Overview
Pyriform aperture stenosis is a congenital malformation resulting in a narrowed pyriform aperture and subsequent nasal obstruction.
History

Pathophysiology
Relevant Anatomy
Key anatomy includes the structures of the nasal cavity and midface.

Disease Etiology
Genetics
Diagnosis
Patient History
It is important to take a focused history related to any airway or feeding symptoms, including:
- Prolonged feeding times
- Needing frequent breaks during feeds
- Cyanosis or increased respiratory effort, especially with feeding
- BRUE's
- Difficulty placing nasogastric tubes
- Family history of genetic conditions with anatomic malformations
Physical Examination
Imaging
CT maxillofacial will demonstrate decreased pyriform aperture diameter, especially on axial view. A pyriform aperture width of less than 11 mm is diagnostic for pyriform aperture stenosis.[1]
