I had an otoplasty two weeks ago but I feel as though they're pinned back too far, will that change?

During otoplasty procedures, the ears are almost always overcorrected somewhat to compensate for the tendency for the ears to move back out subtly over several months following the surgery.  Two weeks is probably too early to assess the final result.  Give it time!Good luck!

The ears generally do relax a bit with time after otoplasty and I would definitely not try to judge your results only two weeks after the procedure.  It can take 6-12 months for all of the healing to occur.  I would really give it at least 3 months before beginning to see what your results might be.  

Otoplasty results are not immediate. Some operations require over-correction so that when the ears heal, they will be in the best position. Two weeks is too early to judge.
