Does this spot at my T junction post breast reduction look ok? (photo)

The T point in a reduction or lift is vascular watershed located at the confluence of multiple incisions. As a result, vascularity is relatively compromised. Additionally, this is generally an area of elevated tension. These 2 factors combined will often lead to delayed healing.
Your situation is not uncommon. It is typically not a cause for significant concern. These wounds in most cases will heal on their own with local care and infrequently require operative intervention. 
Constitutional symptoms (such as fever, chills, rigors) as well as redness, swelling, or increasing pain or drainage is suggestive of infection and should be red flags.
As always, discuss your concerns with your board certified plastic surgeon (ABPS).

Your concern is very common in inverted T reductions.  The intersection of the incisions tends to be not only a point of higher tension, but also a distal point of the skin with the least vascularity.  These issues can  combine to create a delay in healing, but it usually heals within a few weeks with simple dressings like dry gauze or a band-aid.

Thank you for your question. Everything looks normal. Sometimes the area at the T junction is the slowest to heal after a breast reduction. It will heal with time and the scabs will drop off.  Good luck!

Thank you for your question and photos. At three and a half weeks post operative, you look to be doing well. It is not uncommon to have some wound healing issues after a breast reduction, particularly at the "T" junction, but in your case, you appear to be healing up just fine. The crusting will typically come off in the shower, but at this point. all looks well.Hope this helps,Best wishes,Dr. Morrissey
