Learn about CT Scans for Sinus Problems

Sinus allergies, often referred to as allergic rhinitis or hay fever, are typically caused by your immune system overreacting to allergens—substances that are normally harmless but trigger inflammation in sensitive individuals.

✅ Key Benefits of a Sinus CT Scan:

1. Detailed 3D Visualization

   • CT scans produce cross-sectional images, helping doctors assess the full anatomy of the sinuses, nasal passages, and surrounding structures.

2. Accurate Diagnosis of Sinus Conditions

   • Helps detect sinusitis, nasal polyps, mucosal thickening, blockages, and congenital abnormalities.

3. Identifies Hidden Infections or Abscesses

   • Especially useful when sinus infections don’t respond to treatment, revealing underlying or deep-seated infections.

4. Surgical Planning

   • Essential for planning sinus surgery, such as endoscopic sinus surgery, by mapping out the sinuses and any obstructions.

5. Noninvasive & Quick

   • The scan typically takes only a few minutes and is painless, with no scopes or contrast dye in most cases.

6. Assesses Bone Structures

   • Useful for evaluating fractures or structural problems in the facial bones or sinus walls.

Why Are Sinus Allergies Common in Spring?

Spring triggers a surge in airborne pollen, especially from:

• Trees like oak, birch, cedar, maple, and elm (typically March–May)

• Early grasses in some regions

This pollen can trigger allergic rhinitis, leading to sinus inflammation, nasal congestion, and post-nasal drip.

✅ Common Causes of Sinus Allergies:

1. Pollen

   • From trees, grasses, and weeds

   • Seasonal allergies are most often triggered by pollen

2. Dust Mites

   • Microscopic bugs that live in house dust

   • Found in bedding, carpets, and upholstered furniture

3. Pet Dander

   • Tiny flakes of skin shed by cats, dogs, and other furry animals

4. Mold Spores

   • Grows in damp, humid environments like basements, bathrooms, and outdoors in leaf piles

5. Cockroach Droppings

   • A common indoor allergen, especially in urban areas

6. Airborne Irritants

   • Smoke, strong perfumes, air pollution, and cleaning chemicals can aggravate allergy symptoms even if they aren’t true allergens

7. Food Allergies (less common)

   • Some people with food allergies may also experience sinus inflammation, although this is less typical

🧠 How Allergies Affect the Sinuses:

When you’re exposed to an allergen, your body releases histamine, which causes:

• Swelling of the sinus lining

• Increased mucus production

• Nasal congestion and pressure

• Sneezing and post-nasal drip

Chronic exposure can lead to sinus infections or sinusitis if drainage is blocked.
