ABSTRACT

Osteomas are benign tumors of membraneous bones, often arising in the calvaria or paranasal sinuses. Osteomas usually grow no larger than 2cm in diameter and are asymptomatic except when they interfere mechanically with joints, soft tissues, or with drainage of the paranasal sinuses. We have reported a giant osteoma in an adult having right eye protrusion and pain and interference of eye ball movements. The mass was totally removed by transcranial route successfully with no development of significant complications. The mass extremely hard and well circumscribed and enormous dimensions extended into right frontal, ethmoid sinuses, orbital cavity and root and nasal cavity.
