A case of congenital cartilaginous cricoid stenosis was reported and discussed on literatures.A 9-year-old girl was admitted because of stridor and dyspnea after birth. Clinical examinationsrevealed subglottic stenosis and Fallot's tetralcgy with atrial septal defect. After cardiacsurgery with tracheotomy, the patient was referred to ENT Department. With direct laryngosccpyand radiological examinations a hard stenosis was found at the level of the cricoidcartilage immediately below the normal vocal cords, leaving an airway posterioly with a diameterof 3mm in the sagittal plane. A midline incision was made from the tracheostoma to thecricoid cartilage, which was found to be solid homogeneous wedge-shaped bulky mass. Theinner surface of cricoid cartilage was reduced into the shape of normal subglottic lumen andcovered with the niucous membrane preserved as far as possible. In the new subglottic lumena silicon tube with a diameter of 7mm was retained as a stent and the incision was closedprimarily. The stent was extubated endoscopically and the tracheostoma was closed successfullyin three weeks without any respiratory distress. In literatures, 13 cases of cartilaginous cricoidstenosis were collected and the entity of the congenital cartilaginous cricoid stenosis was discussed on the basis of embryological studies of the larynx.
