Abstract
Five cases of tracheal stenosis caused by tracheostomy and endotracheal intubation are described. The authors always prepare silicone tubes and cut them appropriately to fit the tracheal stenosis. It is easier and more effective to treat the various parts of the tracheal stenosis separately. The period of intubation was from 3 months to 4.5 years. The tube must be carefully removed after hospitalization.
