Our classification of cryptotia is based on recognition that the deformity is the result of an anomaly of the intrinsic transverse and oblique auricular muscles. Our treatment, in the first instance, is a non-surgical correction. This should be started early, if possible in the first 6 months of the baby's life. Even in the case of older children, success can sometimes be achieved and a non-surgical correction should be considered first. If non-surgical management fails the deformity can be corrected surgically by dividing the muscle fibres that produce the anomaly of the external ear through a small incision. Our new surgical approach involves moving the available skin in the region of the inferior cephalo-auricular sulcus to the superior part where skin is needed by a rotation flap. This operation has several advantages.
