The use of acellular dermal matrices (ADM), sometimes referred to as extracellular matrix (ECM), has become an interesting aspect of breast reconstruction. A great deal of literature is available, totaling over 7000 ADM-based reconstructions. Most often, ADMs are used in a skin sparing mastectomy (SSM) scenario, although heterologous breast augmentation with a sub-pectoral fixation may also require an ADM application. Their use has become an attractive, but expensive option. Available data shows head to head comparisons between individual ADMs to be mostly retrospective in nature with only a few prospective trials available...

In modern implant-based immediate breast reconstruction, it has become common to use biological acellular dermal and synthetic matrices in combination with a tissue expander or an implant. The aim of this systematic review was to examine differences in recurrence of cancer, impact on oncological treatment, health related quality of life, complications and aesthetic outcome between matrix and no matrix in immediate breast reconstruction. Systematic searches, data extraction and assessment of methodological quality were performed according to predetermined criteria...

Acute and chronic wounds contribute to increased morbidity and mortality in affected people and impose significant financial burdens on healthcare systems. For these challenging wounds, Acellular Dermal Matrices (ADMs) have been used as a biological wound coverage. Unlike engineered dermal matrices, ADMs are prepared through the removal of cells from skin, while preserving the extracellular matrix structure and function. In this study, our primary objective was to develop a detergent-free method of decellularization of the skin to mitigate chemical stress on matrix molecules...

Various methods are available for vaginoplasty, but many of them have the drawbacks including surgical complexity and postoperative pain at the donor site. We herein evaluated the outcomes of vaginoplasty using tissue-engineered biomaterial graft. This study included 16 early stage cervical cancer patients who received curative surgery in combination with radiotherapy. They underwent vaginoplasty with tissue-engineered biological material, acellular dermal matrix (ADM). After treatment, a vaginal dilator was advised to be used for 6 months to prevent contraction of vagina...

INTRODUCTION: The introduction of acellular dermal matrices (ADMs) contributed to the growing diffusion of direct-to-implant breast reconstruction (DTI-BR) following mastectomy for breast cancer. According to specific legislations, European specialists could not benefit from the use of human-derived ADMs, even though most evidence in the literature are available for this kind of device, showed optimal outcomes in breast reconstruction. The Skin Bank of the Bufalini Hospital (Cesena, Italy) obtained in 2009 the approval for the production and distribution of a new human cadaver-donor-derived ADM (named with the Italian acronym, MODA, for matrice omologa dermica acellulata) from the Italian National Transplant Center and National Health Institute...

Background: The last two decades have seen significant changes in surgical management of breast cancer. The offer of immediate breast reconstruction (IBR) following mastectomy is currently standard practice. Skin sparing and nipple sparing mastectomy with implant-based IBR have emerged as oncologically safe treatment options. Prepectoral implant placement and complete coverage of implant with acellular dermal matrix (ADM) eliminates the need to detach the muscle from underlying chest wall in contrast to the subpectoral technique...

BACKGROUND: Acellular dermal matrices can be combined with implant-based breast reconstruction to help optimize outcomes. SurgiMend PRS is a fetal bovine dermis-derived acellular dermal matrix composed of type I collagen and approximately 30 percent type III collagen, sharing many of the properties of human cadaveric acellular dermal matrix. METHODS: This was a retrospective, single-center analysis of 111 adult patients (147 breasts) undergoing one-stage (83.7 percent) or two-stage (16...

There is no report to investigate the histology and biomechanical strength of remodeled tendon-to-bone junction more than 6 months after patch grafting with acellular dermal matrix (ADM) on rotator cuff defect. We investigated those 12 months after surgery and hypothesized that a new native enthesis is not regenerated and the biomechanical strength is inferior to normal control. Adult male Sprague-Dawley rats underwent ADM patch grafting for the rotator cuff defect. Quantitative histological analysis, immunohistochemical analysis for collagen type I and III, and biomechanical testing were performed 12 months after surgery...

BACKGROUND: The breast reconstructive subpectoral technique commonly leads to functional consequences. Recently, a new conservative prepectoral breast reconstruction (PPBR) technique was proposed and its surgical safety and aesthetic effectiveness proved. The aim of this prospective nonrandomized study was to compare the functional and economical outcomes of the PPBR procedure versus the subpectoral one. PATIENTS AND METHODS: From February 2015 to September 2016, 86 patients underwent mastectomy with immediate implant-based reconstruction...

BACKGROUND: While DBS is a relatively safe procedure, skin erosion is a commonly reported hardware complication that can threaten the DBS system. Patients with PD are especially at risk for this complication due to their autonomic dysregulation and impaired nutrition. Early detection of impending skin erosion allows for intervention that may prevent hardware destruction. Here we report a novel technique to address this complication preemptively. We describe the use of an acellular dermal matrix to prevent skin erosion in 20 patients with PD who were treated with DBS and showed signs of impending skin erosion...

INTRODUCTION: Synthetic materials have traditionally been used for tissue reconstruction in thoracic surgery. New biomaterials have been tested in other areas of surgery with good results. Non-cross-linked swine dermal collagen prosthesis has been used to reconstruct musculofascial defects in the trunk with low infection and herniation rate. MATERIAL AND METHODS: Retrospectively, we analyze our initial experience of chest wall reconstruction on large defects using a non-cross-linked swine dermal collagen matrix mesh with a thickness of 1...

Acellular dermal matrix (ADM) materials are used as scaffold materials in reconstructive surgery. The internal structural response of these materials in load-bearing clinical applications is not well understood. Bovine ADM is characterized by small-angle X-ray scattering while subjected to strain. Changes in collagen fibril orientation (O), degree of orientation as an orientation index (OI) (measured both edge-on and flat-on to the ADM), extension (from d-spacing changes) and changes to intermolecular spacing are measured as a result of the strain and stress in conjunction with mechanical measurements...

The aim of this pilot project was to introduce a novel use of acellular dermal matrix (ADM) in combination with infrapatellar fat pad mesenchymal stromal cells (IPFP-MSCs) to effect repair in a rabbit osteochondral defect model. ADM, in a range of surgical procedures, has been shown to promote remodelling of tissue at the site of implantation. Rabbit-derived ADM (rabADM) was prepared from the skin of donor rabbits. Autologous IPFP-MSCs were obtained at the time of knee surgery. Osteochondral defects (4mm cartilage outer/2mm central bone defect) were drilled into distal femoral condyles of 12 New Zealand White rabbits...

The reverse sural adipofascial flap (RSAF) is used to reconstruct challenging wounds of the foot and ankle. It offers several advantages over the traditional reverse sural flap, including less venous congestion. To complete the reconstruction, split-thickness skin grafting (STSG) may be done immediately or in a delayed fashion; however, both scenarios result in suboptimal take rates and prolonged healing. An acellular dermal matrix (ADM; Integra; Ethicon Inc, Somerville, New Jersey) and negative-pressure wound therapy (NPWT) combined with RSAF followed by delayed STSG may decrease wound healing time...

PURPOSE: A growing trend in breast reconstruction has been placement of tissue expanders in the pre pectoral space. This is a change from the practice of placement under the pectoralis major with or without an acellular dermal matrix (ADM) sling. The move toward pre pectoral placement with an ADM wrap has the intent of decreasing post-operative pain and decreasing animation deformities. The cosmesis of pre pectoral reconstructions in the setting of post mastectomy radiation has also appeared improved in our early experience, when compared to submuscular reconstructions...

Breast cancer is one of the most deadly tumors in women, and new procedures for post- surgical breast reconstruction have been developed which includes autologous stromal vascular fraction (SVF), platelet-derived growth factors, biomaterials and various stem cells. Adipose derived-stem cells (ASCs) has been reported to be one of the most widely used stem cell for breast reconstruction because of their ability to form new functional adipose tissue and vessels and in combination with stromal vascular fraction has been also reported efficient for breast reconstruction...
