- Abstract
Purpose: To explore the association between intraoperative surgical margin sampling by the frozen sections and recurrence in inverted papilloma surgery., Methods: A multicenter, retrospective study of patients who underwent attachment-oriented IP resection in four tertiary care medical centers with a minimal follow-up of 36 months., Results: The study included 220 surgeries with a mean follow-up period of 49 months (range 36-204). The endoscopic approach was used in all but 4 cases; 73% of procedures were primary. Overall recurrence was 10.45% (n = 23). Squamous cell carcinoma was found in 5 cases (2.2%). Intraoperative margin sampling was obtained in 145 cases. There was no difference in the recurrence rate between frozen section and no-frozen section groups (p = 0.44). Furthermore, margin sampling in various sites of tumor origin, in cases with concomitant nasal polyps (p = 0.53) and in revision cases (p = 0.08) showed no correlation with recurrence. In 26 cases when the surgery was extended following a positive frozen section, there was a significantly higher recurrence rate (OR = 6.94)., Conclusions: According to our results, intraoperative margin sampling did not affect the recurrence rate of IP, and therefore, its routine use should be questioned., (© 2021.
