Tobacco Use Increases the Adjusted Risk of Revision Endoscopic Sinus Surgery in Patients With Chronic Rhinosinusitis.

Background: Large epidemiologic studies have suggested that a history of tobacco use may be associated with an increased risk of developing chronic rhinosinusitis (CRS). The impact of tobacco use on revision rates of endoscopic sinus surgery (ESS), however, remains limited.

Objective: This study seeks to define the independent risk of tobacco use (active or prior) on revision rates of ESS among a large cohort of patients with CRS.

Methods: A state population database was queried for patients age ≥18 years with CRS who underwent at least one ESS between 1996 and 2018. Demographic characteristics, history of ESS, and tobacco use status were compared across patients with CRS, using tests for continuous variables and χ tests for categorical variables. Unadjusted and adjusted logistic regression models were used to understand the impact of tobacco status on revision surgery.

Results: The final analysis included 34 350 patients (29 916 CRS with no revision surgery and 4434 CRS with revision surgery). Unadjusted regression analysis demonstrated an increased odds of undergoing revision ESS (OR 1.12, 95% CI: 1.00-1.25,  = .05) among males with a history of tobacco use and CRS. Adjusted regression analysis demonstrated that the risk of revision ESS among CRS patients with a history of asthma and tobacco use was 1.72-fold, while the risk among CRS patients who were tobacco users without asthma was 1.11-fold.

Conclusion: History of tobacco use is an independent risk factor for revision ESS among patients with CRS.
