Summary
Two neonates with nasal obstruction due to congenital nasal pyriform aperture stenosis also had a single central incisor. These findings are minimal manifestations of holoprosencephaly, requiring multidisciplinary management.
Area of Science:
- Neonatal Medicine
- Pediatric Surgery
- Medical Genetics
Background:
- Congenital nasal pyriform aperture stenosis is a rare cause of neonatal nasal obstruction.
- Midline developmental anomalies can indicate underlying genetic syndromes.
- Holoprosencephaly spectrum disorders range from severe brain malformations to subtle midline defects.
Observation:
- Two neonates presented with nasal obstruction attributed to anterior choanal stenosis.
- Computed tomography (CT) imaging revealed an associated single maxillary central incisor in both neonates.
- These midline anomalies were recognized as potential microforms of holoprosencephaly.
Findings:
- The neonates exhibited a combination of nasal obstruction and a single central incisor.
- These clinical features, though seemingly isolated, were linked to the spectrum of holoprosencephaly.
- Diagnostic workup confirmed the association between choanal stenosis, single incisor, and potential holoprosencephaly.
Implications:
- Early recognition of these microforms is crucial for timely diagnosis of holoprosencephaly.
- Multidisciplinary management involving neonatology, surgery, and genetics is essential for optimal outcomes.
- This case highlights the importance of evaluating midline anomalies in neonates for broader developmental implications.
