Abstract:
Objective To evaluate the CT characteristics of osseous diversity in patients with sinonasal inverted papilloma (SIP) and to correlate these characteristics with the origins of tumors. Methods Sinonasal CT images of 28 patients were reviewed retrospectively to detect areas within which there was focal hyperastnsia. The correlation between the sites on the CT scans within which there was osseous diversity and the origin of the tumors in the surgery was analyzed. Results Surgical evaluation of 22 lesions with focal hyperostosis in CT images revealed that 20 of these lesions coincided with the actual origin of tumor. The focal hypernstosis on CT images corresponded to the actual tumor origin in 71.4% of cases. It denotes the origin of SIP could be predicted from the focal hyperostosis site. The origin of the other 2 cases were disaccored with the focal hypercstosis site, one case had the origin of uncinate process but hyperestosis of anterior middle turbinate, another case had the origin of superior turbinate but hyperostosis of uncinate process. Nine lesions of 28 patients had air sign, 21 lesions had bone absorption and destruction and 19 lesions had bone displacement in CT images. The pressure from tumor growth can induce varied bone destruction and displacement, the source of SIP can be estimated by the bone destruction site and displacement direction. Conclusions There has a relatively high concordance between the origin of the SIP and focal hyperostosis on CT, The source of SIP could be discerned indirectly by bone destruction and displacement, these conduce to asscss the disease before surgery and make peminent operation.
