Melomental folds, or marionette lines, are one of the consequences of facial aging. The curvilinear wrinkles formed because of facial movements and the aging process extend downward from the oral commissures.
To develop the Marionette Lines Grading Scale for objective quantification of the severity of melomental folds and to establish the reliability of this photonumeric scale for clinical research and practice.
A 5-point photonumeric rating scale was developed to objectively quantify the severity of melomental folds. Nine experts rated photographs of 35 subjects, twice, with regard to marionette lines in comparison with morphed images. Inter- and intrarater variability was assessed by computing intraclass correlation coefficients.
The agreement between the experts was high. Bubble plots (bivariate scatter plots) demonstrated linearity in judgment by the experts.
The 5-point photonumeric scale generated spans the severity of marionette lines for which patients commonly seek correction. The scale is well stratified for consistent rating.
嘴角纹，即木偶纹，是面部衰老的后果之一。因面部运动和衰老过程形成的曲线状皱纹从口角向下延伸。
制定木偶纹分级量表，以客观量化嘴角纹的严重程度，并确立该数字量表在临床研究和实践中的可靠性。
制定了一个5分数字评分量表，以客观量化嘴角纹的严重程度。九位专家对35名受试者的照片就木偶纹与变形图像进行了两次评分。通过计算组内相关系数评估评分者间和评分者内的变异性。
专家之间的一致性很高。气泡图（双变量散点图）显示专家的判断具有线性关系。
生成的5分数字量表涵盖了患者通常寻求矫正的木偶纹严重程度范围。该量表分层良好，可进行一致的评分。
