Background: Computed tomographic (CT) scan is important in the evaluation of chronic rhinosinusitis (CRS). The usefulness of CT scan in predicting the severity of symptoms is still debatable. The aim of this study is to determine the correlation between a CT scan scoring and the severity of clinical symptoms in patients with CRS. Methods: A cross-sectional study of patients with clinically diagnosed CRS. Their symptoms severity was assessed using the Sinonasal Outcome Test-20 (SNOT-20) scoring system. All eligible patients had CT scans using BrightSpeed (GE) computed tomographic scanner. The CT scan findings of each subject were scored according to the Lund-Mackay scoring system. The correlation between the CT score and the SNOT-20 symptom score was determined. Results: There were 120 participants comprised 70 (58.3%) males and 50 (41.7%) females with male: female ratio of 1.4:1. The mean and standard deviation of SNOT-20 were 38.9 ± 17.5 (range: 6–81) and that of Lund-Mackay score were 9.8 ± 5.5 (range: 0–24). There was statistical significant correlation between Lund-Mackay score and SNOT-20 score (r = 0.653 P = 0.000). The correlation was strongest in relation to nasal symptom domain (r = 0.746, P = 0.000), but it was weak with the facial symptom domain (r = 0.225, P = 0.013). Conclusion: This study found a strong positive correlation between the Lund-Mackay score and SNOT-20 symptoms score among patients with CRS.
