Lower Eyelid Dark Circles (Tear Trough and Lid-Cheek Junction): A Stepwise Assessment Framework.

BACKGROUND: Despite increasing popularity, the use of hyaluronic acid (HA) fillers for the correction of dark under-eye shadows remains challenging. Specific guidance on patient assessment is limited. OBJECTIVES: The aim of this study was to develop a stepwise assessment framework for lower eyelid dark shadows to help practitioners classify patients based on their underlying problems and facilitate a more strategic approach to treatment. METHODS: Literature review and peer collaboration informed the current availability of educational material for use by experienced injectors when assessing patients presenting with dark circles. A practitioner survey provided insight into current practices. A focus group convened to review the survey results and discuss best practice approaches to patient assessment. RESULTS: Surveyed practitioners (n = 39) reported patient concern about under-eye hollows (91%), dark eye circles (80%), and looking tired (60%). All (100%) agreed that midcheek volume was critical when treating tear-trough depression, and only 26% reported use of a tear-trough classification system. The focus group developed a framework for assessing tear-trough depression and the lid-cheek junction in patients presenting with dark circles. Key factors within this framework included the importance of appropriate lighting when conducting a visual inspection, regional inspection of the cheek and tear trough, palpation of the orbital rim and soft tissues, determination of the orbital vector, and assessment of lower eyelid pigmentation and skin quality. CONCLUSIONS: Careful step-by-step assessment can reduce the challenges of treating dark circles by identifying patients in whom dark eye circles may be improved without the need to directly inject filler into the tear trough.

A New Simplified Visual Assessment Tool Describing Facial Morphotypes Observed and Desired in Asian Populations.

OBJECTIVE: A group of established aesthetic physicians sought to develop treatment guidelines for assessing Asian face morphologies that reflect accurate and current beauty standards across Asia. DESIGN: Physicians completed surveys, debated, and voted on their clinical strategies and developed an alternative simplified visual tool of assessment (SVAT) that discerns between country variations in genetic and ideal morphotypes. SETTING: Electronic and paper surveys were followed by consensus debates and voting. PARTICIPANTS: Established aesthetic physicians practicing regularly on Asian patients. MEAUSUREMENTS: A clinically applicable SVAT was developed, which considered facial index, mid-face projection, upper and lower face shape, submalar contour, nose length and dorsal height, eye shape and brow shape, proportion of lips-to-lower face and ratio of upper-to-lower lip, and chin shape. RESULTS: For facial shape change, physicians always assessed the horizontal thirds, facial symmetry, and lip-chin complex profile, and also analyzed overall face shapes and Ogee curves. Criteria for creating oval-shaped faces was also defined and included treating indications, such as loss of angularity and bilateral masseter muscle hypertrophy, narrow jawlines, and longer and wider foreheads. Critical differences and similarities in country-specific aesthetic preferences, treatment requests, and considerations or strategies were uncovered, including the inadequacy of assessing overall peripheral facial shapes. CONCLUSION: This consensus establishes the assessment and treatment criteria for achieving ideal shapes for Asian patients. Specific descriptors are affected by variations; therefore, we present the visual criteria for Asian facial morphotypes. We hope that physicians new to treating Asian patients can use this clinical information to improve their practice.

Validated Assessment Scales for the Female Asian Calf.

BACKGROUND: Clinical photonumeric scales have been developed and validated to objectively measure the effectiveness of aesthetic treatments in specific anatomical areas; however, these are based on the typical features of Caucasian patients. No clinical scale for Asian calf appearance currently exists. OBJECTIVE: To develop and validate a calf assessment scale for use in the female Asian patient population. METHODS AND MATERIALS: During 2 validation sessions, 13 raters assessed calf images of female Asian subjects (N = 35) viewed from behind with feet flat on the floor (at rest) and on tiptoes (dynamic). Images were rated from 0 (very slim, linear profile) to 4 (very severe convex profile). RESULTS: Inter-rater and intra-rater reliability were "substantial" (≥0.6, intraclass correlation coefficient [ICC] and weighted kappa) for the calf-at rest, calf-dynamic, and calf summary score. Reliability was "substantial" for calf-at rest and calf-dynamic (≥0.6, ICC and weighted kappa) and "almost perfect" (0.85) for the calf summary score. BMI and calf circumference were highly correlated with scale ratings, and calf circumference was a significant predictor. CONCLUSION: This new photonumeric assessment scale has value for assessing the female Asian calf, providing a standardized measure of calf appearance in clinical practice and clinical research settings.

A Validated Assessment Scale for Asian Chin Projection.

BACKGROUND: As the number of different aesthetic treatments increase, numerous photonumeric assessment scales have been developed and validated to measure the effectiveness of these new treatments and techniques. Photonumeric rating scales have been developed to objectively assess improvements in anatomical areas; however, these have been based on the features of Caucasian patients. OBJECTIVE: To develop and validate a Chin Projection Scale for use in the female Asian patient population. METHODS AND MATERIALS: During 2 validation sessions, 13 raters assessed full frontal and lateral facial views of 50 Asian subjects and also estimated their age and the aesthetic treatment effort required for each subject. Chin projection was rated on a scale from 0 (optimal) to 4 (very severely receding). RESULTS: Inter-rater reliability was 0.80 (substantial) for Validation Session 1 and 0.83 (almost perfect) for Validation Session 2. The results for Estimated Age and Estimated Treatment Effort were essentially the same. CONCLUSION: This study demonstrated the validity of the first photonumeric assessment scale for assessing the appearance of the female Asian chin. This new scale will provide a standardized measure of chin projection for Asian patients in clinical practice and clinical research settings.

Validation of a Photonumeric Assessment Scale for Grading the Slope of the Asian Forehead.

BACKGROUND: As the number of aesthetic treatments has grown, so have the number of photonumeric assessment scales used to compare the effectiveness of these aesthetic treatments in specific anatomical areas; however, these are primarily based on Caucasian features. OBJECTIVE: To assess the validity of the first aesthetic scale for assessing the slope of the Asian forehead. A secondary objective was to correlate this scale with subject demographics and baseline characteristics. METHODS: During 2 validation sessions, 13 raters assessed full frontal and lateral facial images of female (n = 28; 56.0%) and male (n = 22; 44%) subjects. For each subject, the severity of forehead sloping was graded from 0 (convex forehead, optimal forehead volume) to 4 (concave forehead, very severe sloping). Raters also assessed the age of each subject and the estimated aesthetic treatment effort required to treat each subject. RESULTS: Inter-rater reliability was "substantial" with scores of 0.67 and 0.68 for the first and second validation sessions, indicating high reliability. BMI showed the highest correlation with the scale and was a significant predictor in the final regression model. CONCLUSION: This photonumeric assessment scale will be useful for assessing the slope of the Asian forehead in both clinical and research settings.
