This retrospective study utilizes 3D imaging and mammometrics to compare implant-based breast reconstruction with and without the use of ADM. Previous studies have suggested improved aesthetic outcomes with the use of ADM, but none have been able to quantify this difference. Images were obtained at early and late time points following the expander-implant exchange procedure. Measurements included the point of maximum projection, the superior, inferior, medial and lateral volumetric distribution, and the distance from the point of maximum projection to the inframammary fold along the breast meridian...

Frey's syndrome and infra-auricular depressed deformities are the ones of the most common complications that can occur after total parotidectomy. We report 1 case of pleomorphic adenoma occurred in the deep lobe that obtained good results from using acellular dermal matrix (ADM) after total parotidectomy. A 24-year-old man visited the hospital with oval shape mass in right mandibular angle which of 4 cm in size was found in the deep lobe of right parotid gland from Magnetic resonance imaging scanning and a pleomorphic adenoma was suspected...

Anal fistula (AF) is a pathological connection between anus and skin in its surroundings. The main reason for the formation of anal fistula is a bacterial infection of the glands within the anal crypts. One of the modern techniques for the treatment of fistulas that do not interfere with the sphincters consists in implantation of a plug made from collagen material. We are presenting the first Polish experience with a new model of biomaterial plug for the treatment of anal fistula. We also point out key elements of the procedure (both preoperative and intraoperative) associated with this method...

We report a 7-year-old girl with xeroderma pigmentosum (XP), who presented in our clinic with a large melanoma (35 × 50 × 20 mm, Breslow depth 18 mm) in the zygomatic-malar area. Palliative surgery was performed to maintain her residual vision and to reduce the pain caused by the compression of local structures. Because of the limited access of autologous skin grafts in pediatric patients with XP who are severely affected, we opted to use an acellular dermal matrix. There was 100% graft uptake, and the pain due to compression by the tumor was alleviated...

The regional injection of connective tissue growth factor (CTGF) for diabetic wound healing requires multiple components and results in a substantial loss of its biological activity. Acellular dermal matrix (ADM) scaffolds are optimal candidates for delivering these factors to local ischemic environments. In this study, we explored whether CTGF loaded on ADM scaffolds can enhance fibronectin (FN) expression to accelerate diabetic wound healing via the Protein kinase C (PKC) signaling pathway. The performance of CTGF and CTGF+PKC inhibitor, which were loaded on ADM scaffolds to treat dorsal skin wounds in streptozotocin (STZ)-induced diabetic mice, were evaluated with naked ADM as a control...

Nipple reconstructions are prone to a variable and unpredictable degree of flattening, which in some cases lead to secondary reconstruction. The use of an acellular dermal matrix (ADM) augmentation may be appropriate in cases with very thin dermis that are particularly prone to flattening or in revision cases where the first procedure has already failed. The authors present a series of 13 nipple reconstructions in ten cases. Average projection at 12 months was 51% in primary cases and 46% in secondary revision cases...

Cell-based therapies have recently been the focus of much research to enhance skin wound healing. An important challenge will be to develop vehicles for cell delivery that promote survival and uniform distribution of cells across the wound bed. These systems should be stiff enough to facilitate handling, whilst soft enough to limit damage to newly synthesized wound tissue and minimize patient discomfort. Herein, we developed several novel modifiable nanofibre scaffolds comprised of Poly (ε-caprolactone) (PCL) and gelatin (GE)...

The selection of materials for orbital wall reconstruction has been a matter of debate. This study aimed to evaluate the effectiveness of an acellular allogenic dermal matrix (ADM) as an orbital wall reconstruction material and to compare the results of orbital wall reconstruction with the ADM to those of reconstruction with the more widely used absorbable mesh plate and porous polyethylene. We retrospectively reviewed the clinical charts and computed tomography images of 73 patients who underwent orbital reconstruction at 1 institution between March 2013 and February 2014...

This study evaluates a novel limited submuscular direct-to-implant technique utilizing AlloMax where only the upper few centimeters of the implant is covered by the pectoralis, whereas the majority of the implant including the middle and lower poles are covered by acellular dermal matrix. METHODS: The pectoralis muscle is released off its inferior and inferior-medial origins and allowed to retract superiorly. Two sheets of AlloMax (6 × 16 cm) are sutured together and secured to the inframammary fold, serratus fascia, and the superiorly retracted pectoralis...

Despite increasing interest in prepectoral implant-based reconstruction to avoid animation deformity (AD), the prevalence of this deformity and patient attitudes toward it have not been extensively studied. The purpose of this study was to report on AD in the breast reconstruction population and identify those at highest risk. METHODS: A retrospective chart review was completed for patients at least 6 months postoperative from subpectoral, implant-based breast reconstruction using acellular dermal matrix in the lower pole...

Immediate breast reconstruction is an acceptable treatment option after mastectomy for prophylaxis of early breast cancer. Different options exist for implant placement, incision technique, patient suitability, and institutional experience. This article is a case series exploring the feasibility and outcomes of patients undergoing immediate breast reconstruction using skin-sparing mastectomy without mesh or acellular dermal matrix (ADM) and with a vertical inframammary incision. METHODS: A single-institution retrospective analysis was performed for all patients who underwent immediate single-stage reconstruction with subcutaneous silicon implants without ADM between 2009 and 2014 inclusive...

Patients with displaced patellar fractures typically present with disruption to the extensor mechanism requiring acute surgical intervention. Chronic patellar fractures with disruption of the extensor mechanism are uncommon, and few surgical options are available. The authors present a patient who sustained a fracture to the inferior pole of the patella in Africa 5 years prior that was managed conservatively with bands and a brace. He decided to pursue surgical intervention because of difficulties with leg extension, weakness, and ambulation...

Acellular dermal matrix (ADM) is a tissue graft of allogeneic origin from post-mortem tissue donors prepared by an innovative decellularization process. The newly developed non-toxic and low cost decellularization process of cadaver origin dermis included ADM in breast reconstruction procedures proved to help coverage of the lower-pole of breast expanders or implants. As the results have shown, it did help to eliminate autologous dermis donor site morbidity along with shortening the operation time by avoiding elevation of additional muscle or fascia during the operation...

INTRODUCTION: Acellular dermal matrix (ADM) has gained widespread acceptance in immediate expander/implant reconstruction due to perceived benefits, including improved expansion dynamics and superior aesthetic results. Although previous investigators have evaluated its risks, few studies have assessed the impact of ADM on other outcomes, including patient-reported measures. METHODS: The Mastectomy Reconstruction Outcomes Consortium (MROC) Study used a prospective cohort design to evaluate patients undergoing post-mastectomy reconstruction from 10 centers and 58 participating surgeons between 2012 and 2015...

Silk fibroin (SF) and fiber alignment were introduced into polycaprolactone (PCL)-based electrospun nanofibers as chemical and physical cues for tendon tissue engineering applications. The physicochemical properties of random PCL (RP) nanofibers, random PCL/SF (RPSF) nanofibers and aligned PCL/SF (APSF) nanofibers were characterized for fiber orientation and SF blending effects. An in vitro cell culture with rabbit dermal fibroblasts (RDFBs) on nanofibers indicated that SF promotes cell proliferation to a higher extent than fiber alignment...
