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

Recently the incidence of tracheal stenosis is gradually increasing. Tracheal stenosis is an irreversible, progressive disease and the only effective treatment is surgical removal of stenosis tissue to restore normal tracheal lumen. From January 2008 to April 2011, 6 patients with thoracic tracheal stenosis in our department underwent tracheotomy and T-tube stent implantation by endoscope with good results.展开更多
