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.
