Treatment options

Evidence-based approaches to managing this condition.

First-line treatments

1

Choanal atresia surgical repair

Endoscopic or transnasal surgical approach to create an opening through the blocked nasal passage. This is a critical first-line intervention to restore airway patency and enable normal breathing, especially in bilateral cases affecting infants.

2

Combination drug regimen with regular assessment

Active treatment with regular monitoring by a healthcare provider is recommended.

medication
3

Multidisciplinary congenital anomaly surveillance

Regular comprehensive monitoring by ENT specialists, ophthalmologists, geneticists, and developmental pediatricians. Imaging studies track choanal patency and assess microphthalmia progression over time.

monitoring

Additional treatment options

Nasopharyngeal airway stent placement

Temporary or permanent stent placement maintains nasal airway patency following surgical repair or when surgical intervention is not immediately feasible. Requires regular monitoring for migration or obstruction.

procedure

Craniofacial reconstructive surgery

Comprehensive reconstructive procedures addressing nasal and facial structural abnormalities, including potential prosthetic nose creation for arrhinia. Typically staged across developmental periods as the child grows.
