To test the hypothesis that the faces of patients with a severe Class III are contemplated differently from and assessed more negatively than skeletal Class I patients in direct face-to-face interaction.
The eye movements of 24 randomly recruited evaluators were analyzed with a noninvasive, infrared high-speed camera while looking at 18 standardized frontal photographs of adult orthognathic Class III patients and 18 photographs of adults with skeletal Class I relationships as controls. Additionally, all images were assessed for appearance, symmetry, and facial expression.
The Class III patients were rated significantly more negatively in terms of appearance, symmetry, and facial expression than the Class I individuals. The eye movement data revealed that orthognathic patients were appraised differently from the Class I individuals, with fewer fixations in the face center, especially around the mouth.
Skeletal Class III patients were characterized as less attractive than Class I individuals. Faces of Class III patients were visually perceived with different eye movements. These differences in visual perception are described for the first time in the present study. Although they were small, they are an indication of an objectively different perception of faces that are rated subjectively as less attractive and more asymmetric and exhibiting a more negative expression.
检验以下假设：在直接面对面互动中，严重III类错颌患者的面部与骨骼I类患者的面部相比，会被以不同方式看待且评估更为负面。
使用非侵入性红外高速摄像机分析24名随机招募的评估者在观看18张成年正颌III类患者的标准化正面照片和18张作为对照的骨骼I类关系成年人照片时的眼动情况。此外，对所有图像的外观、对称性和面部表情进行评估。
III类患者在外观、对称性和面部表情方面的评分显著低于I类个体。眼动数据显示，正颌患者与I类个体的评估方式不同，在面部中心尤其是嘴部周围的注视较少。
骨骼III类患者的特征是不如I类个体有吸引力。III类患者的面部在视觉上通过不同的眼动被感知。本研究首次描述了这些视觉感知上的差异。尽管差异很小，但它们表明了对面部存在客观上不同的感知，这些面部在主观上被评为吸引力较低、更不对称且表情更负面。
