Otoplasty 2 Weeks Ago: Have a Hole on the Front of my Ear and a Suture Poking out of the Top, Are They Infected? (photo)

Thanks for these questions. You should check with your surgeon about suture removal. It is not necessarily infected. In many cases the suture is permanent and exposure of such a stitch should be removed. Good luck!

You should go see your surgeon. It does sound like you have a suture extruding. It may need to be removed.

I hope you have already seen your surgeon as this is not expected and problems can develop if unchecked..

This could be a suture that is having some issues. I would definitely return to my surgeon to have him look at it. All you would have to do is remove and do really careful cleaning to avoid healing issues.
 

These represent extruding and/or infected sutures.  You should see your surgeon immediately. 

If there were no incisions made in this area to reduce the size of your concha then this is most likely an infected suture knot.  You should not delay having this examined and properly cared for prior to having a bigger problem.  

The pictures are not of sufficient quality to comment on either of you questions.  I would encourage you to discuss your concerns with your operating surgeon.  He or she knows the specifics of your original procedure and therefore provides the best resource when discussing the results of your surgery.
