OBJECTIVES: Congenital nasal pyriform aperture @entity850 (CNPAS) is a rare cause of @entity1224 in the newborn. CNPAS is diagnosed clinically and confirmed with CT scanning. Early diagnosis and management is essential for this potentially life-threatening condition. @entity1 can be managed conservatively or surgically. Surgical treatment is usually reserved for those @entity1 that fail conservative treatment. Our objective was to provide a radiologically-measured pyriform aperture (PA) width that predicts the need for surgical intervention. METHODS: This study was a retrospective chart review of @entity1 treated in a tertiary paediatric hospital as well as a review of the literature. Outcome measures were defined as surgical or conservative intervention for the management of congenital pyriform aperture @entity850 . RESULTS: Data from 26 individual @entity1 (7 @entity1 from our own case series and 19 @entity1 from previously published reports) was analysed to calculate those @entity1 requiring surgical intervention. CONCLUSIONS: A PA width of less than 5.7mm in a neonate is 88% sensitive and specific in predicting that a @entity1 will require surgical intervention.

Congenital nasal pyriform aperture XXXX 5.7mm or less is associated with surgical intervention: A pooled case series.
