The Role of Computed Tomography in the Evaluation of Bilateral Choanal Atresia: Two Case Reports

چکیده
Congenital posterior choanal atresia is an uncommon anomaly which may have lifethreatening consequences. This defect is frequently associated with other congenital abnormalities. CT scan confirms the diagnosis and accurately defines the anatomy of the atresia and differentiates osseous stenosis from membranous stenosis in the choanae. Therefore, CT may be the first-line imaging choice for the pre-operative diagnosis of congenital choanal atresia. We present two cases of bilateral bony choanal atresia, of which one is associated with bilateral coloboma.
