What is posterior glottic stenosis?
Posterior Glottic Stenosis (PGS) is a life-threatening condition in which the vocal folds are fixed in a midline position. This results in a severely narrowed glottic airway with limited vocal fold abduction and subsequent ventilatory collapse.
What are the grades of subglottic stenosis?
The most common grading for the diagnosis of subglottic stenosis is the Meyer-Cotton grading scale. Grade 1 stenosis is lumen obstruction less than 50%. Grade 2 stenosis is lumen obstruction between 51% and 70%. Grade 3 stenosis is lumen obstruction between 71% and 99%.
