| Abstract |
|
Osteoma is a slowly growing benign tumor which mainly grows on the mandible and in the paranasal sinuses of the craniofacial region. Embryological, inflammatory, and traumatic theories make up the etiological basis of osteoma, but is still unclear and yet to be studied. We can classify osteoma by morphology and pathology into eburnated, cancellous, and mixed type, of which eburnated type is relatively common.
Most osteomas accompany no symptoms, so they are often discovered accidentally by a radiological examination. They never develop into a malignant form, so that periodic observation is sufficient enough for management, but when they grow and invade intraorbitally or intracranially and then compress clinically important structures, need a surgical management, because of possibility of diplopia, exophthalmos, epiphora, blindness due to optic atrophy, mucocele, brain abscess, meningitis.
A 52-year-old man complaining of right eye pain, diplopia, and exophthalmos was diagnosed a 4.5x3.0x 2.0cm sized fronto-ethmoidal osteoma by means of a three dimensional computed tomography. We experienced a osteoma removal through bicoronal incision, and orbital reconstruction with both rib and calvarial bone graft, and received satisfying results after 1 year follow-up, thereby report this case with a short review of references. |
