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. We report a sibship in which a wide variation of expression is present and recessive inheritance can be postulated.
外耳的遗传性畸形,如小耳畸形和耳道闭锁,若不伴有其他先天性缺陷或综合征,则鲜有报道。仅有少数家族病例被描述,其中既有显性遗传也有隐性遗传的推测。我们报告了一个家系,其中存在广泛的表型变异,可假定为隐性遗传。
