Ranula refers to mucous retention cyst or mucocele that develops on the oral floor and it appears most frequently among oral masses derived from salivary glands. Ranula that is extended into submandibular space or into other cervical spaces due to defective mylohyoid muscle is particularly called plunging ranula. Various types of treatments have been conducted for ranula: surgical treatments such as simple excision, marsupialization, and removal of sublingual gland; and sclerotherapy utilizing OK-432 (Picibanil) are being reported. We performed concurrent excision of ranula and sublingual gland through intraoral approach. This technique leaves no post-surgical scars and shows very low recurrence rate and incidence rate of complications. Therefore, in this study, we would like to analyze the treatment methods and results of our patients.
