A good otoplasty result is one you stop noticing — ears that look natural and proportional, set in a comfortable position rather than flattened against the head. The two ears should match, with soft, real-looking curves rather than a sharp, over-corrected line.
As with any surgery, results vary from person to person, and a small difference between the ears is normal — perfect symmetry isn’t the goal. A balanced, natural improvement is.
Ears that simply suit the face — not the first thing you notice, and not pinned flat.
