A Case of Bilateral Choanal Atresia without Stenting / 대한이비인후과학회지

ABSTRACT

Bilateral choanal atresia is a rare disorder characterized by bilateral obstruction of the posterior end of the nasal cavity. It can be present in isolation or associated with multiple disorders such as coloboma, heart defect, choanal atresia, retarded growth, genital hypoplasia, ear abnormalities (CHARGE) syndrome. Because congenital bilateral choanal atresia presents as respiratory distress at birth, immediate diagnosis and adequate treatment is required. Traditionally, using stents was a part of the postoperative treatment to provide a low rate of restenosis but recently it is controversial. Currently nasal endoscopic approach is mainly used with or without stenting. We report a case of CHARGE syndrome with bilateral choanal atresia treated by transnasal endoscopic approach without stenting.
