Craniofacial resection of ossifying fibromas and osteomas of the sinuses.

Massive fibro-osseous lesions of the frontal and ethmoidal sinuses are rare. If left untreated, these lesions can produce chronic infection, orbital complications, and/or intracranial events. In the past, resection of these lesions has usually been subtotal and a risk of damage to intracranial structures existed, particularly to the dura, due to poor exposure, and a high recurrence rate was also present. We have treated eight such lesions with a combined craniofacial approach for total resection with resolution of symptoms, without recurrence, and without occurrence of cerebrospinal fluid leak, damage to the orbital contents or intracranial structures, or resultant cosmetic deformity.
