Research is looking at implant reconstruction with a tissue expander using a dermal matrix product to cover the implant compared to using skin and muscle to cover the implant. The dermal matrix essentially forms a âslingâ that helps form a pocket and support the lower portion of the implant, holding it in position.
This patient underwent bilateral nipple-sparing mastectomies and immediate breast reconstruction with tissue expanders and Alloderm. The second reconstructive stage (3 months later) involved exchange of the tissue expanders for silicone implants and fat grafting to achieve the most natural results.his patient underwent bilateral nipple-sparing mastectomies and immediate breast reconstruction with tissue expanders and Alloderm.
