Novel, Validated 5-Point Photonumeric Scales for Assessment of the Neck and Décolleté.

BACKGROUND

There is a scarcity of scales that assess platysmal bands, wrinkles in the décolleté, and horizontal neck lines in the digital and live setting.

OBJECTIVES

The objective of this investigation was to create and validate 5-point photonumeric scales that assess horizontal neck lines, platysmal bands, and wrinkles in the décolleté.

METHODS

A medical team created 3 different novel 5-point photonumeric scales for the assessment of horizontal neck lines, platysmal bands, and décolleté wrinkling. Eleven international raters were involved in the digital validation, and 4 raters performed a live validation.

RESULTS

The Croma (Leobendorf, Austria) Horizontal Neck Lines Assessment Scale showed substantial interrater agreement and almost perfect intrarater agreement in the digital and live validations, respectively. The Croma Platysmal Bands Assessment Scale showed substantial intrarater agreement in both digital and live validations. For the décolleté, a static scale and a dynamic scale were created and validated. The Croma Static Décolleté Wrinkles Assessment Scale showed substantial and almost perfect interrater agreement in the digital and live validations, respectively, and the intrarater agreement in both was almost perfect. The Croma Dynamic Décolleté Wrinkles Assessment Scale showed almost perfect agreement in both validation settings for both interrater and intrarater measures.

CONCLUSIONS

The Croma Horizontal Neck Lines Assessment Scale and the Croma Static and Dynamic Décolleté Wrinkles Assessment Scales have sufficient interrater and intrarater agreement for justifiable use in clinical and research settings.
