Late Subcutaneous Infection Caused by Serratia marcescens Following Hyaluronic Acid Injection: A Case Report and Systemic Review.

The field of cosmetic filler injection has experienced rapid development over the past two decades, especially in facial augmentation utilizing hyaluronic acid (HA) fillers. Gram-negative bacteria are found to be the main pathogens of infective nodules after HA injection. The occurrence of cutaneous infections attributed to Serratia marcescens is exceedingly rare and predominantly noted in patients with compromised immune systems. To summarize the clinical features, diagnosis, and treatment of subcutaneous infection caused by Serratia marcescens following hyaluronic acid injection. A rare case of cutaneous Serratia marcescens infection following hyaluronic acid injection was presented. A comprehensive review of the published literature describing the management of skin infection caused by S. marcescens in immunocompetent patients was then conducted, which encompassed three case series and eight case reports published between 1999 and 2017. Data extraction included information on authors, gender, age, signs and symptoms, previous treatment, corresponding management strategies, and follow-up duration. Serratia marcescens were isolated in abscesses (n = 6, 35.29%), painful nodules (n = 2, 11.76%), ulcers (n = 6, 35.29%), and others (n = 3, 17.65%). In cases providing salvage plans (n = 11), quinolones were shown to be the most effective antibiotics for salvage, with eight full recoveries (72.73%), and trimethoprim-sulfamethoxazole was the second most useful antibiotic (18.18%). With the help of pathogen examination and drug-sensitive tests, sensitive aminoglycosides, quinolone (especially moxifloxacin), or TMP-SMX for at least 2 weeks can be considered as the first-line treatment of late subcutaneous infection caused by Serratia marcescens following hyaluronic acid injection.

An Innovative Treatment Using Calcium Hydroxyapatite for Non-Surgical Facial Rejuvenation: The Vectorial-Lift Technique

BackgroundThe facial aging process entails alterations in the volume, shape, and texture of all skin layers over time. Calcium hydroxyapatite (CaHA) is a well-established safe skin filler with unique properties to resolve some skin alterations by stimulating neocollagenesis. The vectoral-lift (V-lift) technique targets the global repositioning of facial structures by addressing distinct anatomical injection planes. It includes deep facial augmentation with Radiesse PlusTM to retain ligament restructuring and superficial subcutaneous enhancement with diluted Radiesse DuoTM. Herein, we present cases that illustrate the use of this approach.MethodsThis pilot study enrolled 36 participants (33 women and three men; ages 37–68 years) in a Brazilian clinical setting, and all patients underwent a single treatment. Photographs were taken at rest, in frontal and oblique views, before injection, and 90 days after treatment.ResultsTreatment resulted in elevation of the upper and middle face, notable improvements in the infraorbital hollow, and adjustment of the mean facial volume.ConclusionsThe V-lift technique is a three-dimensional pan-facial treatment that relies on ligament support and face vectoring to obtain a lifting effect and facial contour restoration. It encompasses deep facial augmentation involving the use of Radiesse PlusTM for restructuring and retaining ligaments and Radiesse DuoTM for superficial subcutaneous enhancement. This approach targets a global repositioning of the facial structures by addressing distinct anatomical injection planes. It achieves a repositioning of the overall facial anatomy without requiring a substantial volumetric expansion.Level of Evidence IVThis journal requires that authors assign a level of evidence to each article.

Visualization Mapping and Current Trends of Facial Contouring Procedures: A Bibliometric Analysis Based on Web of Science.

Facial contouring procedures become popular in recent years, but there has been no bibliometric analysis focused on this field. Construct visualization maps and analyze the hotspots and current trends in this field using bibliometric analysis. Publications on facial contouring procedures were extracted from the Web of Science Core Collection database from 2003 to 2022. VOSviewer, CiteSpace, and "Bibliometrix" R package were used to analyze data. Seven hundred and twenty-one publications on facial contouring procedures between 2003 and 2022 were included. The United States was the leading country both in publications (206) and citations (3941). Shanghai Jiao Tong University was the institution with the greatest contribution (35 publications with 379 citations). Hu J (17 publications) from China had the most outputs, while the most cited author was Rohrich RJ (321 citations) from the United States. The Journal of Craniofacial Surgery (135 documents) published the most research, and Plastic and Reconstructive Surgery was the most cited journal (2755 citations). The most cited article focused on virtual surgical planning in mandibular reconstruction. Keywords co-occurrence analysis identified five clusters centered on "reconstruction," "augmentation," "reduction malarplasty," "face rejuvenation," and "orthognathic surgery," separately. "Hyaluronic acid," "facial feminization," and "orthognathic surgery" might be related to trend topics. The research on facial contouring procedures is booming. In the past 2 decades, hotspots in this field included: facial defects reconstruction, facial augmentation cosmetology, facial skeletal contour plasty, and facial rejuvenation surgery. The following aspects may be trend frontiers: precision and personalization, combined treatments, transgender facial contour, and facial contour shaping with fat and hyaluronic acid.

Surface modification of PEEK implants for craniofacial reconstruction and aesthetic augmentation-fiction or reality?

Facial implantology, a crucial facet of plastic and reconstructive surgery, focuses on optimizing implant materials for facial augmentation and reconstruction. This manuscript explores the use of Polyetheretherketone (PEEK) implants in craniofacial surgery, highlighting the challenges and advancements in this field. While PEEK offers mechanical resilience, durability, and compatibility with imaging modalities, its biologically inert nature hinders integration with the host tissue, which may lead to complications. In this systematic review, our aim was to assess the current state of knowledge regarding the clinical evaluation of Polyetheretherketone (PEEK) implants in facial implantology, with a focus on craniofacial augmentation and reconstruction in human studies. Additionally, we explore and discuss surface and structural modifications that may enhance bioreactivity and reduce complications in PEEK implants. A systematic review identified 32 articles detailing the use of PEEK Patient-Specific Implants (PSIs) in 194 patients for both reconstructive and aesthetic purposes. Complications, including infections and implant failures, were reported in 18% of cases, suggesting the need for improved implant materials. The discussion delves into the limitations of PEEK, prompting the exploration of surface and structural modifications to enhance its bioreactivity. Strategies, such as hydroxyapatite coating, titanium coating, and porous structures show promise in improving osseointegration and reducing complications. However, the literature review did not reveal reports of coated or modified PEEK in facial reconstructive or aesthetic surgery. In conclusion, although PEEK implants have been successfully used in craniofacial reconstruction, their biological inertness poses challenges. Surface modifications, particularly hydroxyapatite coatings, provide opportunities to promote osseointegration. Future research should focus on prospective long-term studies, especially in craniofacial surgery, to investigate the stability of uncoated PEEK implants and the potential benefits of surface modifications in clinical applications. Patient-specific PEEK implants hold promise for achieving durable craniofacial reconstruction and augmentation.

Virtual Modeling in Gender-Affirming Facial Masculinization Surgery.

The increase in access to facial gender-affirming surgery has resulted in a rise in facial feminization surgeries for transfeminine and gender non-binary populations. However, refined execution of facial masculinization is challenged by the lack of defined measurements for facial augmentation, the lack of long-term predictability in autologous bone grafting in augmentation procedures, and the lack of precision in traditional facial augmentation procedures with generic alloplastic implants. In this work, we describe an innovation in facial masculinization surgery using modern reconstructive craniofacial surgical techniques with preoperative virtual modeling and the fabrication of three-dimensionally printed, patient-specific custom implants.

Artículo traducido] Uso de rellenos faciales en la práctica clínica: nivel de satisfacción del paciente y visión general de las complicaciones clínicas comunes

BackgroundPatient esthetic satisfaction following facial fillers is an essential topic that should be studied as the number of individuals seeking treatment increases. The face is an essential component of the human body that is frequently associated with beauty, youthfulness, and health. Individuals may seek facial augmentation with fillers for a variety of reasons, such as congenital, acquired by means of aging or disease, or current aesthetic trends. ObjectiveThe aim is to assess patient's aesthetic satisfaction and description of common clinical complications in relation to the facial filler injections. MethodA cross sectional survey using a questionnaire derived from the global aesthetic improvement scale and WHO quality of life scale, convenience sampling was used to recruit patients attending cosmetic clinics, descriptive analysis and Chi-square methods were used to analyze the data. ResultsIn the study, 500 female participants, with an average age of 28.48 years, were included. Over 90% reported improvement after filler treatment, ranging from improved to very much improved. A statistically significant correlation was observed between patient satisfaction and the number of filler treatments and the anatomical injection site. However, no statistically significant correlation was found when considering age groups. Local side effects, such as swelling and redness at the injection site, were common but generally mild and of short duration. ConclusionAlthough the satisfaction level is currently high, practitioners in the field need to pay more attention to this important outcome, since understanding the patient's motivation and expectation before proceeding with the procedure is very important and can contribute significantly in determining patient satisfaction with the result.

In Vitro Cytocompatibility Analysis and Comparison of Different Hyaluronic Acid Fillers for Minimally Invasive Esthetics.

To overcome the natural visual consequences of the physiological aging process, the use of biodegradable fillers made of hyaluronic acid or sodium carboxymethyl cellulose is increasingly popular in modern esthetic medicine. Clinicians can choose from a wide range of fillers with variable compositions and rheological properties, and therefore with different application areas and injection depths. The aim of this study was to analyze and compare the most commonly used fillers for facial augmentation regarding their in vitro biocompatibility and to find potential correlations to their rheological properties. In the present study, direct and indirect in vitro cytotoxicity analysis according to DIN EN ISO 10993-5 were performed on 39 different filler materials for facial augmentation. All fillers analyzed in this study overall showed satisfactory results in the direct and indirect cytocompatibility tests. While no material was outside the threshold values in the 2,3-bis-(2-methoxy-4-nitro-5-sulphenyl)-(2H)-tetrazolium-5-carboxanilide (XTT) cell viability and bromodeoxyuridine (BrdU) cell proliferation assays or in the live-dead staining, only 7 out of the 39 fillers reached the required values in the lactate dehydrogenase assay. All biodegradable fillers examined in this study were found to be sufficiently cytocompatible. Although the qualitative analysis of the test results showed differences between the fillers, no concrete correlation between test performance and composition or manufacturer of the fillers was found. Future efforts are required to provide clinicians with even better support in choosing the right filler for optimal outcome and patient satisfaction.

Mammoplastie d’augmentation par injection d’hydrogel de polyacrylamide : rapport d’un cas récent et revue de la littérature

Polyacrylamide hydrogel (PAAG) is a filler that has been strictly prohibited in France for many years. It first appeared on the market in 1980, used as an injectable for breast and facial augmentation, mainly in Asia and Eastern Europe. Like many other materials, it has shown unfavourable results and complications due to a foreign body reaction. It was banned in 2006, but continues to be injected illegally. With the influx of migrants, we are faced with the problem of how to manage complications, which can occur more than a decade later. We report our experience of a recent case in our department that required complete removal of the product and iterative lipofilling, with a result that remains sub-optimal, and we systematically review the literature.

HYALURONIC ACID USING THE “FERN PATTERN TECHNIQUE” TECHNIQUE - SLEEP WRINKLES TREATMENT

The skin, due to its protective role, suffers from exogenous factors (ultraviolet radiation, pollution and trauma) and endogenous factors (endocrine-metabolic diseases, alcohol and tobacco use), a sequence of functional alterations and/or structural problems that could harm its integrity, leading to dyschromia, dehydration, loss of elasticity and microvascular alterations. Wrinkles are an indicator of facial aging, with fault lines occurring in the skin, due to skin distortions resulting from facial expression or mechanical movements and compressions during sleep. Expression and sleep wrinkles differ in etiology, location and anatomical pattern. The skin during sleep undergoes compression, shear and tension forces that act on the face when we are in lateral or prone sleeping positions. Hyaluronic acid, since the 1990s, has been employed as a favorable temporary filler option for facial augmentation and for the regulation of various biological processes, such as skin repair, wound healing, tissue regeneration, reaching the prominent place regarding the treatment of wrinkles. This work aims to report a case of treatment of sleep wrinkles, in a female patient, only treated with fillers based on hyaluronic acid, with the “Fern Pattern Technique” technique with evolution of 2 years and with a single application.

Use of Hyaluronic Acid Filler in Patients with Secondary Cleft Lip Deformity.

Retrospective case note review was undertaken of all patients treated in the clinic over a two-year period. 20 patients underwent HA filler injections to the upper lip 26 times. Most were female (F:M = 3:1) and patients were aged 18-58 years. Most patients had a unilateral cleft lip +/- palate (n = 13, 65%). The most common indication was to address upper lip volume (n = 13, 65%). Other indications included vermillion notch (n = 5, 25%), cupid bow peak height asymmetry (n = 4, 20%), scar asymmetry (n = 1, 5%) and nasal sill flattening (n = 1, 5%). Small volumes of filler were used with an average of 0.34 ml (range 0.05-1.2 ml). There were no complications and one patient reported pruritis post procedure. HA filler is a safe and reliable treatment for certain aspects of asymmetry following cleft lip repair. It can be used to address volume deficiency and asymmetry, cupid bow peak height discrepancies and a vermillion notch for patients who do not want surgery. Injection of HA to the lips can be performed easily, with appropriate training, in the outpatient setting.

Silicone Facial Implants, to Fixate or Not to Fixate: A Narrative Review.

Silicone implants are one of the most widely used implants for facial augmentation, especially in the chin, mandibular angle, and malar area, utilizing different surgical approaches. Despite their various advantages, many complications have also been reported, including hematoma, infection, bone resorption, numbness, displacement, and asymmetry. This study aims to evaluate the need for facial-implant fixation and compare and contrast fixated and nonfixated facial silicone implants in different facial sites. A narrative review of the topic of facial-implant stabilization using the PubMed database inclusion criteria included articles that discussed the topic of facial implants, were published in English, and included critical information such as the location of the implant, type of stabilization, follow-up periods, and complications. A total of 11 studies were included. Of these, two were prospective clinical studies, three were case series, and the remaining six were retrospective clinical studies. The studies were published between 1995 and 2018. The sample size varied from 2 to 601 cases. Stabilization includes suturing, monocortical screws, or no stabilization. Complications were reported in most of these studies, including asymmetry, bone resorption or erosion, displacement, dissatisfaction, edema, hematoma, infection, mucosal irritation, pain, and paresthesia. The follow-up period ranged from one month to 17 years. Despite the varied settings of these studies, silicone facial implant complications were reported in both fixated and nonfixated implants, with a lack of significant differences between fixated and nonfixated facial silicone implants regarding the method of fixation.

Agarose Gel: An Overview of the Dermal Filler and a Clinical Experience With 700 Patients.

Dermal fillers currently in the market have several advantages and disadvantages over each other. Agarose gel (AG) is a unique material due to its special rheological characteristics and gel-forming capability. The authors aimed to share their clinical experience on AG for a variety of facial augmentation procedures and its long-term results. The study population consisted of 700 patients (532 females; 168 males) aged 18 to 52 years. Follow-up visits were at 1, 3, 6, 12, and 24 months after the injections. Patient satisfaction was evaluated on a scale from 0 to 10 using a survey and clinical improvement was evaluated using the Global Aesthetic Improvement Scale (GAIS) by 2 independent plastic surgeons before the injection and at 1-year follow-up. Eighty-two percent of the patients scored 1 or 2 (exceptional or great improvement) on GAIS. Eighty-five percent of the patients scored 8 or above (very satisfied). Most patients experienced at least 80% persistence of effect at 1-year follow-up. AG appears to be suitable for a variety of facial augmentation and contouring applications, as it is safe and has long-lasting favorable cosmetic efficacy.

The challenges associated with fused deposition modelling of high-density polyethylene for facial augmentation implants: a review

High-density polyethylene (HDPE) implants are widely employed in craniomaxillofacial augmentation surgery because of their unique ability to bond with tissues for bone repair and functional recovery of the facial areas which are affected by acquired or congenital facial deformities. The direct manufacturing of HDPE implants as patient-specific implants through fused deposition modelling (FDM) has the potential to enhance their clinical performance. However, this approach is restricted by issues such as material shrinkage and part warpage when HDPE is processed through the FDM technology. This review paper presents an overview of FDM of HDPE to produce facial reconstruction implants.

Correction of Mild-to-Moderate Sunken Upper Eyelids of Asians with Stromal Vascular Fraction Gel

Fat grafting is an efficient and safe procedure for the correction of upper eyelid sulcus deepening. Stromal vascular fraction (SVF) gel has been proven to be an ideal fat derivative and can be widely used for facial augmentation. We aimed to determine the efficacy of SVF gel for the correction of a mild-to-moderate sunken superior sulcus among Asian patients. Patients with a mild-to-moderate sunken superior sulcus underwent SVF gel grafting of the sunken upper periorbital area. The primary result was the quantitative volume difference in the superior sulcus region before and after grafting. This was evaluated through three-dimensional VECTRA® imaging. The secondary results included the aesthetic quantitative evaluation results (upper lid area and pretarsal space ratio), global aesthetic improvement scale (GAIS) score, and complications. Thirty-one patients with mild-to-moderate sunken upper eyelids were included in this study. The average unilateral injected amount was 1.235mL (± 0.171mL). The 1-year delta volume was 0.801 ± 0.086mL, and the effective survival volume was 65.3% (± 6.1%). The median preoperative pretarsal space and upper lid area ratio was 1.010 (± 0.150). The median postoperative pretarsal space and upper lid area ratio at 1year was 0.159 (± 0.031) (n = 62; P < 0.0001), indicating a significantly reduced sunken appearance. The average GAIS score was 2.174 (± 0.391). All patients were satisfied with their surgical outcomes. The reoperation rate was 12.9%. SVF gel is safe and effective for the treatment of a mild-to-moderate sunken superior sulcus and is associated with satisfactory clinical outcomes and short recovery times.

Major clinical evidence of cervicofacial liposculpture: a concise systematic review

Introduction: Liposculpture (LS) can complement cervicofacial aging surgery. Modern trends in face sculpting are expanding and adipose tissue transfer can result in optimal esthetic effects with minimally invasive techniques. Facial LS focuses on repositioning adipose tissue and increasing facial transition zones. This is accomplished using internal suspension sutures as well as with autologous fat grafting. Objective: To carry out a concise systematic review of the main clinical considerations and advances in facial and cervical liposculpture as an important aesthetic tool for dental surgeons. Methods: The rules of the Systematic Review-PRISMA Platform were followed. The search was carried out from November 2021 to February 2022 in Scopus, PubMed, Science Direct, Scielo, and Google Scholar databases. The quality of the studies was based on the GRADE instrument and the risk of bias was analyzed according to the Cochrane instrument. Results: Fifty articles were found involving facial liposculpture. A total of 30 articles were fully evaluated and 16 were included and developed in the present study. Considering the Cochrane tool for risk of bias, the overall assessment resulted in 10 studies at high risk of bias and 4 studies that did not meet the GRADE. Most patients who were involved in the studies showed improvements in facial augmentation and contouring. In patients with loss of facial volume, high-density fat transfer with SVF-gel facial injection resulted in significantly higher improvement scores and better patient satisfaction, with an improved/much improved esthetic appearance being observed. As a follow-up analysis of the studies, at an average of six months after completion, most patients were satisfied with the results. All procedures were well tolerated. Conclusion: According to the main clinical studies selected in the present study, cervicofacial liposculpture proved to be advantageous, with safety and efficacy.

Major clinical outcomes and analysis of the risk of bias of the advances in cervicofacial liposculture: a systematic review

&#x0D; Introduction: In the context of liposculpture, cervicofacial liposuction involves the application of negative pressure through a hollow cannula in the subcutaneous plane to gently avulse fat cells and accurately sculpt unwanted fat deposits on the face and neck. Furthermore, lipo contouring provides a versatile tool in the facial surgeon's arsenal to achieve the desired facial profile. In 2020, approximately 15.5 million cosmetic procedures were performed in the United States alone. Objective: A systematic review was carried out on the main clinical results, presenting studies on the risk of bias, and the advances in facial and cervical liposculpture as an important aesthetic tool for the dental surgeon. Methods: The rules of the Systematic Review-PRISMA Platform were followed. The search was carried out from November 2021 to February 2022 in Scopus, PubMed, Science Direct, Scielo, and Google Scholar databases. Results: 64 articles were found involving liposculpture. A total of 32 articles were fully evaluated and 14 were included and developed in the present study. Considering the Cochrane tool for risk of bias, the overall assessment did not result in significant risk of bias studies. The Funnel Plot showed symmetrical behavior. Twenty-five studies did not meet the GRADE. Most patients who were involved in the studies showed improvements in facial augmentation and contouring. In patients with loss of facial volume, high-density fat transfer with the facial injection of SVF-gel resulted in significantly higher improvement scores and better patient satisfaction. Conclusion: According to the main clinical studies selected in the present study, cervicofacial liposculpture proved to be safe and effective. In patients with loss of facial volume, high-density fat transfer with a facial injection of SVF-gel resulted in significantly higher improvement scores and better patient satisfaction. Still, the results of the studies showed that the level of self-confidence and mental health-related quality of life can be significantly improved after facial lipofilling treatment.

Dynamic muscle discord in the context of non-surgical lip enhancement

Dynamic muscle discord (DMD) is a fundamental concept in facial soft tissue augmentation with dermal fillers, particularly in perioral rejuvenation and lip enhancement. It is frequently observed in patients with facial skeletal and soft tissue deficiencies. The lack of adequate structural support may result in compensatory muscle hypertonicity or confer a mechanical advantage in certain muscle groups over their antagonistic counterparts. This discord in activity between the various muscle groups can affect the posture and profile of mobile facial features both at rest and during facial expression. Unfortunately, despite being a condition that commonly presents to varying degrees in patients seeking lip enhancement, DMD is often poorly diagnosed and undertreated. The author describes the causes, consequences and treatment of this condition in relation to the perioral region, as illustrated by a case study discussion.

Expert Recommendations on the Use of Injectable Poly-L-lactic Acid for Contour Deficiencies of the Buttocks.

Poly-L-lactic acid (PLLA) is an injectable biodegradable biostimulator that promotes collagen production and is approved for use in aesthetic facial augmentation. PLLA is well tolerated with minimal downtime and has demonstrated an excellent safety profile, as well as a longevity benefit of at least 2 years following injection. The robust safety and efficacy profile associated with PLLA for facial rejuvenation has resulted in a growing interest in the use of PLLA for other body areas such as the buttocks, which are an increasingly popular target of aesthetic enhancement. Patient goals for gluteal enhancement include improving contour and texture, reduction in visible cellulite and increased volume and lift. In order to achieve optimal outcomes and patient satisfaction, it is essential to ensure correct usage of PLLA; however, there is currently a lack of guidelines and expert recommendations in this area. This report reflects consensus recommendations for the use of PLLA in non-invasive buttock contouring, including patient selection, PLLA preparation, dosing, injection and, efficacy and safety assessments.
