Postoperative steroid treatment for eosinophilic-type sinonasal polyposis.

associated asthma or ASA intolerance treated post-operatively with local nasal and oral steroids warrants further investigation in larger, prospective series. Objective: A high recurrence rate after functional endoscopic sinus surgery (FESS) has been widely reported in patients with eosinophilic-type chronic rhinosinusitis with nasal polyps (CRSwNP). This study compared the influence of two post-operative medical treatments – local nasal steroids alone vs local nasal and oral steroids – on the recurrence of eosinophilic-type CRSwNP. Method: Between January 2009–December 2010, 32 patients with eosinophilic-type CRSwNP received local steroid nasal therapy after FESS (Group A); from January 2011 onwards, another 28 patients were treated post-operatively with the same nasal treatment plus two cycles a year of oral steroids (Group B). All patients in both groups had a follow-up of at least 36 months. Results: Groups A and B did not differ significantly in recurrence rate (31.25% vs 32.14%, p = 1) or disease-free interval (p = 0.91), but Group B patients who were asthmatic or ASA-intolerant had a significantly lower recurrence rate than Group A patients with asthma or ASA intolerance (p = 0.04 and p = 0.004, respectively).
