BACKGROUND/AIM: One of the highest rates of car accidents and related morbidities and mortalities in the world is reported from Iran. Facial structures are usually injured in such accidents. This study is conducted to find the patterns and etiologies of mid-facial fractures in Iran.
During three consecutive years, patients with mid-facial fractures who were referred to a major oral and maxillofacial surgery center were studied for fracture etiologies and fracture locations.
Two-hundred and forty-three patients with mid-facial fractures were studied. Male-to-female ratio was 4.5-1. The average age of the patients was 31.7 years, but the 20-29 age group bears the highest rate of mid-facial fractures. Forty-four percent of fractures were related to automobile accidents, and 21% were attributed to motorcycle accidents. Other etiologies are 13.2% for collisions, 10.3% for falls, 6.2% for physical abuse, 2.9% for bicycle events, 1.6% for occupational events, and 0.8% for sport events. Most fractures occurred in zygoma followed by Le Fort and nasal bone fractures. More than half of all patients (80% of automobile and motorcycle accidents) were not either fastening the seat belt or wearing protective helmets.
The main etiology of mid-facial fractures is automobile and motorcycle accidents. Protective measures were not observed in the majority of patients.
背景/目的：伊朗报告的交通事故发生率及相关发病率和死亡率居世界之首。面部结构通常在这类事故中受伤。本研究旨在探寻伊朗发生的面中部骨折的类型和病因。
在连续三年的时间里，对被转诊至一家主要的口腔颌面外科中心的面中部骨折患者进行了骨折病因和骨折部位的研究。
共研究了 243 例面中部骨折患者。男女比例为 4.5:1。患者的平均年龄为 31.7 岁，但 20-29 岁年龄段的面中部骨折发生率最高。44%的骨折与汽车事故有关，21%归因于摩托车事故。其他病因包括碰撞占 13.2%，跌倒占 10.3%，身体虐待占 6.2%，自行车事故占 2.9%，职业事故占 1.6%，运动事故占 0.8%。大多数骨折发生在颧骨，其次是 Le Fort 和鼻骨骨折。超过一半的患者（80%的汽车和摩托车事故）既没有系安全带也没有戴头盔。
面中部骨折的主要病因是汽车和摩托车事故。大多数患者未采取防护措施。
