6 weeks post-op. How long until this will heal? Do I have a stitch abscess? (photos)

Dear galambert,
This type of wound can occur 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.

based on your photos, it appears that you have sustained skin breakdown (epidermolysis) at the "T" part of your incision. The "T" is the junction of 3 skin flaps and skin necrosis or breakdown in this area is not uncommon. Consult with your plastic surgeon regarding local woundcare preference. Good luck!

Hi and welcome to our forum!
The operative procedure of mastopexy (breast lift) involves
separation of the skin and soft tissues of the breast from underlying breast
tissue. The skin and soft tissue is then advanced downward and the excess skin
and soft tissue is removed in an inverted "T" fashion.  
If there is impairment of the blood supply to the breast skin and
soft tissue, the segment of the flap the greatest distance from its blood
supply may not survive (at the junction of the inverted "T" flaps).
The cause of the blood supply impairment can range from effects
of smoking, diabetes mellitus, vascular disease, previous surgery in the
area (disrupting the normal blood supply), infection, or may totally inapparent.  
Treatment consists of removal of the unhealthy tissue, followed by
intensive wound care. One looks for the development of granulation tissue, a
beefy red vascular tissue, to develop, after which time the wound will begin to
shrink. Most wounds of this size will seal over a span of 2-3 months. 
Your wound is granulating and appears free of infection. 
Continue close followup care with your plastic surgeon. I am often surprised at how well these scars often heal!
Best wishes...
