Abstract:
Laryngeal cysts can be classified into saccular (24%) or ductal (75%) cysts. In infants who have undergone intubation, ductal cysts are occasionally seen in the subglottic region. These cysts are caused by irritation and obstruction of mucous gland ducts. A 20-month-old infant admitted to our department due to inspiratory stridor, wheezing, and dyspnea. She was born prematurely and had a past history of endotracheal intubation with ventilator of 9 days because of respiratory distress syndrome. At 31 days of age, she was intubated again for 5 days because of pneumonia. She had admitted our hospital repeatedly at 7, 8, 16, and 17 months because of inspiratory stridor, wheezing, cough and dyspnea and she was diagnosed as asthmatic bronchitis. But symptoms developed again, she readmitted. A lateral X-ray film of the neck and neck spiral CT revealed a 6x5 mm sized homogeneous mass in the posterior wall of the subglottic region causing airway obstruction. A laryngoscopy was performed and showed a 4x5 mm sized cystic mass in the subglottic region. Endoscopic resection was done by Nd : Yag laser. The postoperative course was satisfactory. Histologic examination showed a ductal cyst, lined with ciliated cuboidal epithelium. This subglottic ductal cyst was believed to be a late complication of endotracheal intubation.
