Although some data for western norms in orbit shape were reported, the standard norms for Asian orbits were not established yet. The data would be very valuable for the various surgical procedures as well as the production of the appropriate instruments and implants. Therefore, we suggest a Korean orbit mean shape model based on the three-dimensional computer modeling, which includes the analysis of the various parameters with the calculated average value, thereby providing a standard mean shape orbital model that could be used for the Asian patients' orbital surgeries. This paper would be the first literature that provides the standard orbit model for Asians. We developed orbit-specific computer software (AMC-SWU) for the production of an orbit mean shape model. The production steps included semi-automatic segmentation, shape reconstruction, statistical shape model generation, and mean shape and variance model production. The study included records of 48 male and 48 female patients who met the inclusion criteria. Three-dimensional facial bone computed tomography (CT) images of 96 patients were obtained, and these images were used to produce a representative mean shape model. The mean models had vertical dimensions of 36.93 and 35.11 mm, horizontal dimensions of 38.49 and 36.79 mm, and rim dimensions of 45.76 and 42.90 mm for males and females, respectively. We developed a realistic, visualized three-dimensional Korean orbit mean shape model and compared its parameters with calculated values. There is a variance in orbital dimensions between the sexes and the orbital changes with age. We also demonstrated orbital anatomic differences between ethnic groups.
尽管已经报道了一些关于西方人眼眶形状的标准数据，但亚洲人眼眶的标准数据尚未建立。这些数据对于各种手术以及合适的手术器械和植入物的生产都非常有价值。因此，我们基于三维计算机建模提出了一个韩国眼眶平均形状模型，该模型包括对各种参数的分析和计算平均值，从而提供了一个可用于亚洲患者眼眶手术的标准平均形状眼眶模型。本文将首次为亚洲人提供标准眼眶模型。我们开发了一种特定于眼眶的计算机软件（AMC-SWU），用于制作眼眶平均形状模型。制作步骤包括半自动分割、形状重建、统计形状模型生成以及平均形状和方差模型制作。该研究纳入了符合纳入标准的 48 名男性和 48 名女性患者的记录。我们获得了 96 名患者的三维面部骨骼 CT 图像，并使用这些图像生成了一个代表性的平均形状模型。男性和女性的平均模型垂直尺寸分别为 36.93 和 35.11mm，水平尺寸分别为 38.49 和 36.79mm，眶缘尺寸分别为 45.76 和 42.90mm。我们开发了一个逼真的、可视化的三维韩国眼眶平均形状模型，并比较了其参数与计算值。男女之间的眼眶尺寸存在差异，眼眶尺寸也会随年龄变化。我们还展示了不同种族之间的眼眶解剖差异。
