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.
