In some cases, there is only one ear affected, and the contralateral (other) ear is in the ideal anatomical position. These patients can have just one ear set back. In most cases, both ears are affected to varying degrees. If only the most affected ear is set back and not the less affected ear, then the postoperative result will be very distracting and cosmetically asymmetric. It is often recommended to perform the surgery on both ears so that the position the ears are set back to will match and result in natural and pleasing ear appearance.
