The aim of this study was to discuss the significance of microplate osteosynthesis in pediatric mandibular fractures. Patient and methods: Ten patients with age ranged between 1-10 years were collected from those attending the outpatient clinic of Oral and Maxillofacial Surgery Department, Al- kawait Hospital, Sana’a University. All patients that have mandibular trauma associated with either single or multiple fracture lines in the mandible were included in this study. Diagnosis of the mandibular fracture was achieved through history, clinical and radiographic examinations. All patients were treated by open reduction and internal fixation by 1.2mm microplate. Results: No signs of infection in or around the incision during fracture treatment were observed, and the soft tissue healing progressed normally. Clinical follow up was done every other day for two weeks and after three months postoperatively. Conclusion: Management of mandibular fracture in children by open reduction and microplate is an acceptable method for treatment with least morbidity and increase stability of displaced segment.
