This study used anthropometric data in the form of Farkas' proportion indices in order to quantify facial attractiveness, and to relate measured change through surgery, to clinical judgement. Standardized photographs of 15 orthognathic patients were used in album form and rated by 10 experienced clinicians: album 1 for facial attractiveness (before surgery) and album 2 for improvement in facial attractiveness (before and after surgery). Twenty-five proportion indices were selected and linear measurements recorded from the pre- and post-surgical photographs. The corresponding change in indices and in clinicians' scores were compared. The clinicians' assessment of the degree of improvement in facial appearance achieved through surgery, related closely to the scores produced by the change in proportion indices (r = 0.698, P = 0.004). Clinical assessment demonstrated a clear inverse relationship between initial attractiveness rating and the degree of improvement achieved through orthognathic surgery (r = -0.781, P = 0.001). The results showed good repeatability in terms of clinical assessment, photography and digitization. The method would appear to have potential for further development, possibly into a 'facial attractiveness index' for the objectives of quantification of improvement achieved through treatment.
本研究使用法卡斯比例指数形式的人体测量数据，以量化面部吸引力，并将手术测量的变化与临床判断相关联。15名正颌患者的标准化照片以相册形式呈现，并由10名经验丰富的临床医生进行评分：相册1用于评估面部吸引力（手术前），相册2用于评估面部吸引力的改善情况（手术前后）。选择了25个比例指数，并从手术前后的照片中记录线性测量值。比较了指数变化与临床医生评分的相应变化。临床医生对通过手术实现的面部外观改善程度的评估，与比例指数变化产生的评分密切相关（r = 0.698，P = 0.004）。临床评估表明，初始吸引力评分与通过正颌手术实现的改善程度之间存在明显的负相关（r = -0.781，P = 0.001）。结果表明，在临床评估、摄影和数字化方面具有良好的可重复性。该方法似乎有进一步发展的潜力，可能会发展成为一个“面部吸引力指数”，用于量化通过治疗实现的改善情况。
