This assessment will guide you through the most common types of infant ear shape deformities— what they look like and why early evaluation matters. Many ear shape deformities can be gently corrected with non-surgical care when treated at 3 weeks of age.
When one or both ears stick out more than usual from the side of the head. (The most common infant ear deformity)
The upper part of the ear folds over or down, sometimes making the ear appear soft or bent. (Presents in over 25% of all infant ear deformities)
Many babies have a combination of conditions — such as lidding with conchal crus, or prominent with Stahl’s
An extra fold gives the ear a pointed or angular appearance.
Flattening or folding along the outer rim of the ear that changes its natural curve
A ridge of cartilage crosses the center of the ear, making it appear visually divided.
Prominent (or protruding) ears are diagnosed when the ears extend over 2 centimeters (about ¾”) from the skull. Ears that stick out are frequently caused by missing natural folds or underdeveloped ear cartilage.
Uneven shapes in one or both ears can indicate newborn ear deformities. Common types include:
When one ear differs from the other in size, shape, or folding, this asymmetry is a sign of ear deformities that may require early intervention.
Babies may develop flattened, crinkled, bent, or inward-pressed ears due to their position in the womb or post-birth. Such flattening is another common ear deformity that can be corrected with early molding.
If the upper ear lacks definition, particularly the antihelical fold, it may indicate an underlying ear deformity.
Only 30% of ear deformities correct on their own—and there’s no way to know which will. Early treatment helps ensure the most natural result and may prevent surgery later.
