The clinical differences between patients with skull base and convexity fractures were retrospectively investigated in 324 patients, of whom 110 had suffered head injury resulting in skull fracture.These 110 patients were divided into the skull base and convexity groups.There were no significant differences between the groups with respect to sex, age, Glasgow Coma Scales, injury severity scores, pupilabnormalities, and outcomes.Automobile collisions were the most common causes in the skull base group, and falls in the convexity group.Traumatic Coma Data Bank diffuse 1 type injuries were more frequent in the skull base group and evacuated masses were more frequent in the convexity group.Multiple injuries, shock on admission, lower hemoglobin concentrations, and increased transfusion requirements were evident in the skull base group.Controlling for shock, the outcomes in the skull base group were favorable.Convexity fractures were usually associated with isolated severe head injuries and require brain protection therapy.Skull base fractures were caused by a significant force distributed over a large area of the body with a tendency to induce shock, and require a multidisciplinary approach to treatment.
