Are my expanders placed too far apart? (photos)

They appear to be far apart; however, they are centered over your nipple/areolas.   The medial cleavage can be improved with more medial positioning of the new implants. 

Thank you for your question and photographs.  Without before surgery photographs it is difficult to offer definite recommendations, but it appears that your expanders are placed appropriately within each breast pocket.  Because of the nature of two stage breast reconstruction, some degree of adjustment can be made to your implant pocket at the time of final implant placement to help improve your overall breast appearance, but remember that the implants should be placed so that they sit centered behind your nipple.  Hope this helps.

Thanks for the posted photos. But your chest/breast anatomy dictates the appearance of widely set reconstructed breasts. Best to discuss with your PS... 

Based solely on your photos, I would say that your expanders are actually pretty well centered under the nipple-areolar complexes; which is what we try to do.  Perhaps they could stand to be a little closer together, but it looks as if you stated with breasts that were a bit spaced apart to begin with.  I also note that the right tissue expander is a tiny bit higher than. the left.  By all means share you concerns with your Plastic Surgeon, but, based on 25 years breast reconstruction experience, I will tell you than minor malpositions are extremely common.  I recommend you just hang in there with the expansion.  These minor issues can all be worked out at the second stage procedure when the permanent implants are put in.  Best of luck.
