What is this test?
CT (Computed Tomography) scan of the paranasal sinuses is an imaging technique that uses X-rays to create detailed cross-sectional images of the sinus cavities surrounding the nose and eyes. This scan provides high-resolution visualization of the bony structures, air spaces, and soft tissues within the sinuses, helping doctors evaluate sinus health with precision.
What is it used for?

• Diagnosing sinusitis (inflammation or infection of the sinus cavities), especially chronic or recurrent cases
• Detecting nasal polyps, which are soft growths that can block sinus drainage
• Identifying tumors or cysts in the sinus or nasal passages
• Assessing anatomical abnormalities like deviated septum, concha bullosa, or narrow sinus openings that may contribute to sinus problems
• Guiding surgical planning for sinus surgeries such as functional endoscopic sinus surgery (FESS)
• Evaluating complications of sinus infections, such as spread to nearby bones or the orbit

Who should get this test?

• Patients suffering from persistent or recurrent sinus infections that do not improve with standard treatments
• Individuals with chronic nasal congestion, facial pain or pressure, or headaches linked to sinus issues
• Patients with suspicion of sinus tumors or polyps
• Candidates for sinus surgery requiring detailed anatomical mapping
• Patients with unexplained nasal obstruction or drainage abnormalities

Preparation Required:

• No special preparation or fasting is necessary before the scan
• Removal of any metallic items near the head, such as earrings or glasses, is required
• Inform your healthcare provider if you are pregnant, as radiation exposure should be minimized

How is the procedure performed?
The CT paranasal sinus scan is a rapid, painless procedure that typically takes 5 to 10 minutes. The patient lies on a table that slides into the CT scanner. Multiple thin, detailed images of the sinus cavities are taken using X-rays. The patient must remain still during the brief scan for optimal image clarity.
Risks & Safety:
This scan involves exposure to ionizing radiation, which is generally low but important to consider, especially in children or those requiring multiple scans. The benefits of accurate diagnosis usually outweigh the small radiation risk. No contrast agents are usually required, so allergic reactions are uncommon.
Results:
A radiologist reviews the images to assess the sinus anatomy and identify any signs of infection, blockage, polyps, tumors, or structural abnormalities. The report helps guide treatment decisions, whether medical management or surgery, and may identify complications requiring urgent attention.
Short Statement:
A detailed CT scan of the sinus cavities that helps detect blockages, infections, polyps, or structural issues — critical for diagnosing chronic sinusitis or planning sinus surgery.
