Focal Hyperostosis of an Intranasal Inverted Papilloma Observed on Computed Tomography

Abstract

A 71-year-old woman presented to the clinic with a 1-year history of chronic nasal obstruction. She denied any history of underlying systemic disease or previous sinus surgery. Nasal endoscopy showed two large papillomatous lesions obstructing the left middle meatus and sphenoethmoidal recess. Under the suspicion of an inverted papilloma, the lesions were biopsied at our outpatient office, confirming the diagnosis. Computed tomography (CT) of the sinus was performed, revealing soft-tissue densities occupying the sphenoethmoid recess and the frontal, anterior, and posterior ethmoid sinus on the left side. Two focal hyperostosis lesions were observed in the lower portion of the left anterior ethmoid sinus (figure 1, A) and a A

A Systematic Review of Definitive Treatment for Inverted Papilloma Attachment Site and Associations With Recurrence

“…Many sites of IP attachment are associated with hyperostosis, indicating a proclivity for infiltration into the bone below the attachment site. 14,15,38 Surgeons are trained to recognize this feature of abnormal bone growth and sinus wall thickening on preoperative imaging and can tailor their surgical approaches to address this. Therefore, it is possible that drilling is the most commonly used technique in this review because it is the ideal approach to allow for more extensive bony removal in cases of hyperostosis and it has an increased depth of penetration when compared with cauterization alone.…”

An Inverted Papilloma Arising From the Basal Lamella of the Middle Turbinate: An Endoscopic View

“…Identification of the origin of an IP is important for the complete extirpation of such tumors. 4 Drilling, cauterizing, or completely excising the bone underlying the tumor base during endoscopic resection reduces the recurrence rate of IP. 5 In this case, the origin site of the polypoid mass was cauterized with suction cautery to prevent recurrence of the mass, even without the diagnosis of IP.…”
