Manufacturing a spectacle frame for a facially deformed individual is challenging because of facial asymmetry. One of the solutions is the customization of spectacle frames. Customization of spectacle frames for facially deformed individuals requires a better understanding of the facial anthropometry of deformed faces. This study aimed to analyze the facial anthropometry of deformed faces to understand the range of variability. The results of this study will be used to find customization methods in the future.
We measured and analyzed the 12 facial parameters of individuals with facial deformities using the ImageJ software.
The data collected were normally distributed. Paired sample test revealed a statistically significant difference between innercanthus distances (right innercanthus distance [RICD] and left innercanthus distance [LICD]). Correlation analysis showed a positive difference between horizontal and vertical pupillary distance-innercanthus distance (PD-ICD) (0.68, 0.75, and 0.81) and pupillary distance-helix distance (PD-HD) (0.57, 0.68, and 0.59) relations. PD-ICD correlations are stronger compared to the PD-HD relation.
Altering the frame center distance and the temple heights are the most important for asymmetric faces. Large population-based data are required to make concrete decisions to design a spectacle frame for asymmetric faces.
由于面部不对称，为面部畸形个体制造眼镜架具有挑战性。解决方案之一是定制眼镜架。为面部畸形个体定制眼镜架需要更好地了解畸形面部的面部人类学。本研究旨在分析畸形面部的面部人类学，以了解可变性范围。本研究的结果将用于未来寻找定制方法。
我们使用 ImageJ 软件测量和分析了 12 名面部畸形个体的 12 个面部参数。
收集的数据呈正态分布。配对样本检验显示内眦距离（右眼内眦距离[RICD]和左眼内眦距离[LICD]）之间存在统计学显著差异。相关分析显示水平和垂直瞳孔距离-内眦距离（PD-ICD）（0.68、0.75 和 0.81）和瞳孔距离-耳轮距离（PD-HD）（0.57、0.68 和 0.59）之间存在正差异关系。PD-ICD 相关性比 PD-HD 关系更强。
对于不对称的面部，改变镜架中心距离和镜腿高度是最重要的。需要基于大量人群的数据来做出具体决策，为不对称面部设计眼镜架。
