The most common problems, such as ears that are oversized or stick out, occur in both ears, which means both will need to be fixed. During ear surgery, Dr. Canales or Dr. Furnas will adjust both ears to make them as symmetrical as possible. However, if just one ear has to be altered, the shape and size will be adjusted to mirror the untreated ear. When they create your surgical plan, they will tell you if one or both ears need to be corrected.
