Abbreviations
- Simple ranula (SR), diving ranula (DR)
Synonyms
- Sublingual gland mucocele, mucous retention cyst
- DR is also referred to as plunging ranula
- Sublingual gland mucocele, mucous retention cyst
Definitions
- Retention cyst resulting from trauma or inflammation of sublingual gland (SLG) or minor salivary glands in sublingual space (SLS)
- SR: Postinflammatory retention cyst of SLG or SLS minor salivary glands with epithelial lining
- Located above mylohyoid muscle near SLG
- DR: Extravasation pseudocyst; term used when SR becomes large & ruptures out of posterior SLS into submandibular space (SMS), creating pseudocyst lacking epithelial lining
- SR: Postinflammatory retention cyst of SLG or SLS minor salivary glands with epithelial lining
- Term ranula derives from Latin "rana" = frog
- Sublingual blebs in mouth of frog resemble SR
- Retention cyst resulting from trauma or inflammation of sublingual gland (SLG) or minor salivary glands in sublingual space (SLS)
