Congenital Choanal Atresia

Abstract
In 1990-1995 the authors treated 40 children (age 1 month to 12 years) with congenital choanal atresia (CA). Bilateral CA occurred in 4, unilateral in 36 children. Complete and incomplete CA were diagnosed in 37 and 3 patients, respectively. Other congenital anomalies were registered in 7 children. Fibroendoscopy and computed tomography proved best in providing diagnostic information, while endonasal method with finger control was most available. The optimal time of protector carrying was at least 2.5 months.
