Abstract: Objective To analyze the prevalence of chronic rhinosinusitis (CRS) with olfactory disorder and its influencing factors, so as to provide evidence for making corresponding intervention measures. Methods Adult patients with CRS were selected from a hospital in Fuxin City, Liaoning Province in 2018 to conduct a questionnaire survey, T&T olfactory function test, serum total immunoglobulin E (IgE) test, and Lund-Kennedy endoscopic scoring. Univariate and multivariate logistic regressions were used to analyze the influencing factors of CRS with dysosmia. Result sA total of, 340 patients with CRS were enrolled, with an average age of (45.73 ± 10.14) years. Of them, 45.88% aged 41-64 years, 65.00% were males, and 35.00% were females. The prevalence of CRS with olfactory disorder was 44.12%. Multivariate logistic regression showed that the positive serum total IgE level (OR=1.526), ??Lund-Kennedy scores≥2 (OR=2.813), previous nasal surgery history (OR=1.504), asthma (OR=1.870), nasal polyps (OR=2.139), and aspirin intolerance (OR=1.317) were independent risk factors for the prevalence of CRS with dysosmia. Conclusion The prevalence of CRS with olfactory disorder in Fuxin City, ??Liaoning Province was at a high level. The risk factors included asthma, history of nasal surgery, nasal polyps, aspirin intolerance, positive serum total IgE level, and Lund-Kennedy score≥2,it is recommended to take appropriate interventions to reduce the prevalence of CRS with dysosmia.
