A retrospective study was performed to assess facial fractures in patients treated at a public hospital in Belo Horizonte, in 2000. The data collected included age, gender, etiology, distribution of maxillofacial trauma considering day of the week and month, anatomic site of the fracture, and treatment. The analyses involved descriptive statistics and chi-squared test, Bonferroni test and analysis of variance. A total of 1,326 facial fractures were found in 911 patients. Most fractures occurred in adults with age ranging from 21 to 30 years. Men were more affected than women, with a male-female ratio of 4.69:1. Accidents causing facial fractures occurred predominantly on weekends. Bicycle and motorcycle accidents were the major cause of trauma, followed by interpersonal violence, automobile accidents, and falls. When the relation between the gender and the etiology of facial fractures was analyzed, a significant relation was noted between these variables (p < 0.001). There was also a relation between the patients' age and the site of the fractures (p = 0.0014). The mandible was found to be the most commonly fractured bone in the facial skeleton, followed by the zygomatic complex and the nose. A non-surgical approach was chosen in most cases. There were significant differences between the kind of treatment applied and the site of the fracture (p < 0.001).
2000年，在贝洛奥里藏特的一家公立医院对接受治疗的患者面部骨折情况进行了一项回顾性研究。收集的数据包括年龄、性别、病因、按星期和月份划分的颌面外伤分布情况、骨折的解剖部位以及治疗情况。分析涉及描述性统计、卡方检验、邦费罗尼检验和方差分析。在911名患者中总共发现了1326处面部骨折。大多数骨折发生在年龄在21至30岁的成年人中。男性比女性受影响更严重，男女比例为4.69:1。导致面部骨折的事故主要发生在周末。自行车和摩托车事故是外伤的主要原因，其次是人际暴力、汽车事故和跌倒。在分析面部骨折的性别与病因之间的关系时，注意到这些变量之间存在显著关系（p < 0.001）。患者年龄与骨折部位之间也存在关系（p = 0.0014）。发现下颌骨是面部骨骼中最常骨折的骨头，其次是颧骨复合体和鼻子。大多数情况下选择非手术方法。所采用的治疗方式与骨折部位之间存在显著差异（p < 0.001）。
