Abstract
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.

Abstract
Background and Aims Hyaluronic acid (HA)-based injections are used worldwide to improve skin defects associated with aging and ultraviolet light/environmental exposure. HA formulations developed according to molecular weight or with additional components, for example, cross-linking reagents, are limited by their low biological activity and concentration limit. NAHYCO™ technology has enabled the production of hybrid cooperative complexes (HCCs) of low and high molecular weight HA. Developed for injection into the fat compartments of the face and previously demonstrating potential benefits for adipose tissue restoration, Profhilo Structura® is a new 2 mL HCC formulation comprising low molecular weight HA (45 mg/mL) and high molecular weight HA (45 mg/mL). To evaluate the efficacy and tolerability of Profhilo Structura® to restore adipose tissue compartments in the lateral cheek fat compartment. Methods Fifty healthy enrolled subjects received two injections, 1 month apart, and were evaluated 3 months posttreatment. Investigators performed clinical evaluations (Facial Volume Loss Scale [FVLS] and Wrinkle Severity Rating Scale [WSRS]) at different time points. Subjects also completed self-evaluation assessments following treatment. Results A significant improvement in FVLS and WSRS clinical scores after the first treatment was observed; treatment benefit was maintained 3 months after treatment completion and confirmed by subject self-assessment. Most participants reported an improvement, particularly a marked reduction of wrinkles and increased skin firmness. No serious adverse events were reported, confirming the excellent safety profile of HCC injectable devices. Conclusions Overall, the study highlighted the efficacy and tolerability of the studied medical device proving its effect on adipose tissue.

Abstract
Facial aesthetic procedures have become increasingly popular and complex, making knowledge of facial anatomy crucial for achieving desired outcomes without complications. Some of the most common procedures include blepharoplasty, bichectomy, face-lifts, facial implants, thread lifting, and fillers. Blepharoplasty and bichectomy are surgical procedures that respectively aim to restore youthful contours to the periorbita and create a slimmer lower face by removing Bichat fat from the maxillofacial region. Facial implants are used for aesthetic augmentation of the skeletal structure and restoration of facial contour by using biomaterials or autogenous bone grafts. Face-lift surgeries involve incisions and removal of excess skin, and thread lifts involve less invasive procedures performed by inserting threads beneath the skin, with the aim to lift the skin and thus reduce wrinkles and sagging. Fillers improve wrinkles and loss of facial volume, with biologic types made from animal, human, or bacterial sources (such as hyaluronic acid), while synthetic fillers include substances such as paraffin, silicone, calcium hydroxyapatite, polymethylmethacrylate microspheres, polyacrylamide hydrogel, hydroxyethyl-ethyl methacrylate, and poly-l-lactic acid. Synthetic fillers can be classified as rapidly resorbable (<12 months), slowly resorbable (<24 months), or permanent. Imaging modalities such as US, CT, and MRI can help identify and analyze each type of facial aesthetic procedure or filler, as well as their possible complications such as foreign-body granuloma, noninflammatory nodule, late intermittent persistent edema, filler migration, infection, or complications after removal of the buccal fat pad. ©RSNA, 2023 Quiz questions for this article are available through the Online Learning Center The online slide presentation from the RSNA Annual Meeting is available for this article.

Abstract
Understanding facial anatomy is a key aspect for successful treatment of age-related changes manifested to facial tissues. Namely, changes to the facial muscles and their connective tissue framework result in an increased soft tissue laxity, leading to wrinkling, sagging, and altered texture. This review elaborates on the use of novel high intensity focused electrical stimulation (HIFES) and Synchronized RF technology to improve facial muscle tone and skin structure, focusing on the technology background and clinical aspects.

Abstract
BACKGROUND Rhinoplasty is becoming increasingly frequent as the pursuit of aesthetics by people accelerates. In recent years, the proportion of people opting for rhinoplasty injections has gradually increased. This has led to numerous reports citing catastrophic postoperative complications such as skin necrosis, cerebral infarction, and visual impairment. AIM The aim of our report is to discuss the possible etiological factors for this post-rhinoplasty complication and provides a rationale for HA injection history as a risk factor in rhinoplasty. METHODS We report a rare case that received nasal HA injections in the past without any untoward incident. She opted for a second rhinoplasty 2 years after her initial nasal HA injections. This second intervention led to post-injection loss of vision in one eye and cerebral infarction. Following clinical and radiological examination, digital subtraction angiography (DSA) and superselective intra-arterial thrombolysis were performed. RESULTS The patient did not develop disuse exotropia or ocular atrophy, but the left eye remained without light perception, which implies that intra-arterial thrombolytic therapy may be a positive and effective method to maintain the normal appearance of the eye. CONCLUSION It is advisable for patient safety to maintain a long interval of time between hyaluronidase injection and repeat rhinoplasty. Clinicians should become familiar with the anatomical peculiarities of the patient and be gentle during the rhinoplasty procedure.

Abstract
The facial skeleton is foundational for facial aesthetics. We describe an alternative technique for cosmetic chin augmentation that does not require alloplastic implants, osseous genioplasty, or autologous bone harvesting. In this new innovative technique for chin augmentation, tissue bank allograft cancellous bone chips serve as a scaffold for bony ingrowth. The use of bone chips allows for aesthetic contouring with small adjustments in the facial skeleton. The objective of this paper is to provide further information on this novel technique as well as demonstrate the efficacy and safety of tissue bank allograft cancellous bone chips as an alternative graft material for cosmetic chin augmentation. Retrospective review of patients who underwent chin augmentation with cancellous bone chips from July 2015 to March 2019 was performed. Photographic results from several patients were included. No patients developed infections, required re-operation, or went on to have explantation of the graft material. Initial results suggest cancellous bone chips are a safe, efficacious alternative graft material for cosmetic chin augmentation.

Abstract
AIM Dermal fillers have been progressively used for cosmetic procedures. Concurrently, the rates of filler complications have also increased. The aim of this study is to describe the clinical management and treatment we performed in patients with complications occurred after filler injection. METHODS From March 2000 to February 2020, 197 patients have been evaluated for complications due to filler injection. For each patient type of material, symptoms and signs were recorded. Ultrasound evaluation was used to obtain information about the type, amount and location of the injected material. Magnetic Resonance Imaging was performed in those patients who were candidate for surgery. Based on the clinical manifestations, we performed a targeted therapy. RESULTS The local and systemic medical therapy allowed us a complete remission of the clinical signs and symptoms in all patients presented with edema and erythema. We obtained optimal results with surgery, where a complete removal of the injected material was possible. In all the cases in which the complete removal of the infiltrated area could have led to functional impairments, we performed partial removal with poor outcomes. CONCLUSION We observed complex clinical manifestations in the patients subjected to permanent fillers. An accurate knowledge upon the effects of the materials on tissues, a specific instrumental evaluation and a targeted therapy are crucial. We suggest the use of absorbable fillers. Patient should be subjected to filler implant in authorized structures by an expert specialist with experience in filler injection and with a thorough knowledge of the anatomical structures.

J Cosmet Dermatol 2022; 21:940-948. [PMID: 35020250 DOI: 10.1111/jocd.14744] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/19/2021] [Revised: 12/17/2021] [Accepted: 12/29/2021] [Indexed: 11/30/2022]
Abstract
BACKGROUND Hyaluronic acid (HA) fillers are known to be effective for the correction of facial wrinkles and folds, but there is no clinical study that compares the efficacy of small-to-medium-particle HA fillers and large-particle HA fillers for the correction of nasolabial folds (NLFs). Moreover, injection depth also plays an important role in the correction of NLFs as well as improvement of facial aesthetics. OBJECTIVES To assess the efficacy, safety, and durability of a small-to-medium-particle HA filler, Restylane, and a large-particle HA filler, Yishumei, as well as the effect of injection depth in the correction of moderate-to-severe NLFs and facial aesthetics in a Chinese population. METHODS This 52-week, prospective, randomized, double-blind study enrolled 100 participants with moderate-to-severe NLFs. The participants were randomized to receive either Restylane (Group A) or Yishumei (Group B). Group A and Group B were further randomly divided into a superficial injection group (Group A1 & B1) and a deep injection group (Group A2&B2) according to injection depth. Improvement in the Wrinkle Severity Rating Scale (WSRS) score and Global Aesthetic Improvement Scale (GAIS) and participants' satisfaction were evaluated as endpoints. All adverse events were monitored throughout the study. RESULTS The treatments were well tolerated by all the participants. All four groups showed a reduction in their mean WSRS scores and GAIS scores by week 12. At week 24, the WSRS and GAIS scores did not change in Group A1 and A2, while participants in Group B1 and Group B2 had higher WSRS and GAIS scores than those in the previous weeks. By week 52, the WSRS scores in all the groups returned to almost baseline levels. The mean FACE-Q scores increased compared with the baseline scores in all groups through week 24. Most participants were satisfied with their treatment, and no meaningful differences were found between the fillers in terms of participant satisfaction. The most common adverse events were swelling, redness, and tenderness at the injection site, but they resolved spontaneously without treatment. CONCLUSION The two HA fillers had good therapeutic effect on NLFs in the early stage of treatment, but Restylane had a more prolonged effect. Moreover, compared with the superficial injection, the deep injection provided slight midface lifting and improved facial aesthetics.

Abstract
Recently, the use of noninvasive facial cosmetic procedures has been widely disseminated. In the face, cosmetic fillers, threads, and implants are used to reduce or delay the effects of aging or adjust facial defects caused by trauma or disease. The dentist or dental specialist may encounter these materials in the radiographic images of their patients. There are few reports in the dental literature describing the radiographic appearance of some materials along with the diseases they mimic. As the procedures and materials advance and evolve, dentists and dental specialists must be aware of their radiographic appearance to avoid errors in diagnosis. This is a report of two cases that include panoramic radiography and CBCT scan. Among these cases, there is an unusual appearance of a cosmetic filler due to a subperiosteal injection method. Moreover, it will discuss common types of cosmetic materials used in the face and their imaginological appearance. This is the key to dentists and dental specialists due to increasing use of facial cosmetic materials and a parallel increase in the use of cone beam CT and chances to encounter such findings.

Abstract
ABSTRACT Dermal filler injections, one of the most commonly performed procedures in facial esthetic surgery, are rising in popularity. This has also led to an increase in nonmedical grade filler injections performed by nonmedical personnel, including that of injectable silicone. Surgical removal of silicone fillers is challenging, as the hydrophobic material often disperses within the soft tissue as droplets. This can lead to a systemic inflammatory reaction requiring steroid treatment. MRI localization of the filler material does not enable intraoperative guidance, and palpitation of the material is challenging since the filler droplets are often too small to palpate and located in multiple planes. We present a case demonstrating the advantages of utilizing intraoperative ultrasound to localize and silicone filler material. Utilizing this technique, we were able to achieve a high degree of excision of silicone filler material and the patient was able to stop her previous necessary immunosuppressive steroid regimen successfully.

Penile girth augmentation by injectable fillers: a comprehensive review of imaging features and inflammatory complications. Abdom Radiol (NY) 2021; 46:1703-1717. [PMID: 33040174 DOI: 10.1007/s00261-020-02788-w] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/17/2020] [Revised: 09/18/2020] [Accepted: 09/27/2020] [Indexed: 10/23/2022]
Abstract
Despite the extensive controversy and debate of penile girth augmentation, high demands for such procedures are increasing. Penile inflammation is not common sequel after penile filler augmentation, but when it occurs, it has serious complications that sometimes necessitate emergency surgical intervention. Imaging with a variety of modalities, including ultrasonography, magnetic resonance imaging, and ascending urethrogrphy plays a paramount role in the detection and assessment of these conditions. Inflammatory conditions after penile girth augmentation using injectable fillers are ranging from local granuloma to penile abscess formation or diffuse cellulitis that may extend to the scrotum, perineum or deep pelvic organs. Rapid diagnosis and evaluation of extensions are important to avoid associated morbidity and permanent deformity. Our purpose is to provide a practical review of relevant penile anatomy, imaging appearance and injection technique of different types of subcutaneous fillers used in penile girth augmentation, and inflammatory complications that may occur after these procedures. Brief descriptions of patient clinical information and imaging features of inflammatory complications will be included and correlated in actual cases.

Abstract
BACKGROUND Biphasic hyaluronic acid (HA) fillers have been used extensively to improve facial skin. However, in some cases, the skin surface is irregular because of the premature loss of HA solution. We propose a new biphasic filler (G-filler) to overcome this problem by using small particles of HA hydrogel instead of HA solution, which can provide a smooth skin surface and good durability. METHOD We evaluated the rheologic properties of G-filler and its physiologic effects after subcutaneous injection in a mouse model by histologic analysis. RESULTS The G-filler showed a similar elastic modulus (G') and complex viscosity (η*) as the conventional biphasic filler, but had a higher viscous modulus (G″) than the conventional monophasic filler. The highest material elasticity (tan δ) value and the lowest percentage elasticity value indicate the rheologic properties of G-filler are closer to those of liquids. After subcutaneous injection of G-filler, collagen content (~ 2-fold) and elastin fibers (~ 6.5-fold) were significantly increased at 12 weeks compared to those of the saline group. Fibronectin (~ 2.6-fold) and the laminin-immunolabeled cell number (~ 6-fold) were also significantly increased at 12 weeks. Significant increases in the CD31-immunoreactive cell numbers of the G-filler groups were observed at 2, 6, and 12 weeks (~ 3.7-fold) compared to those of the saline groups. There were no significant differences between the G-filler and saline groups in patterns of skin thickness and inflammatory cell numbers around loading sites. CONCLUSION These findings demonstrate that the injection of a new biphasic filler with improved rheologic properties can effectively stimulate extracellular matrix production and angiogenesis without safety concerns.

Abstract
Background Combinations of minimally invasive procedures (MIPs) are often used in aesthetic treatments and are increasingly considered as the new standard of care. Three agents with specific properties are available in this perspective: a polycaprolactone (PCL)-based collagen stimulator, a poly-L-lactic acid (PLLA)- and a poly-glycolic acid (PLGA)-based resorbable suspension suture with a 3D-cone technology, and a cross-linked hyaluronic acid (HA). Objective To develop the first practice guidelines on rejuvenation treatment of the face and the neck using combinations of these agents, whether associated or not with other widely used MIPs such as botulinum neurotoxins or energy-based devices. Methods A multi-disciplinary, multi-national board of plastic surgeons and dermatologists convened to develop guidelines using a predefined consensus method. The consensus was defined as ≥83% agreement rate between participants. Results Practice guidelines and algorithms, describing optimal procedure sequence and spacing, are proposed for the treatment of upper-, mid-, lower-face and neck, combining the PCL collagen stimulator, the PLLA/PLGA suspension sutures, and the cross-linked HA, whether associated or not with other MIPs. Conclusion These new guidelines provide general support to optimal management strategies. Individual treatment plans should be adapted according to the physician’s individual competence and the patient’s preferences.

Abstract
OBJECTIVE This review is primarily focusing on the legitimate concern about bacterial contamination after reuse of stored filling syringes and its associated risk of infections. METHODS A comprehensive literature review was done through searching the PubMed, Medline, Google Scholar, and ResearchGate without setting a time limit. The following search terms were used soft tissue filler, hyaluronic acid, or calcium hydroxylapatite AND sterility, safety, retouch, touch up, or reuse. RESULT Immediate replacing needles used in injection with a sterile substitute before storage was associated with no growth in one study (Archives of Facial Plastic Surgery, 11, 2009, 271) and growth in another study (Dermatologic Surgery, 2017, 43, 967). There was no reported infection in the only patient-based study that examined the adverse events among patients injected with stored hyaluronic acid filler syringes. CONCLUSION All published research showed that stored fillers are safe and do not increase the risk of biofilm formation.

Abstract
Minimally invasive procedures including neurotoxins, dermal fillers, deoxycholic acid, lasers, peels, and microneedling offer powerful, less permanent adjuncts to surgery that are highly effective in select patients. Injectables and skin resurfacing techniques target facial irregularities including wrinkles and fine lines, decrease in volume and contour, and unwanted fat. Determining the best approach for a given patient involves careful consideration of the patient's health conditions, unique anatomic characteristics, tissue quality, and desired results. A detailed understanding of facial anatomy, aesthetics, and techniques is necessary to master these approaches. This article addresses the spectrum of nonsurgical cosmetic procedures to rejuvenate and optimize the face.

Abstract
Purpose Aim of the study was to determine both clinically and by noninvasive instrumental evaluations the efficacy, tolerability and the duration of the effects of a new hyaluronic acid (HA) gel in human volunteers with moderate aging/photoaging. Patients and methods Eighteen volunteers (35–55 years) were enrolled in this single-center study. The subjects underwent five visits. The first visit was at baseline to determine the adherence to the inclusion criteria, followed by the first injection of the HA-based study product, and the second visit was at 48 hours after the injection. Two months later, a second injection was given (Visit 3) followed by a subsequent visit (Visit 4) after 48 hours. The last visit (Visit 5) was performed 5 months after the first injection. Clinical and instrumental evaluations as well as self-assessment by the subjects were recorded at each visit. Results A significant improvement of wrinkles’ grade around the eyes, vertical lip lines and wrinkles’ severity of nasolabial folds was recorded after the first injection and the effect increased after the second injection. Aging/photoaging grade and surface microrelief improved 2 months after the first injection procedure. These clinical improvements were paralleled by amelioration of instrumental skin profilometry and optical colorimetry. The treatments were very well tolerated by the volunteers as determined by the self-grading score. Conclusion The results confirm the good esthetic performance and the duration of the effect of the HA-based study product (Viscoderm® Hydrobooster) on dynamic facial wrinkles and/or static facial lines. These effects were particularly evident after the second injection and were accompanied by a good tolerability of the product.

Abstract
BACKGROUND Injectable fillers, such as those containing hyaluronic acid (HA), are increasingly used to smooth age-related facial creases and wrinkles. OBJECTIVE To compare efficacy and safety of a HA gel with lidocaine formulated by XpresHAn Technology (HARDL) with a HA gel without lidocaine produced by Hylacross technology (HAJUP) in the treatment of moderate-to-severe nasolabial folds. MATERIALS AND METHODS Subjects (n = 162) received initial and touch-up injections with HARDL and HAJUP on either side of the face. Investigator- and subject-assessed wrinkle severity was measured up to 48 weeks after final injection. RESULTS Mean (SD) Wrinkle Severity Rating Scale was improved by 1.1 (0.75) and 1.1 (0.68) with HARDL and HAJUP, respectively, at 24 weeks; improvements were sustained up to Week 48 with both treatments. Noninferiority of HARDL was demonstrated (mean difference -0.09 [95% confidence interval: -0.18 to -0.01], p = .032) at 24 weeks. Adverse events were reported in 43% subjects, 12% were treatment related, with a similar distribution for both treatments. CONCLUSION Effectiveness and safety profiles of HARDL and HAJUP were comparable.

Abstract
Clarification is needed regarding the definitions and classification of groove and hollowness of the infraorbital region depending on the cause, anatomical characteristics, and appearance. Grooves in the infraorbital region can be classified as nasojugal grooves (or folds), tear trough deformities, and palpebromalar grooves; these can be differentiated based on anatomical characteristics. They are caused by the herniation of intraorbital fat, atrophy of the skin and subcutaneous fat, contraction of the orbital part of the orbicularis oculi muscle or squinting, and malar bone resorption. Safe and successful treatment requires an optimal choice of filler and treatment method. The choice between a cannula and needle depends on various factors; a needle is better for injections into a subdermal area in a relatively safe plane, while a cannula is recommended for avoiding vascular compromise when injecting filler into a deep fat layer and releasing fibrotic ligamentous structures. The injection of a soft-tissue filler into the subcutaneous fat tissue is recommended for treating mild indentations around the orbital rim and nasojugal region. Reducing the tethering effect of ligamentous structures by undermining using a cannula prior to the filler injection is recommended for treating relatively deep and fine indentations. The treatment of mild prolapse of the intraorbital septal fat or broad flattening of the infraorbital region can be improved by restoring the volume deficiency using a relatively firm filler.

Abstract
In aesthetic medicine, there has been an ongoing search for an ideal dermal filler to offer zero complication rate. Polycaprolactone-based dermal filler (PCL) has been available since 2009. The purpose of the paper was to present a case of granuloma as a complication of PCL injection, which has not been reported so far by other researchers. A 68-year-old female was injected with PCL. One year later, nodules accompanied by bluish skin discoloration developed within the injection site. Ultrasound and histopathology studies were performed. The examinations confirmed the presence of foreign body granuloma after PCL, which makes it the first reported case worldwide. The published data analyses showed general lack of studies and case reports to address this issue. The PCL, like an injection of any soft tissue filler, may lead to serious complications, such as granuloma formation. This makes further research legitimate and necessary.

Abstract
Importance The US Food and Drug Administration approves Class III medical devices via the premarket approval pathway, often requiring clinical data on safety and efficacy. Manufacturers can submit incremental device changes via supplemental applications, which are not subjected to such vetting measures and can cause understudied changes that lead to drift from a device's original design. Objectives To characterize the postapproval changes to Class III dermatologic devices and to evaluate inconsistencies in the use of the premarket approval pathway. Design, Setting, and Participants This study was a cross-sectional retrospective cohort analysis of a public US Food and Drug Administration database for premarket approval of devices. Included were dermatologic devices approved by the US Food and Drug Administration between January 1, 1980, and November 1, 2016, through the premarket pathway for device approval. Main Outcomes and Measures Original devices were identified, and their supplements were characterized chronologically, by review track, and by modification category. Results The 27 dermatologic devices studied consisted of 14 injectables, 11 photodynamic therapies, a dermal replacement matrix, and a diagnostic imaging instrument. Supplemental applications are increasingly used: the data-requiring panel-track pathway was the least common approach (2.8% [16 of 562 supplements]), while the 30-day track, which does not require clinical data, was most frequently used (42.5% [239 of 562 supplements]). Four devices (14.8%) underwent low-risk recalls (Class II or Class III), and 10 devices (37.0%) were voluntarily withdrawn. Conclusions and Relevance As manufacturers make increasing use of supplemental applications, minor device changes may occur without supporting clinical data, which could pose a safety risk to patients.

Abstract
Background The range of fillers currently available for soft-tissue augmentation is constantly expanding. The latest advances in filler technology include collagen biostimulators that exert their esthetic effect by promoting neocollagenesis. One such product is the next-generation collagen biostimulator (Ellansé®) that demonstrates properties as yet unseen in soft-tissue fillers. It is composed of polycaprolactone (PCL) microspheres in an aqueous carboxymethylcellulose gel carrier. Given its specific characteristics and the number of areas that can be treated with this innovative product, experts’ recommendations were deemed necessary and are therefore presented in this paper with a specific focus on the indications, treatment areas and procedures as well as injection techniques. Methods A multinational, multidisciplinary group of plastic surgeons and dermatologists convened to develop recommendations with a worldwide perspective. This publication provides information on the specific characteristics of the product and focuses on the recommendations on the injection techniques. Results Recommendations on injection techniques are provided for the upper face, mid-face and lower face and zone by zone for each of these areas, as well as hands. Based on the particular anatomy of each area, the focus is on the techniques and devices of injection and the volume and depth of injection. The information is tabulated, and photos are presented for illustration. Conclusion These recommendations provide a guideline for physicians who wish to perform safe and efficacious treatment with the PCL collagen stimulator for face and rejuvenation with volume augmentation.

Abstract
BACKGROUND Auricular reconstruction is one of the most challenging procedures in plastic surgery. An adequate skin envelope is essential for cartilage framework coverage, yet few good options exist without additional surgery. We propose a novel method for minimally invasive tissue expansion, using hyaluronic acid (HA) filler to allow for single-stage ear reconstruction. OBJECTIVES To introduce the novel concept of HA filler for tissue expansion in ear reconstruction, and as an alternative to traditional expansion techniques. METHODS Macrolane is a large particle HA gel developed for large volume restoration. Expansion of the non-hair-bearing mastoid skin was performed in our clinic weekly or every other week. Final expansion was completed one week prior to reconstructive surgery. Tissue from one patient's expanded pocket was sent for histological analysis. RESULTS Ten patients underwent single-stage auricular reconstruction with preoperative expansion. Injection sessions ranged from 7 to 13 (mean, 9.7). Mean injected volume per session was 2.03 mL per patient, for an average total of 19.8 mL (range, 14.5-30 mL). There were no major complications. One minor complication required removal of exposed wire from the antihelix in the office. Hematoxylin and eosin stain revealed similar histology to that seen with traditional expanders. CONCLUSIONS This novel expansion technique using serial HA injections allowed for optimized skin coverage in single-stage ear reconstruction. The concept of tissue expansion using HA filler is a new frontier for research that may be applicable to other arenas of reconstruction. LEVEL OF EVIDENCE 4.

Injectable facial fillers: imaging features, complications, and diagnostic pitfalls at MRI and PET CT. Insights Imaging 2017; 8:557-572. [PMID: 28980212 PMCID: PMC5707222 DOI: 10.1007/s13244-017-0575-0] [Citation(s) in RCA: 34] [Impact Index Per Article: 4.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2017] [Revised: 09/02/2017] [Accepted: 09/05/2017] [Indexed: 01/31/2023] Open
Abstract
Injectable fillers are widely used for facial rejuvenation, correction of disabling volumetric fat loss in HIV-associated facial lipoatrophy, Romberg disease, and post-traumatic facial disfiguring. The purpose of this article is to acquaint the reader with the anatomy of facial fat compartments, as well as with the properties and key imaging features of commonly used facial fillers, filler-related complications, interpretation pitfalls, and dermatologic conditions mimicking filler-related complications. The distribution of facial fillers is characteristic and depends on the anatomy of the superficial fat compartments. Silicone has signature MRI features, calcium hydroxyapatite has characteristic calcifications, whereas other injectable fillers have overlapping imaging features. Most fillers (hyaluronic acid, collagen, and polyalkylimide-polyacrylamide hydrogels) have signal intensity patterns compatible with high water content. On PET-CT, most fillers show physiologic high FDG uptake, which should not be confounded with pathology. Abscess, cellulitis, non-inflammatory nodules, and foreign body granulomas are the most common filler-related complications, and imaging can help in the differential diagnosis. Diffusion weighted imaging helps in detecting a malignant lesion masked by injected facial fillers. Awareness of imaging features of facial fillers and their complications helps to avoid misinterpretation of MRI, and PET-CT scans and facilitates therapeutic decisions in unclear clinical cases. KEY POINTS • Facial fillers are common incidental findings on MRI and PET-CT scans. • They have a characteristic appearance and typical anatomic distribution • Although considered as safe, facial filler injections are associated with several complications • As they may mask malignancy, knowledge of typical imaging features is mandatory. • MRI is a problem-solving tool for unclear cases.

Abstract
BACKGROUND In part 1 of this study it was shown that liposuctioned fat could be a sufficient source of autologous collagen for use as a filler or in reconstruction. The collagen composition in liposuctioned fat was shown to form a cross-linked helical matrix composed of types II, III, and IV. Additionally, viable adipocytes and fibroblasts among other cells were found. OBJECTIVES The purpose of this research was to study the biology of this matrix after subsequent implantation compared to Juvederm (Allergan, Parsippany, NJ) common soft tissue filler. METHODS Fat was obtained from individuals undergoing routine liposuction and was processed by a two-step process to obtain a connective tissue matrix. The matrix was then cryo-frozen for a minimum of 4 weeks after which it was thawed and implanted in 46 nude mice. Juvederm Ultra was used as the control article and the animals followed for one year. RESULTS Liposuctioned fat was obtained from 10 individuals and processed as previously described. Mice were harvested at 3, 6, 9, and 12 months and histology obtained. There were no adverse effects from either article and the bio-reactivity rating was 0. The implanted collagen compared favorably to Juvederm at all stages and was found to be replaced by new collagen and fat. CONCLUSIONS A collagen matrix with viable cells for autologous use can be obtained from liposuctioned fat which has been processed and cryo-frozen. The material lasts at least one year and is slowly replaced by new collagenand fat. LEVEL OF EVIDENCE 5.

Abstract
INTRODUCTION Hyaluronic acid (HA)-based fillers are used for various cosmetic procedures. However, due to filler migration and degradation, reinjections of the fillers are often required. Methacrylated HA (MA-HA) can be made into injectable shape-memorizing fillers (three-dimensional [3D] MA-HA) aimed to address these issues. In this study, shape retention, firmness, and biocompatibility of 3D MA-HA injected subcutaneously in mice were evaluated. MATERIALS AND METHODS Fifteen mice, each receiving two subcutaneous injections in their back, were divided into four groups receiving HA, MA-HA, 3D MA-HA, or saline, respectively. Digital imaging, scanning electron microscope (SEM) and in vivo imaging system (IVIS), durometry, and histology were utilized to evaluate in vitro/vivo degradation and migration, material firmness, and the angiogenic (CD31) and immunogenic (CD45) response of the host tissue toward the injected materials. RESULTS Digital imaging, SEM, and IVIS revealed that 3D MA-HA fillers maintained their predetermined shape for at least 30 days in vitro and in vivo. Little volume effects were noted in the saline and other control groups. There were no differences in skin firmness between the groups or over time. Histology showed intact skin architecture in all groups. Three-dimensional MA-HA maintained its macroporous structure with significant angiogenesis at the 3D MA-HA/skin interfaces and throughout the 3D MA-HA. There was no significant inflammatory response to any of the injected materials. CONCLUSION 3D MA-HA showed remarkable tissue compatibility, compliance, and shape predictability, as well as retention, and thus might be suitable for various skin sculpting and soft tissue reconstruction purposes.
