The relationship between endoscopic and radiologic findings and olfactory status of patients with chronic rhinosinusitis with nasal polyps before and after the endoscopic sinus surgery.

Introduction: This study was attempted to investigate the relationship between radiologic and endoscopic findings and pre- and post-operative olfactory scores in chronic rhinosinusitis with nasal polyps.

Materials And Methods: In this study, 40 patients aged 19-64 years with chronic rhinosinusitis with nasal polyps (CRSwNP) undergoing endoscopic sinus surgery were involved. The patients' olfactory status was evaluated using Smell Identification Test (Iran SIT) before and 3 months after the surgery.
