What Are These White Plastic Things Trying to Work Themselves out of my Skin?

One assumes you have a surgeon who operated on you. Ask him/her, it is totally inappropriate to ask doctors who didn't operate on you.

Dear PCR,

Your surgical team may have used a type of stapler that places a staple under the skin that is designed to dissolve over time.  To the patient, they often look like a white or pale colored U-shaped structure that sits under the skin's surface.  These will usually dissolve in a few months but in some patients, they can persist and if that occurs, your surgeon may have to remove them.  This is something that can usually be done in the office with just a little local anesthesia.  Please bring your concerns up to your plastic surgeon who can advise you on which course of treatment is right for you.  Hope this helps.
