Aggressive juvenile ossifying fibroma of the ethmoid sinus with orbital and intracranial extension: A case report.

Background: Juvenile ossifying fibroma is a rare benign destructive lesion of nose and paranasal sinuses. It occurs in the craniofacial bones of children below 15 years of age. It is usually discovered in the mandible and maxilla and rarely in the paranasal sinuses.

Case Presentation: We present a case of a 15-year-old girl with extensive right ethmoid sinus juvenile ossifying fibroma with intracranial and orbital involvement that was managed endoscopically at our center followed by lateral rhinotomy and frontal craniotomy with reconstruction due to the aggressive nature and recurrence of the disease. Patient was followed up post operatively for 3 years and was found free of symptoms ever since.

Conclusion: In this case report we present our experience in managing this aggressive recurrent disease of juvenile ossifying fibroma which requires multiple endoscopic and open surgical procedures. Such pathology needs a close and long follow up due to the aggressive nature of this disease.
