About tracheal stenosis

Cause of tracheal stenosis

Airway stenosis can be congenital or acquired. Acquired stenosis is currently the most common form. An obstructed airway is most commonly due to sequelae following iatrogenic lesions caused by intubation and tracheostomy.

Excessively high cuff pressure exerted on the trachea produces circumferential mucosal necrosis, which heals by granulation tissue formation and wound contraction.
