Maxillofacial Trauma Resulting from Physical Violence against Older Adults: A4-year Study in a Brazilian Forensic Service

Abstract

Objective: To evaluate the prevalence of maxillofacial trauma resulting from physical violence against older adults, describe patterns and identify factors associated with its occurrence. Material and Methods: This is a cross-sectional study conducted from the assessment of 7,132 reports of victims of violence who sought a Brazilian Service of Forensic Medicine and Dentistry, during the period from January 2008 to December 2011. Descriptive statistics, Pearson's chi-test square test and Poisson's univariate and multivariate regression (with robust variance) were performed using SPSS software version 20.0. The significance level was set at p <0.05. Results: A total of 259 older adults suffered physical violence. The occurrence of maxillofacial trauma was observed in 42.9% of the sample. Lesions in soft tissue (90.1%) affecting more than one region of the face (40.4%) were the most frequent. The prevalence of maxillofacial trauma was more frequent among individuals older than 66 years (PR = 1.166; 95% CI = 0.865-1.572), males (PR = 1.119; 95% CI = 0.807-1.550), victims of violence occurred within the community (PR = 1.431; 95% CI = 0.951-2.153), during the night shift (PR = 1.226; 95% CI = 0.911-1.651) and weekends (PR = 1.279; 95% CI = 0.955-1.714) performed without using blunt instrument (PR = 1.311; 95% CI = 0.932-1.846). Conclusion: The prevalence of maxillofacial trauma resulting from physical violence against older adults was high and soft tissue lesions affecting more than one face region were predominant.

“…Several factors such as injury pattern and regional location of collisions may also affect the pattern of mortality. In addition, the majority of fatally injured victims do not arrive at hospital and die due to trauma prior to arrival [17].…”

“…One of the difficulties of working with secondary data lies in the fact that, in many situations, the incomplete recording of information prevents the faithful transcription of findings [9,11,17].…”

Injuries in the Maxillofacial Complex and Associated Factors in Brazilian Victims of Violence: A Cross-sectional Study

“…However, other studies have found that the proportion of maxillofacial injuries due to violence against older adults is increasing. 23,27 Therefore, it should be considered that the reduced number of cases of violence against older adults may be related to their greater difficulty in making a formal complaint or notification due to their debilitating physical and/or psychological conditions 23,27 , thus increasing underreported cases.…”

Case Report: Facial injury due to a firearm projectile in a Brazilian adolescent

“…Injuries to the face should not be seen only as a medical problem, but also social and economic 13,14 . The costs incurred in providing care to the victims by the health teams and the losses to the patient (loss of wages, permanent or transitory disabilities) can limit the social reintegration of the victims and their return to the labor market 13 .…”
