We aimed to study the prevalence of orbital blowout fractures and evaluate the causes and the location of orbital cavity fractures. In this cross-sectional study, the medical records of all patients admitted with facial trauma were assessed, sociodemographic information as well as the aetiology of trauma extracted, and the computed tomographic images of the patients were reassessed. Location of orbital blowout fractures and the severity of orbital fractures were evaluated. A total of 203 cases had blowout fractures (175 male and 28 female patients with a mean (SD) age of 36 (16) years. Road traffic accidents (n = 139, 69%) were the most common cause of orbital blowout fractures. Falls (n=29, 14%) and assault (n=20, 10%) were the other causes of trauma to the orbital structure, which resulted in blowout fractures. The medial wall was the most commonly involved location (n=81, 40%) followed by orbital floor (n=64, 32%), the combination of medial wall and floor (n=36, 18%), medial wall and maxilloethmoidal strut combination (n=13, 6%), and all the three locations altogether (n=9, 4%). Most of the blow-out fractures had mild severity (n=107, 53%). There was a significant relation between the severity and location of the blowout fractures (p < 0.001).
