Subglottic stenosis

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).
