Choanal atresia is a congenital disorder in which the nasal choanae, (i.e., paired openings that connect the nasal cavity with the nasopharynx), are occluded by soft tissue (membranous), bone, or a combination of both, due to failed recanalization of the nasal fossae during fetal development. If unilateral, it presents with unilateral mucopurulent discharge. If bilateral, the neonate is unable to breathe. Since newborns are obligate nasal breathers, establishing an airway is an acute otolaryngologic emergency.
