Choanal atresia can be an isolated anomaly, but it is frequently associated with other congenital conditions. One well-known association is with CHARGE syndrome, a complex condition that includes Coloboma of the eye, Heart defects, Atresia of the choanae, Retardation of growth and development, Genital abnormalities, and Ear abnormalities. Therefore, a thorough evaluation for other anomalies is recommended when choanal atresia is diagnosed.
