Two-Stage Reconstructive Surgery of a Patient with Head Trauma Resulting in Extensive Cranial Bone and Dura Mater Loss Caused by Postoperative Infection

Abstract

After external decompression for a case of head trauma, epidural abscess formation resulted in extensive cranial bone and dura mater loss, for which two-stage reconstructive surgery was conducted. In the first operation, after thorough debridement of the infected wound, the dura mater was reconstructed using a bipedicle pericranial flap with posterior and anterior pedicles. After the infection had completely subsided, the second operation was performed, reconstructing the cranium with grafted outer-table calvarial bone and cutting bone to reposition an old zygomatic fracture. At this point, the pericranial flap used for dura mater reconstruction in the first operation became a satisfactory graft bed for the grafted bone. The postoperative course was satisfactory, and there was no cranial bone absorption after roughly 2 year, and a favorable shape has been maintained for an extremely satisfying result.
