The doctor said: skin tethering is fixed with 1) disconnecting the scar tissue and 2) a fat graft. But in 70% of cases the fat is reabsorbed and the skin reconnects. I found: 1. Fat graft is ONLY needed when the surgeon removes too much tissue. (my problem is specifically tethering) 2. I heard nothing about skin reattaching. my question: 1: Is fat graft necessary? 2: is cutting the tethering adequate and reliable? Is there a chance of re-connection?
