Ossifying Fibroma of the Left Ethemoidal and Sphenoidal Sinus: A Case Report

Abstract

Ossifying fibroma (OF) is a rare benign lesions included in a heterogeneous group of bone disorders affecting
the craniofacial bones. We would like to report a case of a 10-year-old female with a cemento-ossifying fibroma
of the left sinonasal region, expanding into the orbit and causing proptosis of the left eye arising from sphenoid
sinus. Complete surgical resection via an endoscopic nasal approach was performed after a preoperative work-up
comprising head and neck computed tomography.
A review of the literature has revealed that treatment of this aggressive benign tumor must comprise of complete
surgical resection since it is notorious for recurrence. Patients with juvenile ossifying fibroma tumours require
long-term follow-up due to the high recurrence rate.
