Sialography
Sialography
Sialography (pronounced: si·al·og·ra·phy, /sīˈaləˌɡrafē/) is a radiographic examination of the salivary glands that is used to investigate a variety of glandular disorders.
Etymology
The term 'Sialography' is derived from the Greek words 'sialon' meaning 'saliva', and 'graphy' meaning 'to write or record'.
Procedure
Sialography involves the injection of a radiopaque contrast medium into the ductal system, which can then be visualized using X-ray imaging. This allows for the detection of any structural or functional abnormalities within the glands.
Indications
Sialography is typically indicated for patients presenting with symptoms of sialadenitis (inflammation of the salivary glands), sialolithiasis (salivary stones), or other salivary gland disorders. It can also be used to assess the extent of damage in cases of trauma to the salivary glands.
Risks and Complications
As with any invasive procedure, sialography carries a risk of complications. These may include allergic reactions to the contrast medium, infection, or damage to the salivary glands.
