Introduction Hyaluronic acid based (HA) fillers are used for various cosmetic procedures. However, due to filler migration and degradation, reinjections of the fillers are often required. Methacrylated HA (MA-HA) can be made into injectable, shape-memorizing fillers (3D MA-HA) aimed to address this issue. In this study shape retention, firmness and biocompatibility of 3D MA-HA injected subcutaneously in mice were evaluated. Methods Fifteen mice, each receiving two subcutaneous injections in their back, were divided into 4 groups receiving HA, MA-HA, 3D MA-HA or saline, respectively...

Volume augmentation of the buttocks with injectable soft-tissue fillers is a cosmetic procedure; delayed adverse effects include the formation of granulomatous inflammatory nodules. We describe a 35-year-old woman with early-stage Hodgkin's lymphoma with multiple nodular subcutaneous densities on CT scans in both gluteal regions. These were the result of frequent injections with human collagen.

Traumatic soft tissue wounds present a significant reconstructive challenge. The adoption of closed circuit negative pressure wound therapy (NPWT) has enabled surgeons to temporize these wounds prior to reconstruction. Such systems use porous synthetic foam scaffolds as wound fillers at the interface between the negative pressure system and the wound bed. The idea of using a bespoke porous biomaterial that enhances wound healing as a filler for a NPWT system is attractive as it circumvents concerns regarding reconstructive delay and the need for dressing changes that are features of the current systems...

INTRODUCTION: Some studies have demonstrated that platelet rich fibrin (PRF) is a healing biomaterial with a great potential for bone and soft tissue regeneration, without any inflammatory reactions and may be used alone or in combination with bone grafts, promoting hemostasis, bone growth, and maturation. PRF appears as a natural and satisfactory aid in bone regenerative surgery in elderly patients with favorable results and low risks. AIM: This study wants to demonstrate how PRF in association with a new split crest augmentation technique can be a great aid in implant rehabilitation, especially in the elderly patients, when bone regeneration is required...

Volume loss due to facial aging can be restored by facial volumization using a variety of materials. Volumization can be performed in isolation or concurrent with other facial rejuvenation procedures to obtain an optimal aesthetic result. There is a myriad of manufactured products available for volumization. The use of autologous fat as facial filler has been adopted more recently and possesses certain advantages; however, the ideal filler is still lacking. Tissue engineering may offer a solution. This technology would provide autologous soft-tissue components for use in facial volumization...

The aging process results in volumetric changes on multiple levels of the face including the skin, soft tissue, and underlying facial skeleton. Malar and mandibular augmentation with facial fillers and alloplastic implants are two treatment options used to achieve the goal of volume enhancement. Noninvasive modalities have become increasingly popular due to the availability of office-based options that require a limited understanding of facial aesthetics, a basic grasp of the mechanisms behind the aging process, and no level of surgical expertise or training...

Proper functioning wound healing strategies are sparse. Adequate vascular formation to the injured area, as well as replacement of the volume loss, is fundamental in soft tissue repair. Tissue engineering strategies have been proposed for the treatment of these injury sites. Novel cell-free substance, human adipose tissue extract (ATE), has been previously shown to induce in vitro angiogenesis and adipogenesis and in vivo soft tissue formation. This study reports the translation of ATE preparation from laboratory to the operating room (OR)...

Botulinum toxin A and soft tissue fillers are cornerstones of facial rejuvenation procedures. They can also be of benefit in facial rehabilitation. We report on three female patients who were treated with botulinum toxin A and/or hyaluronic acid-based fillers, one after orthognathic surgery, two after Bell's palsy, to correct facial asymmetries and loss of volume to restore facial attractiveness and improve their self-esteem and quality of life. These minimally invasive procedures are safe and effective. However, they need to be repeated for the long-term rehabilitation...

BACKGROUND: Bellafill® is a soft tissue dermal filler composed of non-resorbable polymethylmethacrylate (PMMA) microspheres, suspended in a water-based carrier gel composed of 3.5% bovine collagen. It has been approved by the FDA for the correction of nasolabial folds and atrophic facial acne scars. Energy-based therapies are used for facial rejuvenation and treatment of acne scarring. However, little has been published about the effects of energy devices on previously placed PMMA. This prospective, in vivo clinical study evaluated the safety and histopathological effects of a number of different laser, light, and ultrasound treatment modalities on PMMA-collagen filler previously injected into human tissue...

Soft tissue augmentation products (or fillers) are used for the correction of age-related changes in areas of the face. The most common filler material is hyaluronic acid, which is synthetically cross-linked. These materials are generally safe, but some side effects do occur. New fillers are expected to be approved in the United States in the near future. Semin Cutan Med Surg 35(supp6):S117-119.

BACKGROUND: Nonresorbable substances are still injected to enhance soft-tissue volumes and fill subcutaneous defects. Inflammatory reactions (often termed granulomas) to these materials can be functionally and socially disabling. Most therapeutic options used until now are nonspecific antiinflammatory treatments, targeting an ill-defined immune reaction of undefined cause. The minimally invasive intralesional laser treatment can remove the foreign substance and the inflammatory reaction with an 808-nm diode laser...
