Laser beam in treating congenital choanal atresia in three patients.

We present the results of 3 patients with congenital unilateral choanal atresia who were treated surgically at our department. We report a method of surgical approach for repair of choanal atresia. A transpalatal procedure offers an approach which is straightforward. The use of carbon dioxide or Nd:YAG laser seemed better for recurrent cases. A tube stent should be placed for at least 6 weeks postoperatively.
