Transnasal endoscopic management of choanal atresia.

Since 1755, when Roederer first described choanal atresia, more than 350 papers have been published dealing with the various aspects of this entity. Many surgical techniques have been used to treat the malformation, each with its advantages and disadvantages. Endoscopic transnasal repair of choanal atresia provides excellent visualization and enables accurate surgery to be performed on patients of all ages and even on newborn infants. Described are two newborn infants, one with bilateral choanal atresia and the other with bilateral choanal stenosis, successfully treated by endoscopic transnasal repair, with a 12 month follow-up. The technique of endoscopic choanal repair is described, emphasizing it as a highly successful, short and safe procedure with swift recovery and short hospitalization.
