Your right about the asymmetry. Without seeing a front view, it's hard to know which ear over/ undercorrected. I agree with Dr. Putman that "pinning" the prominent ear and adding a strut to project the overly corrected ear would likely be the best option. Although it is probably easy for you to reproject the ear that is closer to your head, it will be challenging to do that surgically in a way that will create stable and long-lasting protrusion. I hope this information is helpful for you.

Depending on the type of cartilage sculpting and suturing, as well as amount of skin removed, it may be possible to correct the recessed ear to better match the opposite one. However, a slight adjustment in the degree of protrusion of the opposite ear may be needed to achieve optimal symmetry. Talk to your surgeon beforehand about these possibilities.
