Secondhand Smoke Increases Chronic Rhinosinusitis Risk

Is exposure to secondhand smoke a risk factor for chronic rhinosinusitis (CRS)?

Background: There are surprisingly few studies that address the association between secondhand smoke (SHS) and sinusitis, and most use fairly weak criteria for sinusitis, such as a patient’s having checked “sinusitis” on a health questionnaire. There are, however, several studies that address the effects of SHS on lower airway diseases such as asthma and bronchitis.

Study Design: Population-based case-control study
