In my opinion, the photos show close medial fullness and some tightness of the skin between the breasts, but a true diagnosis of symmastia cannot be made reliably from these photos alone. Symmastia means the implant pocket has crossed too far toward or across the midline and the skin over the sternum is lifted off the chest wall. “Tenting” can also happen from large implants, tight tissues, swelling, or the way the photos are taken, without a true pocket problem. Because you have had an implant exchange with an anchor lift, your own surgeon should examine you and compare the current position with your early post-op course. If this is recent, some swelling and tightness can change as tissues settle, but if the implants are moving toward the midline, the cleavage skin is lifting, or the shape is worsening, it is better to be seen sooner rather than waiting. Treatment depends on whether this is true symmastia, implant malposition, or normal healing/tightness.
