The cranium serves as a primary bone graft donor site in reconstructive craniofacial surgery. However, the mechanical properties of cranial bone predispose to fragmentation when excessive bending forces are applied, or to a return to the original shape when bending forces are insufficient. The precise and sustained contouring of cranial bone therefore remains a practical clinical problem. This paper describes a simple surgical technique which relies upon the application of a miniplate to the cortical surface of the cranial bone segment prior to bending. The miniplate serves to reinforce the segment, allowing accurate shaping of cranial bone and maintenance of the newly acquired contour.
颅骨是颅面重建手术中主要的骨移植供区。然而，颅骨的力学特性使其在受到过大弯曲力时容易破碎，而在弯曲力不足时又容易恢复原状。因此，颅骨的精确且持久的塑形仍然是一个实际的临床问题。本文描述了一种简单的手术技术，该技术依靠在弯曲之前将微型钢板应用于颅骨段的皮质表面。微型钢板用于加强该骨段，从而实现颅骨的精确塑形并维持新获得的形状。
