This is what I'm concerned about with spitting stitches and the hole (Photo)

This is a very manageable problem, and not unheard of with surgical procedures of any kind. I'm partial to silver impregnated alginate dressings to pack such wounds every other day. The dressing changes are easy, and the silver kills all bacteria. Once healed, your surgeon might consider surgical revision of the scar in that location. Continue to follow up closely with your surgeon.

Thank you for the question and the pictures. It would appear as though you have suture abscess, a localized infection around the knot of the suture. These are remedied by unroofing the area and removing the affected suture. With local wound care the wound will usually go on to heal, without much impact on the appearance of your scar. I recommend to continue in close follow up with your plastic surgeon, they are in the best position to evaluate and treat you during your post operative recovery. This will allow you and your surgeon the chance to discuss your concerns and help allay any anxieties you may be experiencing.I hope this helps. Best wishes.
