To determine Korean facial profile preferences based on lip position as assessed by Hispanic-Americans of varying western adaptation levels and to determine whether the age and sex of the rater had any influence.
For this study, 132 Hispanic-Americans and 68 Caucasians of varying age, sex and western adaptation levels volunteered to rate their preference of Korean male and female facial silhouettes having lips ranging from retruding to protruding. The Hispanic-Americans were also asked to complete a Bidimensional Acculturation Scale questionnaire to determine their western adaptation status: low-acculturated Hispanics (LAH; lesser western-adapted Hispanic participants) or high-acculturated Hispanics (HAH; higher western-adapted Hispanic participants).
The LAHs preferred significantly more retruded lip positions (p < 0.05) while HAHs showed some similarities with Caucasian participants in the results for the Korean male profile, even though HAHs preferred more retruded lip positions for the Korean female profile than Caucasians did (p < 0.05). The age and sex of raters did not influence the preference of facial profiles (p > 0.05).
The results of this study suggest that Hispanic-Americans prefer a flatter Korean lip profile. It would be prudent for orthodontists to offer patients the option of altering lip profile through orthodontic and/or orthognathic surgery treatments.
根据不同西方适应水平的西班牙裔美国人对嘴唇位置的评估来确定韩国人面部轮廓偏好，并确定评分者的年龄和性别是否有任何影响。
在本研究中，132名不同年龄、性别和西方适应水平的西班牙裔美国人和68名白种人自愿对嘴唇从后缩到前突的韩国男性和女性面部轮廓进行偏好评分。西班牙裔美国人还被要求完成一份二维文化适应量表问卷，以确定他们的西方适应状态：低文化适应的西班牙裔（LAH；西方适应程度较低的西班牙裔参与者）或高文化适应的西班牙裔（HAH；西方适应程度较高的西班牙裔参与者）。
低文化适应的西班牙裔明显更喜欢后缩的嘴唇位置（p < 0.05），而高文化适应的西班牙裔在韩国男性面部轮廓结果上与白种人参与者有一些相似之处，尽管高文化适应的西班牙裔在韩国女性面部轮廓上比白种人更喜欢后缩的嘴唇位置（p < 0.05）。评分者的年龄和性别不影响对面部轮廓的偏好（p > 0.05）。
本研究结果表明，西班牙裔美国人更喜欢较扁平的韩国嘴唇轮廓。正畸医生谨慎地为患者提供通过正畸和/或正颌手术治疗改变嘴唇轮廓的选择是明智的。
