Sinusitis symptoms:when is sinusitis considered chronic?

Rhinosinusitis is inflammation of the nasal and sinus lining that produces a cluster of nasal symptoms such as blockage, discharge, smell change, or facial pressure.

The term helps avoid the idea that disease sits only in a “sinus cavity” with no nasal involvement. In practice, most symptoms are felt through the nose and sinus drainage pathways.

Diagnosis is based on clinical pattern and evaluation, not on casual naming of every facial ache as sinus disease.

Acute rhinosinusitis usually refers to a shorter illness, often after a cold. Chronic rhinosinusitis (CRS) is generally considered when symptoms persist for about 12 weeks or longer.

In guidance such as EPOS, calling disease “chronic” is not only the patient’s sense that it has lasted a long time. Symptoms should meet criteria and be supported by objective findings from examination — for example endoscopy or imaging when indicated.

Early post-cold sinus symptoms are often viral inflammation. Bacterial infection can occur in some people, but green mucus does not automatically mean antibiotics are required.

Mucus colour and thickness can reflect inflammation and cellular debris. They are not a culture result. Green or yellow discharge does not diagnose bacterial disease by itself.

Clinicians weigh duration, severity, associated findings, and examination — not mucus colour alone.

Assessment starts with symptom history, duration, associated features, and nasal examination by an ENT clinician.

Nasal endoscopy helps inspect the lining, mucus, drainage pathways, and polyps when visible. It is especially useful when chronic disease is suspected or the course is not as expected.

Sinus CT is not needed for everyone. It is often considered for persistent disease, incomplete response to appropriate care, suspected complications, or surgical planning — not as a first test for every short cold.

Chronic rhinosinusitis may occur with or without nasal polyps. Polyps change the clinical picture and follow-up, but they do not mean every patient needs immediate surgery.

Medical care often focuses on saline rinses, indicated medicines such as intranasal corticosteroids, and managing related conditions such as allergic rhinitis when relevant.

Sinus surgery may be considered when appropriate medical therapy is not enough, when structural disease or obstructing polyps are clear, or when other findings support it. It is not first-line for every short illness, and lasting results are not guaranteed for everyone.
