Incision opened up. Is this normal? Will my scar be really bad? (Photo)

Thank you for your question and photos.  From what I can see, you appear to have some superficial healing delay.   This could be due to external irritation, systemic issues like smoking, or inflammation due to the sutures.  This sort of problem will typicall resolve with local wound care.  You may have wider than ideal scar, but this can be fixed at a later time with a scar revision.  Best to follow your surgeons wound care advice.  Good luck.  

Thank you for your question and photo. It appears that you have some superficial separation, which is most likely due to reaction to the suture material. This should heal uneventfully with wound care. The scar may heal a bit wider, but this certainly could be revised if needed. I encourage you to have your plastic surgeon evaluate you, because obviously if the opening goes deeper, to the level of the implant, this could become a bigger problem. That being said, from your photos, it does appear to be superficial. Obviously, an in person examination it Is necessary to make a better assessment. Best Regards.
