Abstract

This study examines the pattern of facial fractures in automotive collisions using the National Automotive Sampling System – Crashworthiness Data System. The database was examined for trends within collision and occupant descriptors among occupants sustaining facial fractures. Drivers and right front passengers were included in an analysis of frontal collisions. Side impacts were assessed separately by identifying occupants exposed to near and far side collisions. The distribution of facial bone fractures and injury sources were demonstrated for each impact configuration. Risk ratios were used to demonstrate the effects of restraint use and airbag deployment. Seatbelts were found to reduce the risk of sustaining a facial fracture by 74% in frontal impacts. Facial fractures are associated with severe impacts with a risk of 5% at a Delta-V of 40 km/h and 65 km/h for unbelted and belted occupants respectively.
