Abstract

Congenital choanal atresia is an uncommon anomaly. In most reported series it has an incidence of 1 in 7,000 or 80,000 births with female preponderance. Approximately 90% of cases are reported as having unilateral bony type congenital atresia. Bilateral congenital choanal atresia cause acute life-threatening respiratory obstruction in newborns, whereas unilateral atresia alone does not cause significant airway obstruction. Rarely an infant may compensate by rapidly learning mouth breathing and the diagnosis may escape detection for months or even years. A variety of techniques are available to correct this problem, but none is entirely satisfactory. The authors recently experienced a case of unilateral membranous type congenital choanal atresia which was treated by KTP/532 laser and report the case with review of literatures.
