Abstract

Objectives: To correlate between computed tomography and nasal endoscopic findings in patients of chronic rhinosinusitis (as per RSTF symptom criteria).

Study design: Cross-sectional study.

Materials and methods: All adult patients presenting for evaluation of Chronic Rhinosinusitis were studied with the use of the rhinosinusitis symptom inventory (RSI), nasal endoscopy, and sinus computed tomography (CT). We determined sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) between scores for symptoms, endoscopy, and CT.

Results: A total of 78 patients were studied with the use of the rhinosinusitis symptom inventory and then data were analysed. For endoscopy, after taking CT scan as gold standard, sensitivity, specificity, positive predictive value, and negative predictive value were calculated as 92.7, 91.3, 96.2, and 84 percent with likelihood ratio 55.59 (p=.000).

Conclusion: In CRS patients, for decision making, Endoscopy and CT scores correlate well with each other but not so well with the symptom score.
