目的：评价下唇隆起对矢状面不同程度下巴隆起的影响，探讨下唇隆起是否影响手术意愿。评估正畸医生和外行人的偏好差异，以及观察者的年龄、性别和种族对吸引力和手术欲望的影响。材料和方法：创建一个理想的侧面图像的轮廓。通过对图像进行处理，生成了6张图像，显示了从-12 mm到+12 mm的4毫米增量中不同程度的回孕和早孕，以及6张从-12 mm到+12 mm的4毫米增量中显示下巴和下唇突出的图像。100名外行人和30名正畸医生将这些照片从最吸引人的到最不吸引人的排序。为了评估内测者的可靠性，使用了其中一幅图像的副本。结果：下颌矢状位的大小、方向和下唇的突出程度对图像排序有显著影响。颏前突不如后突有吸引力，因此需要更多的手术治疗。外行人和正畸医生的总体意见方向相同。结论：在下颌前突患者中观察到的下巴突出被认为不如在下颌前突患者中观察到的下巴和下唇联合突出。在轮廓较突出的下巴，更突出的下唇位置是首选。当下巴后缩时，正常的下唇位置优于后缩的下唇位置。
Objectives: To evaluate the influence of the lower lip prominence for varying degrees of chin prominence in the sagittal plane and to establish whether lower lip prominence affects the perceived desire for surgery. To assess differences in preference between orthodontists and laypeople as well as the effect of age, gender, and ethnicity of observers on perceptions of attractiveness and desire for surgery.Materials and Methods: A silhouette of an idealized profile image was created. The image was manipulated to create six images demonstrating different degrees of retrogenia and progenia altered in 4-mm increments from -12 mm to +12 mm and six images demonstrating chin and lower lip prominence in 4-mm increments from -12 mm to +12 mm. One hundred laypeople and 30 orthodontists ranked the images from the most to the least attractive. A duplicate of one of the images was used in order to assess intraexaminer reliability.Results: The amount and direction of sagittal chin position and the prominence of the lower lip were found to have a significant effect on image rank. Chin protrusion was less attractive than retrusion and surgery was desired more often for these images. The overall direction of opinion was the same for laypeople and orthodontists.Conclusions: The chin prominence observed in a progenic patient is deemed less attractive than the combined chin and lower lip prominence observed in a patient with mandibular prognathism. In profiles with a more prominent chin a more protrusive lower lip position was preferred. When the chin was retrusive, a normal lower lip position was preferred to a retrusive lip.
