测量面部结构的方法有很多，近年来，关于三维分析的报道和临床研究有所增加。特别是，三维光学扫描系统不仅可以快速、高精度地进行测量，而且没有辐射。我们新开发了一种配备了头固定器的非接触式三维光学扫描系统（SURFLACERVMH-300 F），并研究了面部软组织上特定标志点定位的可靠性、准确性和稳定性。利用该系统和逆向工程软件（Imageware 9）对10名日本成年人的面部结构进行了5次测量和分析，结果如下. 2.利用固定器进行高精度测量，无需矫正位置，测量精度高。但矫正后的准确率有所提高.测量基准点的平均误差为2.68±0.89mm，其中前额区的基准点重复性好，口角和下颌角的基准点重复性差。
There are many methods of measuring facial configurations, and in recent years, reports and clinical studies on three-dimensional analysis have increased. Especially, the 3D optical scanning system offers not only rapid high-precision measurement but also no radiation exposure.We have newly developed a non-contact 3D optical scanning system (SURFLACER VMH-300F) which is equipped with cephalostats, and investigated the reliability, accuracy and stability of locating specific landmarks on facial soft tissue. We measured and analyzed the facial configurations of 10 adult Japanese, 5 times per subject, using this system and reverse engineering software (Imageware 9).The results were as follows.1. The operation of rectifying a position could be reduce the error to 0.63±0.15mm.2.High-precision Measurement could be performed by using cephalostats, without rectifying a position. However, rectifying increased the accuracy.3. The meanerrorof the measurement datum point was 2.68±0.89mm, the datum point of the foreheadarea had high reproducibility, and the datum point of the angle of mouth and angle of mandible had low reproducibility.
