Highlights & Basics
- Chronic rhinosinusitis is 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.
- Initial medical treatment includes nasal saline irrigation and topical intranasal corticosteroids. Oral antibiotics, oral corticosteroids, antihistamines, and leukotriene receptor antagonists may also be considered.
- Computed tomography is needed if initial medical treatment fails.
- Functional endoscopic sinus surgery is very effective for patients unresponsive to medical treatment.
