METHODS: This study was a retrospective chart review of patients 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 stenosis.
RESULTS: Data from 26 individual patients (7 patients from our own case series and 19 patients from previously published reports) was analysed to calculate those patients requiring surgical intervention.
CONCLUSIONS: A PA width of less than 5.7 mm in a neonate is 88% sensitive and specific in predicting that a patient will require surgical intervention.
