We analyzed the data of 39 patients who had undergone endoscopic sinus surgery for sinonasal inverted papilloma (IP) over the past 8 years and were followed up for half a year or more after the surgery. For this retrospective study performed in the 39 patients, we collected data from the medical records about the background characteristics of the patients, the follow-up period, about whether these patients had undergone the first operation or reoperation, the extent of the IP, the operative procedure, the recurrence rate, the interval to recurrence, and the site of recurrence.
There were 26 men and 13 women with an average age of 54.9 years, and the mean follow-up period was 30.44 months. The surgery was the first operation in 36 cases, and reoperation in 3 cases. The Krouse stage was 1 patient in stage T1, 11 in stage T2, 27 in stage T3 and 0 in stage T4. Of the 39 cases, 18 were treated by ESS with an additional endoscopic approach, and 1 patient was treated not only by ESS, but also by the Caldwell-Luc procedure. There were 2 cases with recurrence (5.13%). In one case, the recurrence occurred in the maxillary sinus 18 months after the operation, and in the other, the recurrence occurred in the ethmoid and frontal sinus at 12 months after the operation and at 30 months after the reoperation.
In order to further reduce the risk of recurrence, I think it would be useful to not only evaluate the origin of the IP before the operation, to remove the origin of the IP completely under clear endoscopic view by segmental resection, and scratch the bone thickening area, but also ensure a study of the margin, and not hesitate to perform expanded surgery in reoperation cases.
