Treatment of Acute Exacerbation (Flare) of Chronic Rhinosinusitis

An acute exacerbation of chronic rhinosinusitis is a sudden symptomatic worsening superimposed on underlying chronic sinonasal disease. This clinical scenario calls for a specific treatment approach that differs from routine maintenance management.

Current guidelines recognise acute exacerbations of chronic rhinosinusitis — occurring both with and without nasal polyps — as the specific setting in which antibiotic therapy may be appropriate. Presentations involving fever or severe pain warrant particular clinical attention.

Treatment approach

Management of this exacerbation centres on a defined course of oral antibiotic therapy. The complete regimen, selection criteria, and clinical sequencing are available in the full structured protocol.
