Stones can be found in the salivary glands. Of the various salivary glands, the submandibular gland which is on the floor of the mouth is often blocked by stone. The stone is associated with chronic infection, dehydration, Sjogren’s syndrome and increase in calcium level.
Symptoms include pain which originate in the mouth and may radiate to the neck. The symptoms are worse during meals when increase salivary flow occurs. The other symptom is swelling under the jaw line corresponding to the gland location.
Diagnosis is from a classical history and examination. Radiology can also help confirm the diagnosis.
If the stone is small. symptomatic treatment is helpful. If it is in the duct, it can occasionally be removed through the duct in the mouth. If the stone is lodged in the gland, excision of the gland may be necessary.
