Precise localization and excision of the originating site of a sinonasal inverted papilloma is essential for decreasing tumor recurrence. In this study we evaluated the use of preoperative computed tomography (CT) to pinpoint the attachment/origi-nating sites of the tumor.

Sinonasal Inverted Papilloma

Objective To evaluate the correlation between the ability to predict the attachment site of sinonasal inverted papilloma by computed tomography and the long-term surgical outcome. Study Design Retrospective cohort study. Setting Five tertiary medical centers. Methods Study patients underwent attachment-oriented resection of inverted papilloma. The primary outcome was tumor recurrence. Results Among 195 patients eligible for the study, focal hyperostosis was recognized on computed tomography in 65% (n = 127), in 71% of primary cases (n = 101), and in 50% of revision procedures (n = 26). There was a trend for a higher incidence of squamous cell carcinoma among the patients without detectable hyperostosis ( P = .051). Location of hyperostosis coincided with the actual tumor attachment site in 114 patients (90%). Discordance between these parameters did not differ significantly ( P = .463) between 11 primary and 2 revision cases. The overall rate of recurrence was 9.7% (n = 19), with a mean time to recurrence of 20 months (range, 7-96 months). The rate of recurrence did not correlate with any of the following: tumor stage, surgical approach, presence of squamous cell carcinoma, whether the surgery was primary or revision, and the presence or location of focal hyperostosis on computed tomography. Inverted papilloma recurred significantly more often (38.5%) when the intraoperative findings of the tumor attachment site did not match the location of hyperostosis observed on computed tomography (odds ratio, 6.5; 95% CI, 1.78-23.66). Conclusion Detectability of focal hyperostosis on preoperative computed tomography does not affect the long-term outcome of inverted papilloma resection.

Abstract Objective To investigate the diagnostic performance of computed tomography (CT) to determine the origin, skull base involvement, and stage of sinonasal inverted papilloma (IP). Design This is a retrospective cohort study. Setting This is set at a tertiary care medical center. Participants Patients with preoperative CT imaging who underwent extirpative surgery for histologically confirmed sinonasal IP between January 2005 and October 2019. Main Outcome Measures The likely sites of tumor origin, skull base involvement, and radiographic tumor stage were determined by two board-certified neuroradiologists after re-reviewing preoperative CT imaging. These radiologic findings were then compared with intraoperative and pathologic findings. Results Of 86 patients, 74% (64/86) had IP lesions with correctly classified sites of origin on CT. CT was not sensitive for diagnosing ethmoid sinus origin (48%, 52%), frontal sinus origin (80%, 40%), and skull base origin (17%, 17%). CT was not sensitive (62%, 57%) but specific (86%, 98%) for identifying any skull base involvement. There was substantial-to-near perfect agreement between radiographic and pathologic Cannady stages (weighted κ = 0.61 for rater 1; weighted κ = 0.81 for rater 2). Interrater agreement was substantial for identifying tumor origin (κ = 0.75) and stage (weighted κ = 0.62) and moderate for identifying skull base involvement (κ = 0.43). Conclusion Interrater agreement on CT findings was substantial except on skull base involvement. CT correctly predicted site of tumor origin in up to 74% of subjects. CT was not sensitive for diagnosing skull base involvement but had substantial-to-near perfect agreement with pathologic tumor staging. CT is a useful but albeit limited adjunct for tumor localization and surgical planning for sinonasal IP.

The Relationship

ABSTRACT Sinonasal inverted papilloma is a benign neoplasm of epithelial origin, which represents 0.5 to 4% of all sinonasal tumors. Despite the histological benign nature of this type of tumor, it has a high rate of recurrence after surgical resection and significant malignant potential. Sinonasal inverted papilloma is treated as a locally aggressive tumor. The aggressive surgical approaches, such as en bloc resection via external excision or extensive mucosal stripping of the ipsilateral sinuses are replaced by less invasive intranasal endoscopic approaches. This creates a need for a very accurate preoperative assessment of the location of the tumor on computed tomography (CT) scan and identifies the location of the primary changes. Determination of the primary location of inverted papilloma is especially important for a radical resection of the tumor, because the tumor recurs mostly in the same location as the primary lesion. The aim of this study was to determine the relationship between changes in the preoperative CT scan of the paranasal sinuses and the location of papilloma by histological examination of surgical material. In this study, we evaluated the changes in the preoperative CT scans in the form of focal hyperostosis and erosion of the walls of the paranasal sinuses. Examined groups consisted of 12 people diagnosed with inverted papilloma and 15 peoples diagnosed with preinverted papilloma. Focal hyperostosis occurred in 83% of cases of inverted papilloma. Their location corresponded to 90% of the primal attachment of the tumor. Among the preinverted papillomas, focal hyperostosis occurred in less than 7% of the cases and did not correspond to the location of papilloma inverted. The analysis of remodeling and erosion of bone walls of the sinuses showed their presence in 67% of cases of inverted papilloma and 40% of cases of preinverted papilloma. However, their overlap with the location of the tumor was 50% for the inverted papilloma and 33% for the preinverted papilloma. Erosion and sinus bone destruction do not coincide closely with the primary location of the papilloma, because it is more the result of bone compression by the growing mass than bone invasion. The sites of focal hyperostosis closely coincide with the place of origin of the inverted papilloma, but the pathophysiological mechanism of this phenomenon is not fully understood. The relationship between the sites of focal hyperostosis and the location of the primary tumor can be used when planning surgery for accurate resection. How to cite this article Salwa A.
