Key clinical point: Superior turbinate eosinophilia is linked to olfactory decline in patients with chronic rhinosinusitis (CRS) after endoscopic sinus surgery.
Major finding: Patients with olfactory decline had significantly higher tissue, blood eosinophil levels, and TDI scores before surgery compared with patients with CRS who did not have any loss of smell.
Study details: A prospective study of 78 patients with CRS who underwent a smell test before and after endoscopic sinus surgery.
Disclosures: Dr. Wu reports no relevant conflicts of interest.
