Hearing in Patients with Congenital Meatal Atresia.
—The large majority of children with unilateral congenital meatal atresia have a normal internal ear on the affected side. This end-organ of hearing is constantly stimulated by sound vibration through the bone, and probably no reduction in hearing occurs if surgical interference is delayed until the infant is old enough to have an accurate audiometric test. When one is dealing with extremely nervous parents psychogalvanometric testing may be indicated. If the audiometric testing at the age of 3 to 4 years demonstrates normal hearing in the uninvolved ear and a relatively normal internal ear on the affected side, operation is probably not indicated. In any event, it is best to reconstruct the auricle first and later provide a skin-lined opening into the antrum behind the constructed auricle. Skin-lined openings made in the canal region through the cartilage substance of the constructed auricle
