A ranula is a pseudocyst caused by mucous extravasation of the sublingual gland or other minor salivary gland in the floor of the mouth. Ranula can be congenital, usually the result of abnormal drainage from the sublingual gland or acquired from oral trauma. Ranula are classified as intraoral if they are confined to the floor of the mouth, presenting as a painless swelling of the oral floor of the mouth. Conversely, a plunging ranula refers to a pseudocyst that extends through the mylohyoid muscle, presenting as a fluctuant swelling of the upper neck. The main complication of ranula is recurrence which typically occurs in the floor of the mouth. A plunging ranula is responsible for cervical swelling after herniation of the pseudocyst through the mylohyoid muscle. The optimal treatment of ranulas, simple as well as plunging, remains controversial. Various treatment modalities are available, ranging from conservative surgical techniques to more radical treatments just as varied. The best treatment to avoid recurrence is removal sublingual gland for oral and plunging ranula. Micromarsupialisation for oral ranula and sclerotherapy with OK-432 for plunging ranula allows less invasive procedure.
