Ear Malformation

Potter (1937) described a bilateral congenital malformation of the pinna which is curled up like a cap or cup concealing the external auditory meatus when the subject is in lateral profile. Erich and Abu-Jamra (1965) observed transmission of the condition through 4 generations (in 17 cases in 8 sibships) and reviewed similar reports. Peterson and Schimke (1968) observed cup-shaped ears in members of 5 generations with at least 4 instances of male-to-male transmission. Their proband had Pierre Robin syndrome (261800). The embryology of the auricle and a large amount of clinical material on various anomalies of the auricle were presented by Rogers (1968).
