OBJECTIVE: To investigate the independent effect of hyperostosis on outcome after endoscopic sinus surgery (ESS) in patients with chronic rhinosinusitis (CRS). STUDY DESIGN AND SETTING: The medical records of 81 consecutive patients who had undergone primary ESS for CRS were reviewed retrospectively. Sinus CT scans were evaluated for the presence of hyperostosis to investigate the association with postoperative outcomes. The independent effect of hyperostosis on surgical outcome was analyzed, controlling for possible confounding factors with a multiple logistic regression model. RESULTS: Sixty percent of the patients showed hyperostosis, and there was a statistically significant association between the hyperostosis and postoperative outcome (P = 0.035, chi(2) test), which was confirmed after adjustment for the possible confounding factors (P = 0.048, odds ratio [OR] = 3.19, logistic regression analysis). CONCLUSIONS: Our study suggests that patients with CRS who have hyperostosis may have a poorer surgical outcome than those without hyperostosis. EBM RATING: B-2b.
