Abstract

A six-year-old female with congenital bilateral choanal atresia was examined by CT (computed tomography) and contrast radiography. CT clearly demonstrated the existence of choanal atresia, and differentiated osseous stenosis from membranous stenosis in the choanae. CT may be the first choice of radiological examination for the pre-operative diagnosis of congenital choanal atresia.
