PURPOSE: The purpose of this study was to validate and compare treatment outcomes for endoscopic resection of sinonasal inverted papilloma (IP) with or without the use of a navigation system. MATERIALS AND METHODS: A total of 58 patients who underwent endoscopic resection of sinonasal inverted papilloma by a single surgeon from 2007 to 2016 at our institution were retrospectively reviewed. Depending on the use of the navigation system, subjects were divided into two groups: a conventional endoscopic resection group without navigation system (CER group) and a navigation-assisted endoscopic resection group (NER group). RESULTS: There were 24 patients (41.4%) in the CER group and 34 patients (58.6%) in the NER group. Treatment outcomes showed that navigation-assisted endoscopic resection was a more beneficial surgical technique than conventional endoscopic resection for sinonasal IP. Post-surgical recurrence was noted in seven cases (29.2%) in the CER group and two cases (5.9%) in the NER group. Accordingly, the recurrence rate was significantly less in the NER group compared to the CER group (p = 0.026). There were two cases of complications (8.3%) in the CER group comprising cerebrospinal fluid leak and periorbital fat exposure, while no complications were noted for the NER group (p = 0.167). CONCLUSION: This study demonstrated that navigation-assisted endoscopic removal of sinonasal IP is helpful for reducing recurrence and avoiding surgical complications. Therefore, navigation systems should be always considered when performing endoscopic removal of sinonasal IP.
