Chronic Sinusitis

Chronic sinusitis is long-lasting inflammation of the lining of the nose and sinuses that continues for at least 12 weeks. Nasal blockage, thick drainage, facial pressure and a reduced sense of smell are common complaints. ^[1][2]

What is Chronic Sinusitis?

The condition is often called chronic rhinosinusitis because both the nose and the sinuses are involved. It is different from a short viral illness because symptoms persist or return repeatedly over a long period. ^[1][3]

What are the symptoms and what causes it?

Common symptoms include blocked nose, drainage from the nose or into the throat, facial pressure, cough and reduced smell. Causes can include allergy, nasal polyps, anatomical narrowing, asthma, smoking exposure and immune or inflammatory conditions. ^[1][2][3]

How is it diagnosed?

Diagnosis usually starts with a symptom history and ENT examination. Nasal endoscopy and sinus CT may be used when symptoms are persistent, one-sided, recurrent or when surgery is being considered. ^[1][2]

What are the treatment options?

Treatment commonly includes saline irrigation, intranasal steroid sprays and treatment of contributing factors such as allergy. Antibiotics are not needed in every case. Some patients benefit from endoscopic sinus surgery when medical treatment is not enough. ^[1][2][4]

Possible complications and when to seek medical care

Poorly controlled disease can worsen sleep, asthma and quality of life. Swelling around the eyes, vision change, high fever, severe headache or neurologic symptoms need urgent assessment. ^[1][2][3]

What may help in daily life?

Avoid smoke and irritants, use nasal treatments correctly and follow the care plan consistently. A structured follow-up often works better than repeatedly changing treatments on your own. ^[2][3]

Common mistakes during follow-up

Common mistakes include overusing decongestant sprays and treating every flare as if it automatically requires antibiotics. ^[2][4]
