Are There Nipple Implants for Breast Reconstruction?

There are various techniques and options for nipple reconstruction - decision on which is surgeon dependent.  To answer your question, there are companies that create "structures" for nipples, which are meant to be placed beneath the reconstructed nipple flaps created with your skin.  I typically create the nipple using your own skin flaps at the anatomically-appropriate position.  Depending on the quality of your skin there will depend on if I use a nipple graft or not.  Often times when a flap is used for the breast reconstruction, the tissue is much thicker, and thus, grafts are not typically needed.  If a graft is required to add additional durability and projection, I personally do not use foreign substances.  I prefer to use your own dermis, which I harvest from one of your previous scars.  Finally, I like to tattoo the nipple-areolar complex rather than placing skin grafts as I find it more aesthetically-pleasing.

Nipple Reconstruction is an art and is typically performed after breast reconstruction. There are a myriad of techniques to reconstruct the nipple, including local flaps and subcutaneous cartilage placement.
These techniques are surgeon dependent. In general, the nipple resumes a normal shape and size but lacks the sensation of a normal nipple.
