I Am Noticing a Nasty Odor Around the Nipple Graft Area, Could It Be Infected?

I would recommend that you call plastic surgeon right away - there is no substitute for an examination and you might have an infection that needs to be treated. 

 Thank you for the question.

Unfortunately, the only way you will have real peace of mind is to be seen by your plastic surgeon for direct examination. This is  the only way to check for signs of infection.

Best wishes.

It is possible that you either have an infection or necrosis of some of the tissue (it did not survive). Typically, this is often checked by one week. 

I recommend that you contact your plastic surgeon immediately to have him/her evaluate the status of your nipple-areola graft. This would obviously involve removal of the bolus dressing.
