BACKGROUND/AIM: Because bicyclists and motorcyclists with oral and maxillofacial injuries often suffer from disabilities requiring long-term treatment, reducing the severity of such injuries is a valuable objective for improving these people's quality of life (QOL). The aims of this study were, first, to present the prevalence and patterns of oral and maxillofacial injuries of bicyclists and motorcyclists and to compare the features of these injuries and, second, to determine the factors contributing to long-term hospitalization for these patients and to propose effective preventive measures.
This was a single-center retrospective analysis. Hospital records from 2011 through 2018 were reviewed for all patients who had sustained oral and maxillofacial injuries in bicycle or motorcycle collisions and had presented at a university hospital which was the only hospital in the region attended 24 hours per day by oral and maxillofacial surgeons. Characteristics of the oral and maxillofacial injuries, injury severity, and factors influencing the length of hospitalization were examined.
Records of 130 patients (82 bicyclists and 48 motorcyclists) with a mean age of 28.0 years were analyzed. Thirty-three patients (25.4%) had maxillofacial fractures, with 41 fracture lines while 103 patients (79.2%) had dental injuries and 57 patients (43.8%) had soft-tissue injuries. The distribution and prevalence of oral and maxillofacial injuries were similar for bicyclists and motorcyclists. However, motorcyclists had significantly higher Abbreviated Injury Scale (AIS) scores for facial injuries and the maximum AIS score than did bicyclists. According to a multiple regression analysis, the number of fracture lines and the requirement for intermaxillary fixation were independent factors influencing long-term hospitalization (standard regression coefficients: 6.795 and 6.715, respectively; P < .001).
The number of fracture lines and the use of intermaxillary fixation were independent factors influencing long-term hospitalization of both bicyclists and motorcyclists with oral and maxillofacial injuries.
背景/目的：由于口腔颌面部受伤的自行车和摩托车骑手经常患有需要长期治疗的残疾，因此减轻此类伤害的严重程度是提高这些人生活质量（QOL）的一个有价值的目标。本研究的目的首先是介绍自行车和摩托车骑手口腔颌面部受伤的发生率和模式，并比较这些损伤的特征，其次是确定导致这些患者长期住院的因素，并提出有效的预防措施。
这是一项单中心回顾性分析。对 2011 年至 2018 年期间因自行车或摩托车碰撞而导致口腔颌面部受伤并在该地区唯一一家 24 小时提供口腔颌面外科医生服务的大学医院就诊的所有患者的住院记录进行了回顾。检查了口腔颌面部损伤的特征、损伤严重程度以及影响住院时间的因素。
分析了 130 名患者（82 名自行车骑手和 48 名摩托车骑手）的记录，平均年龄为 28.0 岁。33 名患者（25.4%）有颌面骨折，有 41 条骨折线，103 名患者（79.2%）有牙损伤，57 名患者（43.8%）有软组织损伤。自行车骑手和摩托车骑手的口腔颌面部损伤分布和发生率相似。然而，摩托车骑手面部损伤和最大损伤严重度评分（AIS）的 AIS 评分明显高于自行车骑手。根据多元回归分析，骨折线数量和需要颌间固定是影响长期住院的独立因素（标准回归系数分别为 6.795 和 6.715；P<.001）。
骨折线数量和使用颌间固定是影响自行车和摩托车骑手口腔颌面部受伤长期住院的独立因素。
