RESUMEN

Including the jawline in aesthetic assessment has become increasingly popular when using both surgical and nonsurgical techniques. Facial aging processes include bone resorption, fat pad atrophy, and a breakdown of the quality of collagen and elastin in the skin. To provide optimal treatment of the jawline using nonsurgical techniques, it is important to consider all of these aspects before planning treatment. Men and women have different facial aging processes and ideal facial ratios that must be respected. The objective of this article is to discuss the use of botulinum toxin A and hyaluronic acid filler injectable treatments, deoxycholic acid injectable treatments, and cryolipolysis treatments and explain how these treatments can be utilized for optimal rejuvenation of the jawline and perioral area.

RESUMEN

BACKGROUND: Historically, soft-tissue hyaluronic acid (HA) fillers have been mixed with agents to reduce pain or alter physicochemical properties. OBJECTIVE: Evaluate the impact of dilution and mixing on HA filler physicochemical properties. MATERIALS AND METHODS: Crosslinked HA filler (VYC-20L, 20 mg/mL) was diluted to 15 mg/mL using saline through 5 or 10 passes between 2 syringes connected using a luer connector. Extrusion force, rheological properties, and microscopic appearance were assessed. Undiluted VYC-15L (15 mg/mL) served as the control. RESULTS: Average extrusion force was higher for diluted VYC-20L versus the control, with an increase in slope for gel diluted using 5 passes (0.65) and 10 passes (0.52) versus the control (<0.1). For diluted samples mixed with 5 or 10 passes, the rheological profile was different between the 2 halves of the syringe, with the second half more elastic than the first half, compared with the consistent profile of undiluted samples. Microscopically, diluted VYC-20L samples seemed more liquid near the luer and more particulate near the piston compared with the control, which was smooth throughout. CONCLUSION: In addition to potentially introducing contamination, diluting or mixing soft-tissue HA fillers yields a heterogeneous product with physicochemical characteristics that vary substantially throughout the syringe.

RESUMEN

BACKGROUND: There is a steady increase in publications about the use of ultrasound and filler treatments, written by physicians from different specialties. The terminology used to describe the ultrasound images of fillers is not uniform, making the different articles difficult to compare. Standardization of the descriptions based on their basic sonographic parameters is recommendable. AIMS: The purpose of this study is to propose a nomenclature for the sonographic description and reporting of cosmetic fillers. METHODS: An assessment of articles indexed for MEDLINE/PubMed and Embed electronic database was conducted; in total of 39 articles could be included. RESULTS: All articles were investigated for their sonographic descriptions of soft tissue fillers. Ten parameters used for describing and monitoring soft tissue fillers were distinguished. CONCLUSION: The proposed sonographic descriptions for cosmetic fillers may contribute to a better standardization and understanding fillers ultrasound images in the reports or literature.

RESUMEN

The periorbital area is the first area of the face to show signs of aging. To provide safe and natural looking rejuvenation of the delicate eyelids, and supporting structures, an advanced understanding of anatomy, ideal facial proportions, and the most effective methods for rejuvenation is discussed. Periocular rejuvenation is particularly challenging due to the intricate and delicate anatomy of the periocular area. To ensure safe and successful outcomes, it is crucial that injectors use a global approach when providing treatments and that they consider soft tissue, vasculature, and bone structure of the periocular region before administering treatments for aesthetic rejuvenation. Neuromodulators, specifically botulinum toxin A (BoNT-A), and hyaluronic acid (HA) dermal fillers are 2 nonsurgical treatments frequently used to address signs of aging in the periocular area. The objective of this article is to review different BoNT-A and HA filler treatments and discuss how these treatments can be used for optimal rejuvenation of the periocular area.

RESUMEN

BACKGROUND: Many noncollagen dermal fillers (NCDFs) have been approved by the FDA and are currently the second-most performed noninvasive cosmetic procedure. OBJECTIVE: To summarize and compare the clinical trials reviewed by the United States FDA in the approval of NCDFs. METHODS: The FDA Premarket Approval (PMA) site was queried, and the year of approval, indication, design, primary end points, touch-ups, retreatments, and study duration were extracted and tabulated. RESULTS: Twenty-one FDA-approved NCDFs from 2003 to 2018 and 24 Summary of Safety and Effectiveness documents were reviewed. Differences in the trial design and in reporting of data make comparisons difficult. This article provides comparative tables to make interpreting the various trial results more straightforward. LIMITATIONS: Primary efficacy end points and the way that filler volumes were reported varied by company. This article does not focus on secondary end points or safety data. CONCLUSION: A comprehensive and comparative review of clinical trials of NCDFs by the FDA demonstrates that differences in data reporting, especially for touch-ups and retreatments, make filler duration difficult to compare and interpret. Understanding of the trial design will allow the clinician to become more astute and allow for better management of patient expectations in clinical practice.

RESUMEN

The authors of this review present a comprehensive assessment of the techniques and indications in the treatment of the long upper lip. Setting aside the maxillofacial malformations, the review is focused on senescence as the most frequent etiology. A graphical reminder of the anatomical entities and of the upper lip proportions allows optimal preoperative planning. All current treatment options, from fillers to surgical excision and dermabrasion, are reviewed and summarized in order to provide an overview of each technique's expected results and contraindications.

RESUMEN

IMPORTANCE: The US Food and Drug Administration (FDA) recently issued a safety warning regarding soft-tissue fillers (STFs) based on the risk of blindness and facial necrosis. OBJECTIVE: To examine the quality of evidence leading to FDA approval of STFs. EVIDENCE REVIEW: All original approvals for STFs were mined using the publicly available FDA database. The Cochrane Collaboration's risk of bias assessment tool was applied to all randomized clinical trials (RCTs). FINDINGS: A total of 14 STF approvals were identified. Of those, 10 pivotal studies (71%) were RCTs and 9 (60%) were masked. The median number of patients per trial was 144 (range, 30-439). Eleven of 12 studies (92%) met their primary end point. Ten of 14 trials (71%) involved injections solely of the nasolabial folds or cheeks; only 4 trials involved treatment of other facial regions. All 10 RCTs had an unclear risk of selection bias. Only 2 RCTs reported exclusions and attrition. CONCLUSIONS AND RELEVANCE: Safety warnings relate more to the off-label use of STFs, which has not been sufficiently studied prospectively. Although STFs remain a safe device, with approval based mostly on RCT outcomes, implementation of unique device identifiers and greater use of physician-led registries would ensure physician, consumer, and regulatory confidence in STF safety.

RESUMEN

A lipoenxertia de face, apesar de consagrada, não é isenta de riscos e complicações. Neste relato de caso, descrevemos de forma inédita uma complicação isquêmica local, causada por enxerto de gordura. Simultaneamente, propomos a terapêutica com Oxigenioterapia Hiperbárica para o tratamento desta situação, não se limitando exclusivamente à gordura, mas principalmente ao PMMA, em que esta complicação é muito mais frequente.


Facial fat grafting is not devoid of risks and complications, despite being a widely practiced procedure. In this case report, we describe a novel form of local ischemic complication that occurred secondary to fat grafting. Simultaneously, we propose Hyperbaric Oxygen therapy for the treatment of this situation. We propose that Hyperbaric Oxygen therapy should not be limited solely to fat graft-related ischemia, but should be effective in the management of the more frequently encountered complications associated with polymethylmethacrylate fillers.
