The mandible is one of the most fractured bones in the maxillofacial region. We reviewed the 2007, 2011, and 2017 National Trauma Data Bank including 52,513 patients, making this the largest cohort analyzed. Variables of interest for this analysis include age, gender, race, mechanism of injury, fracture location, ICD 10 codes, laterality, open vs close, and concomitant fractures. Mechanism of injury includes assault, motor vehicle accident, fall, motorcycle and bicycle accidents, and firearms. The anatomic locations of interest were symphysis, ramus, condylar process, body, angle, coronoid process, and patterns of multiple fractures. Overall, mandibular fractures account for approximately 2% of all traumas reported. The most common age range of patients was 25-34 at 23.8% followed by 18-24 year-olds at 20.6%. Males were more commonly involved than females accounting for 78% of fractures. The mandibular body was most commonly fractured (19.2%) followed closely by the condyle (17.6%), angle (17.6%) and symphysis (17.2%). The most common mechanisms were assault (37%), followed by motor vehicle accidents (22%) and falls (20%). Compared to data from 2001-2005, there was a decrease in frequency of assaults (-5.6%) and motor vehicle accidents (-9.2%) and an increase in frequency of falls (+5%). Specifically, there was an increase in mandibular fractures secondary to falls in aging females (55-85 age groups). The results of this large retrospective study, that examined temporal trends in mechanisms and fracture patterns, may aid clinicians in diagnosis and inform public safety policies aimed at reducing these injuries.
