Background: Inverted-type Nasal Papilloma (PNI) and Sinonasal Polyposis (SNP) are benign nasal pathologies with similar symptoms and a complicated pre-surgical differential diagnosis. Tomography is only useful to determine the extension and plan a surgical approach.
Objective: To assess whether spike hyperostosis in the frontal sinus is a differential radiological marker between sinonasal polyposis and inverted nasal papilloma.
Material and Methods: Observational, cross-sectional, descriptive and retrospective study. In the Otorhinolaryngology service, UMAE 25, patients with a diagnosis of sinonasal polyposis and inverted nasal papilloma with frontal sinus involvement were included, patients with a diagnosis of sinonasal polyposis and inverted nasal papilloma were included, with histopathological result, the association of hyperostosis was evaluated spike with the diagnosis of inverted nasal papilloma, between January 01st, 2018 to June 01st, 2021.
Results: 76 patients included, 38 PNI, of which 23 (60.3%) presented spike hyperostosis, and 15 (39.5%) did not (OR 8.4, 95% CI, p<0.001). And 38 of PNS, of which 6 (15.4%) presented spike hyperostosis and 32 (84.6%) did not (OR 1.7, 95% CI, p=0.256).
Conclusion: hyperostosis could be associated as a differentiating factor between inverted nasal papilloma and sinonasal polyposis.
