I am uncertain when this picture was taken in comparison to the date of your second surgery on June 14, 2018. In general, there is frequently some delayed healing after having extensive reconstructive surgery like you had, i.e. mastopexy, excision of fat necrosis, liposuction, and fat grafting. If this photograph was taken on June 15, 2018 or you have no sensation postoperatively compared to preoperatively then I would be concerned. If you still have sensation and this photograph is more than 3 days postoperatively then I would be less concerned and the risk of nipple loss is almost nil. In my practice, I like to use Venelex ointment twice a day and have found good results. It is possible, that you may have some local skin loss along the incision line, but this can be treated with local wound care.
