What's Going on with my Nipple? (photo)

It does look like you have some tissue loss on the areola unfortunately, and it may be deep. It is a rare risk of surgery.

The photo demonstrates partial loss of viability of the areola. There is a good chance that is the eschar separates in the areas given the opportunity to heal it might look fine.

Unfortunately, you have full-thickness (deep) tissue loss.  These area will peel off eventually when the healing is complete beneath.  This healing will result in some contour issues with the nipple and areola.

   Areolar Necrosis can occur, and yours appears to be at least superficial.  If it is superficial, the areola should do very well with time.  Kenneth Hughes, MD Los Angeles, CA

Unfortunately, you suffer some loss to your nipple.  This is a very rare but recognized complication.  It can be more common in smokers.  Let it heal and probably nothing else will need to be done after time and massage.  However, you may need revision to the nipple but I would wait 6-12 months.  Good Luck.
