title: Clinical prognostic factors of chronic rhinosinusitis after endoscopic sinus surgery.
abstract: OBJECTIVE
  We aimed to determine the clinical prognostic factors of chronic rhinosinusitis after endoscopic sinus surgery (ESS) in order to better guide the management of patients.
  
  
  METHODS
  A total of 254 patients with chronic rhinosinusitis after ESS with a follow-up of 24 months were evaluated retrospectively. Clinical grouping, hyperplasia of the ethmoid bone, anatomic variations, allergy, polyps, previous sinonasal surgery and recurrent polyps were analyzed.
  
  
  RESULTS
  The success rates were 64.4 and 91.9% with and without hyperplasia of the ethmoid bone, 87.6 and 86.4% with and without anatomic variations, 67.9 and 92.0% with and without allergy, 81.0 and 94.0% with and without polyps, 72.8 and 93.6% with and without history of surgery and 52.3 and 94.3% with and without recurrent polyps. In logistic multiple regression analysis, allergy (p = 0.0002; estimate, -4.2094), nasal polyps (p = 0.0007; estimate, -3.6393) and history of surgery (p < 0.0001; estimate, -5.0938) were found to reach a statistically significant level.
  
  
  CONCLUSIONS
  We propose that allergy, polyps and history of surgery might be significant indicators of poor prognosis after ESS.
