Sinusitis is defined as "an inflammatory process of the mucous membranes of the paranasal sinuses that occurs in three stages: acute, subacute, and chronic. Sinusitis results from any condition causing ostial obstruction or from pathophysiologic changes in the mucociliary transport mechanism."[1]

Etiology/causes

Microbiology

Diagnosis

History and physical examination

A systematic review by the Rational Clinical Examination has reviewed the best findings.[2]

CT Scan

Interpreting abnormal CT scan results is difficult because most patients with a common cold will have abnormalities of the maxillary sinuses.[3]

Treatment

Topical antibiotics do not seem to help.[4]

Topical corticosteroids do not seem to help.[4]
