BACKGROUND To date, various types of acellular dermal matrix (ADM) have been developed for clinical use. AlloDerm is the most familiar type of ADM to most surgeons in breast reconstruction. It is prepared by freeze-drying. CG CryoDerm is the first form of ADM that requires no drying process. Therefore, theoretically, it has a higher degree of preservation of the dermal structures than AlloDerm....

BACKGROUND AlloDerm and DermaMatrix are 2 acellular dermal implants currently used by reconstructive surgeons at our institution for reconstruction of parotidectomy defects. We looked at the postoperative complication rates following subcutaneous implantation of these acellular dermal implants for parotid bed reconstruction. METHODS A retrospective analysis was conducted following approval by...

INTRODUCTION Synthetic mesh is the prosthetic material used for most inguinal hernioplasties. However, when left in contact with intra-abdominal viscera, it often becomes associated with infection and migration, particularly in irradiated tissues, contaminated fields, immunosuppressed individuals, and patients with intestinal obstruction or fistula. AlloDerm(®) Regenerative Tissue Matrix (LifeC...

INTRODUCTION To describe the underlay tympanoplasty technique using an acellular dermal graft(AlloDerm) for tympanic membrane (TM) reconstruction in a guinea pig model and to demonstrate the feasibility of the technique using AlloDerm tissue harvested from the prepuce as a source of tissue for future grafting in human TM reconstruction. MATERIALS AND METHODS The prepuce was divided during cir...

OBJECTIVE The role for acellular dermal matrix in implant-based breast reconstruction-providing coverage of the inferolateral border of the underlying prosthesis and allowing control over the inframammary fold-has become increasingly popular. Although AlloDerm (LifeCell, Branchburg, NJ) is free of cellular components responsible for the antigenic response, its processing does not guarantee ster...

The objective of this study was to assess the efficacy of the use of an ex vivo produced oral mucosa equivalent (EVPOME) for intraoral grafting procedures. Autogenous keratinocytes were harvested from a punch biopsy 4 weeks prior to surgery, placed in a serum-free culture system and seeded onto a human cadaveric dermal equivalent, AlloDerm. Thirty patients with either a premalignant or cancerou...

BACKGROUND The advantages of dual-plane, partially submuscular breast implants are well documented. Standard conversion techniques to dual-plane positioning use marionette sutures and internal capsulorrhaphy sutures from the lower edge of the pectoralis major muscle to the anterior capsule or breast fascia within the subglandular plane. These techniques are limited by high rates of postoperativ...

METHODS: IRB approved retrospective review was conducted to identify consecutive implant-based reconstruction procedures performed at a tertiary academic medical institution by a single plastic surgeon over 15 years. Clinical endpoints of infection, seroma, hematoma, delayed wound healing, and explantation were recorded. Univariate analysis was conducted to compare patient characteristics acros...

BACKGROUND The use of acellular dermal matrix has facilitated immediate prosthesis-based breast reconstruction. However, few studies directly compare surgical outcomes following acellular dermal matrix-based reconstruction with two of the most commonly available materials, AlloDerm and FlexHD. Those studies that are available often do not adequately control for the surgeon as a variable. The au...

Macrophages have recently been characterized as having an M1 or M2 phenotype based on receptor expression, mechanism of activation and function. The effects of macrophage phenotype upon tissue remodeling following implantation of an acellular dermal matrix (ADM) is largely unknown. The purpose of this study was to compare the macrophage phenotype and tissue remodeling elicited by four different...
