Minimally invasive endoscopic removal of a massive trabecular juvenile ossifying fibroma of the paranasal sinuses

An 11-year-old female patient presented with left-sided nasal obstruction and upward displacement of the left eye of 3 months duration. Clinical examination revealed a firm mass in the left nasal cavity. A CT scan showed a massive tumor involving the left maxillary sinus with extension into the ethmoid sinus, and encroaching on the left orbit. Histopathological examination revealed trabecular juvenile ossifying fibroma, which was removed via a transnasal endoscopic surgery by the Otorhinolaryngology, Head and Neck and the skull base team. She tolerated the lengthy procedure well, and there was no recurrence postoperatively as the tumor was resected completely. There was no external scarring and no psychological trauma discerned
