Etiology, diagnosis and management of chronic rhinosinusitis

Abstract

Chronic rhinosinusitis (CRS) is a common health care problem, yet many aspects of this diagnosis remain poorly understood. Its etiology is often debated and remains a significant area of research. The diagnosis of CRS is based on subjective symptoms, duration of symptoms and objective evidence of inflammation. Each of these criteria must be met to make a diagnosis of CRS. Management of CRS often involves a combination of systemic and topical therapies with surgery reserved for patients who fail medical therapy. This review provides a comprehensive view of the etiology, diagnosis and management of CRS.
