Prevalence and characteristics of injuries to the head and orofacial region in physically abused children and adolescents--a retrospective study in a city of the Northeast of Brazil.

The aim of this study was to evaluate the prevalence and characteristics of injuries to the head and orofacial region in physically abused children and adolescents from a city of the Northeast of Brazil, based on the review of forensic medical reports. This retrospective study was undertaken by the analysis of expert medical reports derived from medical forensic exams performed at the Department of Forensic Medicine of the city of Campina Grande, PB, Brazil, between January 2003 and December 2006. From a universe of 11 624 reports issued in this time span, the study sample consisted of 1070 reports referring to children and adolescents aged 0-17 years that were confirmedly victims of physical abuse. Male children (52.8%) in the 13- to 17-year-old range (72.4%) were the most frequent victims, with an association between gender and age group (P = 0.039). Most children (58.2%) presented a single type of injury, with a statistically significant association between number of injuries and gender (P = 0.040), but no significant association between number of injuries and age (P = 0.163). The percentage of victims injured in the head and face corresponded to 56.3%, with a statistically significant association between the presence of injury in the head and face and gender (P = 0.046). As much as 12.4% of the children and adolescents presented intraoral injuries, with no significant difference between genders (P = 0.543). However, a statistically significant association was observed between the number of existing injuries and the presence of oral injuries (P = 0.005). The maxilla was predominantly affected (55.6%), most injuries (94.8%) being soft-tissue lacerations located mainly in the upper lip (46.4%). The findings of this survey revealed a high prevalence of injuries to the head and orofacial region of physically abused children and adolescents.
