title: [Choanal atresia: review of embryology and pathogenesis].
abstract: In the paper a study on the embryology and pathogeny of choanal atresia is presented, with particular reference to its association with other congenital malformations. The experience of the AA., gained through 10 of those cases seen at the ENT-department of the Servasa Hospital, Alicante, is the low incidence of coexisting malformations. They emphasize one case of familiar presentation (mother-daughter), other with eye coloboma and bifid uvula coexistence and a last one with a sensorineural deafness of moderate degree.
