IntroductionShow [+]Hide [-]

What is a Parotid Sialogram?
A parotid sialogram is an x-ray examination to explore the small gland that produces saliva situated inside the cheek

Why do I need this examination?
You usually require the examination because you have had a problem with swelling or pain in the gland area.

During Your ExaminationShow [+]Hide [-]

What does the examination involve?
You will be asked to sit in the dental chair and the radiologist will explain the examination to you and look in your mouth. There is a natural opening in the cheek inside your mouth to the gland where saliva comes out. The radiologist will use a small probe to locate this opening to establish its size and to stretch it open a little to accommodate a small hollow tube called a catheter. They will insert the end of the catheter into the opening of the gland and fix it in position with some tape attached to your face. They will then inject approx. 2mls of contrast media (liquid) through the catheter into the duct so it can be seen on the x-rays. The radiographer will then take an x-ray of the gland. The catheter will then be removed and you will be asked to rinse your mouth. A final x-ray is taken to ensure the gland has emptied and then you will be free to leave the department.

How long will it take?
The examination will take about half an hour to complete.

Will it hurt?
The examination is not painful but you may experience some discomfort when the liquid is injected into the gland.

What information will the dentist require from me?
The radiologist will require a brief medical history and a list of medication you are taking.

After Your ExaminationShow [+]Hide [-]

Will I have any after effects?
You may have a slight swelling of the area after the examination but this will return to normal after a short while. If you have any persistent problems or unusual symptoms you can call the Dental Hospital Radiology Department Monday to Friday 9.00 a.m. to 5.00 p.m. on 0191 2824691. Outside of these hours please contact your GP.

When will I get the results?
The radiologist may discuss initial findings with you on the day but a full report will be sent to the person who referred you for the examination. You will get the results at your next appointment with that person.
