A facial X-ray is a series of pictures of the bones in the face. One type of facial X-ray (called a paranasal sinus X-ray series) looks at the air-filled cavities (sinuses) around the nose and eyes.
A facial X-ray helps find bone fractures, tumours, foreign objects, infections, and abnormal growths or changes in bone structure or size. An X-ray of the eye (orbital cavity) may be taken if the eye has been injured. A computed tomography (CT) scan may be needed to check any problems seen on X-ray.
Why It Is Done
A facial or sinus X-ray may be done to:
Find problems of the sinuses of the face and nose, such as sinusitis or abnormal growths (polyps or tumours).
In general, there's nothing you have to do before this test, unless your doctor tells you to.
How It Is Done
You will need to remove any jewellery that may be in the way of the X-ray picture. You will also need to remove glasses or dentures. You may be asked to lie on an X-ray table or sit in a chair. Several views (a series) of X-ray pictures are needed for clear pictures of the face. Your head may need to be repositioned for each view. Hold your head completely still while the pictures are being taken. A padded brace, foam pads, a headband, or sandbags may be used to hold your head in place while the pictures are taken.
If pictures of the orbital cavities or sinuses are needed, you will probably sit up while they are taken. A padded brace may be used to hold your head still while the pictures are taken.
How long the test takes
Facial X-rays usually take about 10 to 20 minutes. You will wait about 5 minutes until the X-rays are processed in case repeat pictures need to be taken. In some clinics and hospitals, X-ray pictures can be shown right away on a computer screen (digitally).
You won't feel any pain from the X-ray itself. You may find that the positions you need to hold are uncomfortable or painful. This is more likely if you have an injury.
There is always a slight chance of damage to cells or tissue from radiation, including the low levels of radiation used for this test. But the chance of damage from the X-rays is extremely low. It is not a reason to avoid the test.
If you need an X-ray during pregnancy, a lead apron will be put over your belly to protect the baby from exposure to radiation from the X-rays. The chance of harm is usually very low compared with the benefits of the test.
In an emergency, the doctor can see the initial results of a facial X-ray in a few minutes. Otherwise, a radiologist usually has the official X-ray report ready the next day.
