Abstract
OBJECTIVES: Sinonasal inverted papillomas (SIP) present a potential for recurrence years after the surgery, but most studies report short-term follow-up, and risk factors for recurrence are still debated. Furthermore, several classifications are described, and no consensus exists regarding which one should be used. The aims of this study were to report our long-term results, investigate for potential risk factors for recurrence, and compare the existing 8 staging systems. METHODS: Over a 28-year period, 110 patients with a diagnosis of SIP were enrolled. The median follow-up time was 55.6 months. RESULTS: In multivariate Cox regression modeling, history of previous surgery was the only variable associated with recurrence (hazard ratio = 4.91, 95% CI, 1.80-13.39). Recurrences occurred up to 60 months after the surgery. Among the 8 staging systems, none proved to be associated with recurrence. CONCLUSION: The only factor associated with recurrence of SIP was prior surgery, probably corresponding to an incomplete initial resection. Due to late recurrences, an extended follow-up of at least 5 years is mandatory. In the absence of a classification predicting prognosis, Krouse's staging system should be used to homogenize studies' report since it is the most widely used.
