Analyzing the Cost of Autogenous Cranioplasty Versus Custom-Made Patient-Specific Alloplastic Cranioplasty

Abstract

PURPOSE: Comparing expenses related to autogenous cranial vault reconstruction versus custom-made patient-specific alloplastic cranioplasty. METHODS: The authors retrospectively reviewed charts of a group of patients who underwent autogenous cranioplasty and poly-ether-ether ketone (PEEK) cranioplasty. The data collected from the patient files included demographic information, details of the surgery, postoperative recovery data, and also duration of surgery. The authors also added costs related to the length of surgery, utilization of intensive care unit, length of hospital stay, amount and seriousness of complications, and hardware cost. The outcomes were studied in terms of skull form maintenance and complications.Eleven of our patients had PEEK cranioplasty at Sunnybrook Hospital, Toronto, ON, in the period from July 2009 to June 2011. The authors identified 11 patients who had split skull autogenous bone graft cranioplasty. They were matched for age and skull defect size.Comparable information was collected for both patient groups. The information was examined to compare costs of custom-made patient-specific alloplastic implants and costs of autogenous cranioplasty. RESULTS: Conclusions made from this paper will hopefully serve as guidance for allocation of hospital funding and resources at the Ministry of Health level.
