The aim of the present study was to characterize the profile of victims of interpersonal physical violence (IPV) caused by a knife or other sharp instrument, identify the factors associated with maxillofacial trauma, and examine the incidence of maxillofacial trauma over time.
In a retrospective cohort study, we evaluated 569 medicolegal and social records of IPV victims by knife or other sharp instruments treated at a forensic medicine and dentistry center in Brazil during a 4-year consecutive period. The variables investigated were related to the sociodemographic characteristics of the victims, circumstances of the aggression, and trauma patterns. Descriptive and multivariate statistics through Poisson regression and trend analysis with the creation of polynomial regression models were used.
The cumulative incidence of oral-maxillofacial trauma was 19.3%. The mean age of the victims was 31.29 ± 13.82 years. Cases of trauma affecting more than one region of the face prevailed (45.5%). Based on the final Poisson regression model, unemployed people were more likely to exhibit maxillofacial trauma (relative risk [RR] 1.86; 95% confidence interval [CI] 1.03-3.35; P = .039). In addition, individuals were more likely to experience maxillofacial trauma on Wednesdays (RR 1.85; 95% CI 1.01-3.37; P = .045). The trend analysis revealed a significant increase in oral-maxillofacial injuries over time (P < .05).
The incidence of oral-maxillofacial trauma was high, and the main factors associated with trauma were the victim's employment status and day of occurrence. Future studies will focus on assessing the effect of maxillofacial trauma on the quality of life and well-being of violence victims.
本研究旨在描述由刀或其他锐器导致的人际身体暴力（IPV）受害者的特征，确定与颌面创伤相关的因素，并研究颌面创伤随时间的发生率。
在一项回顾性队列研究中，我们评估了巴西一家法医学和牙科中心连续4年期间治疗的569例因刀或其他锐器导致的IPV受害者的法医学和社会记录。所调查的变量与受害者的社会人口统计学特征、攻击情况和创伤模式有关。使用了通过泊松回归进行的描述性和多变量统计以及创建多项式回归模型的趋势分析。
口腔颌面创伤的累积发生率为19.3%。受害者的平均年龄为31.29±13.82岁。面部多个区域受影响的创伤病例占主导（45.5%）。基于最终的泊松回归模型，失业者更有可能出现颌面创伤（相对风险[RR]1.86；95%置信区间[CI]1.03 - 3.35；P = 0.039）。此外，个体在周三更有可能遭受颌面创伤（RR 1.85；95% CI 1.01 - 3.37；P = 0.045）。趋势分析显示口腔颌面损伤随时间显著增加（P < 0.05）。
口腔颌面创伤的发生率很高，与创伤相关的主要因素是受害者的就业状况和发生日期。未来的研究将集中于评估颌面创伤对暴力受害者生活质量和幸福感的影响。
