Overview
Salivary gland stones (sialolithiasis) are mineral deposits that form in the ducts of the salivary glands. These stones can block the flow of saliva, leading to pain and swelling, particularly during or after meals.
Common symptoms
- Painful swelling under the jaw or in front of the ears
- Symptoms that worsen when eating (when saliva flow is stimulated)
- Dry mouth (xerostomia)
- A palpable lump in the floor of the mouth or cheek
- Recurrent infections (sialadenitis) in the affected gland
When to see an ENT
- Persistent or recurrent swelling of the salivary glands
- Severe pain or redness over the gland
- Fever or pus-like discharge in the mouth
- A visible or palpable stone in the mouth
What we do
- Detailed history and physical examination, including bimanual palpation of the glands
- Nasoendoscopy if needed to check the throat
- Ultrasound, CT, or Sialogram to locate and size the stone(s)
Management options
- Conservative: Hydration, massage, and sialogogues (sour sweets) to encourage saliva flow
- Antibiotics if infection is present
- Minimally invasive removal of the stone in clinic (if near the duct opening)
- Sialendoscopy: Using a tiny camera and instruments to remove stones from within the duct
- Surgical removal of the salivary gland in severe or recurrent cases
