Skin Necrosis and Vision Loss or Impairment After Facial Filler Injection

Efficacy and Safety of Neauvia Intense in Correcting Moderate-to-Severe Nasolabial Folds: A Post-Market, Prospective, Open-Label, Single-Centre Study

Purpose

 This prospective, single-center study aims to evaluate the safety and effectiveness of NEAUVIA Intense, a PEG cross-linked polymeric hydrogel, in correcting moderate-to-severe nasolabial folds (NLF) in a routine clinical setting. The study investigates the aesthetic outcomes, patient satisfaction, and adverse events associated with the injectable filler.

Patients and Methods

Seventy patients were initially enrolled, with 60 meeting study parameters. The post-market study involved a single session treatment, employing NEAUVIA Intense on each side of the NLF. Assessments utilized the Modified Fitzpatrick Wrinkle Scale (MFWS), Global Aesthetic Improvement Scale (GAIS), and Visual Analogical Scale (VAS).

Results

 The study demonstrated a statistically significant improvement in tissue depression immediately post-injection (p < 0.001), with sustained effects up to 6 months. MFWS assessments revealed that responder patients were 96.6% immediately after treatment, 76.6% one month, 48.3% after 3 months, and 28.3% at 6 months (p < 0.001). Additionally, there was a significant change in the frequency distribution of MFWS scores post-treatment (p < 0.001), with the majority of patients experiencing improvement in tissue depression. Maximum improvement was observed at 30- and 90-days post-treatment based on GAIS assessments. Patient and physician satisfaction, measured by VAS, remained stable over time, with fluctuations at 4 and 24 weeks after treatment (p < 0.001, Anova; p < 0.05, Wilcoxon). Throughout the entire follow-up duration of the patients enrolled in the study, no adverse effects related to the use of the product were observed.

Conclusion

 NEAUVIA Intense proved to be an effective solution for correcting NLF, providing significant and lasting improvements in tissue depression and aesthetic outcomes. The study underscores the necessity for continuous assessment in aesthetic medicine to align outcomes with evolving patient expectations and optimize long-term results. The findings contribute to the understanding of this specific hydrogel filler and highlight the broader context of injectable fillers in comprehensive facial aesthetic strategies.

Monocular Vision Loss After Ear Filler Injection

Ophthalmic artery occlusion caused by facial hyaluronic acid filler injection has always been a rare but devastating complication. With the pursuit of beauty, people have become more interested in ears and hyaluronic acid fillers. Herein, we report the case of a more serious rare complication of ophthalmic artery occlusion caused by ear filler injection. A 45-year-old woman developed vision loss on the left side immediately after receiving cosmetic hyaluronic acid injection in the ear, with only the visual field at the inferior temporal side remaining. She was diagnosed with central retinal artery occlusion in the left eye. After treatment with hyaluronidase injection, dexamethasone, hyperbaric oxygen, and oral alprostadil, blood flow was partially restored in the left ophthalmic artery, and her vision improved. Vascular complications after ear injections are rare. However, as the demand for ear filler injections increases, the probability of serious vascular complications is predicted to increase. The potential mechanism by which occlusion occurred involved the filler reaching the superficial temporal artery system through the superior auricular artery, thus occluding the ophthalmic artery. Having an understanding of anatomy is an important measure to avoid complications.Level of Evidence IV This journal requires that authors assign a level of evidence to each article.

Vascular complications with necrotic lesions following filler injections: Literature systematic review

INTRODUCTION

Although the related risk of vascular necrosis due to filler injection is low, the outcomes can be severe when they occur. This systematic review aims to report the occurrence and treatment of vascular necrosis due to filler injection.

MATERIALS AND METHODS

The systematic review was performed according to PRISMA guidelines.

RESULTS

The results showed the most used treatment is a combination of pharmacologic therapy and hyaluronidase application, which is efficacy when applied in the first 4 h. In addition, even though management recommendations are available in literature, proper guidelines are unavailable due to the low number of complications occurrence.

CONCLUSION

Clinical and high-quality studies on treatment and management of filler injection combination are necessary to provide scientific evidence on what to do in case of vascular complication occurrence.

Adverse Events Following COVID-19 Vaccine in Patients Previously Injected with Facial Filler: Scoping Review and Case Report

The “Vaccines and Related Biological Products Advisory Committee 17 December 2020 Meeting Briefing Document”, formulated by the FDA, reported three cases of swelling in areas previously injected with HA filler, introducing the possible relationship between a COVID-19 vaccine and adverse events in areas previously injected with HA fillers. The aim of this research is to report a case of an adverse event following a COVID-19 vaccine in a patient previously injected with facial filler. Furthermore, a scoping review on the same topic was performed. The research was carried out on the electronic databases PubMed, Cochrane Library, Web of Science, Google Scholar and Scopus. The selection process identified four articles as eligible for inclusion in the review. Nineteen patients, including the described case report, who experienced an adverse event following a COVID-19 vaccine in areas previously injected with facial filler were identified. Adverse events following a COVID-19 vaccine in patients previously injected with facial filler appear to be rare. A high BDDE cross-linking rate and/or a low-molecular-weight hyaluronic acid filler may have a higher tardive adverse event rate when triggered.

Clinical Experience with PEGylated Hyaluronic Acid Fillers: A 3-year Retrospective Study

BACKGROUND: Hyaluronic acid fillers are the most used worldwide, thanks to the high biocompatibility and safety profile of HA and it is also the only substance that can be “dissolved” due to the hyaluronidase effect. AIM: A retrospective clinical evaluation of the outcomes following PEG cross-linked HA-based filler injection was performed. METHODS: Data were collected from December 2017 to June 2020. A total of 65 patients (12 M, 53 F), age ranging 28–62 year’s old (mean age 42.3), were treated. Exclusion criteria were applied and in accord to treatment plan, were used specific site injections and fillers. Follow-up was evaluated between 6 months and 2 years. RESULTS: A total of 61 treatments using 124 vials of HA filler crosslinked with PEG were performed. CONCLUSION: In conclusion, from 2014, HA fillers having PEG as cross-linker agent have been introduced in the european market. Several papers have been published in order to evaluate the features of these fillers, although, to the best of our knowledge, this is the first clinical paper regarding their use.

Tissue Fillers for the Nasolabial Fold Area: A Systematic Review and Meta-Analysis of Randomized Clinical Trials

Abstract

Tissue fillers injections remain to be one of the most commonly performed cosmetic procedures. The aim of this meta-analysis was to systematize and present available data on the aesthetic outcomes and safety of treating the nasolabial fold area with tissue fillers. We conducted a systematic review of randomized clinical trials that report outcomes concerning treatment of nasolabial fold area with tissue fillers. We searched the MEDLINE/PubMed, ScienceDirect, EMBASE, BIOSIS, SciELO, Scopus, Cochrane Controlled Register of Trials, CNKI and Web of Science databases. Primary outcomes included aesthetic improvement measured using the Wrinkle Severity Rating Scale score and Global Aesthetic Improvement Scale. Secondary outcomes were incidence rates of complications occurring after the procedure. At baseline, the pooled mean WSRS score was 3.23 (95% CI: 3.20–3.26). One month after the procedure, the pooled WSRS score had reached 1.79 (95% CI: 1.74–1.83). After six months it was 2.02 (95% CI: 1.99–2.05) and after 12 months it was 2.46 (95% CI: 2.4–2.52). One month after the procedure, the pooled GAIS score had reached 2.21 (95% CI: 2.14–2.28). After six months, it was 2.32 (95% CI: 2.26–2.37), and after 12 months, it was 1.27 (95% CI: 1.12–1.42). Overall, the pooled incidence of all complications was 0.58 (95% CI: 0.46–0.7). Most common included lumpiness (43%), tenderness (41%), swelling (34%) and bruising (29%). Tissue fillers used for nasolabial fold area treatment allow achieving a satisfying and sustainable improvement. Most common complications include tenderness, lumpiness, swelling, and bruising.

Non-Surgical Touch-Up with Hyaluronic Acid Fillers Following Facial Reconstructive Surgery

The use of hyaluronic acid (HA) injectable fillers has become increasingly widespread in facial recontouring and rejuvenation. We report our experiences to emphasize the role of HA fillers as tools beyond aesthetic treatments in cases of post-surgical facial sequelae. HA fillers are generally used for aesthetic rejuvenation, but one potential new horizon could be their application in trauma, reconstructive, and craniofacial surgery. This study was conducted retrospectively, evaluating medical reports of patients treated at the Maxillofacial Surgery Unit, University of Campania “Luigi Vanvitelli”, Naples, for lip incompetence, trauma, oncological, reconstructive, and craniosynostosis surgery sequelae. Visual analog scale (VAS) evaluation was performed to assess patient satisfaction. No major complications (i.e., impending necrosis or visual loss) were reported. Bruising and swelling was reported for 48 h after lip injection. At the immediate VAS evaluation, 67% of the patients were “extremely satisfied” and 33% “satisfied”. In those 33%, VAS scores changed to “extremely satisfied” at 6–9 weeks and 3–6 months of VAS evaluation (contextually to improvement in tissue flexibility, elasticity, and aesthetic appearance). Results indicate that this minimally invasive approach achieves a high level of aesthetic enhancement, improving patient satisfaction. The concept of HA filler applications could be a frontier that may be applicable to other areas of reconstructive facial plastic surgery.

Surgical Lip Remodeling Following Permanent Filler Injection: A Scoping Review

ABSTRACT

Over the years, several techniques have been introduced to obtain permanent lip enhancement, such as the use of silicone lip implants or the off-label use of permanent fillers. Although some reports indicate that permanent lip filler is safe, many others describe early- and late-onset complications. The main issue with permanent lip fillers is the lack of a standard technique to correct undesirable results. The aim of this scoping review was to list and evaluate the surgical pathways described in literature to correct lip deformity resulted from the injection of permanent fillers. The methods and the inclusion criteria of this work were specified in advance and documented in a protocol, according to the PRISMA 2009 checklist. The research was carried out on electronic databases PubMed, Cochrane Library, and Scopus databases identifying articles from March 1991 to December 2020 and conducted up to December 23rd, 2020. Articles language was limited to English. The selection process identified 3 retrospective studies eligible for inclusion. 73 patients and a total of 111 lips (72 upper and 39 lower) were considered. Two early complications were identified, 1 suture dehiscence and 1 total lip mucosa necrosis. Surgical lip remodeling following permanent filler injection seems to be an effective approach although the surgical pathway needs to be customized per each patient. Complication rate seems to be coherent to lip surgery performed with reconstructive purposes. To confirm these data case-control studies with much wider cohorts are needed to reach statistical significance.

Facial Rejuvenation with Concentrated Lipograft-A 12 Month Follow-Up Study

Lipofilling is a popular technique to treat volume loss in aging patients. The isolated adipose tissue is composed of adipocytes and stromal vascular fraction cells, which include adipose-derived stem cells (ASC). We hypothesize that the patient’s wrinkle severity scale (WSS) and patient’s satisfaction on the global aesthetic improvement scale (GAIS) can be improved after using concentrated lipoaspirate. Fourteen patients (54 years ± 11.09 years) with volume loss in the midface area underwent waterjet-assisted liposuction (Human Med AG, Schwerin, Germany). Fat was centrifuged in an ACP Double Syringe (Arthrex GmbH, Munich, Germany) using Rotofix 32A centrifuge (Andreas Hettich, GmbH & Co.KG, Tuttlingen, Germany). Homogenization was performed using the double syringe and a 1.4 mm female–female luerlock connector. After a second centrifugation, patients received periorbital (PO) and nasolabial (NL) lipografting. ASC count was performed after enzymatical digestion. Vitality of cells was assessed using a resazurin assay. During long-term follow up (12 months, n = 10), we found a high patient’s satisfaction (GAIS 1+/−0.52) and a good improvement of the WSS during short- and long-term follow-up. The ASC count of processed lipoaspirate was 2.1-fold higher than of unprocessed lipoaspirate (p < 0.001). The difference of ASC in sedimented and simply centrifuged lipoaspirate was also significant (p < 0.05). Facial rejuvenation with concentrated fat graft offers good results concerning objective aesthetic outcome and patient’s satisfaction.
