What Happens During a CT Scan of the Sinuses?

Every breath feels heavier when your nose is stuffy. And eventually, you can end up with pressure building behind your eyes, or sinus infections keep coming back. Chronic sinus problems affect millions of Americans, with the Centers for Disease Control and Prevention reporting that nearly 29 million adults have been diagnosed with sinusitis that keeps coming back over and over again. 

When symptoms persist despite medication or other treatments, a CT scan of the sinuses is the best way to look beyond what is visible during a routine exam. While the idea of medical imaging can make some patients uneasy, a sinus CT scan is quick and painless. 

Read on to learn what happens before, during, and after a sinus CT scan with the best sinus doctor in Torrance, so you feel more comfortable with the process.

When is a Sinus CT Scan Necessary?

A sinus CT scan is an imaging test that creates detailed cross-sectional pictures of the sinuses and nasal cavity, including the soft tissues of the nasal passages and surrounding structures. Sinus specialists in Torrance recommend this test when sinus symptoms continue for weeks or months despite treatment. Symptoms that can all signal an underlying issue that requires a closer look include: 

• Ongoing nasal congestion
• Facial pain
• Pressure around the eyes
• Frequent sinus infections 
• Difficulty breathing through the nose 

Sinus CT scans can also reveal sinus inflammation and swelling, blocked drainage pathways, nasal polyps, structural abnormalities, or other conditions that may not be visible during a routine office examination.

What Can a Sinus CT Scan Diagnose?

One of the greatest benefits of a sinus CT scan is the amount of detail it provides. The images can diagnose a variety of conditions and structural abnormalities, including: 

• Chronic sinus infections, also known as recurring sinusitis
• Nasal polyps
• Deviated septum
• Sinus blockages 
• Sinus tumors
• Issues that affect breathing and drainage
• Narrowing of the sinus openings

These findings provide the best sinus specialist in Torrance with valuable information to guide medication recommendations, steroid nasal sprays to reduce inflammation, allergy management strategies, and surgical planning when necessary. 

Preparing for a Sinus CT Scan

Preparing for your scan requires very little. In most cases, you can eat, drink, and take your usual medications. Wearing comfortable clothing and leaving metal accessories, such as jewelry, at home can help make the appointment go more smoothly. 

Sinus CT scans are commonly performed without contrast dye, which means there is usually no need for injections or special dietary restrictions. Before the scan begins, the imaging team will review your medical history and answer any questions you may have. The scan itself takes only a few minutes. 

What Happens During a Sinus CT?

After arriving at the imaging center, a radiology technician will guide you and explain each step. During the scan itself, you will lie on a narrow table that moves slowly into the CT scanner. The machine is open on both ends and does not fully enclose the body. However, if you struggle with claustrophobia, medication can be prescribed to help you relax. 

During the scan, it is important to remain still so the images are as clear as possible. As the scanner rotates around your head, it captures detailed images of the sinus cavities from multiple angles. The process is painless, and once the scan is complete, you can return to your normal daily activities.

How Long Does it Take to Get Results After a Sinus CT Scan?

The timing of results varies depending on where you go for your scan, though most patients receive feedback within a day or two. During a follow-up appointment, the best sinus surgeon in Torrance will explain the findings, how they relate to your symptoms, and what the best course of action is. 

If the scan finds any sinus inflammation or any blockages or structural concerns, your treatment plan may include medication, allergy therapy, or image-guided sinus surgery in Torrance. The goal is to address the underlying cause of the problem so you don’t rely on medication forever.
