Abstract

The congenital posterior choanal atresia is an uncommon, but not rare, disorder that may threaten the newborn’s existence or give rise to chronic symptoms. As many as 50% of patients with choanal atresia have other associated anomalies. We experienced a case of congenital posterior choanal atresia without associated anomaly in 6 day old female baby. The patient was hospitalized due to the main symptoms of respiratory difficulty, cyanosis and mucoid rhinorrhea since birth. In physical examination, the patient showed mild cyanosis on perioral area and subcostal chest wall retraction. Initially, we induced an oral respiration and feeding by the application of McGovern’s nipple and oro-gastric tube as an emergency treatment. The diagnosis was confirmed by the skull X-ray films after instillation of contrast material (hypaque) and nasal bone CT scan. The operation was done by transnasal approach with the aid of operating microscope. Total operation was done three times during the 8 moths period due to the obstruction by the granulation tissue formation and the accidental removal of stent tube. She is now a 10 months old age and is in good condition. We report a case of bilateral choanal atresia treated with nasal stent insertion by transnasal approach.
