title: Bilateral choanal atresia; evaluation with scintigraphy: case report.
abstract: Bilateral choanal atresia is a rare congenital anomaly that may cause severe neonatal respiratory distress. The clinical presentation varies from immediate postnatal cyanosis and respiratory distress to nasal obstruction with an associated persistent mucoid discharge. The aim of this study was to evaluate the effect of bilateral choanal atresia preoperatively and postoperatively on nasal mucociliary clearance with the radioisotope method (using technetium-99m macroaggregated albumin). We present a 17-year-old girl with bilateral choanal atresia treated by transnasal endoscopic surgery. The patient was free of symptoms for three years postoperatively. Mucociliary activity was returned to normal images.
