Some doctors will use these in place of surgical gauze/pads. However, this is a question that should be posed to your surgeon performing the procedure. Good luck with your procedure.
I suspect the recommendation for feminine pads are for use around the drains. Gauze and a number of other medical products can also be used. A 4x4 gauze pad folded in half and cut half way through makes an excellent drain sponge. Of course, when in doubt, you should always call and confirm with your plastic surgeons office.All the best,Dr. Remus Repta
