Abstract: Due to the unique stage of growth and development in children，children are quite distinct from the adults in anatomical structure，dentition and psychological condition. Maxillofacial fractures can cause facial deformity，mouth-opening limitations and malocclusion，which significantly affect patients′ quality of life. Hence，the diagnosis and treatment of pediatric maxillofacial fractures remain a clinical challenge and hotspot of research worldwide. Maxillofacial fractures are commonly seen in teenagers. Falls，road traffic accidents and sports-related injuries constitute the most frequent causes. In recent years，computer-aided surgery can provide accurate diagnosis and minimally invasive treatment for pediatric maxillofacial fractures. Surgeons have gradually turned to surgical treatment for pediatric maxillofacial fractures. Absorbable materials are preferred for fixation of maxillofacial fractures，which can reduce the complication of secondary facial deformity. Children require long-term follow-up to monitor further facial growth. Clinicians should pay attention to the psychological state of the children. Early intervention should be performed for children with severe trauma or psychological problems. This review summarizes the research progress in the epidemiology，diagnosis and management of pediatric maxillofacial fracture，as well as the accompanying psychological problems in children.
