Tiny hole incision/spit stitch? (Photo)

Thank you for your question and photograph.  Based on the photo and your description your diagnosis of a spitting suture  is most likely correct.  Ideally your plastic surgeon should remove this suture.  You can however consult her primary care physician to see if he or she is willing to remove the stitch or give you a referral to a local plastic surgeon.

That small hole looks fairly insignificant and it sounds like it is a spitting dissolving suture. It is likely safe to trim what you can feel with a clean pair of scissors. Why don't you send your pics to your surgeon and see what they say. Otherwise your incisions look good so far.
