Introduction: Mandibular fractures are one of the most common pediatric facial skeletal injuries. Increased understanding of the epidemiology of these injuries can informIntroduction: Mandibular fractures are one of the most common pediatric facial skeletal injuries. Increased understanding of the epidemiology of these injuries can inform treatment and improve outcomes. We aim to characterize the demographics and management of pediatric mandibular fractures.
Methods: The National Trauma Data Bank (NTDB) was queried from 2007 to 2015 for all patients 1-18 years with mandibular fractures. Patient demographics, injury characteristics, and treatment course were collected. Operative management was assessed via multivariate logistic regression.
Results: A total of 23,187 (73% male) pediatric patients with mandibular fractures were included. The average age for was 14.1 for males and 12.5 for females. The most common fracture locations were the condylar process (16%) and the symphysis (14%). Frequent concomitant injuries were open face wound (49%), closed skull base fracture (14%), and concussion (14%). The most common cause of injury was assault in males (20%) and motor vehicle accident (MVA) in females (32%). 47% of patients underwent fracture reduction during initial hospitalization with median time to procedure of 12.5 hours. After correcting for age, gender, and injury severity score, patients who were struck by an object/person were significantly more likely to have fracture reduction (OR: 1.60, 95% CI: 1.42-1.80). Patients who were pedestrians in MVAs were less likely to receive reduction (OR: 0.78, 95% CI: 0.66-0.91) on initial hospitalization.
Conclusion: Pediatric mandibular fractures have 2.7-fold higher incidence in boys, and often require fracture reduction, particularly if due to striking injury. This study is the largest and most comprehensive epidemiologic study of pediatric mandibular fractures in the US. treatment and improve outcomes. We aim to characterize the demographics and management of pediatric mandibular fractures.
