Hole on my tummy tuck line won't heal, what can I do? (photo)

Your plastic surgeon should be able to give you advice on how best to care for this wound. They need to examine the wound to determine the reason its not healing. Wounds like this can take quite a while to heal and if there is something that is preventing it from healing then this factor needs to be addressed. The wound should be clean, without any foreign bodies or debri, you should not be smoking and any non living tissue needs to be cleared. I find wet to moist dressing changes with normal saline is a very good and simple way to heal wounds. But as stated before, you should follow the directions of your plastic surgeon.

Thank you for your question and pic.   It appears that you may have a spitting suture which is not uncommon with this type of procedure.  Please see your plastic surgeon to see if by chance the suture can be seen and removed.   best of luck.  

Thank you for sharing your question and photograph. When wounds pursue the path you describe it is most likely due to some material at the base of the wound, such as a stitch.  I would reach out to your surgeon for an in-person evaluation and removal of any foreign body.  Hope this helps.
