Following the popularity of facial cosmetic procedures to reverse the signs of aging, cosmetic procedures that rejuvenate the hand are being sought. Irregular surface pigmentation, prominence of superficial veins and tendons, thinning of the dermis, and loss of subcutaneous fat typically characterize aging of the hand.
To develop the Hand Grading Scale for objective quantification of the severity of hand aging and to establish the reliability of this photonumeric scale for clinical research and practice.
The Hand Grading Scale is a 5-point photonumeric rating scale that was developed to objectively quantify the severity of aging of the hand. Nine experts rated photographs of 35 subjects, twice, with regard to the aspect "hand aging" in comparison with morphed images. Inter- and intrarater variability was assessed by computing intraclass correlation coefficients.
The agreement between the experts was considerably high. Bubble plots (bivariate scatter plots) demonstrated linearity in judgment by the experts.
The 5-point photonumeric scale generated spans the severity of hand aging for which patients most commonly seek correction. The scale is well stratified for consistent rating.
随着面部美容手术用于逆转衰老迹象的普及，人们开始寻求手部年轻化的美容手术。手部老化的典型特征包括表面色素沉着不规则、浅表静脉和肌腱突出、真皮变薄以及皮下脂肪流失。
制定手部分级量表，以客观量化手部老化的严重程度，并确定该数字量表在临床研究和实践中的可靠性。
手部分级量表是一种5分数字评分量表，旨在客观量化手部老化的严重程度。九位专家对35名受试者的照片进行了两次评分，与变形图像相比，评分涉及“手部老化”方面。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。
专家之间的一致性相当高。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最常寻求矫正的手部老化严重程度范围。该量表分层良好，便于进行一致的评分。
