I Had an Otoplasty in Nov 2011, Completely Failed, Reversed to Original Appearance Within 3 Months?

Based on the pictures, I think your surgeon did a good job. The ear is set back or at a position that is close to ideal. If you get them pinned back more they will be too pinned back in my opinion. But you are the person that should be happy. You can get them pinned back more but you should understand that this may not be what people will view and perceive as normal.
 

Otoplasty relapse is either due to suture loosening or too much cartilage stiffness. Given that the suture issue has been addressed, further and more stable improvement is going to come from weakening the natural stiffness of the cartilage to eliminate its recoil potential.

As we age our ear cartilage becomes less pliable and more stiff.  Otoplasty in adult patients often protrude with time if sutures alone are used to hold the ears in a less prominent position.  This may  work for children, but in adult ears, some cartilage weakening is necessary to prevent the issue you have experienced.
