[Plunging ranula].

The plunging ranula is a relatively uncommon phenomenon which represents a mucus escape reaction occurring from disruption of the sublingual salivary gland. We present a retrospective study over a 10 years period on patients suffering of plunging ranula treated in Oral and Maxillo-Facial Clinic, resumed by a clinical example. These 7 patients with plunging ranula are related to all the patients operated for ranula in the same period of time in our clinic and were analyzed on age, sex, imaging exploration technique, treatment, and outcome.
