What is Chronic Rhinosinusitis?

(See "Microbiology and antibiotic management of chronic rhinosinusitis".) CRS is defined as an inflammatory condition involving the paranasal sinuses and linings of the nasal passages that lasts 12 weeks or longer [1,6]. The diagnosis requires objective evidence of mucosal inflammation.

Worsening of symptoms may involve sudden nasal congestion, pain and pressure in the sinuses, runny nose, red/watery eyes, wheezing, chest tightness, and cough. These reactions can be severe and even life threatening.

Allergies that are poorly controlled can worsen the symptoms of chronic rhinosinusitis. (See "Patient education: Allergic rhinitis (Beyond the Basics)".) Exposure to tobacco smoke or airborne irritants – Exposure to cigarette smoke or certain environmental irritants can increase the risk of chronic rhinosinusitis.

Primary prevention of CRS focuses on the avoidance of exposure to environmental factors associated with increased incidence of disease. This includes avoidance of tobacco smoke and occupational toxins.
