신생아의 양측성 후비공 폐쇄증 1례

Choanal atresia is the congenital failure of one or both posterior nasal apertures to communicate with the nasopharynx. Coexisting congenital anomalies are persent in 20% to 50% of patients in most series. Bilateral choanal atresia almost always presents in the newborn as respiratory distress, suckling difficulty and cyanosis relieved by crying. Some babies can compensate this dangerous problem by rapidly learning mouth breathing. Bilateral choanal atresia in newborns and infants carries significant morbidity and mortality, therefore, prompt correction is required. In the operations employed, the following four different approaches are used : transnasal, transseptal, transantral and, most commonly, transpalatal. Transpalatal approach affords superior visualization, a shorter stenting period, and a higher overall success rate, making it more useful for revision surgery.

The authors recently experienced a case of bilateral choanal atresia in 17days old female, which was treated by transpalatal approach and report the case with review of liferatures.
