What is this test?

A maxillofacial CT scan is an imaging test that uses X-rays and a computer to create cross-sectional pictures of the bones and soft tissues of the face, jaw, mouth, and nearby sinuses. In this test, no intravenous contrast dye is used.

Why might I need this test?

Your clinician may order this scan to evaluate facial or jaw injuries, especially suspected fractures. It may also help assess abnormalities affecting the teeth, jawbone, facial bones, or paranasal sinuses, including unexplained swelling or persistent pain.

How is the test performed?

You will lie on a CT table while the scanner rotates around your head and neck. The scan is generally painless and usually takes only a few minutes, although you may be asked to remain very still.

How do I prepare for the test?

Call the imaging center for specific instructions. You may need to remove glasses, hairpins, dentures, and metal items near the scanned area. Tell the technologist if you are pregnant or may be pregnant, and follow any instructions about eating, drinking, or taking medicines.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Abnormal findings may include fractures, bone or soft-tissue abnormalities, dental and jaw problems, fluid or inflammation in the sinuses, or other structural changes. The results should be interpreted by a radiologist and considered alongside your symptoms, examination, and other tests.

No. The test name indicates that it is performed without intravenous contrast. Any imaging center instructions should be followed because additional views or other examinations may sometimes be recommended.
