[Pediatric plunging ranula and its surgery with transoral approach: a case report].

The plunging ranula is an uncommon condition which presents itself as a fluctuating swelling in the neck. It is less frequent during childhood. The ranula, which is usually originated from sublingual gland, is called the plunging ranula when it affects the submandibulary space and adjacent structures in the neck. There are a lot of different methods used in surgical treatment. In this study, we present a plunging ranula case which was performed by excision of the pseudocyst and ipsilateral sublingual gland with transoral approach in a five-year-old girl. There has been no recurrence in four-year follow-up period.
