This study was performed to identify the characteristics of oral and maxillofacial injuries in children and determine factors influencing a treatment duration of more than 1 month using medical records.
This retrospective observational study reviewed medical records of 258 children (< 16 years of age) with maxillofacial trauma treated at a university hospital between 2011 and 2021. Patients with and without tooth fractures or dislocations were compared, and the prevalence of injuries was analyzed across three age groups (0-2, 3-5, ≥ 6 years). Long (> 1 month) and short (< 1 month) treatment durations were compared, and independent predictive factors for prolonged treatment were identified.
Tooth injuries were observed in 204 (79.1%) patients. Deciduous central incisors in the primary dentition and central incisors in the permanent dentition were the most commonly affected. Soft tissue injuries occurred in 165 (64.0%) patients, while maxillofacial fractures were present in 7 (2.7%). Tooth fractures significantly increased with age (p < 0.001), while dislocations showed no age-related differences. Logistic regression revealed that maxillofacial fractures, tooth fractures, and two or more dislocated teeth were independent predictors of prolonged treatment, with odds ratios of 14.666 (1.625-132.359), 2.411 (1.099-5.287), and 2.350 (1.208-4.570), respectively.
Maxillofacial fractures, multiple tooth dislocations, and tooth fractures were confirmed as key factors influencing longer treatment durations. These findings may assist in the early management of maxillofacial injuries and improve communication with pediatric patients and their families.
本研究旨在通过病历识别儿童口腔颌面部损伤的特征，并确定影响治疗时间超过1个月的因素。
这项回顾性观察研究回顾了2011年至2021年期间在一家大学医院接受治疗的258名（<16岁）颌面部创伤儿童的病历。比较有无牙齿骨折或脱位的患者，并分析三个年龄组（0 - 2岁、3 - 5岁、≥6岁）的损伤发生率。比较治疗时间长（>1个月）和短（<1个月）的情况，并确定延长治疗的独立预测因素。
204例（79.1%）患者观察到牙齿损伤。乳牙列中的乳中切牙和恒牙列中的中切牙是最常受影响的牙齿。165例（64.0%）患者发生软组织损伤，7例（2.7%）存在颌面部骨折。牙齿骨折随年龄显著增加（p<0.001），而脱位无年龄相关差异。逻辑回归显示，颌面部骨折、牙齿骨折和两颗或更多颗脱位牙齿是延长治疗的独立预测因素，比值比分别为14.666（1.625 - 132.359）、2.411（1.099 - 5.287）和2.350（1.208 - 4.570）。
颌面部骨折、多颗牙齿脱位和牙齿骨折被确认为影响治疗时间延长的关键因素。这些发现可能有助于颌面部损伤的早期管理，并改善与儿科患者及其家属的沟通。
