Can I Increase the Space Between my Breasts with Cosmetic Surgery?
It depends on why your breasts sit close together. If implants have migrated toward the middle — a condition called symmastia, where the two pockets connect across the sternum — that is correctable: the surgeon repairs the capsule with internal sutures to rebuild the boundary between the pockets, sometimes reinforced with supportive material, and may switch to narrower implants. If your breasts are naturally close, cleavage spacing is largely set by where your breast tissue and skin attach to the breastbone, and detaching skin from the sternum risks a deformity worse than the closeness. There are still levers to pull: implants of an appropriate width, pockets positioned slightly more laterally, and avoiding oversized implants that push toward the midline all influence spacing at the margins. What surgery cannot safely do is manufacture a wide gap on a chest built with a narrow one. An examination by a board-certified plastic surgeon will tell you which situation you are in and what is realistic.
Clinical Context
Breast spacing is largely determined by anatomy: the sternum and the point where breast tissue naturally begins on each side of the chest. Skin over the breastbone is thin and closely attached to bone, so surgeons avoid disturbing that area during implant placement. This is also why creating true symmastia during surgery is a recognized risk when pockets are made too wide or implants are oversized — understanding this helps explain why 'natural closeness' and 'symmastia' require very different surgical approaches.
