BACKGROUND/AIM: Road traffic accidents (RTAs) are a common cause of maxillofacial injuries. The aim of this retrospective multicentre study was to investigate the characteristics of maxillofacial fractures and dental injuries that occurred in RTAs in Miyagi, Japan.
The records of 404 patients with maxillofacial injuries treated at the Oral and Maxillofacial Surgery Departments of four different institutions over a period of 12 years were analysed. Ninety-nine of these patients had suffered these injuries in an RTA. RTA-related cases were divided according to age, gender, presentation month, presentation day of the week, transportation mode, time of accident, fracture sites and fracture mechanism.
There were 72 males and 27 females who suffered injuries as the result of an RTA, for a male-to-female ratio of 2.7:1.0, with a mean age of 35.3 years (range, 1-86 years old). Most of the accidents occurred in June and on a Wednesday, and most of the affected patients were riding a bicycle at the time. The number of patients with maxillofacial injuries related to bicycle riding showed an increasing trend in recent years. Mandible fractures were the most prevalent, followed by dental injuries and maxilla fractures. In cases with a single fracture of the mandible, the symphysis was the most frequent site, while in those with multiple fractures, the association of symphysis and bi-lateral condyle fractures was the greatest. For bicycle-related accidents, a single fracture in the mandible occurred more often than multiple fractures.
The number of RTA-related injuries while bicycle riding showed an increasing trend with mandible fractures commonly seen in those cases. Efforts to reduce maxillofacial injuries related to bicycle accidents are needed.
背景/目的：道路交通伤害（RTA）是颌面损伤的常见原因。本回顾性多中心研究的目的是调查日本宫城县 RTA 中发生的颌面骨折和牙损伤的特征。
分析了在四年间，四家不同机构的口腔颌面外科治疗的 404 例颌面损伤患者的记录。其中 99 例患者因 RTA 受伤。根据年龄、性别、就诊月份、就诊周几、交通方式、事故时间、骨折部位和骨折机制对 RTA 相关病例进行分类。
72 名男性和 27 名女性因 RTA 受伤，男女比例为 2.7:1.0，平均年龄为 35.3 岁（范围为 1-86 岁）。大多数事故发生在 6 月和星期三，大多数受伤患者当时正在骑自行车。近年来，与骑自行车相关的颌面损伤患者数量呈上升趋势。下颌骨骨折最为常见，其次是牙损伤和上颌骨骨折。在单一下颌骨骨折的病例中，颏部是最常见的部位，而在多发性骨折的病例中，联合颏部和双侧髁突骨折的情况最多。对于与自行车相关的事故，单一的下颌骨骨折比多发性骨折更为常见。
骑自行车相关的 RTA 受伤数量呈上升趋势，下颌骨骨折更为常见。需要努力减少与自行车事故相关的颌面损伤。
