对近五年来颌面创伤流行病学的研究进行综述，发现颌面创伤发病率约10.3%-32%，好发年龄为20—49岁，男性多于女性，但男女比例呈逐渐下降趋势。颌面创伤好发职业为农民。创伤好发时间为7、8、9月份。COVID-19流行造成的社会疏远期间，颌面创伤发病率降低，但损伤的严重程度更高。国内颌面创伤发生的主要原因是道路交通伤，其中因电动车造成的事故比例逐年上升。国外发达国家及一些低收入的欠发达国家主要原因是暴力打击伤。损伤类型以下颌骨骨折最常见。交通事故、工伤、跌倒坠落、暴力打击是下颌骨骨折的高危因素，年龄是其保护因素。颌面创伤合并全身常见损伤依次为，四肢、颅脑、胸部等 。颌面部骨折的最常用的治疗方法是ORIF。

Objective to review the epidemiology of maxillofacial trauma in recent five years. The results showed that the incidence rate of maxillofacial trauma was about 10.3%-32%, the age of onset was 20 - 49 years old, and the number of males and females was more than that of females. Maxillofacial trauma prone occupation for farmers. The most common time of trauma was July, August and September. The incidence rate of maxillofacial trauma decreased during the social alienation caused by COVID-19 epidemic, but the severity of injury was higher. The main cause of maxillofacial trauma in China is road traffic injury, and the proportion of accidents caused by electric vehicles is increasing year by year. 。 Foreign developed countries and some low-income less developed countries are mainly due to violence. Mandibular fracture is the most common type of injury. Traffic accidents, work-related injuries, falls and violent attacks are the high-risk factors of mandibular fractures, and age is the protective factor. Maxillofacial trauma combined with systemic common injuries were limbs, brain, chest, etc. ORIF is the most common treatment for maxillofacial fractures.
