The purpose of this study is to assess the applicability of facial soft tissue measurements using 3-dimensional reconstructed MDCT and to compare the results with previously reported Japanese data.
This study included 50 Japanese cadavers who underwent postmortem whole body 16-detector CT within 0-3 days after death. Using 3-D workstation, 10 anthropological measuring points were located and the soft tissue thicknesses were measured. The differences between the acquired thickness and the previously reported Japanese average thickness were statistically analyzed.
All measuring points were readily determined on the 3-dimensional reconstructed images. Previous Japanese cadaveric data was thinner than our data in almost all sites except for 1 measuring point (mid-philtrum). Previous living Japanese data was thicker than ours except for 1 measuring point (end of nasal).
Facial soft tissue thickness was easily assessed using 3-D reconstructed MDCT images. At many measuring points, our results were thicker than previously reported cadaveric data and were thinner than the data from live persons.
本研究旨在评估使用三维重建MDCT进行面部软组织测量的适用性，并将结果与先前报道的日本数据进行比较。
本研究纳入了50具日本尸体，这些尸体在死后0至3天内接受了尸体全身16排CT检查。使用三维工作站，确定了10个人类学测量点并测量了软组织厚度。对获得的厚度与先前报道的日本平均厚度之间的差异进行了统计分析。
在三维重建图像上所有测量点都很容易确定。除了一个测量点（人中中部）外，先前的日本尸体数据在几乎所有部位都比我们的数据薄。除了一个测量点（鼻端）外，先前的日本活体数据比我们的数据厚。
使用三维重建MDCT图像可以轻松评估面部软组织厚度。在许多测量点，我们的结果比先前报道的尸体数据厚，比活体数据薄。
