Salivary Mucocele
A salivary mucocele (sialocele) is a swollen area caused by saliva leaking from a damaged salivary gland or duct into surrounding tissues. Most commonly found under the jaw or under the tongue.
Key Facts
- Most common location: on or beneath the lower jaw, or under the tongue (ranula)
- Can interfere with eating, swallowing, or breathing if large enough
- Diagnosis: aspiration with needle and syringe; fluid examined under microscope
- Treatment: surgical removal of the diseased gland
- Multiple salivary glands exist; removing one does not significantly affect saliva production
- Draining alone is temporary; mucoceles refill with saliva
- Uncommon condition; recurrence after successful surgery is unlikely
- Species: dogs and cats
