摘　　要：目的研究鼻唇角改变对软组织侧貌审美的影响,并研究不同人群对于鼻唇角审美评价的差异。方法选择一位软硬组织测量值均符合中国女性正常标准的年轻女性作为研究对象,拍摄其自然头位时的侧貌照片,应用Photoshop软件根据不同的鼻尖旋转度和上唇旋转度组合得到33张不同的面型侧貌图。选择33名正畸医生作为专业组和64名学生作为非专业组对随机排序的33张图用Likert量表进行审美评分。结果当上唇位置不变时,鼻尖旋转度不变或变化较小的侧貌较为美观;当鼻尖旋转度不变时,专业组和非专业组都更能接受上唇内收的侧貌;当鼻尖旋转度无论发生顺时针还是逆时针旋转时,专业组和非专业组均认为唇部内收的侧貌更美观。结论无论鼻唇角偏大还是偏小的情况下,上唇内收的侧貌都是比较美观的。提示正畸治疗过程中,需要对上切牙进行适当的内收和直立。Objective To study the influence ofnasolabial angle alteration on facial profile attractiveness and investigate the perception differences in profile attractiveness among laypeople. Methods A young Chinese female with normal hard and soft tissue cephalometric values was chosen as a research object. Profile photograph was taken in a natural head position. Photoshop software was chosen to rotate the nose tip and upper lip, thus changing the degree and direction of nasolabial angle. A total of 33 different profile pictures were achieved. Thirty-three professional orthodontists and 64 non-professionals were chosen to score these 33 pictures. Results When the upper lip position was fixed, the profile was considerably attractive because the angle of nasal tip was not changed or altered. When the nasal tip rotation angle was fixed, profiles with a retroclined upper lip were considered significantly attractive by the layperson and professional groups. Regardless of the direction of the nasal tip rotation, the respondents considered the profile with a retroclined upper lip highly attractive. Conclusion The soft tissue profile with a retroclined upper lip looks considerably attractive in Chinese female populations. Therefore, during an orthodontic treatment, appropriate retraction of the incisor is recommended to improve soft tissue profile attractiveness.
