The ossifying fibroma is a rare fibro-osseous benign lesion of bone in the head and neck region. The mandible is the most common site reported followed by maxilla and other bones of the skull. A paediatric male presented with protrusion of the right eyeball for one-month duration. Further evaluation by diagnostic nasal endoscopy revealed a smooth mass confined to the superior and middle meatus on the right side. Computed tomography of paranasal sinus showed a large heterogenous bony lesion involving the ethmoid and sphenoid sinus and extending laterally into the orbit and superiorly into anterior skull base. Endoscopic biopsy was suggestive of ossifying fibroma. Transnasal endoscopic excision of the lesion was done and the patient is currently on follow-up. This case is reported for the rarity of presentation and the difficulties in management.
骨化性纤维瘤是头颈部一种罕见的骨纤维性良性病变。下颌骨是最常报道的发病部位，其次是上颌骨和颅骨的其他部位。一名儿科男性患者出现右眼球突出1个月。通过诊断性鼻内镜进一步评估发现右侧中鼻道和上鼻道有一个光滑肿物。鼻窦计算机断层扫描显示一个大的不均匀骨质病变，累及筛窦和蝶窦，向外侧延伸至眼眶，向上延伸至前颅底。内镜活检提示为骨化性纤维瘤。对该病变进行了经鼻内镜切除，患者目前正在接受随访。报道此病例是因其表现罕见及管理上的困难。
