Dento-alveolar and maxillofacial injuries: a 5-year multi-center study. Part 2: severity and location

Maxillofacial and dental injuries are not uncommon. These injuries may cause morbidity and demand meticulously planned treatment. Part 1 of this study focused on the incidence of general trauma injuries, as well as facial or dental trauma. The aim of part 2 is to evaluate the severity and location of the dento-alveolar and maxillofacial injuries over 5 years. A retrospective cohort study was conducted based on data from the Israel National Trauma Registry. Patients admitted and hospitalized due to trauma injuries during the years 2000-2004, totaled 111,010 in which 5886 (5.3%) were maxillofacial or dental injuries. Most of these injuries were traffic-related (54.5%), followed by events at home (18.7%). Facial injuries combined with injuries to other organs involved occurred in 3721 (63.2%) of the patients. Most minor injuries were noted when no other organs were involved, while severe injuries were more common when multiple organs were involved. More than 25% of facial injuries required surgery. Meticulous epidemiologic studies are needed to support the leading role, extent, and severity of maxillofacial trauma.
