title: Unsuspected penetrating maxillo-orbitocranial injury: a case report.
abstract: A healthy 37-year-old man presented to the emergency room, complaining of blunt trauma to his mandible from a tree branch. Plain radiographs and computed tomography demonstrated a penetrating orbitocranial foreign body with the maxillary sinus as the entry site. The foreign body was a chain-saw file. It was extracted successfully through the oral cavity. The patient's recovery was uncomplicated and he suffered no neurologic or opthalmic sequelae.
