| Definition: |
This is a disorder caused by the presence of crystallized minerals in the ducts that drain the salivary glands.
|
| Alternative Names: |
Sialolithiasis
|
| Causes, incidence, and risk factors: |
Salivary duct stones are one of the salivary gland disorders.
The chemicals in saliva can crystallize into a stone that can block the salivary ducts. During eating, saliva is produced by the gland. When saliva cannot exit a blocked duct, it backs up into the gland, causing pain and swelling of the gland. The submandibular gland is the salivary gland that is most often affected by stones. |
| Symptoms: |
|
Note: Symptoms are most pronounced when eating or drinking. |
| Signs and tests: |
An examination of the head and neck by the health care provider or dentist shows one or more enlarged, tender salivary glands. The stone may be palpable during examination.
Facial X-rays confirm the diagnosis. |
| Treatment: |
| The goal of treatment is removal of the stone. Manual manipulation by the health care provider or dentist may relieve the obstruction when the stone is pushed out of the duct. Surgical excision (cutting) may be required to remove the stone in some cases. |
| Expectations (prognosis): |
Salivary duct stones are uncomfortable, but not dangerous. The stone is usually removed with only minimal discomfort.
Repeated stones or infections may indicate a need for surgical removal of the affected salivary gland. |
| Calling your health care provider: |
| Call your health care provider if symptoms indicate that salivary duct stones may be present. |
| Prevention: |
| There is no known prevention. |
