The left-hand column specifies the parameters that were evaluated on each prosthesis. This type of cranial vault reconstruction requires little trans-operative adjustment time, since most adjustments are done pre-operatively, and the prosthesis adapts precisely to the defect (this was measured by tracing the prosthesis and its adjustments on to a millimeter paper), restoring cranial symmetry to perfection (a comparison of the intact side against the side with the defect) without the burden of an exothermic reaction on brain tissue, and minimal production cost
