In unilateral choanal atresia only one side of the nasal passage is blocked by bone or soft tissue. Learn what happens during surgery and how to take care of your child at home.

Key points

  • In unilateral choanal atresia, one nasal passage is blocked by bone or soft tissue. Air can pass through the other side of the nose.
  • During surgery, the nasal passage is opened. A small plastic tube called a nasal stent is placed in the nostril to keep the nasal passage open while it is healing.
  • A nurse will show you how to put nose drops in the nostril that has the stent in it.
  • Nasal stents are usually left in the nasal passage for about three months. When your child is ready, the stent will be removed in the hospital under a general anaesthetic.
