The aims of this study were to analyze the anatomic variations of supraorbital foramina/notches in Koreans and to compare the results with those of previous studies examining other races. We evaluated the three-dimensional computed tomography (3D-CT) images of human faces using multidetector computed tomography (MDCT).
A total of 395 adults (232 men and 163 women) were enrolled and the 3D-CT images of their faces were reviewed in this study. In this study, the data from the images included the presence, shape, width and distance from the nasion to the supraorbital foramina/notches. ANOVA was used to assess the main effects of gender and side (right or left foramen/notch), and comparisons of the means were done by paired t-test.
The most common shapes in Koreans were a single notch (39.5%) on the right hand side and a single foramen (42.3%) on the left hand side. The incidence of a single foramen in Koreans was high compared to other races. The mean foramen diameter was 2.34 ± 0.78 mm, and the mean distance from the nasion was 27.19 ± 4.03 mm. The mean notch diameter was 3.37 ± 1.71 mm, and the mean distance from the nasion was 23.42 ± 2.45 mm.
This is the first study on the variations of supraorbital foramina/notches in Koreans using 3D-CT images of faces. The anatomic characteristics of the supraorbital foramina/notch will help in performing nerve blocks and maxillofacial surgery.
本研究旨在分析韩国人眶上切迹/切痕的解剖变异,并与以往研究其他种族的结果进行比较。我们使用多层螺旋 CT(MDCT)对人脸的三维 CT(3D-CT)图像进行了评估。
本研究共纳入 395 名成年人(232 名男性和 163 名女性),并对其面部的 3D-CT 图像进行了回顾性分析。在本研究中,图像数据包括存在、形状、宽度以及眶上切迹/切痕与鼻根的距离。采用方差分析评估性别和侧别(右侧或左侧切迹/切痕)的主要影响,并用配对 t 检验比较均值。
在韩国人中,最常见的形状是右侧单个切痕(39.5%)和左侧单个眶上孔(42.3%)。与其他种族相比,韩国人的单个眶上孔发生率较高。眶上孔直径的平均值为 2.34 ± 0.78mm,鼻根至眶上孔的距离平均值为 27.19 ± 4.03mm。切痕直径的平均值为 3.37 ± 1.71mm,鼻根至切痕的距离平均值为 23.42 ± 2.45mm。
这是首次使用面部 3D-CT 图像研究韩国人眶上切迹/切痕的变异。眶上切迹/切痕的解剖特征有助于神经阻滞和颌面外科手术。
