Abstract


CRS is an inflammation of the sinonasal mucosa. SNOT-22 is a questionnaire that assesses the life quality of CRS patients. MLK is a scoring system that uses nasal endoscopy. This study aims to analyze the correlation between complaints on SNOT-22 and endoscopy findings on MLK. This cross-sectional study was conducted at a tertiary hospital from January 2023 to December 2024. A total of 74 patients were included: 45 CRS with Nasal Polyps (CRSwNP) and 29 CRS without Nasal Polyps (CRSsNP). This study used Pearson’s statistical analysis to identify the correlation between SNOT-22 and MLK in CRS patients, more specifically in CRSwNP and CRSsNP with Spearman’s statistical analysis. There is a correlation between SNOT-22 and MLK in CRS with r=0.408, sig/p value 0.000<0.05; a correlation in CRSwNP with r=0.364, sig/p value 0.014<0.05; a correlation in CRSsNP with r=0.482, sig/p value 0.008<0.05; a correlation between SNOT-22 nasal phase and MLK in CRSwNP with r=0,876, sig/p value=0,000<0,05; and no correlation between SNOT-22 nasal phase and MLK in CRSsNP with r=0,345, sig/p value 0.066>0.05. There is a moderate correlation between SNOT-22 and MLK in CRS, a weak correlation in CRSwNP, a moderate correlation in CRSsNP, a very strong correlation between SNOT-22 nasal phase and MLK in CRSwNP, and no correlation between SNOT-22 nasal phase and MLK in CRSsNP.
