Maxillofacial Injuries in Tibet Region

目的:回顾性分析西藏地区颌面部损伤的临床流行病学特点。方法:对西藏军区总医院口腔科2001-06—2010-06间收治的588名颌面部创伤患者的病历资料进行回顾性研究。结果:颌面部损伤患者人数占本科住院总人数的26.4%,男女比例为4.8∶1,21～50岁为发病高峰年龄段,5～10月份为高发期。交通事故在致伤原因中居首位,占48.8%,其次是跌倒伤。颌面部损伤以单纯软组织损伤最为多见,占67.0%;颌面部骨折以下颌骨骨折最多见,占颌面部骨折总数的53.1%,下颌骨骨折的常见部位是颏部(43.1%);颅脑损伤是颌面损伤的常见合并伤。结论:男性青年为颌面损伤高发人群,交通事故是主要致伤原因,软组织损伤最多见,下颌骨为颌面部骨折的多发部位,颅脑伤为常见合并伤。

Objective： The purpose of this study was to analyze the epidemiologic features of maxillofacial injuries at a high altitude region in Tibet.Methods： An epidemiological retrospective study was statistically analyzed,with respect to gender,age,time distribution,causes,sites and type of fractures,accompanied injuries in 588 patients whom were treated from June 2001 to June 2010.Results： The incidence of maxillofacial injuries accounted for 26.4% of all in-patients,while the male to female ratio was 4.8∶1.Maxillofacial injuries appeared more frequently during May to October each year.The majority of patients were found between 21 and 50 years old.The most common cause of injury was traffic accident（48.8%）,and then followed by falling.The majority of patients（67.0%） were soft tissue injures.The bone fractures were frequently in the mandible（53.1%） while the most common site was the chin（43.1%）.Conclusions： Young men are mainly victims of maxillofacial injuries.Traffic accidents are the major cause of maxillofacial injures.Most of the injuries are soft tissue injures;mandible is the most commonly fracture site.The major accompanied injury,is brain injuries.
