Abstract

The purpose of this report is to describe our surgical experiences in the treatment of cerebral decompression with in situ floating resin cranioplasty. We included in this retrospective study 7 patients who underwent in situ floating resin cranioplasty for cerebral decompression between December 2006 and March 2008. Of these patients, 3 patients had traumatic brain injury, 3 cerebral infarction, and one subarachnoid hemorrhage due to aneurysmal rupture. In situ floating resin cranioplasty for cerebral decompression can reduce complications related to the absence of a bone flap and allow reconstruction by secondary cranioplasty without difficulty. Furthermore, it provides cerebral protection and selectively eliminates the need for secondary cranioplasty in elderly patients or patients who have experienced unfavorable outcome.

Intraoperative photographs. A : Photograph showing the resin implant about 1 mm thickness. B and C : The resin implant was designed about 5 mm larger than the outer table of craniotomy bone flap in order to do not sink the implant under craniectomy site. Resin implant was fixed loosely by silk stitches to move freely depend on brain swelling.
