Why Get a Sinus CT?

By Dr Madeleine Herman, MD, FAAOA

If you suffer from frequent sinus infections, chronic congestion, or persistent nasal problems, your ENT specialist may recommend a sinus CT scan. Many patients wonder why this test is necessary and how it helps guide their care.

At SCENT Houston – Sinus Center & ENT Specialists of Houston, we believe in educating our patients so they feel comfortable and informed about every step of their treatment.

What Is a Sinus CT Scan?

A sinus CT (computed tomography) scan is a special type of X-ray that produces detailed images of your sinuses and nasal passages. Unlike a standard X-ray, a CT scan shows cross-sectional views, allowing your ENT to see fine details of the bone, tissue, and air spaces.

Why Is a Sinus CT Helpful?

A sinus CT provides valuable information that cannot be seen with a physical exam alone. It helps your ENT specialist to:

• Identify sinus blockages – Determine if swelling, infection, or polyps are blocking normal drainage.

• Evaluate sinus anatomy – Detect structural issues such as a deviated septum, enlarged turbinates, or narrow drainage pathways.

• Guide treatment decisions – Decide if medical management, in-office procedures, or surgery is the best option for your condition.

• Plan surgery safely – If sinus surgery is needed, the CT scan acts like a map, helping your surgeon avoid critical structures like the eyes and brain.

What Conditions May Require a Sinus CT?

Your ENT may recommend a sinus CT if you experience:

• Chronic sinus infections that don’t improve with antibiotics

• Persistent nasal congestion or obstruction

• Facial pressure, pain, or headaches

• Recurrent sinus symptoms despite treatment

• Concerns about nasal polyps or chronic sinusitis

Is a Sinus CT Safe?

Yes. A sinus CT uses a low dose of radiation, and modern scanners minimize exposure while providing high-quality images. The scan is quick, painless, and usually completed in less than 10 minutes.
