Was the nurse accurate about needing to know the technique used 25 years ago?

Inferiorly or superiorly nipple incision. Hello, I need to have another breast lift with implant exchange after initial 25 yrs ago. No records are available due to the time. The surgeon is on vaca for two weeks and possibly may not remember what technique he used. I was told by a nurse yesterday, that I need to know if the nipple was done inferior or superior so that I do not have nipple loss. He needs to know the technique. One of theirs did have loss and I’m in the same situation maybe… how risky is this? Thank you.
