title: Giant ethmoido-orbital osteoma presenting with dacryocystitis and metamorphopsia.
abstract: Osteoma is the most common benign neoplasm of the paranasal sinuses. Intraorbital extension is rare. Here we report a 16-year-old adolescent boy who presented with epiphora and pain in the medial canthal area. A computed tomographic scan revealed a bone density mass in the left ethmoid cavity extending into the adjacent orbit. The tumor was removed via endoscopic endonasal surgery. The pathologic evaluation was consistent with osteoma. After surgery, all complaints have been resolved and there was not any sign of recurrence in the computed tomographic scan.
