Higher Responder Rates Observed With Live Participant Assessment Versus Photographic Assessment After VYC-20L Hyaluronic Acid Treatment for Chin Augmentation

BACKGROUND

In an evaluator-blinded, randomized controlled trial, the hyaluronic acid soft-tissue filler VYC-20L injectable gel was safe and effective for correcting volume deficits and retrusion in the chin.

OBJECTIVES

The objective of this subanalysis was to compare responder rates obtained with photographic vs live assessments.

METHODS

Participants were randomized 3:1 to VYC-20L treatment or a 6-month, no-treatment control period followed by optional treatment. Responder rates (≥1-point improvement from baseline on the validated Allergan Chin Retrusion Scale [ACRS]) obtained with photographic assessments and live assessments at Month 6 were compared. Prespecified subgroup analyses compared responder rates by baseline ACRS severity, filler volume, cannula usage, and investigation site.

RESULTS

VYC-20L was effective for chin augmentation as evaluated with both live and photographic assessments. The ACRS responder rates at Month 6 were 91.8% with live assessments and 56.3% with photographic assessments. Consistently higher response rates were observed by live vs photographic assessment regardless of baseline ACRS severity, filler volume, cannula usage, and investigation site.

CONCLUSIONS

Live assessment of ACRS response after VYC-20L treatment resulted in higher responder rates than photographic assessment, supporting the use of live assessment for this indication to approximate real-world clinical practice.

Quantitative analysis of facial proportions and facial attractiveness among Asians and Caucasians

It has been proposed that the proportions of the human face are crucial for facial aesthetics. If this is the case, we should describe the relationship among proportions of face components quantitatively. This study aims to develop a mathematical model of facial proportions to provide a quantitative description of facial attractiveness. Furthermore, we expect that plastic surgeons can use models in clinical work to enhance communication efficiency between doctors and patients. Face alignment technique was used to analyse 5500 frontal faces with diverse properties (male/female, Asian/Caucasian, ages) to obtain the ratios among the nose length ($ {N}_{L} $), the nasal base width ($ N $), and the inner canthus width ($ {E}_{I} $). A mathematical model ($ {N}_{L}^{2} = a{E}_{I}\mathrm{*}{N}_{L}+b{E}_{I}\mathrm{*}N+cN\mathrm{*}{N}_{L} $) was developed to describe the relationship among these proportions. To validate the effectiveness of this approach, we simulated the post-operative photos using Adobe Photoshop. Our findings show that the ratio of nose length to nose width, the ratio of inner canthus width to nose length and the ratio of inner canthus to nose width play a significant role in determining facial attractiveness. These results provide a possible strategy to quantitatively describe the relationship among human face proportions.

Perception of cosmetic surgery and associated side effects: A content analysis study of South Korean female college students

ABSTRACT

This study explores the perception of female college students in South Korea regarding cosmetic surgery and its side effects.Face-to-face interviews were conducted with 28 female college students over a period of 4 months, starting in October 2019. All participants were female college students who had not undergone cosmetic surgery. The collected data were analyzed qualitatively, using conventional content analysis.Four categories and 13 subcategories were extracted from 112 meaningful codes reflecting perceptions related to cosmetic surgery and its associated side effects. The 4 categories that emerged in the study were: "reaction to the side effects of cosmetic surgery", "reasons for cosmetic surgery", "prospects of the participant's own cosmetic surgery", and "prerequisites for decision-making regarding cosmetic surgery".The results of this study could be used as reference material by surgeons to ensure safer cosmetic surgeries. A sufficient consideration period and patient education prior to selective cosmetic surgery would minimize patient complaints and expand the base of safe cosmetic surgery.

What is Beauty?

PURPOSE

In the current study, the authors attempt to thoroughly investigate the concept of beauty from different perspectives in different historical periods and offer their personal thoughts about it.

METHODS

The authors performed a comprehensive and across-the-board literature review about 'beauty', including beauty from a philosophical perspective, beauty perception by human mind, beauty from a biopsychological perspective, beauty of the face, body and breast, models of beauty and beauty in cosmetic surgery.

RESULTS

From Plato to modern neuro-psychological studies, the concept of beauty has always been a theme for adamant debates and passionate thoughts. Different aspects of beauty, from intellectual to pure physical, have received a tremendous amount of attention. The true definition of the concept of beauty is still ambiguous, and there is not a unanimous explanation for it. It seems that the definition of beauty differs in every individual's mind and over the history of humankind.

CONCLUSION

Although beauty is a very important concept and the seek for achieving it is a very natural behavior, one must remember that the importance of beauty should not overshadow the fact that every human being is made up of similar internal organs. We strongly encourage the reader to look beyond the hedge, to be aware that each of us is made up of internal organs, beyond the external appearance.
