Symmastia 4 weeks post op?
I think your photos suggest you have an excellent early result. I think using a push up bra so early after a revisional procedure is a little risky though and something you need to check with your surgeon that it is ok. Sometimes the additional pressure on your sutures from the bra can cause a recurrent problem.
Given your result so far I think your surgeon was sensible not to use alloderm or another ADM. I am guessing that they thought it wasn't necessary and may add extra risk to the procedure but I'm sure they will be able to fully explain their rationale.
All the best,
Your results in the middle photo looks excellent. I would follow your surgeon's advice. Best of luck.
From your photographs, your revision of the bottomed out implant looks wonderful to me. I would ask your plastic surgeon if they want you putting pressure towards the inside of the pocket with a push-up bra this early postoperatively. Congratulations on a nice result.
Evaluating early results from bottoming out repair
Your surgical result looks quite good at this early stage of healing after revision. Wearing a push up bra can work against the repair however so please follow your surgeon's advice.
