Abstract
Background: chronic rhinosinusitis (CRS) is a group of disorders characterized by inflammation of the mucosa of the nose and paranasal sinuses with a duration of at least 12 consecutive weeks. It is a common otorhinolaryngologic disease that is frequently encountered in everyday practice.
Aim of the Work: is to make a correlation between sinonasal outcome test-20 (SNOT-20) and Lund-Mackay radiological scoring system in patients with chronic rhinosinusitis.
Patients and Methods: 50 patients suffering from chronic rhinosinusitis and 50 normal persons were included in our study. The study and control groups were subjected to a questionnaire (SNOT 20) and the results were compared with the CT scan findings by Lund Mackay score to make a correlation between them.
Results: positive correlation was found between SNOT 20 score (symptoms) and Lund-Mackay score (CT scan), as SNOT 20 score was found to be directly proportional to Lund-Mackay score.
Conclusion: This study showed that there was a positive correlation between SNOT 20 score and Lund-Mackay score.
