About this procedure
Salivary gland ultrasound is a non-invasive way to examine accessible parotid and submandibular glands when there is swelling, a lump, pain or suspected blockage. The scan helps guide assessment but cannot always establish a final diagnosis.
What this topic means
Salivary tissue may enlarge because of inflammation, a duct blockage, a benign condition or another disease. Pain around meals may be relevant, but a swelling should not automatically be labelled a stone or tumour.
When to seek medical advice
Tell the clinician about swelling near the ear or below the jaw, a firm area, painful meals, dry mouth, redness or fever. Rapidly worsening swelling or signs of infection need prompt assessment beyond a routine imaging appointment.
Options and limitations
Ultrasound can examine gland size, structure, certain visible ducts and nearby lymph nodes. Small or deeply located abnormalities may need additional imaging or specialist examination. The result does not replace an ENT or other relevant clinician's evaluation.
Assessment and preparation
A transducer and gel are applied over the skin, usually without special preparation. The specialist documents the gland and any focal findings; symptoms, physical examination and sometimes further tests determine their significance.
Treatment, risks and follow-up
The scan does not remove a stone or treat infection. Depending on the established cause, the clinician may recommend observation, medication or further specialist management. Never insert sharp objects into a salivary duct in an attempt to remove a stone.
When urgent help is needed
Rapid swelling of the neck or floor of the mouth with trouble breathing or swallowing needs immediate emergency help: call 103 or 112. Fever, pus, severe pain or spreading redness also warrants urgent in-person assessment.

Frequently asked questions
Is preparation needed before a salivary gland ultrasound?
Usually no specific fasting or medication preparation is required. Follow the imaging unit's instructions and bring previous results.
Will ultrasound identify every salivary stone?
No. Some stones may be visible, but the scan can miss small or poorly accessible obstructions.
Does the scan replace an ENT consultation?
No. The result must be considered together with examination and symptoms to determine further care.
Important information
A medical consultation is needed for diagnosis and treatment recommendations.
Self-treatment can be harmful to your health.
