Saline Breast Implant

By Mayo Clinic Staff

Following a mastectomy, the plastic surgeon begins the reconstruction process by placing a tissue expander beneath the muscles of the chest wall. The patient then receives a series of injections of saline into the expander as an outpatient until the desired breast size is achieved. The expander is then removed and a permanent implant, either silicone or saline, is placed. This procedure can take up 1 year to complete.
