Background and Objectives: There is a wide diversity of opinions regarding the management of delayed inflammatory reactions (DIRs) secondary to hyaluronic acid (HA)-based fillers. The plethora of approaches has led the authors to conduct a review regarding management and treatment of DIRs as well as establish therapeutic guidelines for this purpose. Materials and Methods: A review of the literature was performed through databases such as PubMed using keywords including HA-fillers and complications, delayed HA filler sequelae and therapy, soft tissue and dermal filler reactions and management. Additionally, a survey comprised of questions regarding the management and treatment of DIRs was sent to 18 physicians highly experienced with soft-tissue filler injections in 10 countries. Their answers and recommendations were analyzed and debated amongst these panelists. Results: Sixteen panelists favored antibiotic therapy as first-line treatment for DIRs, specifically dual antibiotic therapy consisting of a fluoroquinolone along with a tetracycline or macrolide for a period of 3-6 weeks. The majority refrained from the use of intralesional (IL) or systemic steroids except in the case of disfiguring or recalcitrant reactions. IL hyaluronidase was recommended by 13 panelists; however, some preferred a watchful waiting approach for a period of 48 hours to 2 weeks prior to IL hyaluronidase, and in cases where antibiotics did not lead to improvement. Conclusion: A consensus was reached and summarized to propose a clear, easy-to-follow, stepwise algorithm for the treatment of DIRs.
Although direct extrapolation from cadavers to the in vivo situation cannot be made, cannulae showed more precision in placement of product. With the sharp needle, the material was injected on the periosteum, and then migrated in a retrograde direction along the trajectory of the needle path, ending up in multiple anatomic layers. The sharp needle technique also showed a higher complication risk with intra-arterial injection occurring, even though the needle tip was positioned on the periosteum and the product was injected with the needle in constant contact with the periosteum.
Background:Hyaluronic acid is an ideal facial filler, however, although established as both safe and effective, complications do occur. Treatment recommendations that combine both expert opinions and clinical trial data are currently lacking, partly due to difficulties with diagnoses, nonspecific diagnostic investigations, and certain disorders presenting with similar symptoms, thereby confounding diagnosis and treatment.Methods:The purpose of this article was to provide the aesthetic clinician with practical recommendations regarding complication diagnosis arising as a consequence of hyaluronic acid filler rejuvenation treatment. It also provides recommendations for their management using step-wise treatment algorithms that are based on published expert opinions, as well as the author’s clinical experience.Results:Algorithms are provided for the most common categories of complication associated with hyaluronic acid filler treatment, that is, skin discoloration, edema, nodules, infection, and vascular compromise.Conclusions:These guidelines are not intended to be complete or exhaustive but may prove informative for aesthetic clinicians who are responsible for treating patients with hyaluronic acid fillers. It may help to guide them on recognizing potential complications and it provides clear guidance on optimum treatment pathways.
Introduction: Skin revitalizers are used for skin quality improvement purposes.Hyaluronan hybrid cooperative complexes (HCC, Profhilo®, IBSA Pharmaceuticals) are an anti-aging treatment with a large amount of pure hyaluronic acid (HA) based on stable, cooperative, and hybrid complexes. Cohesive polydensified matrix Hyaluronic Acid (CPM-HA20, Belotero Revive®, Merz Pharmaceuticals GmbH) is a slightly crosslinked HA (20 mg/ml) with glycerol (17.5 mg/ml). Aims:To evaluate the performance of HCC and CPM-HA20G for skin quality improvement in healthy female subjects. Methods:This was a split-face, single-blinded study that enrolled 24 healthy female subjects. Injections were given on three separate occasions. HCC was injected on the right cheek, while CPM-HA20G was injected on the left cheek. A battery of skin property measurements was used to evaluate the skin. Skin properties and overall satisfaction were analyzed using mixed models with the values at baseline, at week 1, week 8, and week 14 as an outcome and a random effect of subject and fixed effects of treatment, visit, and the treatment by visit interaction.Results: Both products showed evidence of effect relative to baseline on surface hydration (AU), elasticity (N/m) TEWL (g/m 2 h), and melanin (AU). CPM-HA20G also showed significant evidence of effect relative to baseline on water content (%), and HCC on pore count (n) and hemoglobin (AU). Satisfaction reported by the subjects themselves showed positive trends of satisfaction over time for multiple skin properties. There were no significant differences between the tested products in the observed skin characteristics over time. Conclusion:These devices are effective and safe treatments for skin quality improvement, especially moisturization, with high patient satisfaction and generally mild and transient side effects.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
