There is internal stitching, but why is it indented with a fat pocket above it? Will it go away? (Photo)

Thank you for this interesting question.  It appears that your plastic surgeon has done a capsular repair of an implant that fell too far to the side.  This type of repair is called either a capsulorrhaphy or a capsulopexy.  In a capsulorrphaphy, that portion of the pocket that has been previously overdissected is closed by sutures imbricating (sewing together) two sides of a breast implant pocket.  At times, these sutures may also grab some of the dermis of the skin leading to an indent which also gives the impression of a fat pocket above.  Most plastic surgeons use dissolvable sutures and therefore these indentations most always go away.  That being said, you should contact your personal plastic surgeon and get his or her opinion after an in person consultation.

If your surgery was performed recently (less than 3-4 months ago) I would just give this time and keep in close contact with your surgeon.  If this is a long-standing indentation then revision may eventually be necessary and there will likely be a few surgical  options from which you could choose. Often times these issues self-correct.

surgery suggests some internal pocket work was done and it can cause retraction deformities on your skin.  As the skin stretches or the sutures dissolves or both, the dent should improve with time.  If ti does not, your surgeon can usually release the tethered tissues through a small incision that can be done in the office under local.
