Abstract

The dermoid cyst is the one of common space occupying orbital lesion. This lesion is regarded as a non-invasive tumor, but infrequently causes destruction of adjacent bony structure and displacement of adjacent tissue. We experienced a characteristic ovoid orbital dermoid cyst that occupied in the frontal sinus and causes displacement of the eyeball with well-defined lining. This 55-year-old male presented a mass in left orbit, which rapidly increased in size for past 12 months, and patient could not open left eyelid. We removed this tumor totally then reconstructed the orbital roof and frontal sinus with an iliac bone graft and polyethylene sheet(Medpor Newnan, USA). This patient was followed up for 12 months and patient obtained satisfactory result without any complication suck as recurrence or infection.
