Post intubation tracheal stenosis (PI) was recognized in 1880, after prolonged endotracheal intubation in 4 patients with upper airway obstruction.The most common causes of acquired tracheal stenosis are endotracheal intubation and tracheostomy. Tracheal stenosis is a surgical problem managed non operatively by bronchoscopic dilation, endoluminal treatment with lasers, and stenting. Bronchoscopic management have a good success rate. PI and post tracheostomy stenosis (PT) are recognized with an 4.9 cases per million per year in the general population. Prolonged intubation can result in tracheal stenosis at various levels within the trachea.Tracheal stenosis occurs at the endotracheal tube cuff site in one third of the reported PI cases [9] and appears as a web-like fibrous. The mainly postulated cause is loss of regional blood flow.This injury begins within the first hours of intubation, and healing of the damaged areas within 3 to 6 weeks. Large volume, low pressure cuffs has reduced the occurrence of cuff injury.Patients in the ICU are common to have respiratory involvement, with 30-50% of the admissions requiring the use of mechanical ventilation.Flexible bronchoscopy has become the procedure of choice in most examinations of the tracheobronchial tree.The incidence of PI tracheal stenosis ranges from 6-21% and following tracheostomy ranges from 0.6-21%.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| post intubation tracheal stenosis patients | Experimental | all ICU patients who were mechanically ventilated will be assessed for the possibility of presence of tracheal stenosis using spirometery and dyspnea will be assessed using (mMRC) score, chest X-ray to assess the location of tracheal stenosis and finally flexible bronchoscopy to confirm the presence of stenosis and identify the proper management. |
