Tracheal stenosis is a potentially life-threatening condition. Tracheostomy and endotracheal intubation remain the commonest causes of benign stenosis, despite improvements in design and management of tubes. Treatment of Post intubation tracheal stenosis (PITS) is still controversy as there is no international consensus on management of the same.


To describe our bronchoscopic interventional experience and the role of silicon stents in management of benign tracheal stenosis.

Methods and material:

A prospective observational study was conducted in our institute spanning over a period of one year from April 2021 to March 2022. All patient referred for treatment of PITS were taken into study. These patients will be followed up for a period of 6 months and results compiled.


Seventeen patients were included in our study. Sixteen were males and one female with mean age of 31 years. The presenting symptoms were cough, stridor and breathlessness. The average duration of intubation was 5 days. Mean duration from extubation to development of symptoms was 2 weeks. Two third of patients had complex tracheal stenosis. The most common etiology was road traffic accident followed organophosphorus poisoning. Out of 17 patients, 16 underwent silicon stent placement and one patient underwent serial balloon dilatation. Follow up results will be presented during the conference.


Though many studies prefer surgical repair as first choice for benign tracheal stenosis, our study has shown excellent results with silicon stent placement. We recommend a silicon stent placement for all complex stenosis cases.
