Abstract Background 2D baseline and follow-up clinical images are potentially subject to inconsistency due to alteration of imaging parameters. However, no study to date has attempted to quantify the magnitude by which such images can be influenced. Objective The objective of the present study is to identify the magnitude by which images can be influenced by changing the imaging light angle. Methods This study is based on the evaluation of 2D frontal images of the face and included a total of 51 subjects of which n = 14 were males and n = 37 were females. Faces were photographed at 0°, 30°, and 60° light angle under identical and standardized conditions. Images were randomized and rated by 27 blinded raters for age, facial attractiveness, body mass index (BMI), temporal hollowing, lower cheek fullness, nasolabial sulcus severity, and jawline contour. Results Facial attractiveness decreased, facial unattractiveness increased and the evaluated BMI (based on facial assessment) increased statistically significantly at 60°. The assessment of regional facial scores, i.e., temporal hollowing, lower cheek fullness, and jawline contour, showed no statistically meaningful changes both at 30° and at 60° light angle. Conclusion The results indicate that there might be an observed blind range in light angle (0°–30°) which does not influence facial assessment. Increasing the light angle past the threshold value to 60° might result in a statistically significant impact on facial perception which should be accounted for when documenting and/or presenting facial 2D images.

Abstract Background Upper arm liposuction mainly focuses on the posterolateral region, which may lead to a lack of harmony between the aspirated and unaspirated areas. In addition, the treatment effect of arm liposuction is often evaluated only by preoperative and postoperative photograph comparison and simple measurement; quantitative research on this topic is still lacking. Methods The multi-positional circumferential arm liposuction (MCAL) technique was proposed and applied to a total of 34 females in our hospital from 2017 to 2019. Three-dimensional data of 12 patients before the operation and after 2–3 months were collected and processed by 3D imaging, and the volume reduction rate was evaluated quantitatively. Results The MCAL method was successfully applied in the clinic, and its surgical effect was quantitatively studied. The mean follow-up time of 12 patients was (75.2 ±13.1) days, and the postoperative volume was significantly reduced. The postoperative volume of patients with type I, type II and type III decreased by (10.79 ±2.55)%, (17.25 ±3.02)% and (22.76 ±3.51)%, respectively. Conclusion Our new MCAL technique was successful, maximizing the esthetic results in upper limb contour refinements in the superficial fascial layer. The clinical efficacy of this proposed MCAL method was evaluated by CT and 3D digital technology, which provided further accuracy in demonstrating its effect on the shape of the arm.

Abstract Background Limited data are available describing effectiveness of combining the use of calcium hydroxylapatite (CaHA) and hyaluronic acid (HA). Methods The authors performed a retrospective chart review of patients injected with a premixed combination of CaHA and a cohesive polydensified matrix (CPM®) HA (CaHA:CPM-HA ) in the authors’ aesthetic practices. The midface and lower face were injected. Patients’ records were evaluated, and treatment results were scored using the Merz Aesthetics Scale for the jawline® (clinician rated, CR-MASJ). Adverse events were recorded. Results A total of 41 patients were included, all females with a mean age of 47.5 years (range 21–63 years). The mean CR-MASJ score improved from 2.12 at baseline to 0.68 at t = 3 months (SD = 0.69, 95% CI 1.28–1.60) and 1.27 at t = 12 months (SD = 0.74, 95% CI 0.43–0.74). 100% of the subjects had experienced a ≥1-point improvement in CR-MASJ score at t = 3 months, versus 85% at t = 12 months. No adverse events were reported. Conclusion The results of this study support the volumizing and lifting potential of the hybrid mix CaHA:CPM-HA for treatment of cheeks and jawline.

Abstract Background This study aimed to test a model in which Instagram images-based activities related to self, friends, and celebrities were associated with acceptance of cosmetic surgery via Instagram appearance comparison and body dissatisfaction. We predicted that Instagram use for images-related activities involving celebrities and self (but not friends) was associated with acceptance of cosmetic surgery both directly and indirectly. Methods The study participants were 305 Italian women (mean age, 23 years). They completed a questionnaire containing the Instagram Image Activity Scale, the Instagram Appearance Comparison Scale, the Body Shape Questionnaire-14, the Acceptance of Cosmetic Surgery Scale. A path analysis was performed in which the Instagram images-based activities were posited as predictors of the Instagram appearance comparison, body dissatisfaction and acceptance of cosmetic surgery, respectively. Results We found that only image-based activities related to celebrities and self were significantly related to acceptance of cosmetic surgery, whereas friends’ Instagram-related activities were not significantly related to this criterion variable. Moreover, the indirect effect of both Instagram self- and celebrities-images activities on acceptance of cosmetic surgery through Instagram appearance comparison and body dissatisfaction was significant. Friends’ Instagram images-related activities were not associated with acceptance of cosmetic surgery. Conclusions Overall, these findings provide information about the role that activities carried out on Instagram, appearance comparison and body dissatisfaction, play on the acceptance of surgery for aesthetic reasons among women. The study highlighted the importance for surgeons to consider some psychological aspects and the influence of sociocultural factors on the interest for cosmetic surgery.

Abstract Background Breast reconstruction is an important coping tool for patients undergoing a mastectomy. There are numerous surgical techniques in breast reconstruction surgery (BRS). Regardless of the technique used, creating a symmetric outcome is crucial for patients and plastic surgeons. Three-dimensional surface imaging enables surgeons and patients to assess the outcome’s symmetry in BRS. To discriminate between autologous and alloplastic techniques, we analyzed both techniques using objective optical computerized symmetry analysis. Software was developed that enables clinicians to assess optical breast symmetry using three-dimensional surface imaging. Methods Twenty-seven patients who had undergone autologous (n = 12) or alloplastic (n = 15) BRS received three-dimensional surface imaging. Anthropomorphic data were collected digitally using semiautomatic measurements and automatic measurements. Automatic measurements were taken using the newly developed software. To quantify symmetry, a Symmetry Index is proposed. Results Statistical analysis revealed that there is no difference in the outcome symmetry between the two groups (t test for independent samples; p = 0.48, two-tailed). Conclusion This study’s findings provide a foundation for qualitative symmetry assessment in BRS using automatized digital anthropometry. In the present trial, no difference in the outcomes’ optical symmetry was detected between autologous and alloplastic approaches. Level of evidence Level IV.

Abstract Background A major concern related to modern surgery is to evaluate and address the complications associated with breast enlargement using Aquafilling® injection. This study aimed to assess the effect of Aquafilling® injection on immune response in such patients. Methods For four patients who consulted a surgeon after receiving Aquafilling® injection, medical history of the patients was taken; based on imaging examinations, Aquafilling® was removed. Samples were processed for histopathological and immunohistochemical examination. For detecting tissue antigens in histopathological samples, monoclonal antibodies against CD3 (lymphocytes T), CD 20 (lymphocytes B), and CD68 (macrophages) were used. By analyzing the images, the number of immune cells (lymphocytes T, lymphocytes B, and macrophages) and immunohistochemical reaction area were semiquantitatively evaluated. Results Different clinical features were observed in each patient after receiving Aquafilling® injection. In samples obtained from four patients, lymphocytes T (CD3), lymphocytes B (CD20), and macrophages (CD68) tissue expressions were observed. Statistically significant variations in the number of lymphocytes B (CD20) and macrophages (CD68), and differentiation of immunohistochemical reaction area for lymphocytes T (CD3) and lymphocytes B (CD20) were observed. Conclusions Inflammation is elevated in patients who received Aquafilling® injection. Medical imaging should be carried out in all such patients even if there are no visible symptoms. Removal of Aquafilling® can reduce the inflammation and risk of neoplastic progression in the patients. The influence of time elapsed since Aquafilling® injection and intensity of immune response requires further validation.

Abstract Background Patients often seek aesthetic correction of facial deficiencies (e.g., lines and folds) that are rarely the underlying cause of dissatisfaction with their appearance. Use of a more holistic approach focused on improving the emotional messages of the face (e.g., looking less sad) may improve patient satisfaction with treatment outcomes. The MD Codes™ system was developed to increase clinician success rates by reducing variability in the technical aspects of hyaluronic acid (HA) filler treatment and focusing on addressing unfavorable emotional attributes of the face. Methods The MD Codes, or medical codes, represent specific anatomical subunits for injection of HA fillers. Each MD Code includes information regarding the target depth of injection, the proper delivery tool (needle or cannula) and delivery technique (e.g., aliquot, bolus, fanning), and the minimum product volume recommended to achieve visible, reproducible results (active number). During treatment planning, the appropriate MD Codes are selected using algorithms focused on lessening unfavorable facial attributes (a saggy, tired, sad, or angry look) and enhancing positive attributes (an attractive, younger, more contoured, or feminine [soft] or masculine look). Results Three case studies are presented to illustrate how the MD Codes and their algorithms were used to address sagginess, tiredness, and sadness in two women and one man. Conclusions MD Codes provide a universal symbolic language for reducing variability in injection technique. The platform provides user-friendly algorithms to help clinicians increase patient satisfaction by going beyond treatment of lines and folds and to focus on reducing unfavorable facial attributes.

AbstractBackground Horizontal neck wrinkle formation is gaining more attention among cosmetic practitioners and clients. To date, hyaluronic acid products are one of the most common treatment options for this aesthetic concern. However, different therapeutic strategies should be given to solve the problem due to multiple etiological reasons. Given that oxidative damage plays a critical role in neck wrinkle formation, anti-oxidative compounds are now considered by physicians when making a treatment plan. Aims To evaluate the efficacy and safety of a non-cross-linked hyaluronic acid filler in combination with L-carnosine in treating horizontal neck wrinkles. Methods Thirteen patients with a Wrinkle Assessment Scale (WAS) of 2–5 for horizontal neck wrinkles were treated with L-carnosine-containing non-cross-linked hyaluronic acid. Participants were followed-up for 3 months after treatment. The post-treated WAS scores evaluated by physicians were collected when patient satisfaction was surveyed. Any post-treatment adverse events were recorded. Results With a single injection of the above filler, the physician-evaluated WAS scores improved by at least one score at one month and the improvement kept consistent as far as three months after injection. According to the last follow-up visit, 11/13 patients were satisfied with the treatment effect of their neck wrinkle. Moreover, adverse events were rare after filler injection, except for local complications that were considered common reactions to the filler injection procedure. Conclusion The non-cross-linked hyaluronic acid filler containing L-carnosine is safe and effective for treating horizontal neck wrinkles.Level of Evidence IV This journal requires that authors assign a level of evidence to each article.

ABSTRACT Objective: To study the influence of black space between the maxillary central incisors on the aesthetic visual perception of the face, via eye-tracking and visual analogue scale (VAS). Methods: Black space between the central incisors was created, for both sexes, as follows: control, 1-mm black space, 2-mm black space and 3-mm black space. Ninety raters participated in this study, divided into three groups: 30 laypeople, 30 nonorthodontists, and 30 orthodontists. After the visual calibration of each observer, eight photographs were presented in the Ogama® software concomitant with the use of the hardware The Eye Tribe®. Ogama generated information depending on the eye-tracking of each rater, regarding the time until the first fixation, time of fixation, heatmap, scanpath, and total time of fixation, to evaluate the areas deemed to be of interest according to the raters. Later on, the VAS was used, where each rater evaluated the images in an album on a scale of zero to 10 points. Results: The eyes and mouth were the areas more often noticed by the raters according to the heatmaps, while no significant difference was observed in time until the first fixation between the three groups of raters (p> 0.05). However, regarding the time of fixation on the mouth, a significant difference was observed (p< 0.05) when comparing the three groups. Conclusion: Black space has a negative effect on the aesthetic perception of the face. The amount of attention on the mouth is correspondent to the size of the black space.

Abstract Objectives The face aging processes are associated with physiologic and biochemical alteration that produces wrinkles, skin pigmentation and benign growths. The aim of this study was to evaluate the clinical efficacy of voltaic arc dermabrasion with plasma to remove benign facial skin lesions. Study Design Voltaic arc dermabrasion plasma technique was used to remove the facial benign skin lesions. The study involved 45 patients (26 females;19 males) treated for benign facial skin lesions with voltaic arc dermabrasion also called plasma exeresis technique. The subjects age ranged between 43 and 65 years. The clinical observations and comparison of pretreatment and post-treatment photographs of the treated regions were performed by a joint examiner at each follow-up visit. Results During plasma irradiation, the average temperature of the skin was 290.3 ± 21.7 °C, while immediately after it was 90.6 ± 21.8 °C. Overall clinical improvement was 100% in six lesions with complete resolution of all lesions. Three patients observed a transient post-inflammatory pigmentation with a peak at 1 month after VAD treatment, gradually fading spontaneously over 2 to 3 months. Conclusions The voltaic arc dermabrasion technique (atmospheric plasma) should be considered for lesions, especially relatively superficial ones, and small lesions that are located on the face.

Abstract Background Aesthetic physicians and surgeons should consider differences in anthropometric and anatomical characteristics between Asians and Caucasians in performing facial rejuvenation procedures using absorbable threadlifts in Koreans. Objectives This paper was prepared to propose empirical treatment protocols for Korean aesthetic physicians and surgeons. Methods A panel of five Korean experts on the aesthetic uses of an absorbable polydioxanone (PDO) monofilament threadlift (Mint Lift®; HansBiomed Co Ltd., Seoul, Korea), thus termed as “the Mint Consensus Group,” was convened to recommend practical guidelines for empirical treatment with the Mint Lift®. Results To summarize, our recommendations are as follows: First, the entry and exit points should be determined considering anatomical characteristics of the face (Level of evidence III). Second, treatment procedures may vary depending on indications (Level of evidence III). Conclusions Here, we propose empirical treatment protocols for facial rejuvenation using a novel absorbable PDO monofilament threadlift in Koreans. But more evidence-based efforts should be made to update the current treatment protocols.
