title: [Factors that affect the improvement of olfactory function after endoscopic sinus surgery in patients suffering from chronic sinusitis and/or nasal polyps].
abstract: 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.
