Results: the study included individuals divided into 104 cases and 110 controls, who reported no Sino nasal disease. Cronbach’s alpha was 0.939, while controls scored 0.943 suggesting good internal consistency within the SNOT-22 questionnaire. The SNOT scores for the cases and controls (median (IQR)) were 42.0(25, 58, 25) and 12.5(4, 31, 25) respectively and were compared using a Mann-Whitney test showing a statistically significant difference in the scores between two groups (p=0.000).
