On the basis of Schwarz's [21] facial typology, soft tissue facial profile was evaluated in relation to 3 head positions: natural head position, head position according to the Frankfurter Horizontal, and head position according to a subjective personal appraisal of an aesthetically pleasing profile, i.e. aesthetic head position. Forty children (20 girls and 20 boys) and 40 adults (20 women and 20 men) with varying occlusal relationships constituted the study group. Facial photos oriented according to the above 3 head positions were evaluated. The results revealed that head posture had a decisive impact on the outcome of the facial profile evaluation. Significant differences existed between natural head position on the one hand and Frankfurter Horizontal and aesthetic head position on the other. Due to the relatively large methodological error in the registration of natural head position, and the resulting effect of this error on profile evaluation, natural head position can lead to misleading results. The advantage of Frankfurter Horizontal as opposed to aesthetic head position is the result of a subjective appraisal. Thus, when using Schwarz's method in evaluating facial profile, Frankfurter Horizontal still appears to be quite appropriate.
基于施瓦茨[21]的面部类型学，在3种头部位置下对面部软组织轮廓进行评估：自然头位、根据法兰克福平面确定的头部位置以及根据对美观轮廓的主观个人评价确定的头部位置，即美学头位。40名儿童（20名女孩和20名男孩）和40名成年人（20名女性和20名男性），他们具有不同的咬合关系，构成了研究组。对根据上述3种头部位置定向的面部照片进行评估。结果显示，头部姿势对面部轮廓评估结果具有决定性影响。一方面自然头位与另一方面法兰克福平面和美学头位之间存在显著差异。由于自然头位记录中存在相对较大的方法误差，以及该误差对轮廓评估的影响，自然头位可能导致误导性结果。与美学头位相比，法兰克福平面的优势是主观评价的结果。因此，在使用施瓦茨方法评估面部轮廓时，法兰克福平面似乎仍然相当合适。
