How is Sialography done?

How is Sialography done?

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.

Why does a patient undergo a Sialography procedure?

Why is a sialogram performed? Your doctor can use a sialogram to evaluate blockages in a salivary duct or gland. Your doctor may recommend a sialogram if you have one or more of the following symptoms: a constant abnormal or foul taste in your mouth.

What is a sialogram test?

A sialogram is an x-ray test using contrast (x-ray dye) to look in detail at the larger salivary glands (the parotid or submandibular). These glands help to keep your mouth moist by draining saliva into your mouth through small tubes called ducts.

How do you Parnulate your parotid duct?

Management of parotid duct injuries. The common diagnostic technique includes cannulation of the duct with injection of a disclosing solution such as methylene blue. Many references to this technique suggest using lacrimal probes to dilate the papilla and subsequently cannulate the duct with a silicone catheter.

What are the indications 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 contrast media is used for sialography?

Conray 80, Amipaque 440, Lipiodol UF, Myodil, and Duroliopaque appear to be the media most suited for sialography, provided glandular overfilling is avoided. A prolonged clinical study is advised for a further selection from these agents.

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 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.

Where does parotid duct drain?

The parotid glands are located in front and beneath the ear. A duct, called Stensen’s duct, drains saliva from the parotid gland into the mouth, at the area of the upper cheeks. The submandibular glands are found on both sides, just under and deep to the jaw, towards the back of the mouth.
