Supplement 3.
Mandibular fracture pattern and treatment of pediatric patients 1–16 years of age. The number of patients is reported (n), and the percentage of the total number of patients admitted with mandibular fractures is given in parentheses. The number of cases with removal of osteosynthesis material is reported, and the percentage of the total number of patients that received osteosynthesis material is given in parentheses. IMF = intermaxillary fixation, ORIF = open reduction and internal fixation
