Inflammation of the paranasal sinuses lasting more than 12 weeks.
Diagnosis is initially clinical. Nasal endoscopy may show inflammation, purulent discharge, edema, or frank polyps.
Medical treatment includes prolonged courses of antibiotics, corticosteroids (intranasal or systemic), saline irrigation, antihistamines, and leukotriene receptor antagonists.
CT is needed if initial medical treatment fails.
Functional endoscopic sinus surgery is very effective for patients unresponsive to medical treatment.
Chronic sinusitis is inflammation of the paranasal sinuses lasting more than 12 weeks. Symptoms include facial pressure, rhinorrhea, postnasal drainage, congestion, and general malaise. Chronic sinusitis is divided into 2 groups, with and without polyps, which have slightly different treatment regimens. This monograph discusses chronic sinusitis in the absence of polyps. There is a separate monograph covering nasal polyps.
