Hyaluronic acid (HA) filler injection is widely used for soft-tissue augmentation. Complications associated with HA filling are not uncommon; however, HA-induced alopecia is a rarely reported complication that could result in severe secondary psychological trauma. The etiology, clinical traits, treatment strategies, outcomes, and possible reversibility of HA-induced alopecia have not been characterized. Here, we report a case in which bilateral temple injections of 6.5 mL of HA led to persistent pain over the left scalp for several days...

The purpose of this article is to update the changes to the author's protocols used to manage acute filler related vascular events from those previously published in this journal. For lack of a better term, this new protocol has been called the High Dose Pulsed Hyaluronidase (HDPH) protocol for vascular embolic events with hyaluronic acid (HA) fillers. The initial protocol used involved many different modalities of treatment. The current protocol is exceedingly simple and involves solely the use of hyaluronidase in repeated high doses...

Background: Vision loss is a rare but serious complication of facial hyaluronic acid (HA) filler injection, for which there is no proven rescue therapy. Retrobulbar hyaluronidase injection is advocated by many plastic surgeons as an emergency treatment, but has not been carefully assessed for its efficacy. Objectives: To evaluate the efficacy of retrobulbar hyaluronidase injection as a rescue treatment for vision loss caused by HA filler embolization. Methods: Patients with vision loss caused by HA filler embolization were treated with retrobulbar hyaluronidase injection...

While surgical site preparation has been extensively studied, there is little information about resistance of skin microbiota in the biofilm form to antimicrobial decontamination, and there are no quantitative models to study how biofilm might be transferred into sterile tissue/implant materials during injections for joint spine and tendon, aspiration biopsies and dermal fillers (DF). In this work, we develop two in vitro models to simulate the process of skin preparation and DF injection using pig skin and SimSkin (silicone) materials, respectively...

Siliconomas are subcutaneous nodules that usuallyappear as a consequence of the migration of freesilicon implanted in other locations. They are morefrequent in women with abnormal breast implants,such as poly implant prostheses (PIP), but they may alsoappear after illegal injection of free silicone. We reporta 57-year-old woman who attended our Dermatologyclinic complaining of relapsing facial panniculitis ofunknown origin. After a thorough work-up, thesenodules were determined to be the consequence ofdermal filler made with fluid silicone, which had beeninjected 20 years prior...

BACKGROUND: Hyaluronic acid (HA) gel fillers represent most soft tissue augmentation procedures currently used, because they have lower rates of complications compared with other materials. Many patients do not consume an entire syringe of filler but may require a retouch or intermittent augmentation after some time. The remaining material is commonly stored in a specific environment for reuse by the same patient. OBJECTIVE: There are an insufficient number of recommendations concerning the safety of storing and reusing dermal fillers in the literature because of the paucity of studies...

BACKGROUND: Facial rejuvenation is an expanding field with an increasing number of treatment modalities. Several non-autologous filler materials are available for soft tissue augmentation. Calcium hydroxylapatite (CaOH) is aimed at increasing collagen neosynthesis and thereby producing long term augmentation effects. Despite a multitude of observational reports, the field is suffering from lack of quantitative morphometic evaluation methods. OBJECTIVE: The objective of this proof-of-principle study was to investigate whether the effects of facial tissue augmentation with CaOH (Radiesse™) can be quantified and followed up using 3D surface scanning...

There is no safe and effective standard method for glans penis augmentation. Furthermore, there has been scant research on glans penis augmentation due to a poor understanding of glans anatomy, technical difficulty, and a lack of suitable substances for augmentation. Cross-linked dextran gel is a newly developed filler for soft-tissue augmentation. We evaluated the efficacy and safety of using a novel technique to inject cross-linked dextran gel for glans penis augmentation during a 24-week follow-up study...

The aim of this paper is to compare 2 hyaluronic acid gel fillers from the same Swiss manufacturer and with the same indications: filling of line wrinkles and folds. The products differ by their cross-linking process. With very simple easy-to-reproduce tests, cohesivity and resistance to traction forces were examined. Also, both gels were injected under ultrasound control in the mid reticular dermis of three subjects. The papules were controlled under ultrasound and biopsies at D0 and D15. Results showed significant differences between the 2 gels in all the tests...

Hyaluronic acid (HA) is one of the natural components of the human body with high biocompatibility, biodegradability, and nonimmunogenicity, which makes it the ideal biomedical filling agent currently available. However, for many medical practitioners, HA filler injections remain a relatively new item to carry out. Learning while practicing, it is inevitable to encounter some difficulties and adverse reactions in its application. Here we report two cases of adverse reactions to HA-based filler injections, including anaphylactic reaction on the face and vascular thrombosis after augmentation rhinoplasty with HA filler...

BACKGROUND AND AIMS: Mucosal lift is critical for successful endoscopic treatment. Normal saline solution (NS) is widely used as the submucosal filler, but its short persistency restricts clinical endoscopic submucosal dissection (ESD) procedure. In this study, thermo-sensitive isopentane was introduced for submucosal injection. With a 27.8°C boiling point, liquid isopentane could be easily applied, whereas gasification inflation could provide great support for submucosal lifting at body temperature...

REVIEW
Seongmu Lee, Michael T Yen
There has been an increased recognition for the role volume deflation plays in the aging periorbital area, and as such, rejuvenation strategies to augment and restore volume have developed and evolved. Hyaluronic acid fillers provide an efficient option for volume augmentation with good efficacy, longevity, and safety. An understanding of the changes in the upper and lower periocular area due to aging, the meticulous identification of focal hollows, and the precise delivery of filler to these areas can smooth contours and restore a rejuvenated periorbital area...

Polymer/metallic particle nanocomposites or nanodielectrics can exhibit colossal dielectric constants with a relatively low dissipation factor under low electric fields and thus seem to be promising for high-energy density dielectric capacitors. To study this possibility, this work focused on the dielectric performance and loss mechanisms in polypropylene (PP)/aluminum nanoparticle (nAl NP) composites under high electric fields. Phosphonic acid-terminated poly(ethylene-co-1-butene) was grafted to the Al2O3 surface layer on the nAl NPs in order to achieve reasonable dispersion in the PP matrix...
