[Plunging ranula].
Saliva extravasation from the sublingual gland causes ductal lesion or obstruction and results in the formation of a ranula. It spreads through or behind the mylohyoid muscle situated on the neck. Most frequently it is located in the submandibular or submental region. The diagnosis of plunging ranula is simple if the signs of ranula are present in the intraoral cavity, whereas in case of a ranula localized on the neck definite diagnosis is made by histologic analysis of the pseudocyst that has been surgically excised in toto. Cases are presented of both types of plunging ranula treated by various surgical approaches. Plunging ranula in the submental region was treated by transoral approach, marsupialization and aspiration of the content, whereas the ranula in the submandibular region was treated by exterior cervical approach. In both cases, sublingual gland was removed. During the 3.5-year follow-up, neither recurrence of the disease in the neck area nor the occurrence of simple ranula in the intraoral region was observed.
