Correlation between Computed Tomography Staging and Quality of Life Instruments in Patients with Chronic Rhinosinusitis

Abstract

The scores on patient-based questionnaires such as the SNOT-20, SF-36, and VAS correlate with each other. The CT stage correlated weakly but significantly with the scores in the patient-based questionnaires only in the CRSwNP subgroup. The presence of nasal polyps was not associated with poor QoL in CRS patients.
