The Impact of Gender on Long‐Term Quality of Life After Sinus Surgery for Chronic Rhinosinusitis

Abstract

ObjectiveTo identify the impact of gender on the clinical outcomes of endoscopic sinus surgery (ESS) through the comparison of quality of life measures in female and male patients who undergo surgical treatment for chronic rhinosinusitis (CRS).Study DesignProspective observational cohort study.MethodsPatients with CRS completed the 22‐item Sino‐Nasal Outcome Test (SNOT‐22) and EuroQol 5‐Dimension Survey (EQ‐5D) preoperatively and annually for 5 years following ESS. Health utility values (HUV) were calculated from EQ‐5D scores. Comparisons of cohort characteristics were performed with chi‐square and t‐tests. A multivariable linear mixed effects model evaluated changes in SNOT‐22 and HUV over time by gender.ResultsAmong the 1268 patients (54% female) enrolled, 789 and 343 completed postoperative surveys at one and 5 years, respectively. Preoperatively, females experienced more severe symptoms: mean SNOT‐22 score (51.1 ± 20.9 female vs. 44.7 ± 20.0 male, p < 0.001) and HUV (0.80 ± 0.14 female vs. 0.84 ± 0.11 male, p < 0.001). These gender differences were resolved by year one postoperatively (SNOT‐22: p = 0.083; HUV: p = 0.465). Two years after surgery, however, females reported more severe symptoms (SNOT‐22: 25.6 ± 20.7 female vs. 21.5 ± 17.4 male, p = 0.005; HUV: 0.88 ± 0.12 female vs. 0.90 ± 0.11 male, p = 0.018), a difference that persisted at year five. These gender‐related differences remained after adjusting for age, race, ethnicity, nasal polyps, history of prior ESS, and smoking status (p < 0.001). Within‐subject improvement was comparable between genders (SNOT‐22: p = 0.869; HUV: p = 0.611).ConclusionFemales with CRS reported more severe symptoms both before and 5 years after surgery compared to their male counterparts. Understanding the mechanism behind these gender‐related differences is important for optimizing CRS treatment.Level of Evidence2 Laryngoscope, 133:3319–3326, 2023
