Measuring Success in the Treatment of Patients with Chronic Rhinosinusitis.

Chronic rhinosinusitis (CRS) has a substantial impact on patients' quality of life (QOL). Among the many metrics available for measuring treatment success in CRS, patient-reported outcome measures that quantify changes in QOL are the most widely used methods. In addition, objective data from imaging, endoscopy, and olfactory testing are useful adjunct measures to diagnose and prevent progression of disease, although these metrics have mixed correlations with symptoms and QOL. In the future, molecular biology, and multiomics techniques may change how successful CRS treatment is defined.
