Autologous cranioplasty following decompressive craniectomy in the trauma setting

Abstract

Background. Decompressive craniectomy (DC) is an option for the treatment of increased intracranial pressure resulting from an acute neurological insult, including insults caused by trauma. When the brain swelling has receded, the skull is reconstructed with a wide choice of materials, each with its own advantages and disadvantages in terms of cost, cosmetic appearance, biocompatibility, implant strength and complication rate. Autologous cranioplasty (AC), where the patient's own bone flap is stored and reutilised, is common in many countries. No outcome studies have, however, been published on this technique for traumatic injuries. Methods. A retrospective study was conducted including all AC operations performed following DC due to traumatic brain injury. All operations were performed in one institution during a 4-year time period. Results were analysed for complication rates. Results. 44 cases were included. The mean time from craniotomy to cranioplasty was 86 (95% CI: 63–109) days. Complications severe enough to warrant readmission or further surgery were found in 13 cases (30%). No statistically significant predictor of complication from cranioplasty was detected. The complication rate was similar to published data on cranioplasty using artificial prosthetic materials. Conclusions. AC in the trauma setting is a valid treatment option with a complication rate that seems no worse than other alternatives.
