Radiology - Sialogram

What is a Sialogram?

A sialogram is an xray investigation to look at the salivary ducts and glands in your mouth. There are two main salivary glands that are examined by xray and these are; the sub-mandibular glands, which empty saliva into the mouth just under the tongue, and the parotid glands, which empty saliva into the inside of the cheek.

Who performs your investigation?

A radiologist or specially trained radiographer will perform this investigation. Radiologists are doctors specially trained to interpret the images and carry out more complex examinations. The examination may be carried out by a specially trained radiographer. They have been specially trained to perform these examinations. They are supported by radiographers who are highly trained to carry out xrays and other imaging procedures.

Are you required to make any special preparation?

There is no preparation for this investigation. However, if your gland is infected please contact the radiology booking centre on 0161 778 2233 to cancel this appointment and make a new one.

What does the investigation involve?

Once you have arrived in the xray department, the investigation will be explained to you and you will be taken into the xray room.

You will then be asked to lie on the xray table and some control xrays will be taken. A small, thin tube will then be placed into the opening of the gland in your mouth and some xray dye (contrast) will be administered through this tube. Three or four xrays will then be taken whist the gland is outlined with the dye. No needles are involved as there are already holes in your cheeks and under your tongue where the small tube will be inserted.

You will then be asked to swill your mouth out with lemon juice to empty the salivary glands and a further xray is taken to make sure the gland has emptied. If you have an allergy to lemon/ citrus juice please make us aware when you come for your investigation and we will avoid using it.

How long does the investigation take?

The investigation takes about 30 minutes.

Are there any side/after effects?

You may experience some swelling in the gland which you can gently massage and a warm compress may also help.

How do you get the results of your investigation?

The results of the investigation will be sent to the consultant that referred you for the investigation.
