Secondhand Tobacco Smoke Exposure and Chronic Rhinosinusitis: A Population-Based Case–Control Study

Abstract

Exposure to SHS during childhood and adulthood may be a risk factor for CRS. Furthermore, compared with unexposed CRS cases, SHS exposed cases reported worse nasal symptoms and used more nasal decongestants compared with unexposed cases, suggesting SHS exposure is related to exacerbation and more severe symptoms.
