Abstract
|
|
|
Choanal atresia is the congenital failure of one or both posterior nasal apertures to
communicate with the nasopharynx. Coexisting congenital anomalies are percents 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
stealing 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 17 days
old female, which was treated by transpalatal approach and report the case with review
of literatures.
