Rhinosinusitis is an inflammation of the nasal mucosa and paranasal sinuses, affecting more than 31 million Americans. Acute rhinosinusitis lasts up to 4 weeks and results from infection. Chronic rhinosinusitis lasts 12 or more weeks and is caused by various inflammatory processes. Symptoms may be similar, but management options differ.
