Am 3wks post op, Is this a breast lift gone wrong? (photo)

Thank you for the question. This is a common area to have
wound breakdown after a Wise-pattern lift. It looks
superficial.  This should heal spontaneously, however, your scar will probably be slightly wider, which is usually not a major problem for most women. You should see your surgeon frequently to make sure this is healing and there is no added infection that might require further treatment. I would keep the area clean and avoid any strenuous
activity/lifting, smoking (if you are a smoker), underwire bras or anything
that places excess tension on the incision. Your surgeon is the best person to
talk to.

Dear mary0821,
I understand your concern. Based on your photos, it looks like there is wound separation. In most cases this will heal with time. You need to keep the wound clean and covered. However, without a proper assessment, it would be difficult to determine what went wrong. It is best that you visit your plastic surgeon for further assessment or ask for a second opinion. Only after a thorough examination, you can get proper recommendations and advice.

It is not uncommon to have a small opening in that area, just keep it dry and no ointments and it should close within a couple of weeks.
