AbstractObjectiveQuantifying the degree of dorsal hand atrophy is a challenging endeavor, but often necessary, in both the clinical and the research setting. The aim of this investigation was to create and consecutively validate a 5‐point photonumeric scale for assessment of dorsal hand atrophy.Material and MethodsA medical team created a novel 5‐point photonumeric scale. Twelve international raters were involved in the digital validation, while five raters performed a live validation.ResultsFor the digital validation of the Croma Hand Atrophy Assessment Scale, a total of 72 subjects (58 females, 14 males) with a mean age of 43.0 ± 14.4 years [18–73 years] were assessed. For the live validation, 88 subjects (73 females, 15 males) with a mean age of 45.0 ± 14.1 years [20–73 years] were rated. The results revealed almost perfect intra‐rater (ICC: 0.90 [95% CI: 0.88–0.92]) and inter‐rater agreements (ICC: 0.85 [95% CI: 0.81–0.89] and 0.86 [95% CI:0.82–0.89]) in the digital validation and substantial intra‐rater (ICC: 0.79 [95% CI: 0.75–0.82]) and inter‐rater agreements (ICC: 0.75 [95% CI: 0.68–0.81] and ICC: 0.67 [95% CI: 0.54–0.77]) in the live validation.ConclusionThe created scale to assess dorsal hand atrophy has been shown to provide substantial‐to‐almost perfect agreement in the digital and live validation cycles and reached comparable intra‐rater and inter‐rater agreement to already published and validated scales. It is expected that the created scale will help physicians and researchers in the assessment of hand atrophy in the clinical and research setting in the future.

AbstractObjectiveThe objective of this investigation was to create and to examine the reproducibility and validity of 5‐point photonumeric assessment scales that allow objective assessment of chin retrusion and jawline sagging using a digital and a live validation.Material and methodsTwo new 5‐point photonumeric scales created to assess chin projection and jawline sagging were validated by 12 experts in a digital validation and by 5 experts in a live validation setting. Intra‐rater agreement and inter‐rater agreement were assessed.ResultsFor the digital validation, an almost perfect intra‐rater (Kappa: 0.89 [95% CI: 0.86–0.91]) and almost perfect inter‐rater agreement in both sessions (Kappa: 0.80 [95% CI: 0.74–0.86] and 0.80 [95% CI: 0.74–0.86]) was achieved for the Croma Chin Projection Assessment Scale, while intra‐rater agreement (Kappa: 0.88 [95% CI: 0.85–0.91]) was almost perfect for the Croma Jawline Sagging Assessment Scale and inter‐rater agreement being substantial in the first session (Kappa: 0.76 [95% CI: 0.71–0.81]) and almost perfect in the second session (Kappa: 0.81 [95%CI: 0.76–0.85]). For the live validation, intra‐rater agreement was almost perfect for the Croma Chin Projection Assessment Scale (Kappa: 0.82 [95%CI: 0.74–0.90]) and the Croma Jawline Sagging Assessment Scale (Kappa: 0.83 [95%CI: 0.77–0.89]), while inter‐rater agreement was substantial in both sessions for both scales.ConclusionThe created chin and jawline photonumeric grading scales are valid and reliable tools for assessing chin projection and jawline sagging. The scales will be of value for standardized chin evaluation and quantifying outcomes in clinical research and daily practice.

AbstractObjectiveThe objective of this investigation was to create and validate 5‐point photonumeric scales for the assessment of dynamic crow's feet, static crow's feet, and infraorbital hollows.Material and methodsThree novel 5‐point photonumeric scales were created by a medical team. A total of 12 raters from all over the world performed a digital validation, and a total of 5 raters a live validation of the created scale.ResultsThe statistical analysis revealed almost perfect intra‐rater and inter‐rater reliability in the digital validation of the scales for the assessment of static and dynamic crow's feet as well as infraorbital hollows. In the live validation, both crow's feet scales showed almost perfect intra‐rater reliability, while the Croma Infraorbital Hollow Assessment Scale showed substantial intra‐rater reliability. Inter‐rater reliability was substantial for all three scales in the live validation. All three scales, the Croma Dynamic Crow's Feet Assessment Scale, Croma Static Crow's Feet Assessment Scale, and Croma Infraorbital Hollow Assessment Scale, were validated digitally and in a live setting.ConclusionThe created scales to assess infraorbital hollowing, dynamic and static crow's feet have been shown to provide substantial to almost perfect agreement in the digital and live validation and can thus be considered as helpful tools in the clinical and research setting. While technical methods and appliances to assess the degrees of severity of age‐dependent features are advancing, validated scales are of great importance due to their ease of use and, as shown by the validations, reliability, and reproducibility.

AbstractBackgroundMinimally invasive treatments as soft tissue filler injections can enhance the appearance of the jawline. This prospective, single‐center study investigated aesthetic outcome, patient satisfaction, adverse events, and volume changes after jawline contouring using standardized reporting scales and objectifiable 3D surface analysis.MethodsA total of 30 patients (1 male and 29 females, mean age: 57.2 (±8.7) years) were investigated. Patients underwent jawline augmentation using a highly cross‐linked hyaluronic acid–based soft tissue filler. Three‐dimensional surface imaging was performed after 2 weeks, and 3, 6, 9, and 12 months. Furthermore, the aesthetic results and the occurrence of complications were investigated after two weeks, and 3, 6, 9, and 12 months.ResultsThe surface‐volume coefficient (SVC) had an average of 1.10 ± 0.2 after 14 days, 0.95 ± 0.1 after 3 months, 0.83 ± 0.1 after 6 months, 0.74 ± 0.1 after 9 months, and 0.63 ± 0.1 after 12 months. A significant correlation was revealed between time of measurement and measured SVC with rp = −0.761, p < 0.001. Multivariate analysis revealed a significant difference between the measured SVC and the different time points of measurement with p < 0.001. The data revealed strong aesthetic improvement with results most often reported as “very much improved” according to the 5‐point GAIS after 3, 6, and 9 months, both by the investigator and by the patients. A 12‐month follow‐up analysis showed “much improved” results in a majority of cases.ConclusionThe result of this investigation showed that jawline enhancement using minimally invasive soft tissue filler injections produces durable, safe results that are generally rated as very satisfying from a patient's and investigator's perspective over a time period of 12 months.

AbstractBackgroundA plethora of age‐related changes contribute to hollowing of the temples, as bone remodeling, atrophy of the temporalis muscle, thinning of the skin, and deflation of the subcutaneous and deep temporal fat create the appearance of a skeletonized face. In addition, previous studies have established a relationship between facial skeletonization, temporal hollowing, and postmenopausal sarcopenia.ObjectiveTo compare the volume change, adverse events, and patient satisfaction of soft‐tissue filler injections in the temple between young (<51) and old (>51) females.Material and MethodsA total of 30 women with a mean age of 53.1 ± 12.1 years underwent bilateral temporal volumization. Adverse events and satisfaction were assessed after 3 and 6 months. 3‐Dimensional surface imaging was performed at baseline and after 2 weeks, 3 and 6 months to assess volumetric changes.ResultsA mean volume of 5.55 ± 1.9 cc was injected into the temples. A total of 31 adverse events were observed in 13 patients. The overall satisfaction of the procedure was very high after 3 and 6 months in both patient groups, and raters showed a significant agreement in their assessment of the aesthetic improvement, while the self‐reported patient satisfaction was also substantially high. The surface‐volume coefficient differed significantly between 14 days and 3 months post‐injection only in pre‐menopausal patients, while no significant difference was detected between 3 and 6 months.ConclusionTemporal soft‐tissue filler injections are safe and provide long‐lasting aesthetic improvement both in pre‐ and postmenopausal women.
