RESULTS: This study indicates a significant increase in the incidence of maxillofacial trauma in the region. There was a male predominance and the highest incidence was in the age group of 20-40 years. Road traffic accident was the most common aetiological factor causing maxillofacial trauma. More than 30% of trauma cases suffered fracture of maxillofacial skeleton. There was an increased incidence of midface fracture when compared to mandibular fractures in the study.
