However, this surgical approach is not feasible when the glottis and subglottis are involved or in patients with a poor general condition and tracheal stents are a plausible means of providing a permanent or temporary airway opening. Objectives: Evaluate the features and the results of patients with Montgomery T-tube in tracheal stenosis. Methods: Fifteen patients with Myer-Cotton grades 2-3 circular cicatricial tracheal stenosis who received a Montgomery T-tube between 2002-2011 were analyzed in terms of age, gender, etiology, duration of intubation, location and size of the stenotic segment on computed tomography(CT), follow-up time with the T-tube, the complications that occurred after T-tube removed and additional tracheal surgery. Conclusion: A T-tube can be applied in tracheal stenosis at the first treatment before attempting surgery. The patients should be closely followed-up due to the possibility of re-stenosis and other complications.展开更多
