed entirely without signals of recurrence, ruling out the need of excision. Therefore, micromarsupialization stands as a conservative therapy for the treatment of ranulas and mucoceles of significant size.
