The operative methods for the choanal atresia or stenosis are transseptal, transnasal, transpalatal and transmaxillary approaches. Among them, endoscopic transnasal approach provides excellent visualization and little age limitation. The use of CO2 laser in the management of choanal atresia enables the accurate incision and vaporization. We experienced a case of acquired bilateral choanal stenosis which developed after external irradiation for nasopharyngeal carcinoma. She presented with the symptoms of slowly progressive bilateral nasal obstruction and persistent nasal discharge for the past three years prior to visiting hospital. We successfully managed her by endoscopic transnasal repair with CO2 laser and found this technique to safe and simple.
