What can I do to prevent nipple necrosis after surgery?

I
do approximately 1 explantation with mastopexy per month and the technique I
use is The Bellesoma Method.  This will
reshape your breast tissue creating upper pole fullness without implants,
elevate them higher on the chest wall and more medial to increase your
cleavage.  Vertical scars are avoided,
nipple sensation and the ability to breast feed are maintained, if not injured
during your previous surgery.  After
implantation, the breast below the level of the nipple is stretched thin.  Vertical scar techniques cut through this
thin tissue and damages the circulation of the nipple.  You do not want to smoke or wear a
compressive garment, which will interfere with circulation.  Best Wishes,Gary Horndeski, M.D.

There is nothing you can do to PREVENT nipple necrosis.  It is a risk of surgery.  But you can improve your chances and lower the risk.  Do not smoke. Pick a very experienced surgeon after interviewing at least three.  Avoid combining an implant insertion at the same time as a mastopexy.  These operations are the enemy of each other, stretching and shrinking.  Make sure your surgeon places drains during surgery.  Do not combine multiple lengthy surgeries.  Keep total operative time under 4 hours. These precautions will lower the risk but not eliminate it.
We have not lost a nipple in 40 years following these rules, but maybe we are just lucky?
