What is Sialography Slideshare?

SIALOGRAPHY INTRODUCTION  A radiographic examination of the salivary glands(PAROTID & Submandibular GLAND) and ducts using contrast media  Cannulation of Sublingual gland ducts is almost impossible.

How do you do Sialography?

Technique of conventional sialography

1. control images are taken with the patient supine to assess for radiopaque calculi.
2. the patient may be asked to suck on a lemon or secretory stimulant for 2-3 minutes before sialography.
3. symptomatic parotid or submandibular duct cannulated.

Why is Sialography important for evaluation of Gustation?

A sialogram is a test your doctor can use to diagnose a blocked salivary gland or duct in your mouth. Salivary glands release saliva into your mouth through salivary ducts. A free flow of saliva to the mouth is important for digestion and general oral health.

Do you think Sialography is still an essential procedure these days?

Hence, sialography remains an indispensable choice for detailed assessment of the salivary glands when compared to the above mentioned imaging modalities as it is simple to perform, quick and almost a pain free diagnostic procedure.

What is Sialographic appearance of normal salivary gland?

A space occupying lesion that occurs within or adjacent to a salivary gland can displace the normal anatomy of the gland. This may create an appearance known as “ball in hand” on an sialogram, where the ducts are curved around the mass of the lesion.

Can we use water based contrast media for Sialography?

Due to potential problems with retention of oil-based contrast media (especially in cases of with extrusion outside of the duct or gland) we (H Hoffman, U of Iowa) have limited our practice of sialography since 2008 to use of water-soluble iodinated contrast medium.

What is the indication of Sialography?

It provides both diagnostic and preoperative information in cases of salivary gland pathology. Other indications for sialography are calculi, strictures of the ducts, sialectasia (dilation of a duct), fistulas, and demonstration of pleomorphic salivary gland tumors, commonly called mixed parotid tumors.

What is the importance of studying Sialography?

Sialography is used to demonstrate the anatomy of the drainage system and is a very useful test. Injury to the ducts or acini is demonstrated with this study. Many radiologists no longer perform the test, which is unfortunate.

Why is sialography performed?

A sialogram is performed to diagnose blockage of the salivary flow due to stones or strictures. This examination is done by introducing a very thin tube into the opening of the duct and injecting a small amount of liquid.

What is injected in sialography?

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 image is called a sialogram.
