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. Patients’ nasal endoscopic signs were recorded using Modified Lund–Kennedy scoring system before and 3 months after the surgery and radiological symptoms were recorded based on Lund–Mackay CT scoring before the surgery. Then the relationship between olfactory status and endoscopic and radiological findings was investigated.
Results
With respect to mean of olfactory score, a significant difference was observed before and after the surgery (p value = 0.001). There was a significant difference between means of pre- and post-operative endoscopy scores (p value = 0.001). Pre-operative endoscopic and CT scan scores had a negative correlation with pre- and post-operative olfactory scores (p value < 0.05). Pre-op. olfactory scores had negative correlation with post-op. endoscopy scores (p value = 0.02). Post-op. olfactory scores had negative correlation with post-op. endoscopy scores but was not statistically significant (p value = 0.22).
Conclusion
Our results revealed that pre-operative endoscopy and radiology findings were consistent with the olfactory status of patients with CRSwNP before and after endoscopic sinus surgery.
