Symmastia is a complication of breast implant surgery where the breasts have the appearance of being fused in the middle. The area of cleavage between the breasts is obscured by a bridge of tissue that seems to connect the breasts in the middle. Symmastia results from the surgeon dissecting too far medially or too close to the center of the chest when creating the pocket for the implant at one or both breasts. This allows the implants to lie very close together in the middle of the chest and at times the implant spaces may even communicate. This problem is corrected with revision surgery. Capsular tissue or graft material is used create a barrier between the two implant spaces and any communicating space is obliterated.
