Abstract： Objective To evaluate the efficacy of various nasal endoscopic surgery for sinonasal inverted papilloma (SIP).Methods Complete follow-up data of 58 cases of sinonasal inverted papilloma were retrospectively analyzed.Patient types as well as Krouse staging and rates of recurrence with various surgery were statistically analyzed.Results During the follow-up for (68±3) months, SIP recurred in 6 cases.The rate of recurrence was 9.8% (4/41) in cases with primary diagnosis vs 11.8% (2/17) in those with relapsing tumors, respectively.Recurrence rates with stages Ⅰ , Ⅱ , Ⅲ and Ⅳ tumors were 11.1% (1/9),6.7% (2/30), 6.7% (1/15) and 50.0% (2/4) respectively.For simple nasal endoscopic surgery, endoscopyassisted Caldwell-Luc's surgery, and endoscopy-assisted lateral rhinotomy, the recurrence rates were 15.6% (5/32) , 4.2% (1/24) and 0 (0/2), respectively.There was no significant difference among patient types,Krouse staging or surgical methods.Conclusions Nasal endoscopic surgery is a safe, effective and minimally invasive method for sinonasal inverted papilloma.Selection of endoscopic surgery according to patient type and stage is critical for a successful treatment.
