A sinus X-ray is a scan that shows the air-filled spaces around your nose and eyes.
Your doctor may request it if you have persistent facial pressure, nasal blockage, or repeated sinus symptoms. CT gives more detail, but an X-ray may still help answer some basic sinus questions.
Common Indications for Sinus X-Ray
- Persistent facial pain or pressure
- Blocked nose that keeps coming back
- Suspected sinus infection with fluid
- Recurrent sinus symptoms
- Follow-up of known sinus disease
- Selected facial injury checks
What exactly does a sinus X-ray show?
It shows the main sinuses in the bones of the face. It may show clouding, fluid levels, thickened lining, or changes in the sinus walls.
How should I prepare for a sinus X-ray?
You do not need to fast. Remove glasses, earrings, hairpins, dentures, or metal objects around the head and face. Tell the radiographer if you cannot hold your head still.
Do I need to stop taking medication?
No. Keep taking your regular medication unless your referring doctor tells you otherwise.
What happens when I arrive for my scan?
The radiographer will confirm the request and explain the head positions needed. You may be asked to remove items that could cover the sinuses on the image.
How is the procedure performed?
You may sit or stand against the X-ray detector. The radiographer will position your head in different angles and ask you to keep still for each image.
How long does a sinus X-ray take?
The scan usually takes about 10 to 15 minutes. The visit is often short unless extra views are needed.
Is there any discomfort?
No. The X-ray itself is painless. Holding your head in position may feel awkward for a few seconds.
Are there risks?
A sinus X-ray uses a small amount of radiation. No radiation stays in your body after the scan. The team only takes the views needed.
Can children have this scan?
Yes. Children can have a sinus X-ray when it is clearly needed. Your doctor may choose another approach depending on the child's age and symptoms.
Can I have this scan if I am pregnant?
Pregnancy Precaution
Tell your doctor or radiographer if you are pregnant or think you might be. A sinus X-ray is focused on the face, but the team still needs to know before any X-ray.
When will I get my results?
A radiologist will review the images and send a report to your referring doctor. Timing depends on the centre and urgency.
What if the scan finds something?
Your referring doctor will explain the result with your symptoms in mind. You may need medicine, follow-up, or a more detailed scan if the question is not fully answered.
What can this X-ray miss?
Plain X-rays of the skull or face provide limited detail and do not assess the brain. CT is usually more informative for significant acute head or facial trauma, complex fracture, eye-socket injury, or complications of sinus disease. A normal X-ray should not delay further assessment when symptoms are concerning.
Seek urgent care after head or facial injury for loss of consciousness, repeated vomiting, increasing drowsiness or confusion, seizure, new weakness, unequal pupils, clear fluid from the nose or ear, or new loss of vision.
Questions to ask your care team
- What clinical question should this X-ray answer, and will the result change my treatment?
- Could an important injury or condition be missed on a plain X-ray, and what symptoms would justify repeat X-rays, ultrasound, CT, or MRI?
- Are special views needed, such as standing, weight-bearing, comparison, or low-dose views?
- When and how will I receive the radiologist's report, and who will explain the next step?

Conclusion
A sinus X-ray is a simple test for selected sinus problems. To make it smoother, remove facial metal items before the scan and tell the team if you are pregnant.
