Subdermal implants to replace nipple projection

Have any plastic surgeons used silicon subdermal implants, similar to those some men use for penile enhancements, to recreate the projection of the nipples after a skin sparing, double mastectomy with reconstruction?

Have you encountered any complications, problems anchoring, rejection of the main breast implants or subdermal nipples implants, issues with scar tissue or any other unexpected outcomes?

Has anyone attempted using subdermal implants for any other body image reconstruction? Instead of filler?
