3 weeks post Breast Augmentation with yellow tissue/separation on T junction. Is this normal?

This T area is where maximal tension occurs and therefore the most common area of breakdown. This can be tension only or infection and/or suture spitting. I recommend dry dressings or silvadene until healed. At 3 weeks the chances of implant exposure are very low so you should be ok to heal.

The blood supply at the inverted T is always a problem and so wound healing problems at that spot are common. Basically the skin died from a lack of blood circulation. It should heal nicely for you but it will take several weeks so be patient and in touch with your surgeon.

Hi Alyssa,  Some skin in this area has died.  No cause for alarm.  This happens a lot because the blood supply in this area is decreased.  See your doctor immediately. He/she will probably start you on some "local care" until it heals in with new tissue over the next couple months.  All the best, "Dr. Joe"
