  • Title: Chapter 4: Chronic rhinosinusitis.

    Abstract:
    Chronic rhinosinusitis (CRS) is the second most common chronic medical condition in the United States. It represents a group of disorders characterized by inflammation of the nasal mucosa and paranasal sinuses of at least 12 weeks duration. CRS with or without nasal polyps is defined as inflammation of the nose characterized by two or more symptoms, one of which should be either nasal blockage, obstruction, congestion, or nasal discharge (anterior/posterior nasal drip); with or without facial pain/pressure; and/or with or without reduction or loss of smell. Symptomatology should be supported by obvious disease evident in either nasal endoscopy or computed tomography imaging. Although CRS is not likely to be cured by either medical or surgical therapy, it can generally be controlled. Best medical evidence supports maintenance therapy with intranasal corticosteroids and saline irrigation. For exacerbations, short to intermediate courses of antibiotics (up to 4-weeks) with or without oral corticosteroids are recommended. For patients with difficult-to-treat CRS, functional endoscopic sinus surgery provides an adjunctive therapeutic option.
