Abstract

Background: Recurrence of inverted papilloma (IP) is a problem in 12-17% of tumors. Controversy exists regarding benefits of intraoperative frozen section histopathology (IFSH) for IP resection; however, to our knowledge, no study has specifically investigated this. IFSH for IP resection is the standard of care in our practice. We, therefore, reviewed our outcomes of using IFSH for IP resection. A secondary goal was to assess the reliability of IFSH. Methods: Patients with IP who underwent surgical resection (2010 -2016) with minimum 9-month follow-up were included. Results: Twenty-two adults with IP met inclusion criteria. All underwent surgery via endoscopic techniques, supplemented by external ports in five patients. At the time of presentation, 36% IPs were recurrent tumors; 68% were graded as Krouse stage 3. Resection was conducted until "clear" (negative) mucosal margins were achieved on IFSH. In 6 (27%), a "positive" IFSH result dictated additional resection to clear margins. Final negative margins were achieved in all the patients. Both positive and negative predictive values for IFSH were 100% (concordance with final pathology results). Surveillance was performed every 1-6 months with nasal endoscopy by using imaging when necessary. No recurrences were noted (0%) at mean follow-up of 40 months (range, 10-73 months). Conclusions: Positive IFSH results led to increased resection in 27% of the patients, with a 0% recurrence rate in this cohort. The reliability of IFSH for IP is very high. No recurrence of IP was noted in any patient at a mean follow-up of 3.3 years. IFSH may help reduce recurrence rates of IP, but additional studies with longer follow-up are warranted.
