What happens if sutures aren't removed with spit stitch wounds? One month post op breast lift with implant.

When my surgical tape was removed, a scar opened up. I was told it was a spitting stitch, and was put on a wet to dry saline rinse. The wound is now over 8 times the original size. I had dissolvable sutures, but is it possible it's getting bigger because the sutures my body was spitting were never removed? I'm a healthy non-smoker.
