Orbital osteoma

Osteoma (osteoma) is a benign tumor of bone tissue, which mainly occurs in the bones of the bone inside the membrane, and generally stops growing as the bones mature. It is structurally divided into ivory osteoma, cavernous osteoma and mixed osteoma. Orbital osteoma is mostly ivory osteoma. Osteoma is most commonly found in the craniofacial bone, and a considerable part comes from the sinuses. Orbital osteoma often occurs in the bone seam at the junction of sinus cartilage and membranous bone, and tumor growth invades the orbit. Osteoma grows rapidly in adolescence, and most of the patients consulted are middle-aged. Most osteomas in the orbital region originate from the sinuses without causing symptoms and signs related to the orbit. Frontal sinus osteoma is most likely to cause orbital symptoms, but the ethmoid sinus and maxillary sinus can also affect the orbit. Sphenoid sinus osteoma rarely produces orbital manifestations.
