There are many types of ear anomalies that may be present at birth (congenital ear deformities). These can be broken down into 2 major groups based on how they are treated. Ear malformations occur when there are missing elements of the ear. These conditions typically require surgical correction later in life.
In ear deformities, or deformations, all parts of the ear are present, but they may be abnormally shaped or positioned, or have abnormal folds. Some of these conditions may self-correct over time, but others may not. These types of ear anomalies may be corrected non-surgically during infancy by a process called ear molding.
