Thanks for your photos and question. The dent you show and describe is not a dent as much as residual loose skin that sags when your arms are down. This has become evident as your swelling has diminished and your skin softened and stretched (again).When your arms are up, your breast skin is tightened, and the residual loose skin is pulled up, eliminating the sag (dent) that shows up with your arms down.Since your scars appear to be fairly new, you are early in the healing process, and you can also expect your implants to drop somewhat over time. This may "catch up" with your loose(r) skin, and cease to be a concern. Frankly, it could also get worse. Ask your surgeon about this and be patient with the overall healing process before considering surgical revision. Best wishes! Dr. Tholen
