Detailed explanation-1: -Tracheal stenosis is the narrowing of the trachea, or windpipe, and bronchial stenosis is the narrowing of the bronchial tubes, which branch off the trachea into the lungs. Sometimes both airways are constricted, which is referred to as tracheobronchial stenosis.

Detailed explanation-2: -Tracheal stenosis is either a congenital or acquired disease. Congenital stenosis may be associated with congenital airway malformations such as tracheoesophageal fistula, hypoplastic lungs, and tracheomalacia. Congenital complete tracheal rings are also a cause of tracheal stenosis.
