How is choanal atresia diagnosed?

In most cases, bilateral choanal atresia is diagnosed when newborns are still in the hospital. If your healthcare provider suspects that your baby has choanal atresia, they may perform some tests, including:

• A CT (computed tomography) scan. More detailed than an X-ray, this imaging test takes thousands of pictures and stitches them together for a comprehensive, 3-D image.
• Nasal endoscopy. Your healthcare provider will insert a thin tube with a small camera attached into your baby’s nose to get a better look at the nasal structures.
