Patients with CRSwNP report the loss of smell and taste as one
of the SNOT-22 symptoms “most affecting” their health.1

Furthermore, higher SNOT-22 scores may indicate an
increased risk for major depressive disorder.2

In patients with CRSwNP, key type 2 cytokines
(IL-4, IL-13, and IL-5) can damage the epithelial barrier,
which can increase type 2 inflammation.

Fill in the blanks by selecting from the options below.
Loss of smell in CRSwNP caused by polyps, congestion, and
edema is referred to as
