摘要

Olfactory dysfunction is a common yet often overlooked symptom in patients with chronic rhinosinusitis (CRS). It significantly impacts quality of life, affecting nutrition, safety, and psychological well-being. Functional Endoscopic Sinus Surgery (FESS) is widely used for CRS refractory to medical therapy and may improve olfactory function. To evaluate olfactory function in CRS patients pre and post Functional Endoscopic Sinus Surgery (FESS). A prospective observational study evaluating subjective and objective olfactory function preoperatively and postoperatively using standardized olfactory tests. Olfactory dysfunction was observed in most CRS patients. Postoperative improvement was noted in a significant proportion, particularly in patients with nasal polyposis, though variability in outcomes was observed. FESS improves olfactory function in many CRS patients; however, outcomes depend on disease severity, duration, and mucosal damage. Routine olfactory assessment should be incorporated into CRS management.
