Analysis of the evaluation for the features of patients with a jaw Deformity-Application of eye tracking method and the qualitative Evaluation-

本研究的目的是探讨客观和主观评价的面部不对称性和注视点分析的评价者使用眼动追踪方法判断对称性之间的关系。对30例颌骨畸形患者的正位片进行了评价，评价对象为10名口腔颌面外科医生和10名口腔颌面外科医生。提示颏区偏位程度和唇倾斜度对面部不对称的主观评价有较大影响。注视点分析显示，最初的注视点最常见的是鼻子，最长的注视时间观察到的精神区域，其次是鼻子，然后是嘴唇。

The aim of this study was to investigate the relationship among objective and subjective evaluations of facial asymmetry and gaze point analysis of the evaluators using an eye-tracking method when judging symmetry. Evaluations on the frontal view photographs of 30 patients with jaw deformity were conducted by 10 oral and maxillofacial surgeons and 10 orthodontists. It is suggested that the degree of deviation of the mental region and lip inclination have a large effect on the subjective evaluation of facial asymmetry. Gaze point analysis revealed that the initial gaze point was most often the nose and longest gaze times were observed for the mental region followed by the nose then the lip.
