Subglottic stenosis is narrowing just below the vocal cords, in the lowest part of the larynx and immediately above the first tracheal ring. Examples of causes include scarring from a breathing tube used during a long ICU stay, Wegener’s Granulomatosis (aka Granulomatosis with polyangiitis), and idiopathic subglottic stenosis (aka limited Wegener’s Granulomatosis).

Using Your EARS to Understand Airway Narrowing
A narrowing anywhere in the breathing “pipe” that leads to the lungs causes shortness of breath, typically with harsh inspiratory noise on exertion. Such a narrowing can follow injury, intubation, cancer treatment, auto-immune disorders, etc.
It is possible to gain an immediate understanding of the magnitude of the airway narrowing within minutes by using a simple test “graded” with one’s ears. The severity of the problem can be understood before any examination or X-ray evaluation.
