Sublingual ranula: report of a submandibular clinical case

Ranula is a raised mucocele on the oral floor. When the mucocele extends and passes the sublingual space and invades the submandibular space it may be called ''plunging ranula''. Its etiology is not completely known. Our clinical case is a clear example: a 10-year old formation, not painful, developed during several years and originally of small dimension located in the sublingual region. The purpose of this study is to underline that the surgical treatment of choice, in these clinical situations, is the drainage of the cavity and marsupialization rather than a radical removal.
