Ranula
Pronunciation: RAN-yoo-lah
Fluid-filled swelling in the floor of the mouth caused by obstruction or trauma to sublingual or submandibular salivary glands.
Full Definition
A ranula is a mucocele specifically occurring in the floor of the mouth, typically arising from the sublingual gland or Wharton's duct. These lesions appear as translucent, blue-tinged swellings that may fluctuate in size. Simple ranulas remain confined to the sublingual space, while plunging (diving) ranulas extend through the mylohyoid muscle into the submandibular space, presenting as neck swelling. Treatment options include marsupialization, excision with involved gland removal, or CO2 laser ablation. Recurrence is common with inadequate treatment, making complete excision of the involved gland the preferred approach for definitive management. Large ranulas may interfere with speech, swallowing, or denture retention.
Usage
Usage note: Distinguish between simple and plunging types; specify treatment approach in documentation.
