Four cases of benign post-intubation tracheal stenosis studied before and 3 months after dilatation and insertion of a Dumon tracheal stent are described. The role of traditional techniques (chest radiograph, endoscopy, spirometry) has been evaluated together with nuclear magnetic resonance (NMR) and radionuclide techniques. NMR localizes the site of tracheal stenosis, its distance from vocal cords and sternal manubrium, the caliber and the length of stenosis. Ventilation lung scintigraphy has been employed to describe pathophysiological modifications of airflow inside the stenosis. Ventilation and perfusion lung scintigraphy also allows to evaluate the effects of the presence of stenosis on pulmonary distribution of ventilation and perfusion.
