Traumatic brain injury (TBI) is a brain injury caused by physical external forces on the head that leads to changes in the brain tissue. Epidemiologic studies help to identify the key opportunities for decreasing burden of TBI, cost-effective prevention and treatment of TBI. This study was conducted to investigate the epidemiology and radiologic findings of patients with traumatic brain injures who referred to emergency department in Iran. In this retrospective descriptive-analytic study, the data of patients (n=267) with TBI admitted to Emergency Department of Shahid Mohammadi hospital of Hormozgan University of Medical Sciences were considered during 2017 year. The administrative dataset of Shahid Mohammadi hospital was used in the current study. Mean of age for patients was 29.87 years and 228 patients (85.00%) were men and 39 patients (15.00%) were women. The most trauma was associated to road accidents (n=203, 67%), 58 cases (21.70%) for falling from heights, 4 cases (1.54%) for struggle and 2 cases (0.7%) for water injury. The data showed that 35 patients (13.10%) were dead due to trauma and 232 patients (86.90%) survived. The results showed that epidural hematoma (EDH) (n=79) and subarachnoid hemorrhage (SAH) (n=71) had most incidence. The results showed a significant relation between age and trauma mechanism (P<0.05), so that 58 patients <18 years of age injured from road accidents, while 133 patients 18-60 years of age injured form road accidents. In conclusion, the most common causes of TBI in Bandar Abbas are accidents that must be reduced by traffic rules and transport safety.
