Constricted Ear in Babies: What Can Molding Do?

A constricted ear looks as if a drawstring has been pulled around the rim: the outer edge is tight, the top is folded and the ear is smaller than usual. Lop ear and cup ear are milder forms on the same spectrum.

Short answer: Mild constricted ears can often be improved with ear molding started in the first weeks of life. Severe forms, where cartilage or skin is short, may improve only partly and may need surgery later.

• Look: the rim is tight and the ear looks small or hooded.
• Top: the upper ear folds over.
• Size: the ear is shorter than the other ear.

What causes constricted ear?

The rim of the ear did not develop fully, so there is less cartilage and skin around the edge. The cause is developmental.

Will constricted ear correct itself?

Some mild folds caused by the baby’s position in the womb improve in the first days after birth. When the shape is still visible after the first week, it is less likely to correct itself, and waiting uses up the weeks when the cartilage is softest. An early examination lets the physician decide whether to watch or to start molding. More: do babies grow out of ear deformities?

Can constricted ear be corrected without surgery?

In mild and moderate forms, yes. The device gradually expands the rim and holds the upper ear open while the cartilage is soft. The physician explains how much improvement is realistic for your baby’s ear.

Molding works best when it starts early, because the cartilage firms in the first weeks of life:

• Started at 15–21 days: about 3 weeks of treatment.
• Started at 4 weeks: about 4 weeks.
• Started at 5 weeks: about 5 weeks.
• Started at 6 weeks: about 6 weeks.

These are average planning guides; the treating physician sets the exact course.

What happens if it is not treated?

Ear shape differences are usually cosmetic and do not affect hearing. Once the cartilage has firmed, the shape no longer responds to molding, and correction later in childhood usually means ear surgery (otoplasty). More: ear molding or otoplasty?

Frequently asked questions

Is a constricted ear the same as microtia?

No. In a constricted ear the parts of the ear are present but tight; in microtia part of the ear has not formed. More: microtia.

Is ear molding painful?

No. The device is soft and no needles, incisions or anesthesia are used. Some babies are briefly fussy while it is fitted and settle quickly.
