Tobacco use increases the risk of chronic rhinosinusitis among patients undergoing endoscopic sinus surgery.

BACKGROUND
Although it has been postulated that tobacco use, as well as other environmental exposures, may contribute to chronic rhinosinusitis (CRS), the data remain limited. Here, we utilized a large state population database to assess the association between tobacco use and CRS prevalence among patients undergoing endoscopic sinus surgery (ESS).


METHODS
Employing a case-control study design, the Utah Population Database was queried for patients age > 18 with a diagnosis of CRS and tobacco use who underwent ESS between 1996 and 2018. Smoking status was compared between patients with CRS (n=34,350) and random population controls matched 5:1 on sex, birth year, birthplace, time residing in Utah, and pedigree (i.e., familial) information (n=166,020). Conditional logistic regression models were used for comparisons between CRS patients and their matched controls. All analyses were repeated, additionally adjusting for race, ethnicity, tobacco use, asthma history, and interaction between tobacco use and asthma history.


RESULTS
A total of 200,370 patients were included in the final analysis. Patients with CRS were significantly more likely to demonstrate a history of tobacco use than controls (19.6% vs. 15.0%) (p<0.001), with an adjusted odds ratio (aOR) of 1.42, 95% CI 1.37-1.47, (p<0.001). More patients with CRS and comorbid asthma used tobacco (19.5%) than controls with asthma (15.0%) (p<0.001).


CONCLUSION
History of tobacco use may portend increased risk for the development of CRS among patients undergoing ESS compared to healthy controls.
