Microtia with meatal atresia and conductive deafness: Mild and severe manifestations within the same sibship

Abstract

Hereditary malformations of the external ear, such as microtia and meatal atresia, not associated with other congenital defects or syndromes, are rarely reported. Only a few familial cases have been described in which both dominant and recessive inheritance has been suggested. The authors report a sibship in which a wide variation of expression is present and recessive inheritance can be postulated.
