Validated Composite Assessment Scales for the Global Face

Abstract

The aesthetic grading scales and global scales on estimated age and aesthetic treatment effort are reliable and valid instruments. The results suggest that a more-comprehensive evaluation of the human face and its age-related changes can help to identify important areas of facial aging and to define optimal aesthetic treatment strategies.

Validated Assessment Scales for the Upper Face

“…The chosen population was within the framework of the Scale Summit I [23][24][25][27][28][29] and represents a spectrum that is neither too diverse nor too specific, as in a clinical study. Subjects were not to have facial hair, scarring, any previous treatment with toxins or fillers, any surgical procedures in the area of interest (treatment naïve), or HIV-related lipoatrophy.…”

“…The number of subjects for the Scale Summit II (50) was greater than for the Scale Summit I (35), [23][24][25][27][28][29] which is a common basis for such validations. The scale-creation team preselected approximately 100 photographs for validation of the upper face scales.…”

“…The search references refer to the validated grading scales for , forehead lines, 23 crow's feet 24 and brow positioning. 27 Twenty facial scales were validated at the Scale Summit II, including already-existing validated scales such as those for forehead lines and crow's feet 23,24 and newly developed scales for glabellar lines and sex-specific brow positioning, allowing assessment of the entire upper face aesthetic unit and the global face.…”

Validated Assessment Scales for the Mid Face

“…15 Two of the three new mid face scales assess the agerelated volume changes of the cheek. They have been developed to provide an innovative means of measuring these discrete human mid face areas in an objective and reproducible way.…”

Validated Assessment Scale for Neck Volume

“…37 Thus, we developed and validated a new, image-simulated grading scale that objectively assesses the aging neck, with the focus on neck volume.…”
