INTRODUCTION. The placement of a T-tube is a safe alternative in patients with laryngotracheal or tracheal ischemic stenosis for those who have not been indicated resection or anastomosis. The objective of the present study was to analyze the result obtained with this prosthesis. METHODS. A prospective and descriptive study of 69 consecutive patients that were placed a T-tube between November 1991 and September 2002 was conducted. The studied variables were age, sex, extension of stenosis, resection practice, and its localization (subglotic or tracheal). The response variables were the complications and relapses. The statistical analysis included univariate (Fisher's test and Chi square test) and multivariate techniques (logistic regression model). RESULTS. The percentage of complications was 33.3 % and the most frequent were tracheal granulomas, local infection, late cervical fistula and tube obstruction. Average age (p = 0.045) and the tracheal localization of the lesion (p = 0.035) were associated with surgery failure. The influence of average age (p = 0.036) on the appearance of relapses was proved by multivariate analysis. Finally, 55 patients (80.9 %) had good or satisfactory results. CONCLUSIONS. Montgomery's T-tube was useful when resection and termino-terminal anastomosis were not indicated. Satisfactory results of its use as a unique treatment may be expected in a significant group of patients.
