Background: 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. Objectives: To highlight the importance of the patient's history of previous cosmetic procedures including rhinoplasty in the emergence of vascular complications...

Macroscopic hydrogels are commonly used as injectable scaffolds or fillers, however they may easily obstruct blood vessels, which poses risks and limits their clinical use. In the present study, three types of hyaluronic acid (HA)-based hydrogel micro-particles with non-covalent, covalent semi-interpenetrating and conventional 3D molecular networks, have been designed, fabricated and characterized. The micro-particles are spherical, biconcave or irregular in shape and their diameter ranged between 2.5 and 3...

Background: Nonsurgical aesthetic treatments are usually preferred by patients because their effects are visible immediately after the treatment and patients can return to their normal activities on the same day. Although many studies have indicated safety and efficacy of filler injection to improve facial appearance, it is not absolutely confirmed for nose reshaping. Objectives: To assess the safety and early satisfaction of 52 consecutive patients underwent nonsurgical rhinoplasty with an injection of a 20-mg/mL smooth, cohesive, and viscous hyaluronic acid (HA) filler...

Neauvia Intense is biocompatible, injectable hyaluronic acid (HA) filler PEG cross-linked for facial soft-tissue augmentation that provides volume to tissues. The aim of the present study is to evaluate the sensitivity of Neauvia Intense in hyaluronidase from bovine testes in a time-course analysis. The test is based on the colourimetric determination of the N-acetyl - D - glucosamine (NAG) released by the hyaluronidase in standardised conditions. The in vitro conditions involve the treatment of Neauvia Intense with a known concentration of the enzyme (6080U/ml)...

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 scaffolds in tissue engineering...

Hyaluronic acid fillers have been increasingly popular for soft tissue augmentation. Although generally considered safe, early and delayed types of adverse events were reported. We describe an unusual delayed type reaction observed with hyaluronic acid filler in a series of three patients treated for tear trough and periorbital hollow. Patients presented with a unilateral lower eyelid swelling without palpable nodules or tenderness developing months after injection and disappearing in few days. Reaction was triggered by infection in two patients...

BACKGROUND: Cross-linked hyaluronic acid-based fillers have gained rapid acceptance for treating facial wrinkles, deep tissue folds and sunken areas due to aging. This study evaluates, in addition to space-filling properties, their effects on softness and elasticity as a secondary effect, following injection of 3 commercially available cross-linked hyaluronic acid-based fillers (15mg/mL, 17,5mg/mL and 20mg/mL) in patients presenting with congenital or acquired facial malformations. PATIENTS ET METHODS: We started injecting gels of cross-linked hyaluronic acid-based fillers in those cases in 2013; we performed 46 sessions of injections in 32 patients, aged from 13-32...

BACKGROUND/PURPOSE: Following intradermal injection, hyaluronic acid (HA)-based fillers tend to spread within the reticular dermis and to distribute between the dermal fibers. This biointegration is commonly measured qualitatively using histological methods. We developed a "toolbox" consisting of a visual scoring and a semi-automatic image analysis method using internal developed algorithm to quantitate the biointegration of Restylane® in histological sections. METHODS: Restylane® was injected intradermally in the abdominal skin of 10 healthy human subjects scheduled for abdominoplasty...

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 vision loss clinically improved...

Collagen soft tissue fillers suffer from fast reabsorption, which minimizes their use as a tissue engineered construct. Extensive cross-linking can be utilized to extend longevity, but changes in microstructure and biomechanics can have deleterious effects. To enhance longevity while still achieving a natural microstructure, gold nanoparticles (AuNPs) were conjugated to fibrilized collagen and homogenized into an injectable form for use as a soft tissue filler. A long-term animal study in Yucatan swine was conducted to assess biocompatibility and longevity...
