Aim. The objective of the present study was to describe the epidemiological characteristics of maxillofacial traumatic injuries in southern Brazil along a 5-year period.
Methods. The medical records of 173 patients with a total of 232 maxillofacial fractures were reviewed to collect information on patient age, sex, cause of fracture, anatomic location of fracture, duration of hospitalization, and treatment modality.
Results. Most fractures were caused by traffic accidents (31.2%), and patients belonging to age groups 21-30 and 31-40 years were most frequently affected. The male:female ratio was 6:1. The zygomatic-orbital complex was the anatomic region most frequently affected (47.8% of the 232 fractures), followed by the mandible (46.1%), maxilla (5.6%), and the naso-orbito-ethmoid complex (0.4%). Of the 173 patients, 55.5% were treated with open reduction with fixation, 23.1% with open reduction without fixation, and 20.2% with maxillomandibular fixation; in 1.2% of the cases, treatment modality was not informed. Most patients remained hospitalized for one to three days.
Conclusion. The findings of the present study revealed that, in southern Brazil, traffic accidents are the most frequent cause of severe maxillofacial injuries, affecting particularly the 21-40-year-old population. Prevention campaigns should be developed and implemented aimed at decreasing the number of trauma victims.
