Natural and synthetic fillers have revolutionized aesthetic facial rejuvenation and soft-tissue augmentation. We present a case highlighting the dangers of filler self-injection. A 37-year-old woman self-injected a dermal filler around both temples. She immediately experienced left--side hearing loss, blanching over the left face, and pain. Prompt treatment with hyaluronidase, topical nitro paste, and warm compresses ensued. An emergency computed tomography angiogram showed occlusion of a superficial temporal artery branch...

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...

Fillers are products that fill the space in soft tissues of the human body and actively used in the various medical fields. Unfortunately, most of the cost-effective commercially available fillers are synthetic and have limitations in terms of their biocompatibility. Here, we evaluated the possible application of decellularized xenogenic cartilage as a long-lasting material for soft tissue augmentation and compared it with two commercially available fillers Artesense (polymethylmethacrylate microspheres) and Radiesse (calcium hydroxyapatite [CaHa])...

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...

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...

BACKGROUND: The number of procedures involving dermal filler injection is still on the rise. Although their safety is improving, not all complications can be avoided. The late complications manifesting as nodules or granulomas pose a particular diagnostic and therapeutic challenge, due to the lack of uniform standards or guidelines. High-frequency, ultrasound imaging appears to be a useful method for distinguishing between granulomas and nodular dermal filler deposits. AIM: The aim of the paper was to evaluate the utility of high frequency ultrasound imaging for distinguishing between foreign body granulomas and nodular dermal filler deposits...

Soft-tissue filler (STF) injections have been used worldwide for cosmetic reasons. In most cases, they are not approved by the United States Food and Drug Administration (FDA). Regulatory boards in Latin American countries do not allow the medical use of STF injections; however, these injections are still widely used. A case of calcitriol-mediated hypercalcemia with ectopic calcifications, chronic kidney disease, nephrolithiasis and calcinosis is presented. The reported case highlights the consequences of STF use, including calcitriol-mediated hypercalcemia secondary to granulomatous reactions years after an esthetic procedure...

Foreign body granulomas can develop after the injection of various cosmetic filling materials into the facial area to flatten wrinkles. Clinically, reactive lesions are easily mistaken for soft-tissue neoplasms or cysts. This report presents a case of foreign body granuloma in a 52-year-old female patient complaining of a painless swelling in the nasolabial region. Both clinical and histological features are described, underscoring the diagnostic role of magnetic resonance imaging findings.

PURPOSE: Chronic infection (CO) and infected non-union of the long bones are relatively rare conditions in paediatric patients. Large bone defects secondary to these conditions can be managed with the induced membrane technique. The technique requires grafting of the bone void, although it is not yet established what bone substitute is the best option. The aim of this work was to evaluate the outcome and efficacy of treatment in children with CO and infected non-union of the long bones using the induced membrane technique and bone (BG) versus beta-tricalcium phosphate (BTP) grafting...
