Do the irregularities after explanation represent the original inframammary crease and/or adhesions? How to resolve? (photo)

This is commonly seen in the setting of an explant where the initial augmentation was performed in a constricted lower pole where the fold was lowered initially. This can a challenging revision which will typically require re-operation with excision of lower pole excess scarring and re-suspension of the tissue at the higher native fold. Fat grafting may also play a role in softening the transition.As always, discuss your concerns with a board certified plastic surgeon (ABPS).

You most likely have some scar tissue there.  You may need to have the scar tissue removed and/or fat grafting to help the lower breast contour.

Based on the photographs, this is not an uncommon appearance after implant removal.  It appears that the skin and breast tissue have stretched out.   In my experience surgery to release the scar without re-implantation is not successful.

Thank you for your purchase. I'm not really sure why fat grafting overtime would not be helpful along with scar release. I was multiple consultations to try to get a consensus on what would be the best method for you.

This is one of the problems of removing implants that have been in long term and when there is not a lot of native tissue.  This can be loose skin, it can be capsule issues, and you may not be able to correct this without replacing an implant.
