Nerves which control sensibility to the nipple run in grooves under the ribs and send branches up to the skin as they go. These are next to the breast bone in front and at the side of the chest. Breast implants lie between them, but the nerves can be damaged when the surgeon is opening the pocket to house the prosthesis.
Numbness of the nipple is a rare, but definite possibility post-operatively and may be permanent. They may interfere with breastfeeding, sexual gratification, etc., and, small though the risk may be, you should weigh this in your decision to have the surgery.
I hope this helps,
