Patient factors influencing dermal filler complications: prevention, assessment, and treatment

Comparing the Effects of Different Injection Techniques Used in Lip Augmentation on Filler Migration and Patient Satisfaction

OBJECTIVE

Lip rejuvenation has several aims, including enhancing lip volume, adjusting the upper and lower lip's length, diminishing fine lines, contouring and redefining the cupid bow and vermilion border, and eversion of the vermilion. Within the scope of this research, we aimed to compare popular injection techniques to augment the size of the lips.

MATERIALS AND METHODS

This randomized retrospective study included 216 female patients aged 19 to 39, who desired a lip filler treatment from 2017 to 2023. Pre- and post-procedure results were elaborated with top-to-the-bottom technique in Group 1, bottom-to-the-top technique in Group 2, and lateral-to-medial techniques in Groups 3 and 4.Once the patients were sufficiently anesthetized, the hyaluronic acid at a concentration of 20 mg/mL with 0.3% (3 mg/mL) lidocaine, was used in all groups. Patients were followed up for three weeks. Patient satisfaction scores were evaluated on a scale from 0 to 5 using a survey on the last follow-up day.

RESULTS

A statistically significant difference was found between the groups regarding satisfaction scores (p<0.05). The patient satisfaction scores after injection were 4.78/5 in Group 1, 3.70/5 in Group 2, 4.15/5 in Group 3, and 3.85/5 in Group 4. Kruskal-Wallis variance analysis for more than two groups revealed statistically significant differences between Group 1 and Group 2 (p<0.001), Group 1 and Group 3 (p<0.001), Group 1 and Group 4 (p<0.001), and Group 2 and Group 3 (p=0.009) (Mann Whitney U-Test with Bonferroni adjusted). No major complication was observed in any of the patients.

CONCLUSION

In this study, patient satisfaction was found to be highest in the group with needle orientation top to bottom, taking into account migration to the upper lip. These findings showed that the direction of the needle during injection also determines the direction of distribution of the filler on the lip and may be an important factor in patient satisfaction.

Late-Onset Reactions after Hyaluronic Acid Dermal Fillers: A Consensus Recommendation on Etiology, Prevention and Management

Hyaluronic acid (HA) dermal fillers, generally considered low-risk, can lead to rare late-onset reactions (LORs) manifesting between 3 and 4 months postinjection, occasionally even as early as 24 h postinjection. The Complication Assessment and Risk Evaluation (CARE) board was established to review these reactions. In this publication, the authors aims to explore the etiological hypotheses underlying LORs, associated risk factors, prevention, and management approaches suggested by the CARE board. The CARE board identified three etiological hypotheses contributing to LORs. Firstly, the physicochemical structure of the filler, particularly low molecular weight HA, which may trigger an immune response. Secondly, infection, potentially introduced during injection or by dormant biofilm activation. Lastly, an imbalance in the host immune system, caused by factors like autoimmune diseases or viral infections, may lead to extended foreign body reactions, delayed type IV hypersensitivity, or adjuvant-based reactions. Based on these hypotheses, the board categorized various risk factors as patient-related (e.g., recent dental treatment, current medical status, active autoimmune disease), product-related (e.g., molecular weight), and procedure-related (e.g., aseptic technique and trauma). To reduce the risk of LORs, the CARE board recommends diligent patient selection, including comprehensive medical history assessment and informed consent. Practitioners should maintain an effective aseptic technique, and choose an appropriate product and injection depth for the anatomical location. Post-procedure, patients should receive education on proper filler care. Management of LORs depends on the suspected etiology, and the CARE board has proposed an algorithm to determine the most appropriate treatment. Hyaluronidase is recommended for noninflammatory reactions in the absence of active infection, while watchful waiting and/or steroid treatment may be preferred for inflammatory reactions. Hyaluronidase is not recommended as a first-line treatment for infections, which require drainage, bacterial culture, and antibiotic treatment. However, the board emphasizes the need for individualized evaluation and treatment in all cases.

Clinical and ultrasonographic evaluation of efficacy and safety of intralesional injection of autologous platelet-rich plasma in morphea: A comparative case series

Objective

To evaluate the efficacy and safety of platelet-rich plasma to restore skin changes in morphea by ultrasound and Localized Scleroderma Cutaneous Assessment Tool.

Methods

Nine morphea patients (21 lesions) were diagnosed clinically and by histopathology. Intradermal platelet-rich plasma was injected into morphea lesion once weekly for 12 sessions. The disease severity and damage were evaluated at baseline, after the last session (3 months later), and at 6 months follow-up using the LoSCAT and a high-resolution ultrasound. The healthy corresponding side was considered as a control.

Results

The Localized Scleroderma Cutaneous Assessment Tool score showed a significant improvement starting from 13 ± 7.28 up to 7.33 ± 6.82 after the therapeutic endpoint, reaching to 6.44 ± 7.09 after 6 months of follow-up with p value = 0.008 and 0.014, respectively. There was a significant positive correlation between the duration of the lesion and the improvement assessed by the ultrasound, with p value = 0.01. Regarding adverse effects, all patients reported having pain during platelet-rich plasma injection; transient edema of the face was reported by four patients (45%), and only two patients showed transient erythema.

Conclusion

Autologous platelet-rich plasma is a safe technique with great aesthetic outcomes for filling up the contour defects and correcting both hyper and hypopigmentation, in addition to softening the indurated lesions.

Causes and management of sight threatening complications of dermal filler injections: A review

Injectable dermal fillers continue to increase in popularity in aesthetic medicine. Although rare, vision loss secondary to filler injections is a devastating complication associated with a poor visual prognosis. The mechanism for vision loss is thought to be related to retrograde embolization of the dermal filler from peripheral vessels in the face into the ophthalmic arterial system. Early recognition and prompt management are essential if vision is to be salvaged. The use of retrobulbar hyaluronidase is still contentious, however when administered by a specialist, this treatment gives the best chance at visual recovery and should be considered for all cases.

Laser Speckle Contrast Imaging Guides Needling Treatment of Vascular Complications from Dermal Fillers

BACKGROUND

Although laser Doppler imaging (LDI) accurately delineates a hypoperfused area to help target hyaluronidase treatment, laser speckle contrast imaging (LSCI) is more appropriate for assessing microvascular hemodynamics and has greater reproducibility than LDI. This study investigated the use of LSCI in the evaluation and treatment of six patients who developed vascular complications after facial dermal filler injections.

METHODS

The areas of vascular occlusion were accurately defined in real time by LSCI and were more precise than visual inspections or photographic evidence for guiding needling and hyaluronidase treatment.

RESULTS

All patients had achieved satisfactory outcomes as early as Day 2 of treatment and no procedure-related complications were reported after a median follow-up of 9.5 (7-37) days.

CONCLUSION

LSCI accurately and noninvasively delineated vascular occlusions in real time among patients experiencing complications of facial dermal filler injections. Moreover, LSCI was more accurate than visual and photographic evaluations. Clinicians can use LSCI to reliably follow-up therapeutic outcomes after salvage interventions for vascular occlusions.

Safety of esthetic procedures in rheumatic patients: single-center survey of patients

The popularity of esthetic medicine is growing every year, also among patients with autoimmune inflammatory rheumatic diseases (AIRD). The objective of this study was to evaluate the safety of esthetic medicine (AM) procedures in patients with AIRD. A semi-structured, anonymous questionnaire regarding rheumatic and concomitant diseases and AM procedures was distributed among adult patients hospitalized in the rheumatology department or attending outpatient clinic in the National Institute of Geriatrics, Rheumatology, and Rehabilitation, Warsaw. The main outcome was the occurrence of an adverse event. A number of 512 patients took part in the survey and 15 were excluded (AM procedure preceded the diagnosis of AIRD). The study group consisted of 497 patients, of whom 47 had undergone AM procedures. The procedures performed included: tattooing (22 patients), piercing (16 patients), hyaluronic acid (7 patients), botulinum toxin (5 patients) injections, laser procedures (6 patients), plastic surgery (4 patients), mesotherapy (3 patients) and others. The vast majority of patients had these performed during remission or low disease activity. 70.2% of patients received treatment with disease-modifying antirheumatic drugs (DMARDs) during the AM procedure, with TNF-alfa inhibitors being the most common (63.6%). Adverse events occurred in 15% of patients. All were mild and transient site reactions. Most patients would like to repeat the AM procedure in the future. The use of esthetic medicine procedures in patients with AIRD, including those treated with biologic DMARDs, was associated with a risk of mild site reactions. Most of the patients expressed satisfaction with the results of the AM procedure.

Hyaluronidase for Dermal Filler Complications: Review of Applications and Dosage Recommendations

BACKGROUND

Hyaluronidase (Hyal) can reverse complications of hyaluronic acid (HA) fillers, which has contributed substantially to the popularity of such procedures. Still, there are differing opinions regarding Hyal treatment, including dosage recommendations in filler complication management.

OBJECTIVE

We aimed to address unanswered questions regarding Hyal treatment for HA filler complications, including timing and dosage, skin pretesting, properties of various Hyals and interactions with HA gels, and pitfalls of the treatment.

METHODS

PubMed and Google Scholar databases were searched from inception for articles on Hyal therapy for filler complications. Articles were evaluated regarding their contribution to the field. The extensive literature review includes international leaders' suggestions and expert panels' recommendations.

RESULTS

There are limited controlled data but increasing clinical experience with Hyal treatment. The currently used Hyals provide good results and have an acceptable safety profile. Nonemergent complications such as the Tyndall effect, noninflamed nodules, and allergic or hypersensitivity reactions should be treated with low or moderate Hyal doses. Hyal should be considered with prior or simultaneous oral antibiotic treatment in managing inflammatory nodules. Hyal may be tried for granulomas that have not responded to intralesional steroids. Emergent complications such as vascular occlusion and blindness require immediate, high-dose Hyal treatment. Regarding blindness, the injection technique, retrobulbar versus supraorbital, remains controversial. Ultrasound guidance can increase the efficacy of the above interventions.

CONCLUSIONS

Hyal is essential in aesthetic practice because it can safely treat most HA filler complications. Immediate Hyal treatment is required for emergent complications. Aesthetic practitioners should be versed in using Hyal and effective dosage protocols.

Management strategies for vascular complications in hyaluronic acid filler injections: A case series analysis

BACKGROUND

As hyaluronic acid (HA) filler injections have become increasingly popular in the esthetic field, so have their side effects. Vascular complications, which can lead to skin necrosis or permanent scarring, are a particularly dangerous complication and occur when the filler is injected directly into a blood vessel or when an adjacent blood vessel is compressed by the filler material.

OBJECTIVE

To assess the clinical prognosis based on post-procedural management and clinical findings of HA filler vascular complications.

METHODS

Herein, we present a case series of vascular complications due to HA filler and evaluate their clinical prognosis based on post-procedural management and clinical findings. Clinical assessments were performed using Doppler ultrasound, thermography, and laboratory tests.

RESULTS

Factors including white blood cell count, the time of treatment initiation, and time of hyaluronidase injection influenced the clinical outcomes. Early recognition and prompt hyaluronidase injection proved crucial in preventing further damage and improving prognosis.

CONCLUSION

This case series highlights the importance of early detection and appropriate management of HA filler complications. Physicians should be aware of the potential risks associated with fillers and promptly address any adverse effects to achieve optimal clinical outcomes. Further studies are warranted to confirm these findings and refine treatment strategies for the HA filler complications.

Polymethylmethacrylate Microspheres are Immunologically Inert in Mouse Tissues

Nowadays, aesthetic concerns have gained attention, especially by patients looking for a less invasive alternative to minor facial corrections. Polymethylmethacrylate (PMMA) is widely used as a soft tissue filler; the demand for this polymer has increased, and along with it, there are some reports of adverse reactions. Such adverse reactions stem from consequences of immune and inflammatory reactions to PMMA. Some animal models have been used to unravel the causes of these reactions, among other factors involving the management of PMMA. The aim of this study was to determine the immunogenic profile of PMMA implantation in different anatomical planes of mice, over up to 360 experimental days. In this study, BALB/c mice were divided into 30 groups for immune evaluation of the interaction between the organism and the polymer; 2% PMMA was implanted subcutaneously, 10% intramuscularly and 30% in periosteal juxtaposition and followed during five experimental days (7, 30, 90, 180 and 360 days after implantation-DAI). Pro- and anti-inflammatory cytokines (IL-2, IL-4, IL-6, IFN-gamma, TNF, IL-17A, IL-10 and TGF-beta) were quantified in all experimental days. There was no statistical difference between the groups analyzed considering the evaluated parameters. Therefore, at all implanted depths, PMMA behaved inertly in a murine model.No Level Assigned This journal requires that authors assign a level of evidence to each submission to which Evidence-Based Medicine rankings are applicable.

Profiling UK injectable aesthetic practitioners: A national cohort analysis

INTRODUCTION

The United Kingdom (UK) injectables market has been growing rapidly with a lack of robust regulation and to date, no information regarding the profile of practitioners has been published.

AIM

We aim to provide a descriptive and qualitative analysis of the advertised practitioners in the United Kingdom.

METHODS

We performed a systematic search using the internet search engine Google to perform a qualitative descriptive analysis of aesthetic practitioners in the UK. For each contiguous country in the UK: England, Scotland, and Wales, five searches were performed. The list of practitioners was then cross-referenced with professional regulatory bodies, with extraction of registration number, date of registration and presence or absence from the Specialist Register or General Practitioner Register.

RESULTS

3000 websites were visited and evaluated. 1224 independent clinics with 4405 practitioners were identified. 738 were identified as those in business support functions and the remaining 3667 practitioners were undertaking injectable practice. The profile of professions were doctors 32%, nurses 13%, dentists 24% and dental nurses 8%. Of the 1163 doctors identified 481 were on the specialist register (41%) and 219 were on the GP register (19%). 27 specialties were represented in this cohort analysis. Plastic Surgery formed the majority of those who were on the specialist register at 37%, followed by Dermatology at 18%.

CONCLUSION

This paper is the first to describe the range of practitioners, their professional backgrounds and experience who perform non-surgical aesthetic interventions. The range of backgrounds may have an impact on the potential risks to patients and will be an important consideration in proposed legislation to introduce licensing to the industry.

Therapeutic potential of adipose tissue derivatives in skin photoaging

Photoaging, the primary cause of exogenous skin aging and predominantly caused by ultraviolet radiation, is an essential type of skin aging characterized by chronic skin inflammation. Recent studies have shown that oxidative stress, inflammation, skin barrier homeostasis, collagen denaturation and pigmentation are the main contributors to it. As a composite tissue rich in matrix and vascular components, adipose tissue derivatives have been recently gaining attention as potential therapeutic agents for various human diseases with fat-processing technology upgrades. This review analyzes both 'minimally treated' and 'nonminimally treated' fat derivatives to give an overview of the preclinical and clinical relevance of adipose tissue derivatives for antiphotoaging application, highlighting their good clinical prospects as well as discussing their safety and potential risks.

Complications of toxins and fillers in facial aesthetics

Dermal filler and botulinum toxin injections are among the most performed non-invasive procedures for rejuvenation and contouring, internationally. Although most dermal fillers and approved botulinum toxins are well tolerated with a high safety profile, adverse events and/or complications can happen. Injection-related sequelae and side effects are usually rare, mild, transient, and self-limiting in nature. However, devastating and life-changing complications, such as intravascular occlusion, skin necrosis, permanent visual impairment, and stroke, have been reported. Risk reduction measures include an in-depth knowledge of anatomy, physiology, and pharmacology, correct patient selection, correct identification of clinical indications, and, fundamentally, the importance of appropriate skill and training. In this paper, some of the complications are discussed and advice on how to minimise adverse events and complications from these injectables is provided.

Hyaluronic acid-based fillers in patients with autoimmune inflammatory diseases

The use of hyaluronic acid (HA)-based aesthetic therapies is growing steadily, and according to the International Society of Aesthetic Plastic Surgery, more than 4.3 million aesthetic procedures using HA were performed in 2019, an increase of 15.7% than 2018. More people are offering these types of services, often without proper training or qualifications. Therefore, there is an increasing number of reports in the literature relating to possible adverse events, with subsequent therapeutic problems and more or less serious consequences for patients. The aim of this research is to carry out a review of the literature in order to evaluate the impact of hyaluronic acid-based fillers in patients with autoimmune inflammatory diseases, in particular scleroderma and Systemic Lupus Erythematosus (SLE). Although HA plays a central role in the inflammatory process, the use of HA-based fillers in patients with autoimmune inflammatory diseases is still controversial. HA, in fact, in inflamed tissues helps to propagate the inflammatory response and, injected in the form of a dermal filler, could potentially promote reactivation of the underlying disease. For this reason, many specialists do not perform HA-based aesthetic treatments in patients with scleroderma or SLE. However, recent scientific evidence suggests that the use of HA-based fillers in patients with scleroderma can lead to improvement of skin lesions, with satisfactory results. In the literature, there are no clinical studies that contraindicate the administration of HA-based dermal fillers in patients with inflammatory disease.

Complications of fillers in the lips and perioral area: Prevention, assessment, and management focusing on ultrasound guidance

An ever-increasing interest in perioral rejuvenation with dermal fillers reflects the esthetic importance of this region. However, filler injections in the lips and perioral area have been associated with various complications. Such complications are classified according to severity (mild, moderate, severe) or by the time of onset: immediate (within 24 h after injection), early (24 h to 4 weeks post-procedure), and late or delayed (>4 weeks after injection). While most complications are mild and manageable, vascular compromise, infections, and the development of delayed-onset nodules may significantly undermine the ultimate esthetic outcome and cause substantial morbidity. These more serious complications often require more invasive treatment modalities. This article details the prevention and management of such adverse events and discusses safe filler injection principles, including safety recommendations for the lips. Lastly, we highlight the use of ultrasound guidance in complication prevention (vascular mapping, filler identification, location, and extent), assessment (identification of intravascular embolus or external vascular compression by the filler implant), and management (real-time imaging of hyaluronidase or other drug injection in the affected area). Esthetic practitioners should be versed in injection anatomy, and the prevention, recognition, and management of filler complications in the perioral area.

Skin Cell and Tissue Responses to Cross-Linked Hyaluronic Acid in Low-Grade Inflammatory Conditions

Hyaluronic acid (HA), used in a variety of medical applications, is associated in rare instances to long-term adverse effects. Although the aetiology of these events is unknown, a number of hypotheses have been proposed, including low molecular weight of HA (LMW-HA) in the filler products. We hypothesized that cross-linked HA and its degradation products, in a low-grade inflammatory microenvironment, could impact immune responses that could affect cell behaviours in the dermis. Using two different cross-linking technologies VYC-15L and HYC-24L+, and their hyaluronidase-induced degradation products, we observed for nondegraded HA, VYC-15L and HYC-24L+, a moderate and transient increase in IL-1β, TNF-α in M1 macrophages under low-grade inflammatory conditions. Endothelial cells and fibroblasts were preconditioned using inflammatory medium produced by M1 macrophages. 24 h after LMW-HA fragments and HA stimulation, no cytokine was released in these preconditioned cells. To further characterize HA responses, we used a novel in vivo murine model exhibiting a systemic low-grade inflammatory phenotype. The intradermal injection of VYC-15L and its degradation products induced an inflammation and cell infiltration into the skin that was more pronounced than those by HYC-24L+. This acute cutaneous inflammation was likely due to mechanical effects due to filler injection and tissue integration rather than its biological effects on inflammation. VYC-15L and its degradation product potentiated microvascular response to acetylcholine in the presence of a low-grade inflammation. The different responses with 2D cell models and mouse model using the two tested cross-linking HA technologies showed the importance to use integrative complex model to better understand the effects of HA products according to inflammatory state.

TFOS Lifestyle: Impact of cosmetics on the ocular surface

In this report the use of eye cosmetic products and procedures and how this represents a lifestyle challenge that may exacerbate or promote the development of ocular surface and adnexal disease is discussed. Multiple aspects of eye cosmetics are addressed, including their history and market value, psychological and social impacts, possible problems associated with cosmetic ingredients, products, and procedures, and regulations for eye cosmetic use. In addition, a systematic review that critically appraises randomized controlled trial evidence concerning the ocular effects of eyelash growth products is included. The findings of this systematic review highlight the evidence gaps and indicate future directions for research to focus on ocular surface outcomes associated with eyelash growth products.

Delayed inflammatory reaction to hyaluronic acid lip filler after the Pfizer-BioNTech COVID-19 vaccine: A case report

Hypersensitivity reactions can be a side effect to any vaccine, but they are usually rare. The COVID-19 vaccination may cause hypersensitivity, and several cases of delayed hypersensitivity (DH) to hyaluronic acid (HA) dermal filler have been documented. The current report presents a case of a 36-year-old female patient with DH to HA dermal filler after receiving the Pfizer-BioNTech COVID-19 vaccine. Symptoms, including dryness, swelling, and a painless nodule, appeared after the first and second doses of the vaccine. The patient was treated with intralesional hyaluronidase and triamcinolone in the outpatient clinic. Although HA is relatively safe and routinely used in aesthetic medicine, DH reactions must be considered. Therefore, an appropriate patient history should be obtained, and physicians should provide counselling on the potential reactions to avoid these adverse effects.

Awareness and Knowledge of the Adverse Effects of Dermal Fillers Among the Saudi Population: A Cross-Sectional Study

Introduction Dermal filling for aesthetics and facial rejuvenation is one of the most common aesthetic procedures, with hyaluronic acid (HA) being the most commonly used filler due to its high safety profile. Nevertheless, adverse effects have been reported that people should be aware of before the procedure. This study aims to assess Saudi Arabians' awareness of dermal fillers, their side effects, and information sources. Methods This cross-sectional study used an online questionnaire to determine participants' level of knowledge, from January 2, 2022, to February 19, 2023. Statistical analysis and ordinal logistic regression were used to assess the respondents' knowledge of dermal fillers and other parameters. Results Of the 1,208 respondents, 290 reported using fillers, and 44% reported that complications were mentioned to them before the procedure. The results also showed that the primary source of information was social media (44.8%), followed by the Internet, physicians, and books. Respondents to whom physicians explained complications reported bruising, bluish discoloration at the injection site, redness, swelling, and accumulation of body cells under the skin, as discussed with them. Bruising and bluish discoloration were the significantly reported complications in people who received fillers, whereas lumps, epistaxis, ulceration/loss of skin, and swelling/accumulation were reported in those who did not receive fillers. Conclusion Although some adverse effects may occur with HA, its enormous advantages led to its use in facial rejuvenation. With social media as a major source of information, many respondents reported unlikely adverse effects as common ones, suggesting that information sources need to be corrected by physicians to raise awareness of the adverse effects of cosmetic procedures and enhance informed decision-making by patients.

Side effects after hyaluronic acid facial injection in adults during COVID-19 pandemic

BACKGROUND

Different causes may be responsible for delayed inflammatory reactions after hyaluronic acid injections, among them several mechanisms of SARS-CoV-2.

AIMS

The study's objective was to assess the percentage of adverse reactions after hyaluronic acid injections in a cohort of adult patients with a test for SARS-CoV-2 or vaccinated during the COVID-19 pandemic.

PATIENTS/METHODS

An observational, retrospective, comparative, multi-center, non-interventional in a real-life setting study was carried out with patients treated with facial injections of hyaluronic acid from May to September 2021, with a test to discard SARS-COV 2 or that had been vaccinated.

RESULTS

Sixty-three patients were included. Seven (11.1%) were vaccinated patients without a test for SaRS-CoV-2 and 56 (88.9%) with antigenic or PCR screening tests (18 [32.1%] negative and 39 [69.6%] positives for COVID-19). The mean age was 51.3 (SD 12.71; range 23-70), and 57 (90.5%) were female. Twenty-three patients (36.5%) had a history of adverse events with hyaluronic acid injections. During the study, 15 adverse events were reported; 11 patients (73.3%) had a history (p = 0.0018); two patients (13.3%) had been vaccinated; 13 (86.7%) had performed a SARS-CoV2 test (six [46.2%] negatives, and seven [53.8%] with a positive result; p = 0.5969). All adverse study events were resolved, and none had sequelae.

CONCLUSION

Adverse events after hyaluronic acid facial injections were higher among patients with a history but not among those diagnosed with COVID-19. The new scenario related to COVID-19 infections or vaccinations would require readapting criteria for applying hyaluronic acid injections.

Adverse Events Reported From Hyaluronic Acid Dermal Filler Injections to the Facial Region: A Systematic Review and Meta-Analysis

Dermal filler injections are one of the most popular cosmetic procedures in the United States. Of the many options available, hyaluronic acid (HA) dermal fillers like Juvederm or Restylane are often used. Despite their use and popularity, adverse events are known to occur from these procedures. Although most outcomes may be mild and resolve over time, rare instances of severe complications cannot be ignored, as these effects may be irreversible. Healthcare practitioners and patients must be aware of these risks, as these cosmetic procedures can affect the patient's quality of life. The aim of this study was to evaluate the incidence of adverse events (AEs) reported from the use of hyaluronic acid dermal fillers in the facial region. A systemized search of randomized controlled trials was conducted using Cochrane Central, Embase, Medical Literature Analysis and Retrieval System Online (MEDLINE), and the Web of Science databases. After screening for eligibility and conducting a critical appraisal of the articles, 19 studies were retained for the final review. The meta-analysis results included different side effects by facial location, i.e., nasolabial fold (NLF) vs. other (midface, perioral line, and lip region). The midface includes the anteromedial cheek region, the zygomaticomalar region, and the submalar region. The adverse events were swelling, pain, erythema, bruising, lumps and bumps, firmness, tenderness, itching, and skin discoloration. A significant difference was found in the proportion of individuals experiencing swelling, lumps or bumps, and firmness at the nasolabial fold site versus the midface, perioral line, and lip region. There was no significant difference in the proportion of individuals experiencing pain, erythema, bruising, tenderness, itching, or skin discoloration at the nasolabial fold site versus the other sites. The study highlights the prevalence of common AEs that can result from HA dermal fillers like Juvederm or Restylane, thus emphasizing the importance of healthcare professionals explaining the risk and benefits to patients.

Early warm compress treatment can promote recanalization of vascular embolisms and reduce tissue necrosis after polymethyl methacrylate injection

Injection of fillers for soft tissue augmentation can lead to a variety of complications, among which vascular occlusion caused by intravascular injection of filler will induce severe or permanent damage. The treatment strategies for intravascular embolization caused by injection include warm compress application, but the exact beneficial effects of this therapy have not been confirmed. The purpose of this study is to construct an intravascular injection embolism model and observe the effectiveness of warm and cold compress through a randomized, controlled trial. Thirty rabbit's sixty ears were randomly divided into warm compress group, cold compress group, and control group. Polymethyl methacrylate (PMMA) was slowly injected into the central ear artery (CEA) to cause vascular embolism. Warm compress and cold compress treatment were performed respectively. The vascular recanalization and other related indexes were observed at 30 min, 1 day, and 7 days after injection, and the tissue necrosis was analyzed at 7 days. In the early stage of vascular embolization, warm compress can immediately promote vascular dilatation, blood circulation and partial blood flow recovery. One day after intravascular injection, warm compress can reduce intravascular embolization and reduce the incidence of tissue necrosis. At 7 days after intravascular injection, the vessels in the cold compress and control groups were still embolized while the percentage of recanalization in the warm compress group was 47.4% (P < 0.000). Early-stage warm compress after intravascular PMMA injection is conducive to recanalization of vascular embolization and reducing tissue necrosis.

Standards for aseptic techniques in medical aesthetic practices in the Benelux: Consensus recommendations

INTRODUCTION

While the demand for aesthetic procedures is rising, complications are rising alongside. Infection is a frequent complication, there is therefore an increased need for strict aseptic technique, particularly in procedures breaching the skin. The level of training of practitioners carrying out these procedures varies and there are no comprehensive guidelines on aseptic aesthetic practice in the Benelux region.

OBJECTIVE

Developing a step-by-step procedure for achieving and maintaining a high standard of aseptic conditions in a standard aesthetic practice in the Benelux region.

METHODS

A consensus group of 10 aesthetic medical practitioners (dermatologists, plastic surgeons, and cosmetic physicians) representing the Benelux region convened to discuss best practice for aseptic techniques in medical aesthetics. Step-by-step procedures were recommended to achieve optimal aseptic practice in private facilities and define important considerations for reducing infection risk. Recommendations were based on current evidence and extensive clinical experience.

RESULTS

Recommendations were made to achieve and maintain a high standard of asepsis and infection control. Guidance included maintaining high standard aseptic conditions of the injecting room, the injecting area on the patient, the injection procedure, the materials, and procedures commonly used to achieve aseptic conditions.

CONCLUSIONS

This expert consensus summary publication recommends aseptic procedures, setting a standard with the goal of minimizing rates of complications in aesthetic clinical practice in the Benelux region.

Analysis of Risk Factors and Protective Strategies for Tube Blockage in Patients with Drug-Induced Liver Failure Based on Artificial Liver Therapy

Objective

To analyse the influencing factors of tube blockage during the treatment of artificial liver in patients with drug-induced liver failure and explore effective patient protection strategies.

Methods

In this study, 49 patients with pharmacological (antituberculosis drugs, antibiotics, proprietary Chinese medicine, gastric drugs, and antihyperthyroid drugs) liver failure admitted to our hospital from June 2015 to December 2021 were selected for prospective analysis. Clinical indicators and general data of all patients were collected and collated, risk factors leading to the obstruction of artificial liver treatment were analysed, and corresponding protective measures were proposed.

Results

The incidence of tube blockage was 5.32% (10 times) in 49 patients with pharmacological liver failure treated 188 times with artificial liver therapy. The incidence of tube blockage was significantly higher in patients in the PDF mode than in those in the PP and PE modes (P < 0.05), and there were differences in the location of blocked tubes between the treatment modes. Blocked tubes occurred more often in the venous cauldron of the circuit in the PDF mode and in the plasma separator of the circuit in the PP mode. The incidence of tube blockage was significantly lower in patients with no more than 3 treatments than in those with 3 to 5 treatments and those with more than 5 treatments (p < 0.05). The incidence of catheter blockage was higher in patients with PTA values ≤20% than in those with PTA values between 20% and 30%, and higher than in those with PTA values above 30% (P < 0.05).

Conclusion

The risk factors of tube plugging in patients with liver failure treated with artificial liver include different treatment modes, different treatment times, and different PTA values. The PDF mode has a higher rate of tube plugging than PE or PP treatment modes. The more the number of treatment times and the lower the PTA value of patients, the more tube plugging is likely to occur.

Efficacy and Safety of Polycaprolactone in Treating Nasolabial Folds: A Prospective, Multicenter, and Randomized Controlled Trial

Nasolabial folds (NLFs) are the most pronounced sign of facial aging. This study explored the efficacy and safety of polycaprolactone gel in treating Chinese patients with moderate-to-severe NLFs. Patients with moderate-to-severe NLF who wished to be treated by dermal fillers were recruited from three centers between July 2017 and September 2019. The randomizing ratio was 1:1 in the polycaprolactone group (polycaprolactone injection) or control group (sodium hyaluronate gel injection). The primary endpoint was the effectiveness rate of Wrinkle Severity Rating Score (WSRS) scores at 12 months after injection. The full-analysis set (FAS) and safety sets had 80 patients in the polycaprolactone group and control group, respectively. In the FAS, the effectiveness rate at 12 months in the polycaprolactone group was 88.8% compared with 23.8% in controls (P < 0.001). The improvement in WSRS sustained during 12 months in the polycaprolactone group, while gradually vanished in the control group since 3 months after surgery. The global aesthetic improvement scale (GAIS) by investigator assessments was improved, much improved, or very much improved in all patients during follow-up, while the proportion of patients with a "no change" assessment gradually increased during follow-up after 6 months in the control group. The rates of injection-related adverse event (AE) and serve injection-related AE were 8.8 versus 11.3% and 0 versus 1.3% in the polycaprolactone group and control groups, respectively. Polycaprolactone gel injection is effective and safe to treat moderate-to-severe NLFs in Chinese patients.

NOT SO "HAPPY BUMP": A complication due to hyaluronic acid

INTRODUCTION

The use of hyaluronic acid (HA) as a dermal filler is considered safe. However, as new brands come to the market, reports of adverse events are becoming more and more common.

OBJECTIVE

To describe a particular type of adverse effect that, unlike the erythematous, indurated, and painful nodules described in the literature as "angry red bumps," is characterized by noninflammatory, stony-like nodules that appear in sites previously treated with HA.

METHODS

The report of four patients who presented this complication, and the occurrence of two HA syringes from the same batch that had hardened the product inside at the time of filling.

CONCLUSION

The authors propose the nomenclature "happy bump" to group adverse reactions to HA that translate into noninflammatory nodules, with a stony consistency, appearing up to 4 weeks (recent) or after one month (late) in sites previously treated with AH.

COVID-19 vaccines and filler reactions: Should it be considered as a concern?

BACKGROUND

Any implant or external material used in the body tissues can potentially be followed by autoimmune or inflammatory reactions. With the global vaccination program against COVID-19, the reports of tissue filler reactions would be increasingly demonstrated.

AIM

To summarize the data regarding COVID vaccination and filler reactions.

METHOD

We reviewed the existing data in this regard through searching on PubMed, Google Scholar and Scopus. All of the relevant papers published until March 2022, which we could access to their fulltexts were included.

RESULTS

Here, we summarized the data regarding COVID-19 vaccination and filler reactions and discussed its etiopathogenesis, management, and importance.

CONCLUSION

Although the end of pandemic was announced, the necessity of continuing COVI-D19 vaccination in future mandates gathering data regarding safety of vaccines.

Noninvasive Correction of the Aging Forehead

Aging of the face is a continuous and dynamic process that occurs due to changes in layers including skin, muscle, fat, and bone. There is an increasing patient preference toward nonsurgical techniques and procedures that require minimal downtime in all aspects of cosmetic surgery. The mainstay of treatment involves the administration of injectable fillers for temple volumization, eyebrow reshaping and forehead contouring, and neuromodulation to reduce the appearance of dynamic rhytids. Surgical and nonsurgical procedures can be used in combination in order to maximize periorbital rejuvenation. This article focuses on nonsurgical rejuvenation of the brow and periorbital complex.

Current Practices in Hyaluronic Acid Dermal Filler Treatment in Asia Pacific and Practical Approaches to Achieving Safe and Natural-Looking Results

Complications such as delayed inflammatory reactions (DIRs) and unnatural outcomes can sometimes arise from hyaluronic acid (HA) dermal filler treatments and can be challenging to address. Given the popularity of HA dermal fillers for aesthetic procedures, there is a need for preventive strategies to minimize these complications. Two hundred practitioners from 10 regions in Asia Pacific who administer HA fillers completed a survey on prevention of DIRs and unnatural outcomes. Thirteen global experts convened to evaluate the current practices and propose practical approaches for safe and appropriate use of HA dermal fillers. From the survey, the top three measures used to reduce the risk of DIRs included choosing an appropriate HA filler, aseptic technique, and patient selection. Key strategies employed to achieve natural-looking outcomes were treatment customization, understanding the rheological properties and behavior of different HA fillers, and being conservative in treatment approach. The panel developed a concise reference guide aimed at minimizing the risk of DIRs while achieving natural aesthetic outcomes. Five practical considerations were recommended: patient assessment and individualization of treatment plan, choice of an appropriate HA filler, adequate knowledge of facial anatomy, strict adherence to aseptic methods, and proper injection technique. The panel highlighted the need for education efforts to increase awareness of differential immunogenicity between HA fillers and to improve understanding on the importance of preserving aesthetic individuality for optimal results. These practical insights from the global experts support practitioners in optimizing safety and quality of aesthetic treatment with HA fillers.

Expert recommendations on the assessment and management of complications due to hyaluronic acid soft tissue filler injections in Asians

BACKGROUND

The use of hyaluronic acid (HA) fillers for medical aesthetic purposes is increasing worldwide. Nonetheless, adverse events do occur because of patient-specific issues, injection technique, or product factors. It would be mandatory to consider cultural and anatomical features of Asians in preventing and managing the complications of HA injections.

METHODS

Literature search of studies looking at current evidence and guidelines on the management of complications following HA filler injections in Asian patients was conducted. This was followed by an expert group discussion that was convened to reach consensus recommendations on the best clinical practices.

RESULTS

The expert panel provided specific recommendations focusing on the safe use of soft tissue fillers in Asian patients, including early identification of adverse events and how to prevent and comprehensively manage these outcomes.

CONCLUSIONS

Here, we provide consensus statements of Asian experts in dermatology, plastic surgery, ophthalmology, and aesthetic medicine mainly focusing on AEs with higher risk for Asians and can be used to guide physicians in treating Asian population.

Delayed adverse reaction to a natural dermal filler mimicking salivary gland neoplasia

BACKGROUND

Cosmetic dermal fillers are a sought-after procedure globally. However, despite the safety claims of filler materials by the manufacturers, adverse reactions still occur.

CASE PRESENTATION

This case report is of a 66-year-old female who presented with a late-onset complication of a hyaluronic acid dermal filler that clinically mimicked a salivary gland neoplasm. The patient presented with firm peri-oral swellings of short duration that clinically mimicked a pleomorphic adenoma and mucoepidermoid carcinoma. The diagnosis was that of a foreign-body granulomatous response to dermal fillers. Although other mimics of a similar nature are reported a knowledgeable clinician, careful choice of filler material, knowledge of the product, thorough pre-procedural history taking and post-procedural patient follow-up can drastically minimize a possible misdiagnosis. The reaction was treated with a combination of hyaluronidase, betamethasone and 5-flurouracil intra-lesional injections monthly for 11 consecutive months, with total clinical resolution.

CONCLUSIONS

Patient education of the procedure, product name and the possibility of an adverse reaction occurring, even years later or at a site distant to the initial site of placement, is vital. Further, we review the recent reported adverse association of the new mRNA COVID-19 vaccines and dermal filler placement.

Injection Guidelines for Treating Midface Volume Deficiency With Hyaluronic Acid Fillers: The ATP Approach (Anatomy, Techniques, Products)

Midface rejuvenation is among the most valuable indications of hyaluronic acid dermal fillers, because malar projection and full upper cheeks significantly contribute to a youthful appearance. Hyaluronic acid fillers have evolved over the past 2 decades to meet specific clinical needs such as strong projection capacity and adaptability to facial dynamism. As a result, they now represent the treatment of choice for midface rejuvenation throughout age ranges by offering the potential for noninvasive treatment, immediate results, and minimal downtime. Because the 5-layered structure of the midface plays a central role in the human face, injecting the midface area may also indirectly improve other aesthetic concerns such as infraorbital hollowing and nasolabial folds. Nonetheless, midface rejuvenation requires a tailored treatment approach and a thorough knowledge of anatomy to minimize procedural risks and achieve natural-looking results. This article provides an extensive anatomical description of the midface and of the usual course and depth of vascular structures circulating nearby to delineate a treatment area and minimize procedural risks. Furthermore, considering the differential mobility and mechanical constraints of each layer of the midface, a multilayer treatment algorithm is proposed for adapting the treatment strategy to patient specificities (including age, gender, skin type, and morphology). Emphasis is also placed on desirable filler properties to create deep structural support on the one hand and accompany facial movement on the other hand.

Dermal Filler Injections in Patients With Autoimmune and Inflammatory Rheumatic Diseases-The Patients' Perspective

BACKGROUND

Injecting dermal fillers in patients with autoimmune inflammatory rheumatic diseases (AIIRDs) is controversial.

OBJECTIVE

To evaluate the attitudes of patients with AIIRDs regarding the use of dermal fillers and the side effects of those who underwent them.

METHODS

Patients with AIIRDs who attended a rheumatology outpatient clinic between 2016 and 2018 filled in a questionnaire about their attitudes toward dermal filler injections. The questionnaire evaluated information received from professionals and the factors that influenced their decision of whether or not to undergo the procedures.

RESULTS

Overall, 194 patients with AIIRDs (mean age 56.5 ± 14.0, 99% women) responded. Forty-two of them had previously undergone the injections and intended to repeat them (Group A), 37 had not received filler injections but intended to do so (Group B), and 114 who had never undergone them did not intend to undergo them. The major motivation for undergoing filler injections was social. Patients treated with dermal fillers refrained from informing their rheumatologist about their injections. They were, however, highly satisfied with the procedure and reported negligible side effects.

CONCLUSION

The use of dermal fillers was apparently safe and well received by patients with AIIRDs. Physicians' recommendations to refrain from injecting them with dermal fillers should be reconsidered and evaluated in clinical studies.

A comprehensive, modular, and highly individualizable method has been developed: the Lip Omnicomprehensive Volume Enhancement (LOVE) approach. The present study assessed the safety and effectiveness of LOVE across different patient age groups.

Complications of Nonpermanent Facial Fillers: A Systematic Review

Background:

A variety of complications after injection of nonpermanent fillers for facial rejuvenation have been reported so far. However, to date, the overall complication rate is still a matter of debate. The aim of this study was to perform a systematic review of literature to assess the type and severity of associated complications following injections in different anatomical regions of the face.

Methods:

The entire PubMed/Medline database was screened to identify case reports and clinical studies describing complications that have occurred after injection of nonpermanent fillers in the face. These complications have been reviewed and analyzed according to their occurrence in different anatomical regions of the face.

Results:

Forty-six articles including a total of 164 patients reported on a total of 436 complications during the time period between January 2003 and February 2020. The majority of the complications were reported after injections to the nose and the nasolabial fold (n = 230), the forehead and the eyebrows (n = 53), and the glabellar region (n = 36). Out of 436 complications, 163 have been classified as severe or permanent including skin necrosis (n = 46), loss of vision (n = 35), or encephalitis (n = 1), whereas 273 complications were classified as mild or transient, such as local edema (n = 74), skin erythema (n = 69), and filler migration (n = 2). The most severe complications were observed in treatments of nose, glabella, and forehead.

Conclusions:

Nonpermanent facial fillers are associated with rare but potentially severe complications. Severity and impact of complications depend on the anatomical region of the face and eventually require profound knowledge of facial anatomy.

Laser Doppler Imaging for Treating Vascular Complications from Procedures Involving Dermal Fillers: Case Series and Literature Review

Vascular occlusion is a rare but severe complication of dermal filler injections. Early treatment of this complication produces better outcomes. Current diagnostic methods for vascular occlusion in the skin are subjective and imprecise; these include capillary refill time, skin color, and reports of pain. This study aimed to assess the use of laser Doppler imaging (LDI) in the evaluation and treatment of vascular complications caused by dermal filler injections. This retrospective study used laser Doppler imaging (LDI) in 13 patients who developed vascular occlusion after facial dermal filler injections, with subsequent follow-up. The precise areas of perfusion observed on LDI were compared with the findings of clinical and photographic evaluation. The results showed that LDI accurately identified areas of vascular occlusion and improved treatment precision among these thirteen patients. The procedure was more precise than visual inspection or photographic evidence. Satisfactory outcomes were achieved for all patients, and no procedure-related complications were reported. Collectively, LDI provides fast, noninvasive, and accurate delineation of areas of vascular occlusion caused by complications of dermal filler injections and avoids several subjective shortcomings of visual and photographic evaluations. Thus, LDI effectively tracks treatment outcomes. However, large-scale studies are required to confirm the present findings.

Recognizing, Managing, and Guiding the Patient Through Complications in Facial Plastic Surgery

Complications in facial plastic surgery can occur in both surgical and nonsurgical procedures. Many complications can be prevented through thorough preprocedural evaluation, patient counseling, and close postoperative monitoring. Despite the best efforts complications will happen and identifying them early is critical to prevent long-term sequelae. It is important to know how to both manage the complication and guide the patient through the recovery process.

Hyaluronic acid soft tissue filler delayed inflammatory reaction following COVID-19 vaccination - A case report

Background

The use of hyaluronic acid soft tissue fillers in aesthetic medicine exploded in recent years for many reasons, including being relatively safe. Incidence of delayed inflammatory reactions (DIRs) to hyaluronic acid soft tissue fillers range between 0.3% and 4.25%. These reactions are mediated by T‐lymphocytes and can be triggered by flu‐like illnesses, including SARS‐CoV‐2 infection. Vaccination may also induce hypersensitivity.

Aim

In this case report, we present two cases of delayed reaction after hyaluronic acid soft tissue filler treatment of the tear trough area and following mRNA vaccination against SARS‐Cov‐2, also known as COVID‐19, months later.

Patients

A 39‐year old female who previously had her tear trough area treated with hyaluronic acid soft tissue filler developed swelling days after getting the mRNA Pfizer‐BioNTech COVID‐19 vaccine. Another patient, a 61‐year‐olf female, developed intermittent facial swelling in areas previously treated with hyaluronic acid soft tissue fillers days after receiving her first dose of the mRNA Pfizer‐BioNTech COVID‐19 vaccine.

Results

As demonstrated in our case report, vaccination against COVID‐19 may induce DIRs in patients who previously had hyaluronic soft tissue fillers.

Conclusion

Delayed inflammatory reactions to hyaluronic acid soft tissue fillers are uncommon and usually self‐limited, with frequent spontaneous resolution. However, considering the ongoing pandemic and the worldwide demand for vaccines against COVID‐19, the aesthetic providers should be conscious of the risks posed by the interaction of such vaccines in patients who previously had or seeking hyaluronic acid soft tissue filler injections.

Delayed-onset Nodules (DONs) and Considering their Treatment following use of Hyaluronic Acid (HA) Fillers

Delayed-onset nodules (DONs) represent a poorly understood and generally neglected group of complications. It is not a diagnosis. The underlying pathologies and their incidences are largely unknown due to the lack of specificity in clinical signs and the challenges in accessing diagnostic tests, cost implications, or reluctance from patients to undergo them. A lack of presumptive clinical diagnosis, coupled with management ranging from "scatter-gun" polypharmacy to clinical inertia, is believed to result in chronicity and increased morbidity. This paper provides guidance on the identification and understanding of the underlying pathologies and encourages the increased utilization of a medical model of care. The more routine adoption of histopathology, inflammatory markers, and ultrasound will permit a more targeted management and a greater understanding of the incidences and evolution of the pathologies.

Recommendations for the use of corrective makeup after dermatological procedures

Introduction

The number of dermatological or cosmetic procedures carried out has continuously increased over the last decades. Almost all may cause transient local skin reactions such as erythema, blistering, crusts, scaling, hypo‐ or hyperpigmentation, or hemorrhagic lesions. One issue of dermatological procedures is the downtime, during which patients need to hide their skin, due to these local reactions.

Aim

To provide dermatologists with easy‐to‐follow recommendations for the right timing of use of corrective makeup for patients who have undergone or who plan to undergo dermatological procedures, according to the invasiveness of the dermatological procedure chosen.

Methodology

A group of experts in dermatological procedures met in 2019 and at the beginning of 2020 to discuss the different procedures, their local reactions and downtime, and the opportunities to use specific corrective makeup in order to hide these transient reactions.

Results

As a result of the discussions, the experts proposed a tabulated algorithm of use based on a classification of the different dermatological procedures according to their invasiveness and recommended timing of the first post‐procedure corrective makeup application.

Conclusion

Corrective makeup may be considered as a complement to certain dermatological procedures in order to minimize downtime. However, its use is conditioned by the correct understanding of skin barrier alteration and recovery time. The proposed algorithm of use of corrective makeup after procedures may help the practitioner to indicate his patient the right moment for applying corrective makeup in order to avoid local tolerance issues and post‐procedure complications.

A case of delayed inflammatory filler reaction following vaccination with succesful response to colchicine

Delayed inflammatory reactions (DIRs) associated with hyaluronic acid injections are not rare and can be seen in up to 4.25% of patients. Although the exact mechanism is not clear, several triggering factors, including infections, trauma, and dental procedures, were reported in the literature. A 43-year-old female patient treated with HA fillers developed an inflammatory reaction following vaccination in all areas of injection, including temples, lips, and lower eyelids. Systemic steroid and ciprofloxacin were used as a first-line treatment without response. Colchicine 1 mg/day along with hyaluronidase in lower eyelids improved all lesions successfully.

Complications and Adverse Effects of Periocular Aesthetic Treatments

The popularity and variety of temporary and permanent periocular aesthetic treatments has increased over the past decade. Patients frequently present to eye clinics with ocular complications and side effects following these treatments, their severity ranging from ocular irritation from dry eyes to visual loss from vascular occlusion. A careful, thorough history is essential, as many patients may not associate aesthetic procedures with ocular complications, and some may be embarrassed to disclose this information. All ophthalmologists should understand the potential ocular sequelae of these treatments and be able to initiate treatment in sight-threatening cases. Wesummarises the current literature on ophthalmic complications of the most common periocular aesthetic treatments.
