Abstract

Background: After endoscopic sinus surgery (ESS), endoscopy is used to gauge surgical success and clinical outcomes. Prior studies have not examined this topic prospectively using validated outcome metrics across multiple institutions. Methods: A multi-institutional, prospective study of patients with chronic rhinosinusitis (CRS) who underwent ESS completed the 22-item Sino-Nasal Outcome Test (SNOT-22), missed productivity, and medication usage questionnaires 6 months postoperatively. Lund-Kennedy endoscopy scoring (LKES) was performed with reviewers blinded to patient-reported data. A control cohort of non-CRS patients was recruited for comparison. Results: Complete data was available on 183 CRS patients and 48 non-CRS control patients. Approximately 50% of patients achieve perfect or near perfect endoscopy (LKES 0 to 2) after ESS. Postoperative endoscopy correlated with total SNOT-22 scores (r = 0.278, p <0.001), with the strongest correlations to rhinologic and extranasal subdomains in the nasal polyp cohort. Improved postoperative endoscopy was associated with decreased antibiotic and oral steroid usage, but had little association with missed productivity. Among patients who achieved near perfect postoperative endoscopy, those with nasal polyps had SNOT-22 scores that were similar to non-CRS control patients (mean SNOT-22 scores 17.7 and 16.3, respectively). However, CRS patients without nasal polyps remained more symptomatic than non-CRS controls and CRS with nasal polyps patients despite nearly perfect endoscopy (mean SNOT-22 score 21.6). Conclusion: Postoperative endoscopy correlates with SNOT-22 and medication usage in CRS patients. Polyp patients who achieve near perfect endoscopy have similar symptoms to healthy controls; however, nonpolyp patients with near perfect endoscopy still have rhinologic and extranasal symptoms that are worse than healthy controls.
