Choanal atresia. Report of seventeen cases

Seventeen cases of choanal atresia are presented, of which 13 were female and 4 male. In 11 patients the malformation was bilateral, being unilateral in the remaining 6; 8 patients also presented other malformations amongst which esophageal atresia and congenital heart disease were the most common. Treatment is surgical, and the prognosis depends largely on the presence or absence of associated malformations.
