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.
Tissue expanders have silicone outer shells and either an internal valve or external port to allow for saline fluid injections. You will be offered a variety of shapes and sizes of tissue expanders if you choose breast implants as your breast reconstruction method. Your tissue expander should match the shape of the permanent breast implant that you are going to use. Both devices come in round, oval, and anatomical shapes.
