It would be very helpful if you did mention how long has your surgery been done, because bruising and swelling are normal manifestation of healing in the early stages of recovery. Having said this, it would be difficult to give an accurate assessment based on photos. Your best course of action would be to schedule an appointment with your board certified plastic surgeon as he/she knows your condition best.
Hi thank you for your question. It is not always possible to be sure what is going on from a photo. Having said that your nipples and areolae look very bruised but are likely to be viable (alive). If you have concerns the best thing to do is visit your surgeon for a review.Best wishes.
