Breast recon - fat grafting

Hi everyone I've just joined this forum and have followed this discussion on fat grafting with interest. Had a mastectomy 10 years ago with immediate reconstruction. Implants now need to come out and I'd prefer fat grafting. In Sydney and exploring surgeons who do this often and preferably operate in the public system or who are on the Bupa no gap or known gap. I'd appreciate hearing of any good news stories : who you used, results a couple if years down the track. I've heard fat can get reabsorbed back into the body ( up to 30%) so more than 1 op is necessary. Is it permanent? Are you happy with results?
