摘要："Background/AimMandibular condylar fractures in pediatric patients may exhibit distinct epidemiological characteristics attributed to their unique growth and development phase, as well as various anatomical, physiological, biomechanical, and behavioral factors that differentiate them from adults. This study aimed to investigate the demographics, injurious factors, classifications, clinical manifestations, and treatments of pediatric mandibular condylar fractures, as well as the concomitant injuries in maxillofacial and other body parts.Materials and MethodsThis retrospective study analyzed the clinical data of 189 pediatric patients with mandibular condylar fractures between 2011 and 2022. Variables investigated included age, gender, timing of onset, causes, classification of condylar fracture, concomitant injuries, clinical manifestations, and treatment modalities.ResultsA total of 189 patients, a higher proportion of boys compared to girls was observed, with the highest incidence rate in children aged 1-3 years. They occurred primarily in July, June, and September as well as on Saturdays and Sundays. The most prevalent cause of mandibular condylar fractures was falls from heights in 73 patients (38.62%). Pediatric patients exhibited a higher susceptibility to condylar head fractures. A significant majority (81.48%) of these fractures were accompanied by soft tissue injuries in the maxillofacial region, with the chin being particularly vulnerable to injury. In addition, 61.90% of pediatric patients experienced fractures in other areas of the maxillofacial region, with the mandibular symphysis being the most commonly affected site. Dental trauma predominantly occurred in the anterior region (44.97%). Notably, a substantial proportion (28.04%) of cases also presented with multiple systemic injuries.ConclusionsThe characteristics of pediatric mandibular condylar fractures exhibit distinct features in terms of age, gender, timing of onset, etiology, location and type, the presence of concomitant maxillofacial soft/hard tissue injuries and multiple systemic injuries, as well as clinical manifestations and treatment modalities. Therefore, clinicians should pay special attention to the diagnosis and treatment of pediatric condylar fractures."
