How often does nipple necrosis occur statistically? Anything that will help prevent it (other than avoiding nicotine & 2nd hand smoke- I don't smoke and am not around it). Is there more risk if its secondary lift with exchange to smaller implants and removal of permanent sutures? I want my benelli lift converted to formal lift w/ different surgeon but am very fearful of necrosis- should I stage my procedures? What does new doc need to know from old doc to keep me safe
