Abstract

Ossifying fibroma, a rare tumor entity, is a well-demarcated benign fibrous-osseous tumor composed of bone, fibrous tissue, and cementum. It is commonly found in the mandible, but also found in the maxilla and paranasal sinuses. Simple curettage is enough when the fibrous lesions are located in the mandible; however, complete en bloc excision is required in the maxilla and paransal sinuses to relieve symptoms and to prevent recurrence. With the advent of sinonasal endoscopy in the mid-1980s and subsequent advances in surgical techniques, endoscopic management of the fibrous-osseous lesions has become feasible. We experienced a successful removal of the huge ossifying fibroma which occupied right ethmoid sinus and nasal cavity by endoscopic approach.
