Is this a problem? Hole in my incision growing larger and deeper but I have a line of stitches hanging out. (Photos)

Sorry to hear that you are having these problems.  The exposed suture material needs to be removed, and the opening should be able to heal with thoughtful wound care, measures to reduce the risk of infection, and good nutrition.  I would encourage you to follow up with your surgeon, but if they make themselves unavailable, find a plastic surgeon willing to help or search out a local wound care center.

You have a wound separation. This is pretty common and can even happen this late in the process. Your wound needs to be evaluated by your plastic surgeon. Speak with them again and if they’re really not available inform them you will seek help with a wound care center or a second opinion with an available plastic surgeon. Good luck.

Thank you for sharing your question and photograph and I am sorry to see your wound-healing difficulties. In cases of incision separation the initial wound can worsen a bit before your body starts to heal.  I would contact your surgeon to alert them of your issues so that they can offer you the best local wound care advice.  They will also want to remove the suture material that has started to hang.  Hope this helps.
