Pediatric mandibular fractures: Surgical management and outcomes in the deciduous, mixed and permanent dentitions

Abstract

AbstractBackground/AimMandibular fractures are the most frequent type of pediatric facial traumatic injury, but their treatment remains controversial. The aim of this retrospective study was to analyze the surgical treatment and long‐term outcomes of dentate mandibular fractures in children and adolescents.Material and MethodsPatients with mandibular fractures in the dentate area who were surgically treated in the period from January 1, 2001, to December 31, 2020, were included. The following data were collected: age, gender, cause and mechanism of injury, fracture site and type, associated maxillofacial fractures, the timing of surgical treatment, Facial Injury Severity Scale (FISS) score, surgical approach, number and thickness of plates, hospitalization stay and outcome. Patients were divided into three groups: deciduous (≤6 years, group A), mixed (7–12 years, group B), and permanent (13–18 years, group C) dentitions. Statistical analyses were performed using SPSS software.ResultsDuring the study 91 patients (male: female ratio, 3.8:1), 4 in group A, 12 in group B, and 75 in group C, with 65 single and 52 double fractures were included. An intraoral approach was used in 87% of patients. In group C, 90% of patients were treated with fixation schemes consistent with those suggested in the literature for adults, versus 75% in groups A and B. Median follow‐up time was 20 months. No tooth germ injury or facial asymmetry was observed and only six group C patients had post‐operative malocclusions. Hardware removal occurred in 22% of the patients.ConclusionsThis 20‐year retrospective study shows that open reduction and internal fixation of pediatric dentate mandibular fractures caused no tooth germ damage or disturbances of mandibular growth in any dentition stage. Internal fixation schemes were similar to those used for adults, although it was necessary to adapt hardware size and position according to tooth and patient age.
