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.
are a form of radiation, like light or radio waves, that are focused into a
beam, much like a flashlight beam. X-rays can pass through most objects,
including the human body. X-rays make a picture by striking a detector that
either exposes a film or sends the picture to a computer. Dense tissues in the
body, such as bones, block (absorb) many of the X-rays and look white on an
X-ray picture. Less dense tissues, such as muscles and organs, block fewer of
the X-rays (more of the X-rays pass through) and look like shades of gray on an
X-ray. X-rays that pass only through air, such as through the lungs, look black on the picture.
A facial X-ray helps find bone
fractures, tumors, 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
- Find problems of the sinuses of the face and
nose, such as
sinusitis or abnormal growths (polyps or
- Find fractures of the facial bones and
- Check the bones around the eye (orbital
- Check the sinuses before surgery.
- Check for
metal objects around the eyes before a
magnetic resonance imaging (MRI)
- Look for the cause of pain in the face.
