Résumé
Inverted papilloma (IP) is a benign sinonasal tumor with a well-known propensity to recur, especially at its bony attachment site. Anecdotal evidence suggests lower rate of recurrence in primary resection. We also aimed to evaluate the effect of multifocal vs single focus of attachment in disease control. This work is a retrospective review of 535 IP resections performed during the period from 2006 to 2016 at a tertiary-care center. Demographic data, tumor location and attachment sites, and follow-up duration data were obtained. Two hundred ten patients were eligible for analysis. The mean age was 57 years, with an average postoperative surveillance of 36.4 months. Patients who had a previous procedure at an outside institution have a recurrence rate of 22.3%, compared with 12.4% for patients who had primary surgery at our institution. The most common site of attachment was maxillary sinus (47.6%), followed by ethmoid sinus (39%). Individual tumor review showed 50% of the patients to have multifocal attachment disease, of which there is a higher prevalence in secondary cases when compared with primary cases (53.7% vs 44.9%). Multiple tumor attachment sites had a significant effect on recurrence (odds ratio, 3.5; 95% confidence interval, 1.6-7.6; p = 0.002). Primary resection and single-focus attachment of inverted papilloma are associated with lower recurrence rates at 3-year follow-up.

BACKGROUND
Inverted papilloma (IP) is a benign sinonasal tumor with a well-known propensity to recur, especially at its bony attachment site. Anecdotal evidence suggests lower rate of recurrence in primary resection. We also aimed to evaluate the effect of multifocal vs single focus of attachment in disease control.
METHODS
This work is a retrospective review of 535 IP resections performed during the period from 2006 to 2016 at a tertiary-care center. Demographic data, tumor location and attachment sites, and follow-up duration data were obtained.
RESULTS
Two hundred ten patients were eligible for analysis. The mean age was 57 years, with an average postoperative surveillance of 36.4 months. Patients who had a previous procedure at an outside institution have a recurrence rate of 22.3%, compared with 12.4% for patients who had primary surgery at our institution. The most common site of attachment was maxillary sinus (47.6%), followed by ethmoid sinus (39%). Individual tumor review showed 50% of the patients to have multifocal attachment disease, of which there is a higher prevalence in secondary cases when compared with primary cases (53.7% vs 44.9%). Multiple tumor attachment sites had a significant effect on recurrence (odds ratio, 3.5; 95% confidence interval, 1.6-7.6; p = 0.002).
CONCLUSION
Primary resection and single-focus attachment of inverted papilloma are associated with lower recurrence rates at 3-year follow-up.
