Chronic rhinosinusitis without nasal polyps

Prevention mainly entails avoidance of acute exacerbations through maximal treatment. Many patients also benefit from nasal saline irrigations 2-3 times per day to prevent secretory stasis. Maintenance therapy with other topical medications, such as nasal corticosteroid spray in polypoid disease, may be required. Managing other risk factors including allergic rhinitis and smoking is beneficial.
