Hydrogels have emerged as a highly interdisciplinary topic as they play a significant role for a vast number of applications. They have been studied extensively as materials for contact lenses, wound dressing and as filler material in soft-tissue augmentation, in which classical polymer backbones such as hydroxyethylmethacrylate (HEMA) are typically employed. More recently, polysaccharides have received attention, particularly in the fields of regenerative medicine and tissue engineering, as ideal candidate materials for artificial extracellular matrices (ECM)...

In addition to cosmetic use, filler materials are frequently employed for reconstruction of contour defects. Scars and tissue defects after accidents, surgery and irradiation are also ideal indications for injectables. The ideal filler should be easy to inject, easy to form, and should remain in the body as long as possible. It should neither be allergenic or carcinogenic nor susceptible to infections or biofilms, but still potentially reversible, temperature-stable, and cheap. There is still no augmentation material that fulfils all of these criteria...

INTRODUCTION: Cosmetic injections of dermal fillers or fat could cause ophthalmic artery embolism and even blindness, the high-risk regions of which are considered glabellar, nasal dorsum, and nasolabial fold. Understanding anatomy of the related arteries is important for a physician to safely perform filler injections. To investigate the mechanisms of ophthalmic artery embolism following the injections, cadaver anatomy was studied. METHODS: Ophthalmic artery, facial artery, their branches, and anastomoses among them were anatomized in 12 fresh cadavers...

Techniques for the administration of injectable fillers and neuromodulators for facial aesthetic rejuvenation and enhancement continue to evolve. As the number of physicians with limited experience in providing aesthetic treatments expands, the need for guidance and training from more experienced injectors has become apparent. The use of a slow, careful, and methodical injection technique is imperative in all treatment settings and for all facial areas. Constant attention to local anatomy, particularly arteries, veins, and nerve bundles, is critical for minimizing complications...

Minimally invasive aesthetic and cosmetic procedures have increased in popularity. Injectable dermal fillers provide soft tissue augmentation, improve facial rejuvenation and wrinkles, and correct tissue defects. To investigate the use of adipose‑derived stem cells integrated with a hyaluronic acid based gel as a dermal filler, the present study used cytotoxicity studies, proliferation studies, adipogenic and osteogenic differentiation, apoptosis assays and scanning electron microscopy. Although hyaluronic acid induced low levels of apoptosis in adipose‑derived stem cells, its significantly promoted proliferation of adipose‑derived stem cells...

Performing rhinoplasty using filler injections, which improve facial wrinkles or soft tissues, is relatively inexpensive. However, intravascular filler injections can cause severe complications, such as skin necrosis and visual loss. We describe a case of blepharoptosis and skin necrosis caused by augmentation rhinoplasty and we discuss the patient's clinical progress. We describe the case of a 25-year-old female patient who experienced severe pain, blepharoptosis, and decreased visual acuity immediately after receiving a filler injection...

The use of cosmetic fillers agents in orofacial region has become more often used for esthetic concern. Although adverse effects are rare, some patients may develop foreign body reaction to such fillers. Hyaluronic acid (HA) is a biomaterial in the spotlight, because it is normally present in several tissues of human body. The aim of this study was to report a case of a 54-year-old white woman with granulomatous reaction to the HA located in the lips. In addition, a review of the English-language literature of all previously described cases of this condition in oral and perioral region was performed...

Aesthetic surgery of female external genitalia has gained increasing popularity over the past decade, with reduction of the labia minora (labiaplasty) being the procedure most commonly requested and performed. Female external genitalia lose elasticity and volume with age, but few studies describe the techniques for labia majora augmentation. Currently, very few studies have investigated the effectiveness and safety of labia majora augmentation with hyaluronic acid (HA) injection. This study aims to evaluate the effectiveness and safety of labia majora augmentation with hyaluronic acid filler injection...

Neauvia Stimulate® is a biocompatible, injectable hyaluronic acid (HA) filler (26 mg/ml) PEG cross-linked with 1% of calcium hydroxyapatite (CaHA) for facial soft-tissue augmentation that provides volume to tissues, followed by a process of neocollagenesis for improving skin quality. The aim of the present study is to evaluate the possible modulation of collagen synthesis after treating human fibroblasts cultured in vitro with the product (Lot. 160517-26-1/2 PEG). The experimental model proposed, despite being an in vitro system, allows the derivation of useful information to predict the possible activity of the product in further in vivo application...

To correct skin imperfections, aesthetic medicine today makes use of injectable dermal fillers that allow filling skin by increasing the volume of soft tissue. Currently, there are many fillers usable for their excellent biocompatibility and low allergic reactions that ensure good results and good compliance. Among these, the most widely used filler is Human Plasma, obtained by centrifugation from patient blood and processed through cycles of centrifugation and heating, until it becomes a gel. In this work, we evaluated the effect of the Plasma on fibroblasts behavior in terms of cell viability, survival, growth and collagen production...

BACKGROUND: Open gingival embrasure, so called the "black triangle", is one of the unsolved dilemmas in adult dentistry. Although various techniques were introduced to improve the black triangles, the lack of reproducible experimental models has prevented the development of successful protocols to regenerate or to compensate the loss of the interdental papilla. Therefore, the objective of this study was first to develop a reliable animal model of open gingival embrasure, and then to validate a minimally invasive injection technique using the hyaluronic acid (HA) filler to augment the interdental papilla...

Common side effects during hyaluronic acid filler injections are typically mild and reversible, but several reports of blindness have received attention. The present study focused on orbital symptoms combined with blindness, aiming to classify affected patients and predict their disease course and prognosis. From September of 2012 to August of 2015, nine patients with vision loss after filler injection were retrospectively reviewed. Ptosis, ophthalmoplegia, and enophthalmos were recorded over a 6-month follow-up, and patients were classified into four types according to periocular symptom manifestation...

INTRODUCTION: The appeal of hyaluronic acid fillers for facial soft tissue augmentation is attributable to both an immediate aesthetic effect and relatively short recovery time. Although recovery time is an important posttreatment variable, as it impacts comfort with appearance and perceived treatment benefit, it is not routinely evaluated. Natural-looking aesthetic outcomes are also a primary concern for many patients. MATERIALS AND METHODS: A single-center, noncomparative study evaluated the time (in hours) until subjects return to social engagement (RtSE) following correction of moderate and severe nasolabial folds (NLFs) with RR (Restylane(®) Refyne)(®) and RD (Restylane Defyne), respectively...

BACKGROUND: Fat grafting has emerged as a reference procedure in daily plastic surgery practice. Unpredictable fat resorption is the main clinical problem. For this purpose, the addition of PRP to enhance fat revascularization is now an easy and popular procedure. However, no consensus exists regarding the respective volume of fat and PRP used to obtain the ideal mixture. This study investigated the rheological properties of microfat mixed with different proportions of PRP. Results obtained were compared with commercialized hyaluronic acid fillers...

Facial nerve paralysis can occur due to infection, inflammation, trauma, surgery, and tumors. It leads to facial asymmetry, impaired oral competence, articulation deficits, and psychological problems. Treatment options include physical therapy, static slings, nerve and muscle transfers, blepharoplasty, brow lift, and chemodenervation with botulinum toxin. We report the case of a 66-year-old Caucasian female with permanent facial paralysis following middle ear surgery. The facial asymmetry was treated successfully with botulinum toxin A injection, hyaluronic acid dermal filler injection, and a thread-lift procedure...
