Abstract:
Objective:A displaced fracture in the anterior cranial base may be complicated by cerebrospinal fluid (CSF) rhinorrhea and enophthalmos. This study introduces a reconstruction technique with direct dural repair and reduction and fixation of the autologous fractured fragments.
Methods:Displaced fractures in the anterior cranial base were reconstructed using a stitching-up technique: A bicoronal scalp incision and frontal craniotomy was performed and the displaced bone was withdrawn. The lacerated dura was repaired primarily using a graft.Small holes were created in the intact cranial bones and the displaced harvest bone. Black silk was passed through the holes and the displaced bone was repositioned on tying the silk.Lumbar drain was not placed in any of the cases. The feasibility and outcome were evaluated.
Results:Five patients with displaced skull fractures of the anterior cranial base were included. All cases were men who had a direct impact on the forehead and/or eye. All the displaced fractures occurred in the orbital roof, and ethmoid bone fractures were present in 4 cases. Dural laceration was involved in 4 cases and repaired by placing artificial dura in 3 cases and a pericranial graft in 1 case. Following surgery, all cases were uneventful, and the anterior cranial fossa was well reconstructed. CSF leakage or enophthalmos did not occur in any of the cases.
Conclusion:Direct dural repair and autologous stitching-up reconstruction using the fractured fragment could be an effective method to prevent CSF leakage and enophthalmos in displaced fractures of the anterior cranial base.
