Although relatively rare, disruptions in embryologic development can result in a variety of congenital nasal lesions. These primarily result in airway obstruction, either at the front of the nose (pyriform aperture stenosis), the posterior nasal cavity (choanal atresia), or sometimes within the nasal cavity (gliomas or encephaloceles). External nasal lesions are also possible (nasal dermoids). An understanding of the embryologic development of the nose and potential disruptions is important in understanding the surgical options to treat these patients, as medical options are limited. Preope
