Sinusitis is characterized by inflammation of the lining of the paranasal sinuses. Because the nasal mucosa is simultaneously involved and because sinusitis rarely occurs without concurrent rhinitis, rhinosinusitis is now the preferred term for this condition. Rhinosinusitis affects an estimated 35 million people per year in the United States and accounts for almost 16 million office visits per year. Additionally, chronic sinusitis is one of the more prevalent chronic illnesses in the United States, affecting persons of all age groups. Test your knowledge of sinusitis with our quick quiz.
