Abstract：
BACKGROUND: Orthognathic surgery is a multidisciplinary surgery in which the aesthetic results have become increasingly important, and consequently, also the predictability of the surgical outcomes. In this paper, we analyzed the volumetric distribution of the lower two-thirds of the face, in patients operated by orthognathic surgery and selected for their attractiveness. Our goal was to analyze the aesthetic volumetric distribution for gender and to propose our operating philosophy, that a normative distribution of facial volumes could be used like a new 3D aesthetic guide in orthognathic planning.
METHODS: A group of 46 orthognathic patients (26 females, 20 males) with the best postoperative aesthetic score was selected by a jury of plastic surgeons, orthodontists, and journalists. The mean soft tissue volumes of the malar, maxillary, mandibular, and chin regions were analyzed.
RESULTS: Overall, we measured a mean female facial volume distribution of 38.7%, 29%, 27.6%, and 4.7%, respectively, in the malar, maxillary, mandibular, and chin regions, while in males, it was 37%, 26%, 30%, and 6%, respectively.
CONCLUSIONS: In this paper, the expansion of facial volumes in orthognathic surgery is proposed as a key point for facial harmonization. Beauty could be scientifically interpreted as a balanced distribution of facial volumes, and the virtual study of this distribution can become an important part of the preoperative analysis, such as a \"volumetric\" 3D cephalometry, where the surgeon could use average values of aesthetic volumetric distribution as preoperative surgical references.

摘要：
背景：正颌手术是一种多学科手术，其中美学结果变得越来越重要，因此，手术结果的可预测性。在本文中,我们分析了面部下三分之二的体积分布，在正颌手术的患者中，并根据他们的吸引力进行选择。我们的目标是分析性别的美学体积分布，并提出我们的经营理念，面部体积的规范分布可以像正颌规划中的新3D美学指南一样使用。
方法：一组46名正颌患者（26名女性，由整形外科医生组成的陪审团选出了具有最佳术后美学评分的20名男性），正畸医生,和记者。颌骨的平均软组织体积，上颌,下颌,和下巴区域进行了分析。
结果：总体而言，我们测量的女性面部平均体积分布为38.7%，29%,27.6%,和4.7%，分别,在马拉尔，上颌,下颌,和下巴区域，而在男性中，是37%,26%,30%,6%,分别。
结论：在本文中，正颌手术中面部体积的扩大被认为是面部协调的关键点。美丽可以被科学地解释为面部体积的平衡分布，这种分布的虚拟研究可以成为术前分析的重要组成部分，如“体积”三维头影测量，外科医生可以使用美学体积分布的平均值作为术前手术参考。
