Plunging ranula - patient characteristics, treatment, and comparison between different populations.

Objectives: To review our clinical experience and characteristics of Finnish patients with plunging ranula and compare our results with reports from other populations.

Design: A retrospective study from the electronic hospital records between 2005 and 2016.

Setting: The Department of Otorhinolaryngology and Head and Neck Surgery of Helsinki University Hospital, Finland.

Results: We describe the characteristics and treatment of 41 patients with MRI-confirmed plunging ranula. Most of our patients were young adults and 88% of them were male. Surgery and sclerotherapy were used for treatment.

Conclusions: The vast majority of Finnish plunging ranula patients in our cohort were male, suggesting significant population-related differences in plunging ranula gender distribution. Transoral surgery seemed to result in lowest recurrence rate and was the most common treatment in our clinic.
