Abstract
Background: As filler injections have become very common procedures worldwide, the number of complications has increased. However, there is a lack of systematized studies and precise classification of late and delayed complications. This study aimed to suggest new and reliable classifications and to characterize the clinical manifestations of late and delayed complications after filler injections.Methods: This retrospective study analyzed patients and suggested a new classification of delayed adverse effects related to filler injection. Several demographic and clinical findings were analyzed. Patients were classified into two types according to their clinical presentation: Type I (Localized) or Type II (Generalized).Results: Twenty-five patients were evaluated during a clinically active adverse event suspected to be related to fillers. The most common injected filler substance was hyaluronic acid (HA, 68.8%). 76% of the patients were classified with Localized complications. In the Generalized complications group, systemic symptoms were more common (p=0.002), the treatment response was poor (p=0.010), and fewer patients showed complete remission (p=0.007) than in the Localized complications group.Conclusions: We propose a simple new classification method for late and delayed complications after dermal filler: Localized and Generalized. We expect that this new classification could help provide appropriate treatment and predict patient prognosis.

Abstract
BACKGROUND Various substances are currently being used for cosmetic or postsurgical reconstruction reasons. Injecting of various materials into the face may provoke inflammatory or granulomatous reactions, infection and tissue necrosis. Among these reactions are foreign body granulomas. This study aims to describe the clinical characteristics of and therapeutic approaches used in patients with facial foreign body granulomas caused by the injection of various substances. METHODS From 2007 to 2020, a total of 64 patients visited our hospital due to inflammatory signs, palpable masses or surface irregularities. We reviewed patient characteristics, type of injected material, medical history and treatment outcomes. The treatment results were scored with patient satisfaction and statistical analysis of the treatment period was performed. RESULTS Most patients underwent conservative treatment followed by surgical treatment because of persistent symptoms; one patient did not require surgery. All patients reported good treatment results and satisfaction. The earlier the surgical treatment was performed, the shorter the treatment period and the higher patient satisfaction scoring. CONCLUSION Granulomatous changes to the face are an emerging concern in various cosmetic procedures and surgeries, including fillers, silicone implants and autologous fat injections. Our findings strongly suggest that patient symptoms require accurate diagnosis and surgical treatment.

Abstract
BACKGROUND Lipoatrophy of the face negatively impacts the quality of life and body image of individuals on antiretroviral therapy. Facial fillers can minimize the stigma associated with the human immonodeficiency virus (HIV). OBJECTIVES In this 5-year follow-up study, the author assessed the safety and efficacy of a permanent, non-biodegradable, polyacrylamide hydrogel for facial volume restoration, and compared the results with those of a previous 18-month follow-up study. METHODS Thirty-one HIV-positive individuals, initially enrolled in the study between January 2008 and January 2009, received treatment of facial wasting by injection of the polyacrylamide gel until complete volume restoration was achieved. Asepsis rules were strictly observed before and during each injection session. Patients evaluated their aesthetic outcomes on a visual analog scale. RESULTS Patient satisfaction was high. There was no occurrence of local infection, foreign-body reaction, or product during the 5 years of follow-up. Small, palpable, nonvisible nodules were recorded in nine cases. It appears that these same nodules were present in the 18-month study. It is believed that the nodules were caused by overfilling in the same site. CONCLUSIONS As supported by the initial 18-month study, polyacrylamide hydrogel filler appears safe and effective for the treatment of HIV-related lipoatrophy. With strict observation of asepsis rules and patient adherence to posttreatment instructions, this filler can be ideal for treating facial wasting in patients with HIV. LEVEL OF EVIDENCE 3 Therapeutic.

Foreign body granulomas after the use of dermal fillers: pathophysiology, clinical appearance, histologic features, and treatment. Arch Plast Surg 2015; 42:232-9. [PMID: 25798398 PMCID: PMC4366708 DOI: 10.5999/aps.2015.42.2.232] [Citation(s) in RCA: 111] [Impact Index Per Article: 12.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/07/2014] [Revised: 09/03/2014] [Accepted: 09/18/2014] [Indexed: 11/08/2022] Open
Abstract
A foreign body granuloma is a non-allergic chronic inflammatory reaction that is mainly composed of multinucleated giant cells. Foreign body granulomas may occur after the administration of any dermal filler. Factors such as the volume of the injection, impurities present in the fillers, and the physical properties of fillers affect granuloma formation. The formation of granulomas involves five phases: protein adsorption, macrophage adhesion, macrophage fusion, and crosstalk. The clinical and pathologic features of granulomas vary depending on the type of filler that causes them. Foreign body granulomas can be treated effectively with intralesional corticosteroid injections. Surgical excisions of granulomas tend to be incomplete because granulomas have ill-defined borders and moreover, surgical excisions may leave scars and deformities.

Abstract
BACKGROUND The late-stage clinical course, histopathologic analysis, and surgical salvage procedures after eventful cosmetic injection of hydroxyethylmethacrylate particles suspended in hyaluronic acid (DermaLive, marketed through Dermatech, Paris, France and Novamedical GmbH, Langenfeld, Germany) have been studied. The study was designed to present modified treatment guidelines, report results, and draw conclusions regarding the future management of patients with late-stage DermaLive complications. METHODS The study consulted and reviewed 21 patients with late-stage complications after facial implantation of DermaLive. Histology samples from excisional biopsies followed by radical surgical excision procedures were obtained and analyzed for nine patients. RESULTS The treated zones included nasolabial folds, forehead and glabella, lips, and the perioral and zygoma regions. The late-onset period between injection and first symptoms averaged 17.5 months. Lesions were mostly symptomatic, with discomfort, pain, swelling, and edema. Clinical aspects included bulging, palpable nodules, erythema, and scar formation. A positive correlation between patient age and the delay period was found. All surgically treated patients recovered well. The initial conservative measures achieved only partial success, whereas all nine surgically treated patients (43 %) demonstrated complete relief of their clinical symptoms. CONCLUSIONS Soft tissue augmentation with DermaLive led to a series of severe delayed adverse reactions. Sclerosing DermaLive granulomas demonstrated low success rates with conservative measures, whereas early radical surgical excision achieved good results.

Abstract
BACKGROUND This study aimed to assess and compare the tissue response to small- and large-volume injections of pure liquid silicone in rats. METHODS The study used 25 Sprague-Dawley rats. Two different injection sites were determined for a single rat, and 5000 centistoke liquid silicone was injected subdermally using 0.2-0.3 ml (small volume) and 1 ml (large volume) injections. After the injections, 15 animals were killed at 4 weeks and 10 animals at 10 weeks. Tissue responses were evaluated under a light microscope. RESULTS At week 4, the numbers of lymphocytes and neutrophils were higher in the small-volume injection group. At week 10, the number of neutrophils decreased, and the numbers of macrophages and foreign body giant cells increased in the small-volume injection group, whereas the intensity and type of infiltrate in the large-volume injection group did not change significantly. The thickness of the fibrous capsule was greater in large-volume injection group at weeks 4 and 10. The thickness of the fibrous capsule did not change significantly in either group through time. CONCLUSIONS Purified high-density liquid injectable silicone causes a low-grade and well-tolerated inflammatory response during the long term and can be used when given as small-volume injections.

Abstract
The objective of this study was to assess the safety and efficacy of injectable semipermanent and permanent dermal fillers, compared to other facial augmentation techniques, for the management of facial lipoatrophy as a result of highly active antiretroviral therapy (HAART) for HIV infection through a systematic review of the literature. A systematic search strategy was used to retrieve relevant studies. Inclusion of articles was by the application of a predetermined protocol, independent assessment by two reviewers, and a final consensus decision. One randomized controlled trial (RCT), one pseudo-RCT, two nonrandomized comparative studies, and seven case series were included for review. Injections with permanent and semipermanent dermal fillers improved subjective ratings of appearance and resulted in high patient satisfaction. Although short-term safety appeared favorable, of the seven studies that reported lumps, three studies reported these events in more than 40% of patients. Long-term safety data were lacking. Evidence suggests that permanent and semipermanent dermal fillers achieve their objective, which is to decrease the visible effects of HIV-associated facial lipoatrophy, with high patient satisfaction. Safety appears favorable in the short term, but further studies are required to determine long-term outcomes.

Abstract
A long-lasting filling product is accepted as such when, once the result has been obtained, no correction is required before the end of an arbitrary 2-year period. Other than silicone oil, which is not officially recognized for this indication in France, pure products can be distinguished from microparticle suspensions in a vector that will disappear in a short time. Flexible implants represent a totally separate entity and remain relatively little used since surgery is necessary for implantation. Our experience has led us to prefer monomolecular filling gels, in particular polyacrylamide hydrogels, with which we have had extensive experience, over gels with microparticles that we believe expose the patient to much greater inflammatory reactions that are sometimes difficult to overcome.

Abstract
Fillers are an important tool in the armamentarium of the physician combating aging phenomena. A wide variety of filler substances are now available that meet many, but by far not all, needs in aesthetic medicine. The most commonly used substances now are hyaluronic acid and collagen preparations that have slightly different indications, but collagen requires pre-use testing to rule out inflammatory complications. Poly-L-lactic acid has gained its place in the filling of adipose tissue wasting in HIV-infected patients. Autologous fat is easy to harvest and inject and has virtually no risk of adverse side effects. Permanent fillers may be of advantage but carry the risk of permanent adverse reactions. Skillful combination of different fillers as well as with botulinum toxin injections and other cosmetic procedures may give optimal results.

Abstract
As contemporary antiviral therapy provides patients who have HIV effective long-term management of their disease, the prevalence of facial HIV-associated lipoatrophy is increasing. Sculptra (Dermik Laboratories, Berwyn, Pennsylvania) (injectable poly-L-lactic acid) is US Food and Drug Administration approved for the treatment of HIV-associated lipoatrophy and has been shown to increase skin thickness for up to 2 years. The number of treatment sessions depends on the volume of deficiency to be treated. As is true for any cosmetic treatment, expectations must be carefully managed, especially considering the frequent need for multiple Sculptra treatments. The few adverse events resulting from poly-L-lactic acid injections consist mainly of subcutaneous nodule formation and local bruising.

Abstract
BACKGROUND Facial rejuvenation has long been dominated by surgical techniques that act on only two dimensions of the face, ignoring the third dimension (facial volume); therefore, a truly youthful look remains elusive. OBJECTIVES This paper aims to define the various surgical procedures employed by cosmetic surgeons that can be combined with alloplastic implants or injectable devices in order to restore lost facial volume. METHODS AND MATERIALS A search of the literature was performed. RESULTS Alloplastic augmentation and implants provide permanent restoration of facial volume, but require invasive surgery. Soft-tissue fillers include autologous fat, calcium hydroxylapatite, and a variety of polymers. Devices based on collagen and hyaluronic acids provide correction of superficial lines and folds, but cannot offer long-lasting restoration of facial volume. The only fillers that have been proven to augment facial volume are autologous fat, calcium hydroxylapatite, poly-L-lactic acid, polyacrylamide, poly-alkyl-imide, and methylpolysiloxane. CONCLUSIONS For optimal facial rejuvenation, the accepted surgical techniques of skin lifting and tightening could be combined with volumizing devices, thereby addressing ptosis, lines, folds, and volume loss.

Abstract
BACKGROUND With the introduction of highly active antiretroviral therapy (HAART), HIV/AIDS has become a more chronic disease. This increase in survival, however, has been accompanied by the occurrence of metabolic and morphologic changes known collectively as HIV-associated lipodystrophy. OBJECTIVE The objective was to evaluate the quantifiable improvement in facial wasting (lipoatrophy) after serial injections of poly-L-lactic acid (PLLA) as well as the long-term safety and durability of this material. METHODS AND MATERIALS A single-site, open-label study in which patients received up to six treatment sessions of injectable PLLA. Patients were followed for 12 months after treatment. Patients were evaluated for increase in total cutaneous thickness by skin calipers. Serial photographs and patient satisfaction and patient well-being questionnaires were undertaken throughout the study period. RESULTS Patients at the end of treatment exhibited a mean increase in skin thickness of 65.1% compared with baseline values. This correction was maintained throughout the 12-month follow-up period (68.8% at 6 months and 73% at 12 months). On a one to five scale, patient satisfaction was 4.5 at the end of treatment and increased to 4.8 at 12-month follow-up. No serious adverse events were reported. CONCLUSION PLLA is a safe and well-tolerated treatment option for HIV-associated lipoatrophy.

Abstract
OBJECTIVES The market for products and techniques that correct the visible signs of facial ageing is now huge. There is a diversity of devices and treatments now vying for a share of this growing marketplace, including polymer implants and injectable preparations that are based on an array of substances. The vast majority of these devices can only provide temporary correction of superficial lines and wrinkles, with volumetric augmentation being beyond their capabilities. The products and procedures suitable for the restoration of facial volume are discussed here. RESULTS The restoration of facial volume has long been neglected in cosmetic rejuvenation as surgical procedures increase skin tension but do nothing to restore the underlying facial volume, which is a subtle yet important characteristic of the youthful face. Fortunately, devices are now available which can augment facial volume for long periods of time or even permanently. These include implants based on expanded polytetrafluoroethylene and silicone rubber, which provide permanent restoration of volume, but require invasive surgery and do not age with the surrounding tissues eventually resulting in an unnatural appearance. The cosmetic rejuvenation market now abounds with various injectable devices, including: poly-L-lactic acid (PLLA), polymethylmethacrylate, collagens, hyaluronic acids, silicone and calcium hydroxylapatite. The choice of which one to use in practice is physician led, based on facial assessments, product characteristics and the desires of the patient. CONCLUSION Although there is a wealth of products available, injectable PLLA (Sculptra) can restore volume to the face providing a natural look. Not only are the results of volume augmentation using this device long lasting, but they are also safe.

Abstract
Liquid injectable silicone is a unique soft tissue augmenting agent that may be effectively utilized for the correction of specific cutaneous and subcutaneous atrophies. Although historical complications have occurred, resulting likely from the presence of adulterants and impurities, modern purified silicone products approved by the Food and Drug Administration for injection into the human body may be employed with minimal complications when strict protocol is followed. In this article the present authors review the history and controversy regarding silicone as well as describe the appropriate indications, patient selection, instrumentation, treatment protocol, and anticipated complications involved with the use of liquid injectable silicone for soft tissue augmentation. Although its use is controversial, the present authors maintain that liquid injectable silicone is an important and effective augmenting agent for the long-term correction of scars and facial contour defects such as HIV facial lipoatrophy. Furthermore, it is a treatment modality deserving of continued investigation.

Abstract
Lipoatrophy (LA) is a form of lipodystrophy, characterized by volume depletion caused by fat loss in the limbs, buttocks, and face. Facial volume loss is the most obvious outward sign of LA because it alters the facial contours in the cheeks, temples, and orbits. Lipodystrophy and LA are most commonly seen in patients with HIV on highly active antiretroviral therapy (HAART), which was introduced in the mid-1990s for the management of HIV, and is currently considered the mainstay therapy for HIV-infected patients. However, the etiology of LA is likely multifactorial as underlying patient conditions, including duration and severity of HIV and increasing age, have also been found to contribute to its occurrence. The volume loss of LA can be very dramatic with some patients exhibiting no signs of facial fat. As a result, many HIV-infected patients with associated LA suffer from psychological and lifestyle effects, which can lead to noncompliance with HAART. Thus, increases in facial volume and improvement in morphology is anticipated to reduce anxiety caused by LA in HIV-infected patients, and improve quality of life. This review discusses the benefits and limitations of several treatment options available to correct the volume depletion associated with LA, including antiretroviral switching, permanent surgical implants and injectables, poly-L-lactic acid, collagen, and hyaluronic acid derivatives.

Abstract
Leptin and adiponectin represent two newly discovered adipose tissue derived hormones with important roles in energy homeostasis and insulin resistance. Their interrelations with the manifestations of the HIV associated metabolic syndrome and specific somatomorphic changes i.e. fat redistribution is reviewed. A synopsis of published studies is presented and the potential role of leptin and adiponectin is discussed. We have described an association of the HIV metabolic syndrome with a state of reduced insulin sensitivity due to adiponectin deficiency. The metabolic syndrome is also accompanied by leptin deficiency in lipoatrophic subjects and possibly by a leptin resistance state in lipohypertrophic patients. Adiponectin and / or leptin therapy in a manner similar to other leptin deficiency states may assist in the future management of such patients.
