To explore the preliminary application of three-dimensional (3D) printing technique in the operation of epidural hematoma.

Two cases of epidural hematoma in the Department of Neurosurgery, Yangxin County People’s Hospital of Binzhou City from January to September 2016 were selected to obtain the original data of brain CT scan. The three-dimensional model of epidural hematoma and the three-dimensional model of "armor" completely fitted to the head and facial tissues were made through Mimics 17.0 software. According to the projection of the epidural hematoma in the "armor" model, the scope of epidural hematoma is obtained, and the operative mold is obtained by 3D printing. The rational surgical incision was designed and the operation was performed. The effect of postoperative treatment was observed.

The operation has proved that the location of the epidural hematoma is accurate according to this method. After reexamination of CT hematoma, the removal of hematoma was more thorough and no delayed hemorrhage. The symptoms such as severe headache, disturbance of consciousness and hemiplegia before operation disappeared. After 6 months’ follow-up, the patients returned to normal life and social interaction, and the GOS score was 5 points.

For patients with epidural hematoma, the 3D printing technique was used before the operation, the accurate location of the epidural hematoma, the risk of operation, the rational surgical approach, the reduction of surgical trauma and the oppression of hematoma were selected. It is suitable for promotion in primary hospitals and junior doctors.
