Sialography

Sialography is a radiographic examination of the salivary glands. It is used to investigate a variety of salivary gland disorders, including sialolithiasis, Sjögren's syndrome, and salivary gland tumors.

Procedure

The procedure involves the injection of a radiopaque contrast medium into the salivary duct of a single gland, followed by radiographs. The contrast medium outlines the tree-like structure of the gland, revealing any blockages or other abnormalities.

Indications

Sialography may be indicated in the following situations:

• Suspected sialolithiasis
• Evaluation of salivary gland tumors
• Diagnosis of Sjögren's syndrome
• Investigation of unexplained salivary gland swelling or pain

Risks

As with any procedure involving radiation, there is a small risk of radiation exposure. However, the benefits of sialography in diagnosing salivary gland disorders generally outweigh this risk. There is also a small risk of allergic reaction to the contrast medium.

Alternatives

Alternatives to sialography include ultrasound, computed tomography (CT) and MRI.
