title: Injuries associated with mandible fractures sustained in motor vehicle collisions.
abstract: Motor vehicle collisions are second only to altercations as the most common cause of mandible fractures. This article details in a retrospectively studied group the incidence of isolated mandible fractures and associated injuries in patients who were involved in motor vehicle collisions. This group consisted of 148 patients with mandible fractures listed in the University of Mississippi's trauma registry during the past 5 years. In almost all patients, associated injuries occurred with mandible fractures that were caused by motor vehicle collisions, with an incidence of 99.3 percent. Facial and head lacerations and facial fractures were the leading associated injuries, occurring in more than half of the patients who had a mandible fracture. Closed head injury is the major life-threatening associated injury and cause of mortality. The life-threatening injuries occurred in 64.8 percent of patients in this study. The mortality rate in this group of patients was 8.1 percent. These data suggest that mandible fractures from motor vehicle collisions should never be viewed as an isolated injury but rather as part of a spectrum of significant and sometimes life-threatening injuries that require thorough trauma evaluation at the time of presentation.
