Ear Otoplasty Stitching - when Does It Come Out?

It sounds like your surgeon placed absorbable sutures behind your ears, and most of them likely fell out by now. If there are a few remaining stitches that are bothering you, visit your surgeon and he'll remove the rest.

I hope this is helpful for you.

Permanent non
absorbable skin sutures are typically removed in 7 to 10 days following
otoplasty.  When sutures are left
in place for longer periods, several potential problems can occur.  Although increased pain may occur with
late suture removal, this is rarely a problem.  In the vast majority of patients, the most significant consequence
of delayed suture removal is increased scarring.

It’s important to
realize that no two patients are the same and that in some cases it may be
appropriate to leave sutures in place for longer periods of time.  If you have questions about this topic,
it’s important to discuss them with your surgeon. 

Judging from your multiple previous posts, I would highly recommend that you contact your original surgeon even if they are located at a distance or at least contact them by phone. Non-Absorbable Sutures should generally come out by this time (usually 7-12 days) or you may risk the possibilty of train track marks.
