Treatment of inverted papilloma in the nasal and paranasal sinus: a clinical study of 36 cases

Abstract

Between April 2007 and March 2017, 36 patients （32 males, 4 females; average age, 63.8）with inverted papilloma （IP）in the nasal and paranasal sinus were treated. There were 6 patients in Krouse stage T1, 7 in T2, 20 in T3, and 3 in T4 （2 had malignant IP）. All T1 and T2 cases were treated by endoscopic surgery, and T3 and T4 cases were treated by either endoscopic surgery or lateral rhinotomy, or both. The observation period was 13-84 months and the recurrence rate was 19%. The aim of treating IP surgically is complete tumor resection, and it is important to follow up using rhino-fiberoscopy, CT, or MRI to detect early recurrence of IP.
