Congenital bilateral choanal atresia.

Eight neonatal patients with bilateral congenital choanal atresia were treated by endonasal perforation with a curved trocar. In two of these the atresia plate was perforated under direct vision using a 0 degree Hopkins rod endoscope. A stenting technique is described, the aim of which is to provide good fixation and easy postoperative nursing care. Of the cases, seven did not require further treatment. A single case required further dilatation on one side. The trans-nasal endoscopic technique and the described method of stenting is a safe, quick and efficient procedure for the correction of choanal atresia in neonates. A familial tendency is described in seven of the eight cases.
