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.
The expander is slowly filled with saline during visits to the doctor after surgery. In the second stage, after the chest tissue has relaxed and healed enough, the expander is removed and replaced with an implant. The chest tissue is usually ready for the implant 6 weeks to 6 months after mastectomy.Expanders can be placed as part of either immediate or delayed reconstructions (2). An optional third stage of breast reconstruction involves recreating a nipple on the reconstructed breast.he expander is slowly filled with saline during visits to the doctor after surgery.
