抄録

Two cases (sisters aged four and five) with congenital choanal atresia were reconstructed by endoscopic transnasal surgery using laser. Both choanal obstructions were of bony plate in the right nasal cavity. After opening the atresia, we inserted a silastic tube into the nasal cavity. One case developed polypoid tissue around the tube after two months, necessitating extraction of the tube and removal of the granulation, after which the tube was reinserted and left in place for six months. In the other case, the silastic tube remained in place for six months without restenosis. One year after surgery, there was no recurrence of stenosis. Endoscopic transnasal surgery is minimally invasive and an effective method of treating choanal atresia in children.
