چکیده
Congenital nasal pyriform aperture stenosis (CNPAS) is a very rare condition of the newborn, in which the nasal pyriform aperture is narrowed by bony overgrowth of the nasal process of the maxilla (Figure 1). As the narrowest point of the nasal airway, a small change in its diameter may significantly increase nasal airway resistance. As infants are obligate nose breathers for the first three months of life (or longer if premature), such an increased airway resistance causes functional airway obstruction and respiratory distress.

IMPORTANCE Congenital nasal pyriform aperture stenosis (CNPAS) is a rare cause of nasal airway obstruction in newborns. The decision to operate is made clinically. Although pyriform aperture width is used for diagnosing CNPAS, it does not fully characterize stenosis of the nasal cavity. OBJECTIVE To determine the utility of additional metrics for evaluating CNPAS. DESIGN, SETTING, AND PARTI...

Congenital nasal pyriform aperture stenosis (CNPAS) is a rare cause of nasal obstruction. We presented a case of CNPAS with accompanying short lingual frenulum. Surgical dilatation without osteotomy was used, and the infant had normal growth and development. In these cases, the less invasive surgical methods can be effective.

Congenital nasal pyriform aperture stenosis (CNPAS) is a recently defined clinical entity that causes airway obstruction in the neonate as a result of narrowing of the nasal pyriform aperture. The pyriform aperture is the narrowest, most anterior portion of the nasal airway, and a slight decrease in its cross sectional area will significantly increase the nasal airway resistance. This entity sh...
