Objective: Congenital tracheal stenosis (CTS) is a very infrequent malformation. Till recently, the outlook for these patients was dismal because medical management was the only way of treatment. Surgical and endoscopical techniques developed in the last years have improved the prognosis. We review the short- and long-term outcomes of a single institution experience in the management of children with CTS, comparing different treatment modalities. Methods: Between 1991 and 2004, 19 cases of CTS have been managed in our Unit. Respiratory symptoms varied from mild stridor on exertion to severe distress. Bronchoscopy was performed for diagnostic purposes in all cases; other imaging techniques (computed tomography (CT), magnetic resonance imaging (MRI), bronchography, angiography, doppler-ultrasound) were performed on an individual basis. According to clinical and endoscopical features, patients were classified into three groups. The following data have been studied in each case: sex, age at diagnosis and treatment, anatomical type, associated anomalies, treatment modality, complications, outcome and time of follow-up. Results: Ten boys and nine girls have been included in this study. Age at diagnosis ranged from 3 days to 7 years (median, 4 months) and 84% of cases showed associated anomalies. Five patients presented mild or no symptoms and have been managed expectantly. The other 14 cases were operated on because of persistent or severe clinical symptoms. The following procedures were performed: slide tracheoplasty (n = 7), costal cartilage tracheoplasty (n = 5), tracheal resection and reconstruction (n = 3), endoscopical dilatation (n = 3), stent placement (n = 1), and laser resection (n = 1). Three patients required two or more procedures and surgical survival rate is 78%. Overall mortality in the series is 21% and all survivors (15 patients) are asymptomatic or show mild symptoms with respiratory infections only. Follow-up is complete, ranging from 8 months to 12.3 years (mean, 5 years). Conclusions: Bronchoscopy is our preferred diagnostic tool. Selection of the type of treatment depends on the patient's clinical status and the anatomical pattern of the stenosis. In symptomatic cases with short-segment stenosis (<30% of total tracheal length), we prefer tracheal resection with end-to-end anastomosis; for long-segment stenosis (>30%), slide tracheoplasty is our procedure of choice.
