Abstract

BACKGROUND

Photographic scales have become an increasingly used tool in objectively assessing outcomes in aesthetic surgery. However, no online photographic scale for assessing breast ptosis has been developed yet that is readily available.

OBJECTIVES

This study was designed to validate the online Rainbow Scale for the assessment of breast ptosis for the anterior-posterior (AP), lateral, and oblique views.

METHODS

For the five grades of the Rainbow Scale format, standardized reference photographs were selected. Six plastic surgeons rated 15 photographs for each view three times. Intra- and inter-observer agreements were calculated by using the weighted kappa coefficient and differences in intra- and inter-observer agreements between the three views were assessed for statistical significance using the Kruskal-Wallis test.

RESULTS

The mean intra-observer agreements were 0.91 (range, 0.82-0.98) for the AP view, 0.88 (range, 0.77-1.00) for the oblique view, and 0.86 (range, 0.74-0.97) for the lateral view and did not vary significantly between all three views. The mean inter-observer agreements were 0.88 (range, 0.77-0.95) for the AP view, 0.84 (range, 0.72-0.94) for the oblique view, and 0.82 (range, 0.58-0.95) for the lateral view. The mean inter-observer agreements of the AP view varied significantly from the oblique view (P = .012) and the lateral view (P = .001).

CONCLUSIONS

The Rainbow Scale for breast ptosis has been validated for the AP view, the lateral view, and the oblique view and is reproducible and reliable for the assessment of breast ptosis in three different views in an online setup.

摘要

背景

照片量表已日益成为客观评估美容手术效果的工具。然而，目前尚无现成的用于评估乳房下垂的在线照片量表。

目的

本研究旨在验证用于评估乳房下垂的前后位（AP）、侧位和斜位视图的在线彩虹量表。

方法

针对彩虹量表格式的五个等级，选取了标准化参考照片。六位整形外科医生对每个视图的15张照片进行了三次评分。采用加权kappa系数计算观察者内和观察者间的一致性，并使用Kruskal-Wallis检验评估三个视图之间观察者内和观察者间一致性的差异是否具有统计学意义。

结果

AP视图的观察者内一致性均值为0.91（范围0.82 - 0.98），斜位视图为0.88（范围0.77 - 1.00），侧位视图为0.86（范围0.74 - 0.97），且在所有三个视图之间差异无统计学意义。AP视图的观察者间一致性均值为0.88（范围0.77 - 0.95），斜位视图为0.84（范围0.72 - 0.94），侧位视图为0.82（范围0.58 - 0.95）。AP视图的观察者间一致性均值与斜位视图（P = 0.012）和侧位视图（P = 0.001）相比差异有统计学意义。
