The Risk of Skin Necrosis Following Hyaluronic Acid Filler Injection in Patients with a History of Cosmetic Rhinoplasty.

As the number of patients using dermal filler for face augmentation increases, the number of adverse events associated with injection may increase. Unpredictable repositioning of blood vessels and a more tenuous blood supply in the operated nose may increase the risk of ischemia, necrosis and vascular embolism following the filler injection.

A Multi-Center, Open-Label, Prospective Study of Cannula Injection of Small-Particle Hyaluronic Acid Plus Lidocaine (SPHAL) for Lip Augmentation.

BACKGROUND: The use of blunt-tipped microcannulas for injection of hyaluronic acid (HA) filler in the lip and perioral area has gained popularity as they provide important safety-related advantages compared to traditional hypodermic needles. This study was conducted to assess the safety and effectiveness associated with the use of a blunt-tipped microcannula for lip augmentation and correction of perioral rhytids using a small-particle, hyaluronic acid gel plus lidocaine (SPHAL). METHODS: A multi-center, op...

Commentary on: Efficacy of Retrobulbar Hyaluronidase Injection for Vision Loss Resulting from Hyaluronic Acid Filler Embolization.

Degradation of Hylauronic Acid Fillers Using Hyaluronidase in an In Vivo Model.

Soft tissue fillers manufactured with hyaluronic acid (HA) dominate the filler market around the world and the fact that HA can be dissolved using hyaluronidase contributes to its popularity. Degradation of cross-linked HA products can be performed in situ and access to hyaluronidase is therefore essential for health care professionals (HCP) to perform safe filler treatments. The aim of the present study was to develop an in vivo model where hyaluronidase degradation of HA fillers can be studied in a standa...

Combined use of microfocused ultrasound and a calcium hydroxylapatite dermal filler for treating atrophic acne scars: A pilot study.

An unfortunate consequence of severe acne is scarring, which can have serious psychosocial consequences. Available methods for treating acne scars have varying degrees of effectiveness.

Orbital and Ocular Ischemic Syndrome With Blindness After Facial Filler Injection.

The authors herein describe a case of orbital and ocular ischemic syndrome with blindness after cosmetic hyaluronic acid filler injection. Orbital function, but not visual function, returned after treatment with orbital hyaluronidase and corticosteroids.

Anomalous Behavior of Hyaluronan Crosslinking Due to the Presence of Excess Phospholipids in the Articular Cartilage System of Osteoarthritis.

Lubrication of articular cartilage is a complex multiscale phenomenon in synovial joint organ systems. In these systems, synovial fluid properties result from synergistic interactions between a variety of molecular constituent. Two molecular classes in particular are of importance in understanding lubrication mechanisms: hyaluronic acid and phospholipids. The purpose of this study is to evaluate interactions between hyaluronic acid and phospholipids at various functionality levels during normal and patholog...

The Role of Anastomotic Vessels in Controlling Tissue Viability and Defining Tissue Necrosis with Special Reference to Complications Following Injection of Hyaluronic Acid Fillers.

Most target areas for facial volumization procedures relate to the anatomical location of the facial or ophthalmic artery. Occasionally, inadvertent injection of hyaluronic acid (HA) filler into the arterial circulation occurs, and unrecognised, is irreparably associated with disastrous vascular complications.Of note, the site of complications, irrespective of the injection site, is similar, and falls into only 5 areas of the face, all within the functional angiosome of the facial or ophthalmic artery.

Dermal Filler Presenting as Lobular Radiopacities in an Edentulous Patient: A Clinical Report.

This clinical report describes the unusual appearance of radiopacities, lobular in nature, observed on a dental panoramic image of an edentulous patient. Upon questioning, the patient described a history of recently having hydroxylapatite-based dermal filler placed in her right and left cheeks to reduce wrinkles and enhance cosmetic appearance. The localization and shape of the radiopacities were consistent with the placement of the dermal filler.

Hyaluronic acid in dermatomyositis and polymyositis: relationship with disease and cutaneous lesions.

There are scarce studies in the literature about hyaluronic acid in systemic autoimmune myopathies.

Non-responsive breast cellulitis after hyaluronic acid filler injection.

Coefficient of Friction Between Carboxymethylated Hyaluronic Acid-Based Polymer Films and the Ocular Surface.

Hyaluronic acid-based polymer films are emerging as drug-delivery vehicles for local and continuous drug administration to the eye. The highly lubricating hyaluronic acid increases comfort, but displaces films from the eye, reducing drug exposure and efficacy. Previous studies have shown that careful control of the surface interaction of the film with the eye is critical for improved retention.

Fibroblast populated collagen lattices exhibit opposite biophysical conditions by fibrin or hyaluronic acid supplementation.

Fibrin and hyaluronic acid are important components of the provisional wound matrix. Through interactions with fibroblasts, they provide biophysical cues that regulate the viscoelastic properties of the extracellular matrix. To understand the roles of fibrin and hyaluronic acid in a collagenous environment, we used fibroblast populated collagen lattices (collagen, collagen-fibrin, and collagen-hyaluronic acid). Compared with collagen and collagen-hyaluronic acid cultures, collagen-fibrin cultures showed les...

Intra-Arterial Thrombolytic Therapy Is Not a Therapeutic Option for Filler-Related Central Retinal Artery Occlusion.

Cosmetic facial filler-related central retinal artery occlusion (CRAO) is a devastating complication of facial hyaluronic acid (HA) injection and can be managed by intra-arterial thrombolytic therapy (IATT). The authors report on a 20-year-old woman who developed unilateral CRAO due to facial HA injection and who, despite prompt IATT, lost vision. A review of the related literature found 14 other female patients who developed cosmetic facial filler-related CRAO and accepted IATT management. In no case was v...

A Randomized Study to Assess the Efficacy of Skin Rejuvenation Therapy in Combination With Neurotoxin and Full Facial Filler Treatments.

Hyaluronan in adipogenesis, adipose tissue physiology and systemic metabolism.

Hyaluronic acid (HA, also known as hyaluronan), is a non-sulfated linear glycosaminoglycan polymer consisting of repeating disaccharide units of d-glucuronic acid and N-acetyl-d-glucosamine abundantly present in the extracellular matrix. The sizes of hyaluronic acid polymers range from 5000 to 20,000,000 Da in vivo, and the functions of HA are largely dictated by its size. Due to its high biocompatibility, HA has been commonly used as soft tissue filler as well as a major component of biomaterial scaffold...

Effect of mechanical stress on the Raman and infrared bands of hydroxylapatite: A quantum mechanical first principle investigation.

The calcium apatite minerals are among the most studied in the biomaterial field because of their similarity with the mineral phase of bone tissues, which is mainly the hexagonal polymorph of hydroxylapatite. Given the growing interest both in the microscopic processes governing the behaviour of these natural biomaterials and in recent experimental methods to investigate the Raman response of hydroxylapatite upon mechanical loading, we report in the present work a detailed quantum mechanical analysis by DFT...

Protective Therapeutic Effects of Peptide Nanofiber and Hyaluronic Acid Hybrid Membrane in in vivo Osteoarthritis Model.

Osteoarthritis (OA) is a condition where tissue function is lost through a combination of secondary inflammation and deterioration in articular cartilage. One of the most common causes of OA is age-related tissue impairment because of wear and tear due to mechanical erosion. Hyaluronic acid-based viscoelastic supplements have been widely used for the treatment of knee injuries. However, the current formulations of hyaluronic acid are unable to provide efficient healing and recovery. Here, a nanofiber-hyalur...
