A three-year retrospective study of pediatric and adolescent oral and maxillofacial trauma and infections at emergency department in a tertiary care medical hospital.

Objectives: Pediatric and adolescent oral and maxillofacial trauma and infections differ significantly from adults in anatomy, development, and immunity, making diagnosis and treatment challenging. This study retrospectively evaluated the etiology, clinical features, and management of oral and maxillofacial trauma and infections among patients aged 3 to 15 years. Materials and Methods: A retrospective review was conducted of 824 pediatric and adolescent patients who presented to the emergency department of Pusan National University Yangsan Hospital from January 2022 to December 2024. Patients were categorized based on chief complaints into trauma, infection, or other conditions. Primary analyses focused on trauma and infections, and secondary analyses included etiology, diagnosis, treatment, and outcomes. Results: Trauma accounted for 742 cases (90.0%) and infections for 44 cases (5.3%). Boys (65.7%) outnumbered girls (34.3%), and school-aged children (6-11 years) were most frequently affected (56.5%). Lacerations (49.2%) and abrasions (34.1%) were the most common traumas, followed by dental trauma (31.0%) and facial fractures (5.0%). Among fractures, the mandibular condyle (35.1%) was most commonly involved. Most fractures were managed non-surgically (54.0%), while 30.0% required surgery. Infections were mainly odontogenic abscesses (44.7%), cellulitis (36.4%), and sialadenitis (15.9%). Abscesses were treated with incision and drainage (57.1%) or antibiotics (19.1%), with 23.8% requiring hospitalization. Conclusion: Trauma was the most frequent emergency cause in pediatric and adolescent patients, particularly among school-aged boys. Most cases were successfully managed with appropriate treatment. Early diagnosis and timely intervention are essential for favorable outcomes in pediatric maxillofacial emergencies.
