Abstract
The use of hyaluronic acid-based soft tissue fillers has often been reported to modulate the muscle, that is, to cause myomodulation. To our knowledge, there has been so far no scientific study investigating the potential of hyaluronic acid-based soft tissue fillers to modulate or actually alter the function of facial muscles. To further assess this three-dimensional (3D) surface imaging and electromyography (EMG)-based prospective study investigated the changes of facial muscle contraction after injection of strategically placed hyaluronic acid-based soft tissue fillers to assess the actual validity of the term myomodulation. A total of 13 subjects with a mean age of 37.8 years (12 females, 1 male) were injected according to a predefined injection protocol. Surface EMG and 3D surface imaging were performed prior to the injection and 5 days after the injection. The results showed no significant change in the strength of the muscles (measured in μV) after injection of hyaluronic acid-based soft tissue fillers. However, horizontal and vertical skin displacement upon contraction of the zygomaticus major muscle changed significantly between baseline and follow-up, with a mean horizontal skin displacement increase from 3.2 to 4.1 mm. Upon contraction of the depressor anguli oris muscle, the horizontal skin displacement did not change significantly (2.15 vs. 2.05 mm), while vertical skin displacement increased significantly from 2.9 to 4.3 mm. The modification of the surrounding tissue caused an alteration of the vectorial skin displacement upon contraction of the muscle. A potential explanation could be the increased distance between the origin and insertion of the muscle due to the material deposition in the proximity of the relevant facial muscles, leading to a change of contraction vector.

Abstract
Botulinum neurotoxin type A (BoNTA) and filler injection procedures usually provide predicted outcomes with a low incidence of complications. Most of the complications after these procedures have been extensively discussed. In this study, we report on these injectables' less well-known, recently reported, and novel complications and attempt to clarify the underlying mechanisms. Counterfeit or mishandled BoNTA has been associated with botulism. BoNTA has been linked to uncommon complications, including morphea-like lesions, nontuberculous mycobacterial infections, vascular occlusion, and pseudoaneurysm of the superficial temporal artery. Unusual complications from filler injection include nonscarring alopecia, intraoral necrosis, nontuberculous mycobacterial infections, xanthelasma-like reactions, intracranial perforation, and pneumosinus dilatans. Post-BoNTA injection nodules and filler infection from bone destruction due to cocaine use are new complications. These complications pose a challenge for diagnosis and treatment. This publication aims to assist in promptly identifying and managing these rare and novel complications when necessary.

Abstract
BACKGROUND The measured intraarterial volume of cadaveric ophthalmic arteries was utilized for safety recommendations during facial soft tissue filler injections. However, its clinical practicability and model applicability have become questionable. OBJECTIVES To measure the volume of the ophthalmic artery in living individuals by utilizing computed tomography (CT) imaging technology. METHODS A total of 40 Chinese patients (23 males, 17 females) were included in this study with a mean age of 61.0 (14.2) years and a mean body mass index of 23.7 (3.3) kg/m2. Patients were investigated with CT imaging technology to evaluate the length, diameter, and volume of the bilateral ophthalmic arteries as well as the length of the bony orbits, resulting in a total of 80 investigated ophthalmic arteries and orbits. RESULTS Independent of gender, the average length of the ophthalmic artery was 80.6 (18.7) mm, the calculated volume of the ophthalmic artery was 0.16 (0.05) mL and the minimal and maximal internal diameter of the ophthalmic artery were 0.50 (0.05) mm and 1.06 (0.1) mm, respectively. CONCLUSIONS Based on the results obtained from the investigation of 80 ophthalmic arteries it must be concluded that current safety recommendations should be reevaluated. The volume of the ophthalmic artery appears to be 0.2 mL rather than 0.1 mL as previously reported. In addition, it appears impractical to limit the volume of soft tissue filler bolus injections to 0.1 mL due to the aesthetic requirements of each individual patient and treatment plan.

Abstract
Background Temporal filling is commonly used to correct temporal depression. However, there is a lack of quantitative criteria for pre- and post-operative evaluations. The use of three-dimensional scanning may help improving the success of temporal filling by providing quantitative assessments. The study aimed to compare the results of qualitative morphological evaluation of the temporal region with a quantitative, numerical analysis of the temporal difference value (TDV). Methods We enrolled twenty-six male and forty-nine female volunteers aged 18 to 29 years. Facial images were acquired in OBJ format using 3dMD facial stereo-photography. The morphologies of the temporal regions were separately evaluated by four researchers in the form of two-dimensional (2D) images. Results were classified as either aesthetic or unaesthetic. The quantitative evaluation of the temporal region was then conducted. First, the temporal region was trimmed out from the original 3D image into a new OBJ file. Second, interpolation was used to construct a smooth, adapted surface. Third, a mathematical model of temporal region flatness denoted as the TDV, which was defined as the sum of the Euclidean distances of all 3D points between the constructed surface and the temporal-region OBJ file. The classification of each sample was compared with its TDV to verify the mathematical model's validity. The cutoff threshold and prediction accuracy of this mathematical model were calculated. Results The cutoff threshold between aesthetic and unaesthetic TDV was found to be 24.66 for males and 28.11 for females. The prediction accuracy rate was 0.73 for men and 0.73 for women. Conclusion The method has high overlap and good repeatability and minimizes the influence of subjective aesthetics on morphological judgment. TDV has a certain reference value for clinical temporal region evaluation.

Abstract
BACKGROUND The Hispanic/Latin American population is the fastest growing non-Caucasian group in the United States. Within this group, demand for aesthetic procedures is on the rise. High ethnic variability among these patients influences treatment approaches and patient priorities. Understanding these ethnic differences is central to providing optimal care. AIMS To discuss similarities and differences in anatomy and treatment preferences of Hispanic/Latin American patients both within the United States and internationally and explore how these differences may influence or inform aesthetic practices. PATIENTS/METHODS In support of clinicians who wish to serve a diverse patient population, a 6-part, international roundtable series focused on diversity in aesthetics was conducted from August 24, 2021 to May 16, 2022. In this roundtable, held in Medellin, Columbia, expert clinicians from across Latin America and the United States were invited to contribute and share best practices. RESULTS The results of the second roundtable in the series, the Latin American Patient, are described here. A special emphasis is placed on procedures that address the most commonly encountered concerns in these patients. CONCLUSIONS Hispanic and Latino patients represent a broad demographic with unique anatomical features, aesthetic preferences, and treatment priorities. Clinicians should consider these differences when treating this patient population.

Abstract
BACKGROUND Previous clinical and anatomic investigations have identified the clinical relevance of facial biomechanics. Based on this new understanding, principles for facial aesthetic procedures were established: Lateral Face First, Deep Layers First, and Upper Face First. OBJECTIVE To test the upper face first principle by showing that an injection sequence, starting in the upper face is superior to an injection sequence starting in the lower face. METHODS This study was designed as an interventional split-face study administering the same amount and type of soft tissue filler for the upper, middle, and lower face but in a different sequence: upper, middle, lower face versus lower, middle, and upper face. A total of 15 patients (5 males and 10 females) with a mean age of 39.4 years (9.6) and a mean BMI of 23.4 kg/m2 (1.7) were studied. Follow-up at D0, D30, and D90 was conducted utilizing semiquantitative scores and objective 3D imaging. RESULTS Despite not reaching statistical significance, midfacial volume and jawline contouring were rated better at every follow-up visit (D0, D30, D90) when treated with the upper versus the lower face first injection algorithm. The global aesthetic improvement scale showed statistically significantly better values for the upper face first algorithm when compared to the lower face first algorithm at all evaluated time points with all p < 0.001. CONCLUSION Applying the upper face first injection algorithm seems to result in better aesthetic outcomes when directly compared to the lower face first algorithm. Semiquantitative and objective outcome measurements confirm its clinical effectiveness.

Abstract
BACKGROUND Adverse vascular event management following hyaluronic acid-based aesthetic injections relies on the administration of hyaluronidase which is capable of enzymatically degrading the injected product and improving clinical symptoms. Two protocols are currently available to manage such complications: "ultrasound-guided targeted" and "flooding". OBJECTIVES The aim of this study was to compare the 2 protocols in terms of the volume of hyaluronidase utilized, and the onset and degree of clinical improvement. METHODS A comparative case series of 39 patients was retrospectively evaluated. The patients were initially treated with the "flooding" protocol and then treated with the "ultrasound-guided targeted" protocol due to no or little improvement. RESULTS The "ultrasound-guided targeted" protocol utilized a mean [standard deviation] total of 122.5 [34] IU of hyaluronidase, whereas the "flooding" protocol utilized 1519.4 [1137] IU, which represents a statistically significant reduced amount of injected hyaluronidase (P = 0.028). There was no clinical improvement in 92.3% and only little improvement in 7.7% of the treated patients following the first applied "flooding" protocol, but there was a 100% immediate improvement when subsequently treated with the "ultrasound-guided targeted" protocol. Ultrasound imaging revealed that the application of hyaluronidase restored normal blood flow both in the perivascular space and in the superficially located subdermal soft tissues. CONCLUSIONS Despite its limitations in study design, this retrospectively evaluated case series revealed that the "ultrasound-guided targeted" protocol utilized less hyaluronidase and restored clinically visible symptoms faster. The effect of this protocol is best explained by the perforasome concept which will need to be investigated further in future studies. LEVEL OF EVIDENCE: 4

Abstract
Abstract
Background
Placement of fillers in close proximity to the mimetic or sphincter muscles of the face appears to enhance or suppress muscle action in a relatively predictable way.
Methods
From June 2016 to June 2021, patients who underwent the first author’s technique of myomodulation with dermal fillers to address aesthetic concerns or to manage facial spasms or synkinesis were evaluated in a retrospective case series. Additionally, the authors provide a technical guide for a whole-face approach to treatment with fillers and a conceptual map for treatment of each facial subunit with a focus on myomodulation.
Results
A total of 1352 patients (1108 women, 244 men; mean age, 51 years) underwent at least 1 treatment session during the 5-year study period. The treatment patterns of the study population and details of 2 representative cases are presented.
Conclusions
Although not well understood mechanistically, myomodulation with injectable fillers shows promise for significant and reliable results of facial rejuvenation.

Abstract
INTRODUCTION The anatomical complexity of the temporal region makes it so treatments with fill-ins are challenging due to high vascular risk. Techniques which provide safer procedures must be encouraged. GOAL Suggest access to the temple through the inferolateral orbital region as a means for safer temporal fill-ins. METHODS The fanning technique was plotted out not only via the conventional access (pretragal) but via the proposed one as well. The superficial temporal artery (STA) was mapped with ultrasound. The angles for each of the five retroinjection vectors were calculated in relation to STA and their mean was extracted. The longitudinality of the vector in regard to the vessel was considered the least safe factor. RESULTS The mean injection angle towards the artery was a 35-degree angle for the conventional access technique and a 73-degree angle for the inferior-lateral orbital access technique (p < 0.05). The more a degree is tangential to the vessel, the higher the chances for inadvertent puncture due to small technical issues. The safety of the procedure through the inferolateral orbital access is corroborated with blind ultrasound imaging done in real-time by radiologists. CONCLUSION The suggested access is shown to be comparably safer from a vascular perspective than the conventional pretragal access.

Abstract
The number of soft tissue filler injections performed by aesthetic injectors has continued to increase over the last few years. To provide a high standard of safety and achieve individualized, reproducible, and long-lasting outcomes, aesthetic injectors must have a solid foundation in anatomy, facial biomechanics, rheology, and injection biomechanics. Adverse events associated with soft tissue filler injections can be severe, especially if the aesthetic injector unintentionally injects the soft tissue filler into the patient's arterial vascular circulation and the administered product reaches the arterial bloodstream. Although the face has a rich arterial vascular supply that may seem overwhelmingly complex, it can be broken down systematically according to its internal and external vascular territories. To provide guidance for aesthetic practitioners performing minimally invasive facial injections for aesthetic purposes, this narrative article will discuss the course, depth, and branching pattern of the facial arteries based on the most frequently injected anatomical regions. In this article, we focus on vascular safe zones rather than danger zones .

Abstract
The number of soft tissue filler injections performed by aesthetic injectors has continued to increase over the last few years. To provide a high standard of safety and achieve individualized, reproducible, and long-lasting outcomes, aesthetic injectors must have a solid foundation in anatomy, facial biomechanics, rheology, and injection biomechanics. Adverse events associated with soft tissue filler injections can be severe, especially if the aesthetic injector unintentionally injects the soft tissue filler into the patient's arterial vascular circulation and the administered product reaches the arterial bloodstream. Although the face has a rich arterial vascular supply that may seem overwhelmingly complex, it can be broken down systematically according to its internal and external vascular territories. To provide guidance for aesthetic practitioners performing minimally invasive facial injections for aesthetic purposes, this narrative article will discuss the course, depth, and branching pattern of the facial arteries based on the most frequently injected anatomical regions. In this article, we focus on vascular safe zones rather than danger zones.

Abstract
OBJECTIVE Quantifying 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 METHODS A medical team created a novel 5 - point photonumeric scale. 12 international raters were involved in the digital validation, while 5 raters performed a live validation. RESULTS For 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. CONCLUSION The created scale to assess dorsal hand atrophy have 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.

Abstract
BACKGROUND Our understanding of the functional anatomy of the face is constantly improving. To date, it is unclear whether the anatomic location of the line of ligaments has any functional importance during normal facial movements such as smiling. OBJECTIVES The authors sought to identify differences in facial movements between the medial and lateral midface by means of skin vector displacement analyses derived from 3-dimensional (3D) imaging and to further ascertain whether the line of ligaments has both a structural and functional significance in these movements. METHODS The study sample consisted of 21 healthy volunteers (9 females and 12 males) of Caucasian ethnic background with a mean age of 30.6 (8.3) years and mean BMI of 22.57 (2.5) kg/m2. 3D images of the volunteers' faces in repose and during smiling (Duchenne type) were taken. 3D imaging-based skin vector displacement analyses were conducted. RESULTS The mean horizontal skin displacement was 0.08 (2.0) mm in the medial midface (lateral movement) and was -0.08 (1.96) mm in the lateral midface (medial movement) (P = 0.711). The mean vertical skin displacement (cranial movement of skin toward the forehead/temple) was 6.68 (2.4) mm in the medial midface, whereas it was 5.20 (2.07) mm in the lateral midface (P = 0.003). CONCLUSIONS The results of this study provide objective evidence for an antagonistic skin movement between the medial and lateral midface. The functional boundary identified by 3D imaging corresponds to the anatomic location of the line of ligaments. LEVEL OF EVIDENCE: 4

Abstract
OBJECTIVE The 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 METHODS Two 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. RESULTS For 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. CONCLUSION The 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.

Abstract
OBJECTIVE The 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 METHODS Three 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. RESULTS The 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. CONCLUSION The 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.

J Cosmet Dermatol 2021; 21:1464-1470. [PMID: 34731521 DOI: 10.1111/jocd.14555] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/12/2021] [Revised: 08/11/2021] [Accepted: 09/27/2021] [Indexed: 02/01/2023]
Abstract
OBJECTIVE To the knowledge of the authors, no data about the reproducibility and accuracy of 3-dimensional surface imaging of the face using a whole-body scanner are available. Thus, the objective of this investigation was to assess the reproducibility of facial scans acquired using a whole-body imaging device. MATERIAL AND METHODS This investigation investigated 220 3-D scans of a total of 22 healthy volunteers (with a mean age of 29.36 years). Two consecutive 3-D images using a Vectra WB360 of the volunteers were obtained utilizing a whole-body imaging device. Predefined distances in the face were performed in each scan and compared. Furthermore, surface deviation between two consecutively captured scans was assessed. RESULTS The distance with the smallest statistical significance was found to be at the nose with p = 0.998, while the biggest statistical significance was found in the midface with p = 0.658. The area with the biggest surface deviation between the superimposed scans was the neck with a root mean square (RMS) of 1.62 ± 1.71, and the area with the smallest surface deviation was the forehead with a RMS of 0.17 ± 0.05. CONCLUSION The whole-body imaging device investigated in this study can be utilized to capture the face and provides enough accuracy to compare scans. Even though not directly investigated, it can be hypothesized that the error caused by repositioning the patient between a baseline and a follow-up scan will not be too big to consider measurements performed with the whole-body imaging device as impractical.

Soft tissue filler augmentation of the orbicularis retaining ligament to improve the lid-cheek junction. J Cosmet Dermatol 2021; 20:3446-3453. [PMID: 34679226 DOI: 10.1111/jocd.14495] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/27/2021] [Revised: 08/27/2021] [Accepted: 09/16/2021] [Indexed: 12/14/2022]
Abstract
BACKGROUND The orientation of facial ligaments changes with increasing age due to the loss of bony support. Soft tissue filler injections placed in close proximity to facial ligaments can alter their orientation to help achieve an improved and younger aesthetic appearance. OBJECTIVE To assess the anatomic and aesthetic effects of a standardized injection with soft tissue filler placed directly inferior to the orbicularis retaining ligament in the infraorbital region. METHODS A total of 163 patients with signs of infraorbital aging were treated with a standardized soft tissue filler injection into and in close proximity to the orbicularis retaining ligament (ORL). 2D frontal images of the infraorbital region were rated by eleven blinded and independent raters with regards to the aesthetic appearance of the infraorbital region before and after the standardized injection treatment. RESULTS The aesthetic appearance of the entire infraorbital region (lid-cheek junction) was rated before and after the treatment. The severity of the tear trough (medial aspect of the infraorbital region) as well as the hollowing of the lateral aspect of the infraorbital region also was rated before and after the treatment. Aesthetic improvement was statistically significant when evaluated by the blinded raters, the treating physician, and the patients. All the results were "very much improved" compared to baseline. CONCLUSION The effectiveness of this injection technique is thought to be due to the strategic placement of soft tissue filler that helps to reposition facial ligaments that have changed their orientation during the aging process.

A prospective open-label, multicentre study evaluating a non-cross-linked hyaluronic acid based soft-tissue filler in the correction of lateral canthal and perioral lines. J Cosmet Dermatol 2021; 21:191-198. [PMID: 34559948 DOI: 10.1111/jocd.14460] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/16/2021] [Revised: 08/28/2021] [Accepted: 09/02/2021] [Indexed: 12/16/2022]
Abstract
OBJECTIVE The aim of this investigation was to assess the effectiveness of a non-cross-linked hyaluronic acid based soft-tissue filler in the correction of lateral canthal lines and periorbital lines. MATERIAL AND METHODS A total of 59 female Caucasian patients with a mean age of 52.6 ± 9.0 years were enrolled in this prospective open-label, multicentre study and received intradermal injections of a soft-tissue filler at baseline, after 3 and 6 weeks. Aesthetic improvement and patient satisfaction, skin hydration, skin firmness and skin elasticity, as well as adverse events were assessed at 3, 6, 8, 12 and 16 weeks. RESULTS At baseline, the lateral canthal skin firmness was 0.206 ± 0.07 mm and increased after 8 weeks to 0.087 ± 0.08 mm with p < 0.001, while the perioral skin firmness was 0.205 ± 0.09 mm and increased after 8 weeks to 0.116 ± 0.08 mm with p < 0.001. Increases in skin hydration were observed after 8 weeks in both areas, however, did not reach statistical significance at any point. At week 8, 12 and 16 a majority (93.1%, 91.1% and 73.7% respectively) of the patients stated that they were 'satisfied' or 'very satisfied' with the treatment. CONCLUSION Overall, the skin firmness and skin visco-elasticity showed significant increases in the lateral canthal and perioral region. Moreover, albeit not statistically significant, skin hydration increased in both areas after 8 weeks. The procedure has been shown to be safe and satisfactory for the treated patients; however, emergence of oral herpes should be added to the safety profile of intradermally applied hyaluronic acid treatments.

Abstract
BACKGROUND The temporal lifting technique can provide lateral facial lifting when administering hyaluronic acid (HA)-based soft tissue fillers into the subdermal plane of the temple. However, the central facial oval is not influenced by this technique. OBJECTIVES To identify the safety and esthetic effectiveness of additional midfacial injection points (in addition to the temporal lifting technique) that can volumize the medial midface, lift the lateral face, and increase jawline contouring when included into a full-face injection algorithm. METHODS The patient records of nine consecutive patients (all females) with a mean age of 35.0 (8.4) years and a mean body mass index of 21.7 (2.4) kg/m2 were retrospectively analyzed after a full-face injection algorithm was performed using HA-based fillers. The additional injection points target the supraperiosteal plane of the medial zygomatic arch, the lateral infraorbital region, and the pyriform fossa using both needles and cannula. RESULTS No adverse events were observed during the 6-month retrospective observational period. The volume of the medial midface increased, the volume of the lateral midface decreased, and the contour of the jawline improved; all effects reached a highly statistically significant level with p < 0.001. CONCLUSION Despite each individual injection is currently performed on a daily clinical basis the evaluated injection algorithm following the temporal lifting technique shows some evidence that it is safe and esthetically effective. Future studies will need to confirm the results presented herein in a larger sample and with objective outcome measures to guide safe and effective esthetic outcomes.

Abstract
BACKGROUND A 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. OBJECTIVE To 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 METHODS A 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. RESULTS A 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. CONCLUSION Temporal soft-tissue filler injections are safe and provide long-lasting aesthetic improvement both in pre- and postmenopausal women.
