[Factors that affect the improvement of olfactory function after endoscopic sinus surgery in patients suffering from chronic sinusitis and/or nasal polyps].
OBJECTIVE
To investigate the factors related to the improvement of olfaction after endoscopic sinus surgery (ESS) in chronic sinusitis and/or nasal polyps patients.


METHODS
Fourteen patients suffering from chronic sinusitis and/or nasal polyps were accompanied with olfactory dysfunction. At 6 months after the ESS, measurement of olfaction showed that 27 patients' olfaction had improved. The effective rate is 61.36%. Using a logistic regression model, we analyzed the factors such as gender, disease stage, disease site, allergy, duration of olfactory dysfunction and follow-up.


RESULTS
Contrary to gender, disease site and duration of olfactory dysfunction, disease stage, allergy and follow-up had a significant effect on the improvement of olfaction.


CONCLUSIONS
In order to improve the olfaction of the patients with chronic sinusitis and/or nasal polyps, it is important to treat positively with allergic rhinitis on a basis of the ESS. Follow-up should be emphasized further.
