The purpose of this study was to evaluate the causes of blow-out fractures, the computed tomography findings, and the associated facial bone fractures in aged patients.
This study was performed by conducting a chart review. From January 2004 to December 2007, the patients who visited the emergency room of Asan Medical Center and were diagnosed as having a blow-out fracture were included in the study population. Patients 60 years of age or older were grouped as the aged group while patients younger than 60 years of age were grouped as the control group.
Between the aged group and the control group, there was a difference in the causes of blow-out fractures. The most common cause of blow-out fracture was a slip down in the aged group and violence in the control group (p<0.05). There were no differences in associated symptoms. Extraocular muscle herniation was the only statistically different computed tomography findings. In associated facial bone fractures, the most common fractures were the zygoma in the aged group and the nasal bone in the control group (p<0.05).
In patients 60 years of age or older, the most common cause of blow-out fracture was a slip down, and the most common associated facial bone fracture was a zygomatic fracture.
