Laryngeal stenosis that has evolved towards the total closure of light at the level of the subglottis.
The patient suffers a post-intubation rash with damage to the laryngeal cartilages.
It develops a subglottic stenosis that, when it becomes symptomatic or critical, receives the relief of the tracheostomy at the hands of the surgeon. However, this “defunctionalization” of the larynx is what precedes its complete closure.
When it occurs at a lower level and affects the initial trachea, it constitutes the “blind trachea“.
