Sinus
Sinusitis is an inflammation of the sinuses, the hollow cavities within the cheekbones, around your eyes and behind your nose. It is often caused by a bacterial infection and may occur following a respiratory infection such as the common cold. When something blocks the mucus in these cavities from draining normally, an infection can occur. People with allergic rhinitis (allergies) or asthma are more likely to suffer from chronic sinusitis because the airways are more likely to become inflamed when allergies or asthma are present.
Acute Sinusitis refers to sinusitis symptoms lasting less than 4 weeks. Most cases begin as the common cold. Symptoms often go away within a week to 10 days, but in some people, a bacterial infection develops and antibiotics may be required.
Chronic Sinusitis is often diagnosed when acute symptoms have gone on for more than 8 weeks despite medical treatment.
How is chronic sinusitis treated?
The allergist will conduct a medical history, including an assessment of your symptoms and a relevant physical exam to look for polyps or changes in the anatomy of the nose (if necessary, a CT scan will be ordered). The allergist may also conduct skin testing (link to skin testing) to determine which triggers are causing nasal swelling. Once the allergist knows the triggers that are causing your chronic symptoms, a treatment plan will be recommended.
Most treatment plans include:
When the underlying cause of chronic sinusitis is treated effectively, it frequently disappears or becomes less of a problem. Since allergies can lead to chronic sinusitis, immunotherapy (or allergy shots) (link to allergy shots) is the most effective long-term approach towards a cure. Immunotherapy is the only way to rid the body of nasal allergies. In essence, it is a vaccine against allergies. As you receive immunotherapy, you gradually decrease your sensitivity and build up a tolerance to your allergens.
