The purpose of this article is to describe reconstruction of the maxillary alveolar ridge by use of a microvascular free flap combined with an immediate tissue-engineered bone graft. This novel surgical technique involved the use of a radial forearm free flap and immediate allogeneic avascular bone graft augmented with bone morphogenetic protein and bone marrow aspirate concentrate. A poly-d,l-lactic acid mesh was used a containment unit for the bone graft. The patient was successfully treated with a viable radial forearm free flap for soft tissue and regeneration of bone with adequate height and width, which allowed the placement of 3 dental implants with excellent arch coordination...

When lesions in soft tissue reach the gingival margin, they can produce aesthetic defects during its permanence and after its removal. Periodontal plastic surgery allows the correction of the gingival contour using different techniques. This paper is a case report of a peripheral ossifying fibroma removal in the interproximal area of teeth 21 and 22 in addition to root coverage of the affected area through two surgical phases: keratinized gingival tissue augmentation surgery with free gingival graft concurrent with removal of the lesion and, in a second stage, root coverage by performing coronally advanced flap technique with a follow-up of five years...

Knowledge of thermal history and/or distribution in biological tissues during laser based hyperthermia is essential to achieve necrosis of tumour/carcinoma cells. A semi-analytical model to predict sub-surface thermal distribution in translucent, soft, tissue mimics has been proposed. The model can accurately predict the spatio-temporal temperature variations along depth and the anomalous thermal behaviour in such media, viz. occurrence of sub-surface temperature peaks. Based on optical and thermal properties, the augmented temperature and shift of the peak positions in case of gold nanostructure mediated tissue phantom hyperthermia can be predicted...

Expanded polytetrafluoroethylene (ePTFE) has been extensively used for facial soft tissue augmentation procedures, and is regarded as safe and reliable and suitable as a permanent implant. This implant is generally used in the lower third of the face for lips filling, nasal augmentation, nasolabial folds and chin augmentation, and rarely for congenital or acquired depressed deformities of the face. The aim of the present study was to assess the effects of ePTFE in congenital or acquired depressed deformities of the face...

The patients with secondary bilateral cleft lip and nasal deformity always suffer from a serious part of the horizontal and vertical soft tissue deficiencies in the upper lip and nose, especially the columella. Normally, the Abbe flap is used to increase the soft tissue volume of upper lip. However, how to reconstruct the sever columella deficient, how to make full use of the Abbe flap and the remaining soft tissue of the upper lip, are always the problems that need to be solved by plastic surgeons. Twenty-nine patients with secondary bilateral cleft lip and severe columella deficiency were simultaneously reconstructed with several local flaps like dominos that was called "Domino sliding flaps...

Eric W Tan, Lew C Schon
Improving the quality and strength of soft tissue repairs remains an important area of orthopedic research and innovation. The need for immobilization and early motion is an important balance essential for the successful treatment of tendon repair and reconstruction. Mesenchymal stem cell (MSC)-bearing sutures represent an emerging biological augmentation to traditional suture repair. Two previous large studies using stem cell sutures in rat Achilles tendon models have demonstrated early increased biomechanical strength and significantly increased ultimate failure strength...

Porous silk protein scaffolds are designed to display shape memory characteristics and volumetric recovery following compression. Two strategies are utilized to realize shape recovery: addition of hygroscopic plasticizers like glycerol, and tyrosine modifications with hydrophilic sulfonic acid chemistries. Silk sponges are evaluated for recovery following 80% compressive strain, total porosity, pore size distribution, secondary structure development, in vivo volume retention, cell infiltration, and inflammatory responses...

Introduction: Autologous fat transfer has recently become an increasingly popular surgical procedure and comprises harvesting, processing and transplantation of adipose tissue, as well as professional follow-up care. This method, as a surgical procedure, can be utilised for trauma-, disease- or age-related soft tissue volume deficits and soft tissue augmentation. As usage is increasing, but the variables of fat harvest, specific indications and fashion of fat transfer are poorly defined, there is a great demand for development of a guideline in the field of reconstructive and aesthetic surgery...

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.

BACKGROUND: Alloplastic materials are a mainstay in Asian rhinoplasty. However, the outline of alloplastic implants can become conspicuous over time in rhinoplasty patients, which is a significant cause for revision. In revision rhinoplasty, alloplastic materials can remain a viable and affordable option in Asian patients. The acellular dermal matrices (ADM) are often used to interface between the silicone material and the skin envelope. This study assesses histologic changes following implantation of ADM-covered silicone material in rats...
