A newer term for the auto-immune disorder previously called Wegener’s Granulomatosis.

Airway stenosis (1 of 5)

Marked inflammatory narrowing in the immediate subglottis. Within the ring of arrows is the inflamed, reddened tissue, which is narrowing the airway into the shape of a slit. This man needs to be active for his work, but notices shortness of breath and noisy breathing with exertion.

Airway stenosis, after dilation (2 of 5)

Nine days after a dilation procedure, with local steroid injection and painting with Mitomycin C. The airway has widened, so that it is more oval-shaped and less slit-like. Compare with photo 1. Although a degree of stenosis remains, symptoms have subsided dramatically. For reference, asterisks mark the same points in the subglottis in this photo and the next photo.

Airway stenosis, after dilation (3 of 5)

Same exam, looking beyond the immediate subglottis. There is an inflammatory response that involves several centimeters of the upper trachea. Inflammatory areas often “trap” mucus, as seen here.

Airway stenosis, before another dilation (4 of 5)

Now five months after the dilation procedure mentioned in photos 2 and 3. The patient has been receiving systemic treatment with methotrexate and prednisone. General appearance of the inflammation has decreased. In spite of this, as expected, the stenosis has persisted (dotted oval shows the estimated caliber or width of a normal airway) and symptoms have gradually increased. Thus, another dilation was scheduled for the next day.

Airway stenosis, after another dilation (5 of 5)

A week after photo 4, following the most recent dilation. There is expected immediate postoperative inflammation and an increase in the airway’s caliber or width by an estimated 30% (dotted oval again shows the estimated caliber or width of a normal airway; compare with photo 4). Symptoms are again abolished.
