Methods Retrospective study on patients with consecutive, treatment‐naïve SNIPs at a tertiary referral center between 1999 and 2019. Results Overall, RR was 9.8% (10 of 102 patients), with 2 of 10 recurrences (20%) occurring after more than 5 years. Histopathological workup revealed synchronous malignancy in 2 of 102 patients (2%). Subgroup analysis revealed a significantly higher RR for SNIPs involving the frontal sinus (26.3% vs 6.0%, P = .02). No SNIPs primarily originating from the frontal sinus were observed. Conclusion Overall, RR of treatment‐naïve SNIPs is comparably low; however, long‐term follow‐up is mandatory due to late recurrences. Secondary involvement of the frontal sinus was identified as risk factor for recurrence. No SNIPs primarily originating from frontal sinus were observed. View on the web Inoreader.
