Congenital Nasal Piriform Aperture Stenosis or Bony Inlet Stenosis: A Report of Three Cases

Abstract

Background

Congenital nasal piriform aperture stenosis is an uncommon disorder causing nasal obstruction in neonates. Findings on computed tomography (CT) greatly facilitate the diagnosis.

Methods

Three cases of congenital nasal piriform aperture stenosis are reported, with an emphasis on CT findings.

Conclusions

At birth, a diameter of the piriform aperture at the level of the inferior nasal meatus of ≥5 mm on CT may indicate a good chance of success using conservative treatment.
