The relationship between cephalometric measurements and facial attractiveness may differ by gender. This study aimed to compare the maximum attractiveness values (MAVs) for cephalometric measures significantly associated with facial profile attractiveness between male and female patients for the first time.
Sixteen laypersons evaluated the facial attractiveness of 180 Chinese adult patients (90 males and 90 females) who had not undergone orthodontic treatment, using photographs. The quadratic correlation between 27 cephalometric measures and facial attractiveness was calculated, and the MAVs for significant cephalometric measures were identified.
Twelve cephalometric measures were significantly related to facial attractiveness in both male and female patients, including: angle of convexity [MAV (male)=1.4 deg., MAV (female)=7.1 deg.], L1/FH (63.8 deg., 58.6 deg.), SNB (79.2 deg., 76.4 deg.), ANB angle (1.3 deg., 3.6 deg.), L1/NB (24.6 deg., 26.9 deg.), profile angle (169.6 deg., 167.3 deg.), facial angle (89.5 deg., 88.1 deg.), Z-angle (75.3 deg., 74.3 deg.), H-angle (17.6 deg., 18 deg.), Wits appraisal (-0.5 mm, 1.4 mm), upper lip to E-line (-0.7 mm, 0.3 mm), and L1-NB (5.1 mm, 5.8 mm).
Significant differences were found in the MAVs for many cephalometric measures between male and female patients, suggesting that current normal values for cephalometric measures may not accurately reflect facial attractiveness. The MAVs for the ANB angle, angle of convexity, and Wits appraisal indicated that nonprofessionals tend to perceive women with a less pronounced chin/jaw as more attractive. Future studies on facial aesthetics should ideally categorize samples by gender.
头影测量值与面部吸引力之间的关系可能因性别而异。本研究旨在首次比较男性和女性患者中与面部轮廓吸引力显著相关的头影测量指标的最大吸引力值（MAV）。
16名外行人通过照片对180名未接受过正畸治疗的中国成年患者（90名男性和90名女性）的面部吸引力进行评估。计算27项头影测量指标与面部吸引力之间的二次相关性，并确定显著头影测量指标的MAV。
12项头影测量指标在男性和女性患者中均与面部吸引力显著相关，包括：凸度角[MAV（男性）=1.4度，MAV（女性）=7.1度]、L1/FH（63.8度，58.6度）、SNB（79.2度，76.4度）、ANB角（1.3度，3.6度）、L1/NB（24.6度，26.9度）、侧面角（169.6度，167.3度）、面部角（89.5度，88.1度）、Z角（75.3度，74.3度）H角（17.6度，18度）、Wits值（-0.5毫米，1.4毫米）、上唇至E线（-0.7毫米，0.3毫米）以及L1-NB（5.1毫米，5.8毫米）。
男性和女性患者在许多头影测量指标的MAV上存在显著差异，这表明当前头影测量指标的正常值可能无法准确反映面部吸引力。ANB角、凸度角和Wits值的MAV表明，非专业人士倾向于认为下巴/下颌不太突出的女性更具吸引力。未来关于面部美学的研究最好按性别对样本进行分类。
