This study aims to evaluate how the extent of altering lip projection in women and chin position in men influences the 22-year-old Caucasian's facial profile attractiveness, in relation to respondents' sex, age and place of residence.
One female and one male orthognathic (SNA angle = 79-85°, Z angle = 75-78°) face profiles, with lips correctly positioned in relation to the E-line were photographed and digitally modified. This processing resulted in 30 photographs varying as for 1. the SNA angle determining orthognathic, prognathic (SNA angle >85°), or retrognathic (SNA angle <79°) profile and 2. lip projection/chin position: normal or protruded/retruded by 1 or 2 mm. The photographs were always shown in the same order to 418 respondents (306 women and 112 men) aged between 15 and 73 years, who provided their place of residence. The 11-point visual analogue scale (VAS) was used for the assessment of the facial profile attractiveness.
All respondents found the prognathic profile with correct lip position in woman and correct chin position in man most attractive. Each major deviation from the norm resulted in a decrease in the scores awarded. Men ranked rethrognathic profiles significantly (p < 0.05) higher than women. The respondents under and over 25 years also differred (p < 0.05) in their evaluation: the older viewers were more critical regarding all female profiles with an exception of the retrognathic profile with 2 mm lips protrusion. The respondents' place of residence did not affect the rating.
1 mm modification of lip projection and chin position significantly alter ranking the face profile attractiveness, thus any aesthetic medicine applied in this area requires extreme caution. Moreover, visualizing the results should be mandatory, especially in women older than 25 years of age, who are the most critical evaluators.
本研究旨在评估改变女性唇部前突程度和男性下巴位置对22岁白种人面部轮廓吸引力的影响，并探讨其与受访者性别、年龄和居住地的关系。
拍摄一名女性和一名男性正颌（SNA角=79-85°，Z角=75-78°）面部轮廓照片，照片中嘴唇相对于E线位置正确，然后进行数字修改。处理后得到30张照片，这些照片在以下两方面有所不同：1. SNA角决定正颌、前突（SNA角>85°）或后缩（SNA角<79°）轮廓；2. 唇部前突/下巴位置：正常或前突/后缩1或2毫米。照片始终以相同顺序展示给418名年龄在15至73岁之间的受访者（306名女性和112名男性），他们提供了自己的居住地。采用11点视觉模拟量表（VAS）评估面部轮廓吸引力。
所有受访者都认为女性唇部位置正确且男性下巴位置正确的前突轮廓最具吸引力。与正常情况的每一次重大偏差都会导致评分下降。男性对后缩轮廓的评分显著高于女性（p<0.05）。25岁以下和25岁以上的受访者在评价上也存在差异（p<0.05）：年龄较大的观察者对所有女性轮廓更为挑剔，但唇部前突2毫米的后缩轮廓除外。受访者的居住地不影响评分。
唇部前突和下巴位置1毫米的改变会显著改变面部轮廓吸引力的排名，因此在该领域应用任何美容医学都需要极其谨慎。此外，应强制进行结果可视化，尤其是对于25岁以上的女性，她们是最挑剔的评估者。
