Neonatal nasal obstruction.

Area of Science:

• Neonatal Medicine
• Otolaryngology
• Pediatric Respiratory Medicine

Background:

• Congenital nasal obstruction poses significant respiratory risks for newborns, who are obligate nasal breathers.
• Causes range from anatomical defects and masses to inflammatory and infectious conditions.

Purpose of the Study:

• To provide updated clinical information on congenital nasal obstruction for neonatal care teams.
• To review the diverse etiologies and management strategies for neonatal respiratory distress due to nasal obstruction.

Main Methods:

• A comprehensive literature review was conducted using PubMed.
• Relevant headings and sub-headings were searched, with cross-referencing of studies.

Main Results:

• Inflammatory conditions, including neonatal rhinitis, are the most common causes.
• Less frequent but severe causes include choanal atresia, midnasal stenosis, and pyriform aperture stenosis.
• Diagnosis often involves nasal endoscopy and imaging (e.g., CT); management is etiology- and severity-dependent.

Conclusions:

• Congenital nasal obstruction is a critical cause of neonatal respiratory distress.
• Effective management necessitates a deep understanding of nasal anatomy, physiology, pathology, and varied treatment approaches.
