Sialography : Parotid/ Submandibular

Sialography (also termed radiosialography) is the radiographic examination of the salivary glands. It usually involves the injection of a small amount of contrast medium into the salivary duct of a single gland, followed by routine X-ray projections.

The resulting diagram is called a sialogram.

Indications include:

  • In the evaluation of the functional integrity of the salivary glands
  • In case of obstructions
  • To evaluate the ductal pattern
  • In case of facial swellings, to rule out salivary gland pathology
  • In case of intra-glandular neoplasms.

Contraindications include:

  • Persons who are allergic to iodine and/or contrast medium.
  • Cases where there is acute infection,
  • patients with thyroid function tests
  • When calculi are located in anterior part of the salivary gland duct
