Congenital choanal atresia is a relatively rare abnormality characterized by unilateral or bilateral lack of the posterior nasal cavity. We report a case of congenital choanal stricture undergoing endoscopic transnasal repair. An 18-day-old male had bilateral membranous stricture of the choanae. In the first and second operations, endoscopic intransnasal surgery cut bilateral membramous folds of the choanal with a YAG-laser. Choanal restenosis followed each operation. In the third operation, the posterior portion of the vormer was removed, and the raw bony area was covered by folding the mucosal flap of the nasal septum. No restenosis of the choanal has been observed 6 mouths after the third operation. We assume that we effective by prevent of choanal restructuring on the third try.
