Surgical bra vs bandages post-op? What's the difference?

This is a matter of surgeon's preference.  No study to my knowledge has shown a better long term outcome with either post operative garment.

Hi.  Personally I use minimal dressings and an elasticised tubigrip for the first week then into a bra.  The main thing is comfort and any of the techniques you describe are fine and will not affect the implants.  Regards
