Adult patients with obesity (most recent value of BMI \u2265\u200930\u2009kg\/m<jats:sup>2<\/jats:sup>) were included and separated into two cohorts: one that underwent bariatric surgery (<jats:italic>n<\/jats:italic>\u2009=\u200953,454) and another that did not (<jats:italic>n<\/jats:italic>\u2009=\u200917,006,670). Patients in the two cohorts were matched by age, gender, race, tobacco use, and asthma and allergic rhinitis comorbidities. Outcomes analyzed included the incidence of CRS and FESS, identified by ICD\u201010 and CPT codes, respectively, within 2, 5, and 10\u2009years. Patients with outcomes prior to the follow\u2010up window were excluded.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Two years after surgery, patients with obesity who underwent bariatric surgery had a decreased risk of developing CRS, with a relative risk (RR) of 0.79 (95% CI: 0.70\u20130.88). The risk remained lower at 5\u2010 and 10\u2010year post\u2010surgery, with a RR of 0.79 (95% CI: 0.73\u20130.86) and 0.73 (CI: 0.68\u20130.79), respectively. For patients with obesity and CRS, undergoing bariatric surgery resulted in fewer FESS at 2, 5, and 10\u2009years after surgery, with a RR of 0.52 (95% CI: 0.35\u20130.79), 0.56 (95% CI: 0.42\u20130.76), and 0.50 (95% CI: 0.38\u20130.67), respectively.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>In patients with obesity, bariatric surgery is associated with a decreased incidence of CRS and fewer FESS.
