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.
If you're having an implant or tissue expander inserted at the same time, this will take about another hour or so. If you're having implant surgery some time after mastectomy and other treatments (delayed reconstruction), surgery to insert the tissue expander may be done about 4 to 6 months after your last treatment.
