A Case of Complete Protrusion of Eyeball Due to Orbital Emphysema

Orbital emphysema is a well-known concomitant of fracture of the paranasal sinuses involving the orbit. The important clinical distinction lies in the presence of proptosis. This is found in the variety of emphysema confined to the orbit without communication with the lids. The rise in intraorbital pressure, which occurs when air enters the orbit, causes the proptosis. Authors have recently experienced a rare case of complete protrusion of the eyeball caused by orbital emphysema after contusion on occipital area of skull due to fall-down in 10 month-old korean girl. The eyeball was completely exposed out of the lid margin. The case report is reviewed with the several literatures.
