Recent advantages in the anatomical understanding of the face have turned the focus toward the subcutaneous and deep facial fat compartments. During facial aging, these fat-filled compartments undergo substantial changes along with other structures in the face. Soft tissue filler and fat grafting are valid methods to fight the signs of facial aging, but little is known about their precise effect on the facial fat. This narrative review summarizes the current knowledge about the facial fat compartments in terms of anatomical location, histologic appearance, immune-histochemical characteristics, cellular interactions, and therapeutic options...

BACKGROUND: The nose is a dangerous site for filler injection. This study investigated the anatomy of the dorsal nasal artery at the upper part of the nose to clarify how ocular complications occur. METHODS: Dissections were performed in 50 noses of the embalmed cadavers. Either the soft embalming or formaldehyde embalming processes were used. RESULTS: The dorsal nasal artery is not a constant artery. The artery traveled in the subcutaneous tissue layer of the nasal dorsum on the transverse nasalis muscle and its midline nasal aponeurosis which connected the muscles on both sides...

: Soft tissue filler injections are the second most common non-surgical procedure performed by the plastic surgeon. Embolization of intravascular material after facial injection is a rare but terrifying outcome due to the high likelihood of long-term sequela such as blindness and cerebrovascular accident. The literature is replete with examples of permanent blindness caused by injection with autologous fat, soft tissue fillers such as hyaluronic acid, PLLA, calcium hydroxyl-apatite, and even corticosteroid suspensions...

With limited downtime and immediate results, facial filler injections are becoming an ever more popular alternative to surgical rejuvenation of the face. The results, and the complications, can be impressive. To maximize safety during injections, the authors have outlined general injection principles followed by pertinent anatomy within six different facial danger zones. Bearing in mind the depth and the location of the vasculature within each zone, practitioners can tailor their injection techniques to prevent vessel injury and avoid cannulation...

Injectable hydrogels and microspheres derived from natural polysaccharides have been extensively investigated as drug delivery systems and cell scaffolds. In this study, we report a preparation of covalent hydrogels basing polysaccharides via the Schiff' base reaction. Water soluble carboxymethyl chitosan (CMC) and oxidized chondroitin sulfate (OCS) were prepared for cross-linking of hydrogels. The mechanism of cross-linking is attributed to the Schiff' base reaction between amino and aldehyde groups of polysaccharides...

BACKGROUND: Soft-tissue fillers have become important products for facial rejuvenation. Deep fat compartments and facial bones lose volume during the natural aging process. For the most natural-looking results, deep volumetric injections at strategic sites are therefore preferred. Supraperiosteal placement is performed with a sharp needle or a non-traumatic cannula. OBJECTIVES: The primary objective was to determine whether there is a difference in precision between supraperiosteal placement with a sharp needle compared with a non-traumatic cannula in cadaver specimens...

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 before 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 filler for an 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)...
