dc.description.abstractIntroduction: Olfactory loss in patients with chronic rhinosinusitis has been measured by different methods. However, the results have been variable, and it is not clear whether endoscopic sinus surgery significantly improves olfactory function. This study was performed to evaluate the influence of endoscopic sinus surgery on olfactory function in patients with chronic rhinosinusitis. Materials and Methods: In this prospective analytic study, 73 patients (mean age, 39.63آ±12.94 years) with a diagnosis of polyps and sinusitis during 2011 were studied. The olfaction test was performed with three solutions; one with no odor (water) and two with phenylethyl alcohol (50% and 90% dilution, respectively). The patients' olfaction state were graded as no olfaction, or low, moderate or good olfaction before and 1 and 3 months after surgery, and was given scores between 0 and 3 and evaluated quantitatively. Results: Right-side olfaction was improved in 68.5% and left side in 67.1% of patients. Mean olfaction score on the right and left side was significantly improved after surgery in comparison with basic scores (before and after on the right side: 0.95آ±0.88 and 2.02آ±1.04; before and after on the left side: 1.02آ±0.84 and 2.00آ±1.21; both P < 0.001). Improvement after surgery in cases with left- and right-side anosmia was 66.7% and 61.9%, in low olfaction was 82.3% and 72.7% and in moderate olfaction was 66.7% and 80%. Conclusion: In patients with rhinosinusitis, endoscopic sinus surgery has considerable effect in improving olfactory function.
