Cryptotia, Familial

Cryptotia is a congenital auricular deformity in which the upper pole of the cartilage is buried beneath the scalp. The incidence of cryptotia is said to be higher among Japanese than Caucasians and to be approximately 1 in 400 (Hayashi et al., 1993). Six individuals in 2 generations, with 2 instances of male-to-male transmission, were affected in the family reported by Hayashi et al. (1993).
