This article reviews the management of mandibular body fractures in young children. Treatment principles of this fracture type differ from that of adults due to concerns regarding mandibular growth processes and dentition development. The goal of this fracture treatment is to restore the underlying bony architecture to its preinjury position in a stable fashion as non-invasively as possible and with minimal residual esthetic and functional impairment. The management of mandibular body fractures in children depends on the fracture type and the stage of skeletal and dental development; treatment modalities range from conservative non-invasive, through closed reduction and immobilization methods to open reduction with internal fixation. Disruption of the periosteal envelope of the mandibular body may have an unpredictable effect on growth. Thus, if intervention is required closed reduction is favored.
