Should I be concerned with my incision opening? (photo)

Dear sadie133,this type of wound is not uncommon after breast lift. It is usually caused by poor blood flow or suture spitting. I would suggest you to consult your plastic surgeon, follow your surgeon's instructions and keep your wound clean and covered. It can take few weeks or months for wound to fully heal. Daniel Barrett, MD

This is not uncommon to find after breast lift and augmentation surgeries. I would see your PS to make sure you do not have a suture that needs to be removed. This will otherwise prevent your incisions from healing.  Oral antibiotics are also helpful to aid in healing.  Over time these usually scar fairly well, but if they do not, a scar revision would help. 

Thank you for your question and photo! It seems you could be having a possible suture spit.  I suggest you call your plastic surgeon and make sure you are following all post op! Best of luck!Dhaval Patel

Judging by the photos the wound appears superficial and likely the result of a spitting suture.  I would follow up with your surgeon and follow the recommendations of your plastic surgeon.It may take a few weeks to a month or so before the area heals, so you have to be patient and care for it until the wound closes.  I would say it would be likely that everything will heal without any major issues.Hope that helps.

Thank you for your questions and your photo. You are still healing so you should continue to follow your plastic surgeon's post operative instructions carefully and address any questions in your healing with them. Good Luck.
