What is the recommended treatment for a recurrent ranula?

The recommended treatment for a recurrent ranula is excision of the sublingual gland. This approach addresses the underlying problem of fluid accumulation and mucous retention associated with the ranula. A ranula forms when there is obstruction or damage to the sublingual gland or its ducts, leading to the buildup of saliva.

By excising the sublingual gland, the source of the ranula is removed, which significantly decreases the likelihood of recurrence. This definitive surgical intervention not only removes the existing ranula but also prevents the formation of new ranulas by addressing the gland's dysfunction. In cases of a ranula, especially recurrent ones, conservative treatments such as medical management or observation are not effective long-term solutions, as they do not resolve the underlying cause.

Incision and drainage may help relieve symptoms temporarily but does not prevent recurrence since it does not address the gland itself or its function. Thus, excision of the sublingual gland is considered the most effective and recommended treatment for managing recurrent ranulas.
