A naturally aged face is often characterized by a noticeable lack of jawline contour and decreased volume in the lower region. Several options are available to redefine the jawline. To objectively evaluate treatment-related improvements in clinical practice and research, a validated photonumeric scale is needed.
To present scale-development methods for the Merz Jawline Assessment Scale and establish its reliability.
A 5-point photonumeric scale was developed to objectively assess jawline volume loss and contour disruption using male and female subjects of various ages and skin types. Seven board-certified dermatologists and plastic surgeons evaluated 90 subjects live in 2 sessions, 3 weeks apart to establish intra- and interrater reliability.
The weighted kappa for intra- and interrater agreement were ≥ 0.7 in all cases. Intrarater agreement between the 2 rating sessions was nearly perfect (median weighted kappa = 0.908). Substantial interrater agreement between each rater pair was also demonstrated for both rating sessions.
The Merz Jawline Assessment Scale is a validated and reliable photonumeric scale for rating loss of jawline volume and contour. The scale maintains its validity and reliability with reproducible results across a diverse group of males and females of various ages and Fitzpatrick skin types.

自然衰老的面部通常表现为明显的下颌轮廓缺失和下部区域体积减小。有多种方法可用于重新定义下颌轮廓。为了在临床实践和研究中客观评估与治疗相关的改善情况，需要一种经过验证的数字评分量表。
介绍Merz下颌轮廓评估量表的量表开发方法并确定其可靠性。
开发了一种5分数字评分量表，用于客观评估不同年龄和皮肤类型的男性和女性的下颌轮廓体积损失和轮廓破坏情况。七位获得委员会认证的皮肤科医生和整形外科医生分两个阶段对90名受试者进行了现场评估，两个阶段相隔3周，以确定评分者内和评分者间的可靠性。
在所有情况下，评分者内和评分者间一致性的加权kappa值均≥0.7。两次评分之间的评分者内一致性几乎完美（中位数加权kappa = 0.908）。两个评分阶段的每对评分者之间也显示出高度的评分者间一致性。
Merz下颌轮廓评估量表是一种经过验证且可靠的数字评分量表，用于评估下颌轮廓体积和轮廓的损失。该量表在不同年龄和Fitzpatrick皮肤类型的男性和女性群体中保持其有效性和可靠性，结果具有可重复性。《药物皮肤病学杂志》。2023年；22(2):203 - 209。doi:10.36849/JDD.7193。
