BACKGROUND: The use of acellular dermal matrices (ADMs) has become the standard of practice in many reconstructive and aesthetic surgical applications. Different methods used to prepare the allograft tissue for surgical use can alter the ADMs natural properties. Aseptic processing has been shown to retain the natural properties of ADMs more favorably than terminally sterilized ADMs. Terminal sterilization has been historically linked to alteration of biological materials. In vitro work was conducted to compare ADM processing methods...

BACKGROUND: Implant-based breast reconstruction with an acellular dermal matrix is one of the most common procedures performed by plastic surgeons. Although numerous matrices are available, there is little literature comparing them. This study compares the rates of complications between two commonly used products: AlloDerm (human cadaveric) and SurgiMend (fetal bovine) acellular dermal matrices. METHODS: A retrospective review of a single center's 6-year experience was performed for consecutive, immediate breast reconstructions with acellular dermal matrix from 2009 to 2014...

BACKGROUND: Current cost data on tissue expansion followed by exchange for permanent implant (TE/I) reconstruction lack a necessary assessment of the experience of a heterogenous breast cancer patient population and their multiple outcome pathways. We extend our previous analysis to that of direct hospital cost as bundling of payments is likely to follow the changing centralization of cancer care at the hospital level. METHODS: We performed a retrospective analysis (2003-2009) of TE/I reconstructions with or without an acellular dermal matrix (ADM), namely Alloderm RTM...

The objective of this study was to compare the 2 leading human acellular dermal matrices in breast reconstruction with implants. This retrospective study draws on the experience of 2 expert surgeons with a history of long-standing use of the Alloderm-RTU (LifeCell Corporation, Branchburg, NJ) product who switched to the DermACELL acellular dermal matrix (LifeNet Health, Virgina Beach, Va) product. The consecutive nature of these data over this change allowed comparison between the 2 products without the confounding effects of patient selection or change in technique...

Acellular dermal matrix (ADM) is commonly employed to create an inferior pocket for the tissue expander in two-stage breast reconstruction. The authors sought to determine whether placement of ADM during the first stage of reconstruction decreases the amount of capsule formation at implant exchange. Patients who underwent mastectomy and tissue expander reconstruction were included in this study. Two biopsies were obtained at the time of implant exchange, one from the pocket adjacent to the ADM and the other from the area adjacent to the pectoralis muscle...

INTRODUCTION: Postoperative infections are a major complication associated with tissue-expander-based breast reconstruction. The use of acellular dermal matrix (ADM) in this surgery has been identified as a potential reservoir of infection, prompting the development of sterile ADM. Although aseptic and sterile ADMs have been investigated, no study has focused on the occurrence and clinical outcome of bacterial colonization before implantation. METHODS: Samples of aseptic AlloDerm, sterile Ready-To-Use AlloDerm, and AlloMax were taken before implantation...

BACKGROUND: Titanium cranioplasty is commonly used for surgical closure of skull defects post craniectomy. Superficial implantation of the mesh can result in discomfort, palpability, and in extreme patients, exposure of the mesh. Exposed titanium mesh can be complicated by infections and often requires implant revision or removal. Generally, the contour of the titanium mesh is camouflaged in the hairline of the patient and any aesthetic complication can remain inconspicuous. However, in the frontal bone position the thin hairless forehead skin often may not easily hide the contour of the underlying titanium mesh...

OBJECTIVES: To evaluate the effectiveness of regenerative tissue matrix (Alloderm) as an oral layer for difficult anterior palatal fistula closure. MATERIALS AND METHODS: The authors have tested the feasibility of a novel surgical technique of adding a regenerative tissue matrix (Alloderm) as an oral layer for closure of recalcitrant large anterior palatal fistulae and report the outcome of the first 12 patients in this pilot study. Patients with recurrent large fistula who otherwise would require either a local pedicled flap, free flap, or an obturator were treated with this technique and followed up for at least 6 months to monitor the progress of healing...

Palatal fistula following cleft palate repair, is one of the considerable complications and remains a challenging problem to the surgeons. The reported recurrence rate of the fistula is between 33% to 37%. Due to fibrosis and poor vascularity of adjacent tissues, high recurrence rates are typical. Closure of palatal fistulas can be achieved by different surgical techniques like local, regional and distant flaps, local turnover flaps, pedicled flaps from oral mucosa, buccal fat pad flaps, inter-positional cartilage grafts can be utilized for management of small fistulas...

BACKGROUND: There has been an increasing role of acellular dermal matrices (ADMs) and synthetic meshes in both single- and two-stage implant/expander breast reconstruction. Numerous alloplastic adjuncts exist, and these vary in material type, processing, storage, surgical preparation, level of sterility, available sizes and cost. However, there is little published data on most, posing a significant challenge to the reconstructive surgeon trying to compare and select the most suitable product...

BACKGROUND: Acellular dermal matrices (ADMs) provide clinical benefits in breast reconstruction but have been associated with increased postoperative complications, most frequently seromas. Fenestration of the ADM before insertion into the reconstructed breast may reduce the incidence of postoperative complications. In this retrospective analysis, postoperative complications were assessed after breast reconstruction with or without fenestrated ADMs. METHODS: Patients who underwent immediate 2-staged implant breast reconstructions using ADM at a single center were assessed...

During the last two decades, acellular dermal matrices (ADM) have been more widely used in reconstructive procedures i.e. breast reconstructions. Several, both synthetic and biologic products derived from human, porcine and bovine tissue, have been introduced. Until this point postoperative complications for the acellular dermal matrices, as a group, have been the main focus. The purpose of this literature review is to summarize the current knowledge on the each biologic product used in breast reconstructions, including product specific complication frequencies...

Mucosal fenestrations are rarely encountered in clinical practice, and as such their management is not often reported. Their treatment might be further complicated due to a communication with the oral environment, making them more susceptible to accumulation of debris, plaque, and calculus, thereby reducing the probability of mucosal renewal. The aim of the present case report is to highlight one such rare clinical scenario and its apt and effective management. Surgical management of an uncommon presentation of concomitant gingival recession with an isolated mucosal fenestration in an atypical location, with an allograft matrix is presented here with 2 years' follow-up...

BACKGROUND: The presence of an adequate width of keratinized tissue is important to maintain a healthy dentogingival junction. In case of inadequate width of attached gingiva, the gingival augmentation procedure has been performed classically using the patient's own masticatory mucosa and more recently, using an acellular dermal allograft as the donor material. AIMS: The aim of the clinical study was to evaluate and compare the effectiveness of free gingival graft (FGG) and acellular dermal matrix (ADM) allograft in the ability to increase the zone of attached gingiva...
