Incision reopening after breast augmentation 1 month ago - should I be worried? (Photo)

Thank you for your question and photograph.  Your photograph indicates a small area that may be an opening where suture material is finding it's way to the skin surface.  This is known as a spitting stitch and generally heals quite well.  My advice is to follow-up with your plastic surgeon for his/her specific instructions.  Good luck.

The problem could be as simple as a necessitating suture but this condition needs to be examined by your surgeon. The sooner the better.

From the photo it appears to be a small stitch area and most likely not an issue but I would suggest you see your physician for an in person evaluation. You do not obviously want even a small open hole unattended. Be careful of your garments and keep in touch with your practice. Best of luck.
