Background: A number of factors are critical when considering the expected benefit of surgical intervention in patients with chronic rhinosinusitis (CRS) who have failed medical therapy. Objective: To evaluate the Sino-nasal Outcome Test (SNOT-22) and other patient demographic characteristics as predictors of postsurgical improvement in patients with CRS. Methods: Consecutive adult subjects presenting to the Otolaryngology Clinics at the University of Virginia with refractory CRS that required surgery were included. Patients were excluded if they had not completed both preoperative and postoperative SNOT-22 evaluations. Demographic and baseline measures, including asthma and smoking status, total immunuglobulin E (IgE), absolute eosinophil counts, and Lund-Mackay computed tomography (CT) scoring were also obtained for each subject. Regression analyses were performed. Results: One hundred four subjects met criteria and were included. These subjects showed a 51% overall improvement in postsurgical SNOT-22 evaluations (95% confidence interval [CI]: [45, 57%], P < .001). Multivariate regression analysis revealed that SNOT-22 items related to runny nose, cough, and sadness were independent predictors of postsurgical SNOT-22 improvement (P < .05, for all). Although runny nose had a direct correlation with improvement, more severe sadness and cough scores had a negative impact on degree of improvement. Similarly, analyses indicated that questions categorized as pertaining to nasal or ear symptoms were uniquely associated with postsurgical improvement in SNOT-22 scores (P < .001 and P = .015, respectively). Neither Lund-Mackay CT scoring, total IgE, nor absolute eosinophil counts correlated with improvement in postsurgical SNOT-22 scores. Conclusion: Physicians can use components of the SNOT-22 to predict likelihood of symptom improvement after surgical intervention in subjects with CRS.
