Abstract
Introduction

Congenital nasal pyriform aperture stenosis (CNPAS) is an uncommon malformation and a rare cause of respiratory distress in neonates that may require early surgical intervention.

The aim of this study is to report our experience in patients operated for CNPAS and present characteristics of this population.

Material and methods

A retrospective, analytical cohort study was conducted of patients who underwent surgical treatment for CNPAS in the Hospital de Pediatría Garrahan from May 2008 to May 2018.

Results

Nineteen patients underwent surgical treatment; 47.36% had some associated genetic syndrome. The surgical approach was sublabial. Follow-up was more than 45 days in 14 patients, 9 did not require additional treatment, and the remaining 5 required further surgical and/or medical treatment. Short-term post-surgical outcome was good in 85.7%.

Conclusions

Better post-surgical results were obtained in patients in whom endonasal stenting was not used and who did not present associated craniofacial malformations.
