Effective Second-Stage Surgery for Intraorbital Abscess Caused by Inverted Papilloma: A Case Report.

An intraorbital abscess is an urgent condition that can cause visual impairment and intracranial complications. Here, we reported an intraorbital abscess caused by a frontal sinus inverted papilloma. If an infection from a nasal or paranasal sinus tumor is suspected, treatment strategies vary depending on whether the tumor is benign or malignant. Additionally, if emergency drainage is required, an extra nasal or an intranasal approach or a combination of both is selected depending on the localization and extent of the abscess. In the present case, we first performed emergency surgery using a combination of extra nasal and intranasal approaches to improve visual function, drainage, and diagnosis. After the definitive diagnosis, we were able to control both diseases through a two-stage treatment, including surgery for radical treatment. Given the effectiveness of the two-stage treatment, it could be considered for managing intraorbital abscesses.
