title: Orbital emphysema following remote skull trauma.
abstract: In an unusual case of orbital emphysema following nose blowing, a reliable patient history and examination demonstrated no direct trauma to the orbit. Blunt posterior skull trauma was sustained several hours before the development of the orbital emphysema. A "seismic" transmittal of force to the orbital walls is postulated.
