MADRIGAL, Marina et al. Congenital nasal pyriform aperture stenosis: unusual form of nasal airway obstruction. Rev Esp Cirug Oral y Maxilofac [online]. 2014, vol.36, n.3, pp.129-131. ISSN 2173-9161.  https://dx.doi.org/10.1016/j.maxilo.2012.08.001.

Congenital nasal pyriform aperture stenosis (CNPAE) with a single mega-incisor is an uncommon form of nasal airway obstruction in the neonate. Its low frequency and its similar clinical presentation may lead us to a wrong initial diagnosis of choanal atresia, which is more frequent (1:5000 live births). CNPAE may be a minor form of holoprosencephaly, so diagnosis should include screening for heart and central nervous system abnormalities. A case of a newborn with CNPAE is reported.
