Ossifying Fibroma of the Frontal Sinus: A Case Report and Literature Review.

Ossifying fibroma is a rare benign fibro-osseous tumor that rarely arises from the paranasal sinuses and tends to involve the frontal sinus more frequently than any other. Here, we report a case of a 32-year-old woman presenting with a 1.5-year history of facial pain on the right side of her eye along with proptosis. Radiographic findings revealed total opacification and bony changes in the right frontal sinus. The patient was treated with endoscopic sinus surgery for the purpose of performing a biopsy, followed by resection using the external approach. Ossifying fibroma was confirmed histologically. It is important to consider the possibility of ossifying fibroma when faced with a mass in the frontal sinus and that a radical excision is required for better results.
