Wound opened after breast lift. Is this normal or infected? (Photo)

Dear selena201230,
this type of wound is not uncommon after breast lift. It is usually caused by poor blood flow. 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.

I am sorry to hear about the complication you are experiencing.  These types of complications can be quite (understandably) distressing to patients;  unfortunately, sometimes the wounds do look worse before they begin to look better. The wounds tend to occur where incision lines come together (where there is the greatest tension and least blood supply).  These types of wounds tend to be more concerning, if there is an underlying breast implant present; avoidance of implant exposure will be one of your plastic surgeon's concerns.
Close follow up with your plastic surgeon will be very important; sometimes removal of a exposed suture and/or removal of any unhealthy tissue will expedite healing.  There may be different treatment modalities recommended; best to "stick with" your plastic surgeons recommendations. Generally, this will involve application of some type of sterile dressing ( in my practice I use a non-stick dressing covered by a sterile dressing once a wounded is clean).   Also important to concentrate on a healthy diet, including good protein source.   Best wishes.
