What a mixed shape looks like

Each feature may be mild, but together they change the ear’s overall look. One ear may show several features while the other has one, or none. Common combinations include Stahl’s ear with prominence, conchal crus with prominence, and lidding with a helical rim difference.

How it is assessed

The clinician identifies each feature, how firm the cartilage is and how the features affect one another. This helps decide whether molding is likely to help and how the device should be fitted.

Is molding considered for mixed shapes?

It may be. The device can be fitted to address several features at once. Mixed shapes can need careful adjustment over the course of treatment, and the clinician will explain the expected response for your baby. Treatment timeline.
