Neonatal nasal obstruction and a single maxillary central incisor.
We present two neonates with nasal obstruction because of anterior choanal stenosis (congenital nasal pyriform aperture stenosis). An associated single maxillary central incisor was also shown on computed tomography imaging in the neonatal period. These midline anomalies are recognized minimal manifestations (microforms) of holoprosencephaly. We describe their neonatal investigation, multidisciplinary management and clinical course.
