Could micro-marsupialization be an alternative treatment for Oral ranula? A case report and literature review

Oral ranula is a cystic lesion that arises in the floor of the mouth, and various treatment methods for it have been proposed. Micro-marsupialization is a relatively new method that is easy to perform and minimally invasive; however, its efficacy has not been examined enough. We report a 14-year-old patient with oral ranula extending beyond midline to the contralateral sublingual caruncle who underwent micro-marsupialization and obtained a good outcome without notable complications. We also discuss and analyze the relevant literature. Among 88 previously reported patients with oral ranula, the cure rate with micro-marsupialization exceeded 90 %. We believe that micro-marsupialization can become a standard treatment for oral ranula.
