Summary of "The use of porcine acellular dermal matrix in silicone implant-based breast reconstruction."


INTRODUCTION:
The most frequently occurring long-term complication in implant-based breast reconstruction is fibrotic capsule formation at the recipient site, with concurrent dysesthesia and poor aesthetic results. Using porcine acellular dermal matrix (PADM) as a connective tissue graft material is supposed to improve the quality and quantity of soft tissue in implant-based breast reconstruction. This study investigates the indications for and the results and the costs of using PADM for the correction or prevention of implant-associated breast deformities. MATERIALS AND
METHODS:
This study reviewed a single surgeon's experience in the correction or prevention of implant-associated breast deformities with PADM in breast cancer-related breast reconstruction from 2009 to 2011. A total of 23 patients (27 breasts) were included in the study. The aesthetic outcome, the incidence and the type of complication were analysed. Twenty-three women underwent breast cancer-related breast reconstruction: 19 women underwent single-breast reconstruction and four women underwent bilateral reconstruction.
RESULTS:
Of the 23 patients who underwent breast reconstruction, 18 (78%) were "satisfied" with the aesthetic and haptic outcome after implant-based reconstruction with PADM. One patient (one breast) required another breast operation because of ipsilateral breast cancer recurrence during the follow-up period. PADM-assisted implant-based breast reconstruction has a satisfactory safety profile.
CONCLUSION:
The use of PADM as an interface matrix for implant-based breast reconstruction yielded predictable and acceptable aesthetic and haptic results by preventing capsular contracture, rippling, implant malposition, soft-tissue thinning and failure of the silicone implant-based breast augmentation.

Medical and Biotech [MESH] Definitions

Implants used to reconstruct and/or cosmetically enhance the female breast. They have an outer shell or envelope of silicone elastomer and are filled with either saline or silicone gel. The outer shell may be either smooth or textured.

Synthetic organosiloxane gels that are formed from synthetic polymers of silicone oxide with organic sidechains (polydimethylsiloxane) by lengthening the polymer chains. Unlike silicone elastomers, they are not treated with amorphous silica. They are used as fillers in breast implants.

A secreted matrix metalloproteinase that is believed to play a role in EXTRACELLULAR MATRIX remodeling and cell fate determination during normal and pathological processes. Matrix metalloproteinase 11 was originally isolated in primary BREAST NEOPLASMS and may be involved in the process of tumorigenesis.

Synthetic material used for the treatment of burns and other conditions involving large-scale loss of skin. It often consists of an outer (epidermal) layer of silicone and an inner (dermal) layer of collagen and chondroitin 6-sulfate. The dermal layer elicits new growth and vascular invasion and the outer layer is later removed and replaced by a graft.

Surgical insertion of an inert sac filled with silicone or other material to augment the female form cosmetically.
