Can my ears be pulled farther from my face and allow me to tuck my hair behind my ears?

Yes, you can move the ears away from the head but it's a much more complicated procedure... as for the normal otoplasty surgery, this places the ear closer to your head and yes, you should be able to put your hair behind your ear after this surgery.

I am sorry I don't understand the first question. Did you mean can ears be pulled CLOSER to the face?

Otoplasty (ear pinning or set-back) allow the ear to be placed closer to the face and is a wonderful procedure with a high satisfaction rate.  If the ear is placed at an appropriate (normal) distance from the face, you will be able to tuck you hair behind your ear.

The technique which I use places the scar BEHIND the ear.  Best of all, the procedure can be done under local anesthesia, if desired.

I believe you are asking whether the ears can have a great angle or distance from the side of the head, an increased auriculo-cephalic angle. This is the reverse of the typical otoplasty or ear pinning request. It is possible...yes. But it would require rib cartilage grafts to hold the new shape of the ear outward as expansion requires a structural support. Whether that effort is worthwhile would depend on how bad your present ear position and shape bothers you.
