초록

Background and Objectives: Sinonasal inverted papilloma (IP) is a benign tumor with a locally aggressive nature and a propensity to recur. Many risk factors for recurrence have been reported, but they are still controversial. The aim of this study was to comprehensively assess the demographic data, clinical features, and potential risk factors for recurrence of IP.Subjects and Method: This work is a retrospective review of 382 patients diagnosed with and treated for sinonasal inverted papilloma between 1986 and 2017 at a single tertiary medical center. Demographic data, presence of associated malignancy, information about previous surgeries, tumor location, Krouse stage, surgical approach, follow-up duration, and data on recurrence were obtained.Results: In our study, 31 of 382 cases (8.1%) were associated with malignancy. Mean age was significantly higher in patients with associated malignancy compared to the benign IP group. Of the 351 benign cases, 263 (74.9%) were primary, and 88 (25.1%) were revision cases (residual or recurrent disease). Although the proportion of patients with high Krouse stage or multifocal involvement was high in the revision cases, there was no significant difference in recurrence rate. The 226 patients with a minimum follow-up of 1 year were included for recurrence analysis. Recurrence rate was significantly higher in the conventional surgery group (17.4%) compared to that of the endoscopic and combined surgery groups (8.1% and 3.6%, respectively). Also, the recurrence group showed significantly larger proportion of patients with high Krouse stage and multifocal involvement.Conclusion: Risk factors for recurrence of IP found in this study are comparable to those previously published. Generally, the factors associated with recurrence of IP were prior surgery, clinical stage, involved site, and surgical approach. Therefore, surgeons should always consider these risk factors to reduce the chance of recurrence.
