Olfactory Outcomes of Dupilumab Treatment for Nasal Polyposis

Chronic Rhinosinusitis With Nasal Polyps | Olfactory Disorder

The study aims to investigate the olfactory TDI score (Threshold, Discrimination, Identification) using the Sniffin' sticks test for patients with chronic rhinosinusitis with nasal polyps (CRSwNP) on dupilumab. Twenty-seven adult patients will be followed up during the treatment with dupilumab on three visits to the Otolaryngology Clinic (Baseline, 3 months and 6 months).

The primary endpoint will be the TDI score. Nasal polyp score, Quality of Olfactory Disorders - negative symptoms (QOD-NS symptom scores), SNOT-22 will be secondary endpoints.
