What needs to be done to fix the otoplasty I have had done? I have already had 2 revisions on this ear and am worried. (photo)

I had otoplasty June 2013 and 2 revisions since on same ear.first time all was good then after 2/52 it sprung back.another revision and ok. not 100% wound on the back is still scabby and sore. I saw there was a silk suture thread hanging from the inside coming out through the incision. I emailed the ps and his staff told me I need to come in.app is in 2/52 What will he do?3 times is enough the back already looks awful. I'm worried about infection since I have this a open wound not healing.
