Can someone please recommend a very good experienced surgeon for explant in Istanbul for me?

With capsulectomy operations I always use drains, and this is why.  The fluid that builds up after capsulectomy will not likely resolve on its own.   It needs to be drained.

I see exactly what you are referring to but zi can't give an exact answer without an exam. It looks like there is still capsule inferior to your original crease that has maintain a pocket and prevented your tissues from retracting up completely.  I suspect you need that redundant pocket,...

The periareolar incision should not cause inversion of the nipple.  It is not too invasive to use this incision.  Capsulectomy/capsulotomy should be decided at surgery.
