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[edit | edit source]
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[edit | edit source]
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[edit | edit source]
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[edit | edit source]
Alternatives to sialography include ultrasound, computed tomography (CT) and MRI.
