Objectives To evaluate the average thickness of the parietal bones in their different regions to identify the ideal site(s) for calvarial bone graft harvest. Methods and Materials Thickness of the parietal bones of 25 wet cranial vaults of New Zealand European origin was measured in 135 different locations using an electronic caliper. Analyses to identify the ideal harvest sites were conducted so that the sites fit the features of an ideal harvest site described in the literature as: (1) 6 mm of minimum thickness and (2) 2 cm away from the midline. Results and Conclusion The overall average thickness was 6.69 ± 0.22 mm. The average thickness at different sites within the same bone ranged from 2.85 to 6.93 mm. In keeping with previous studies, the report observed a progressive thickening of the parietal bone in medial and posterior directions. Of the 135 different locations measured, only 20% exceeded an average thickness of 6 mm as well as being 2 cm away from the sagittal midline. These locations were mainly located between 6 to 11 cm posterior to the coronal suture and 2 to 5 cm away from the sagittal suture. Conclusion Harvesting the calvarial bone graft in the area 6 to 11 cm posterior to the coronal suture and 2 cm away from the midline is recommended based on our study using cadaveric cranial vaults of New Zealand Europeans.
目的 评估顶骨不同区域的平均厚度，以确定颅骨骨移植取材的理想部位。方法与材料 使用电子卡尺在25个新西兰欧洲裔湿颅顶的顶骨上135个不同位置测量厚度。进行分析以确定理想的取材部位，使这些部位符合文献中描述的理想取材部位特征：（1）最小厚度6毫米，（2）距中线2厘米。结果与结论 总体平均厚度为6.69±0.22毫米。同一颅骨内不同部位的平均厚度在2.85至6.93毫米之间。与先前研究一致，该报告观察到顶骨在向内侧和后方方向逐渐增厚。在测量的135个不同位置中，只有20%超过平均厚度6毫米且距矢状中线2厘米。这些位置主要位于冠状缝后方6至11厘米且距矢状缝2至5厘米之间。结论 根据我们对新西兰欧洲裔尸体颅顶的研究，建议在冠状缝后方6至11厘米且距中线2厘米的区域取材颅骨骨移植。
