Nipple positions too close after a breast reduction. What are my options?

I'm sorry to hear about your concerns after breast reduction surgery; it would be helpful, for more accurate assessment and advice, to post frontal and side view breast photographs, with your arms by your side. Based on your description, it sounds like you may benefit from revisionary breast reduction surgery. Sometimes, removal of additional skin along the lower breast poles will help improve position of the nipple/areola complexes on the breast mounds.  Adjustment of the nipple/areola complexes may also help improve your overall symmetry. Best to communicate your concerns and goals directly with your plastic surgeon in front of a full-length mirror. It is very likely that working together you will come up with a good plan to achieve an outcome that you are happier with.

Hi and thanks for sharing,
Nipple areola malposition following breast reduction can usually be rectified with revisionary surgery - with that said however, it is usually easier to elevate a nipple that is too low on the breast rather than move a nipple down that is sitting too high.
Part of the problem is usually that the distance between the bottom of the areola and the inferior breast fold is relatively long and the position of the nipple can be improved by reducing this distance - usually by removing a wedge of skin and tissue from the inframammary fold and then stitching the new fold down hard onto the chest wall - the result will be a nipple that sits in a better position on the breast mound.
I'd suggest going back to your PS to discuss your concerns so that you can plan together the best step going forward.
Best of luck
