Subjects and MethodFWe conducted an analysis of 100 CRS patients who underwent endoscopic sinus surgery at the Department of Otorhinolaryngology of our hospital from October 2012 to March 2013. We measured nasal volume change and symptom change before and after the aspirin nasal provocation test (ANPT), and examined patient’s asthma history, allergy, Lund-Mackay score (LMS), total immunoglobulin E, peripheral eosinophil percentage, and objective measurement relapse.
ResultsFChronic rhinosinusitis patients with nasal polyps (CRSwNP) were more likely to have a positive ANPT test results compared to patients without nasal polyps (CRSsNP) (21.4% vs. 5.5%). ANPT (+) group had higher LMS and required more revision endoscopic sinus surgery than ANPT (-) group. These results were similar to those of CRSwNP compared with CRSsNP.
ConclusionF LMS and recurrence rates were higher in ANPT (+) compared to ANPT (-). Especially, recurrence rates were higher in ANPT (+) regardless of nasal polyp. Thus, careful endoscopic examination is required at follow up if CRS patients showed positive ANPT results.
