Determine the behavior of the maxillofacial trauma of adults treated in 3 tertiary care centers in the central zone of Chile.
descriptive, cross-sectional, multicenter study, based on the prospective records of maxillofacial trauma cases attended between May 2016 and April 2017 by dental and maxillofacial clinical teams of Adult Emergency Units of hospitals Dr. Sótero del Río (metropolitan region), Carlos Van Buren and Dr. Gustavo Fricke (region V). Age, sex, date of occurrence, type of trauma according to ICD-10, etiology, legal medical prognosis and associated injuries were recorded, stratifying by sex and age. Chi square and unpaired Wilcoxon tests were used to compare by groups.
2.485 cases and 3.285 injuries were investigated. The male: female ratio was 1.7: 1 with age under 30 predominant, followed by older adults. Variability was observed in the yearly, weekly and daily presentation. The highest frequencies were in January and September, weekends and at night. The main etiologies were violence (42.3%), falls (13.1%) and road traffic crashes (12.9%) with differences by age and sex (p <0.05). 31,9% of the injuries occurred in hard tissue, being fractures in nasal bones predominant (S02.2).
the profile of the maxillofacial trauma in Chile seems to be mixed by age, affecting young people and the elderly. The male sex predominates; the main cause, which varies by age group, is violence. Their surveillance is possible from hospital emergency records.
确定在智利中部三个三级护理中心接受治疗的成人颌面创伤的行为。
这是一项描述性、横断面、多中心研究，基于 2016 年 5 月至 2017 年 4 月期间，由 Dr. Sótero del Río（大都会地区）、Carlos Van Buren 和 Dr. Gustavo Fricke（地区 V）成人急诊病房的牙科和颌面临床团队对颌面创伤病例的前瞻性记录。记录了年龄、性别、发病日期、根据 ICD-10 分类的创伤类型、病因、法律医学预后和相关损伤，并按性别和年龄进行分层。采用卡方检验和非配对 Wilcoxon 检验比较组间差异。
共调查了 2485 例病例和 3285 处损伤。男女比例为 1.7:1，以 30 岁以下人群为主，其次是老年人。每年、每周和每天的就诊情况存在差异。1 月和 9 月、周末和夜间就诊频率最高。主要病因是暴力（42.3%）、跌倒（13.1%）和道路交通碰撞（12.9%），且因年龄和性别而异（p<0.05）。31.9%的损伤发生在硬组织，以鼻骨骨折为主（S02.2）。
智利颌面创伤的特征似乎因年龄而异，影响年轻人和老年人。男性居多；主要病因因年龄组而异，为暴力。可以从医院急诊记录中监测到这些创伤。
