Association of Sinonasal Computed Tomography Scores to Patient-Reported Outcome Measures: A Systematic Review and Meta-analysis

Objective To perform a systematic review of proposed sinus computed tomography (CT) scoring systems and determine their association with patient-reported outcome measures (PROMs). Data Sources PubMed, CINAHL, Scopus, and Cochrane Library. Review Methods A systematic search was conducted following the PRISMA guidelines (Preferred Reporting Items for Systematic Reviews and Meta-analyses) for studies describing CT scores and PROMs in patients with chronic rhinosinusitis. Results A total of 144 studies were included. Out of 20,741 patients, 53.6% were male and 55.5% had nasal polyposis. A meta-analysis of correlations revealed a moderate correlation between Lund-McKay (LM) and the 22-item Sinonasal Outcome Test (SNOT-22; r = 0.434, P < .001) and a weaker correlation between LM and the 20-item Sinonasal Outcome Test (SNOT-20; r = 0.257, P = .039). Meta-regression also revealed a weak association between LM and SNOT-20 (n = 25 studies) but no significant associations between Zinreich score and SNOT-22 or LM scores and PROMs, including SNOT-22 (n = 94 studies), Rhinosinusitis Disability Index (n = 25), nasal obstruction visual analog scale (n = 15), Chronic Sinusitis Survey (n = 12), Total Nasal Symptom Score (n = 4), Total Symptom Score (n = 3), and 12-Item Short Form Health Survey (n = 3). Conclusion There is essentially little association between radiologic grade and PROMs. CT grading systems with improved clinical utility are needed.
