Abstract：
Oral and maxillofacial trauma is influenced by various factors, including regional characteristics and social background. Due to the coronavirus disease 2019 (COVID-19) pandemic, a state of emergency was declared in Japan in March 2020. In this study, we aimed to examine the dynamics of patients with oral and maxillofacial trauma over a 12-years period using interrupted time-series (ITS) analysis. Patients were examined at the Shimane University Hospital, Maxillofacial Trauma Center from April 2012 to April 2023. In addition to general patient characteristics, data regarding the type of trauma and its treatment were obtained from 1203 patients (770 men and 433 women). Group comparisons showed significant differences in age, trauma status, method of treatment, referral source, route, and injury occasion. ITS analysis indicated significant changes in combined nasal fractures, non-invasive reduction, and sports injuries (P < 0.05), suggesting COVID-19 significantly impacted oral and maxillofacial trauma dynamics. A pandemic of an infectious disease may decrease the number of minor trauma cases but increase the number of injuries from outdoor activities, resulting in no overall change in the dynamics of the number of trauma patients. Medical systems for oral and maxillofacial trauma should be in place at all times, independent of infectious disease pandemics.
摘要：
口腔颌面部创伤受多种因素影响,包括地域特点和社会背景。由于2019年冠状病毒病(COVID-19)大流行，日本于2020年3月宣布进入紧急状态。在这项研究中,我们的目的是使用中断时间序列(ITS)分析,研究口腔颌面部创伤患者12年的动态.患者在岛根大学医院接受检查，颌面创伤中心2012年4月至2023年4月。除了一般的患者特征，我们从1203例患者(男性770例,女性433例)中获得了有关创伤类型及其治疗的数据.分组比较显示年龄差异显著，创伤状况,治疗方法,转介来源，路线,和受伤的场合。ITS分析显示合并鼻骨骨折有显著改变，非侵入性复位，运动损伤（P<0.05），提示COVID-19显著影响口腔颌面部创伤动力学。传染病的大流行可能会减少轻微创伤病例的数量，但会增加户外活动造成的伤害数量，导致创伤患者数量动态没有总体变化。口腔颌面部创伤医疗系统应随时到位，独立于传染病大流行。
