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

BackgroundThere is a scarcity of scales that assess platysmal bands, wrinkles in the decollete, and horizontal neck lines in the digital and live setting.ObjectivesThe objective of this investigation was to create and validate 5-point photonumeric scales that assess horizontal neck lines, platysmal bands, and wrinkles in the decollete.MethodsA medical team created 3 different novel 5-point photonumeric scales for the assessment of horizontal neck lines, platysmal bands, and decollete wrinkling. Eleven international raters were involved in the digital validation, and 4 raters performed a live validation.ResultsThe 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 decollete, a static scale and a dynamic scale were created and validated. The Croma Static Decollete 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 Decollete Wrinkles Assessment Scale showed almost perfect agreement in both validation settings for both interrater and intrarater measures.ConclusionsThe Croma Horizontal Neck Lines Assessment Scale and the Croma Static and Dynamic Decollete Wrinkles Assessment Scales have sufficient interrater and intrarater agreement for justifiable use in clinical and research settings.
