Subglottic / Tracheal stenosis (1 of 4)
Inflammatory subglottic/tracheal stenosis, thought to be the result of an incomplete expression of Wegener's granulomatosis (no history of trauma).

Subglottic / Tracheal stenosis (2 of 4)
Close view, from vocal cord level.

Subglottic / Tracheal stenosis (3 of 4)
Close view, from just above vocal cords.

Subglottic / Tracheal stenosis (4 of 4)
Close view, showing the inflammatory nature of the stenosis.

Tracheal stenosis (1 of 3)
View from level of vocal cords shows residual lumen of airway at only ~35% of normal. The dotted circle shows how big the lumen should be.

Tracheal stenosis (2 of 3)
Closer view shows the characteristic appearance of mucosa and the inflammatory nature of the stenosis (pinkness).

Just below the tracheal stenosis (3 of 3)
After just passing through the stenotic area, distal trachea is normal in caliber and color.

Subglottic stenosis, before dilation (1 of 2)
This individual has undergone at least a dozen prior dilations, each of which provides dramatic relief from noisy breathing and exercise intolerance. Here the patient is halfway to needing re-dilation, due to the typical inflammatory stenosis that is seen. Compare with photo 2.

Subglottic stenosis, after dilation (2 of 2)
One week after one of this patient's dilations (with Kenalog injection and topical Mitomycin C), showing a dramatic widening of her airway; compare with photo 1. After a number of years, inflammatory lesions such as this sometimes "burn out," and the interval between dilations increases.

Subglottic stenosis (1 of 5)
Middle-aged woman with unexplained shortness of breath and noisy breathing, due to this idiopathic inflammatory and very high subglottic stenosis. The patient initially declined dilation due to her anxiety. She also had granularity of the nasal septum and a positive ANCA profile for Wegener’s granulomatosis.

Subglottic stenosis, worsened (2 of 5)
Five months later, the symptoms became intolerable, and the stenosis was noted to be slightly narrower and with a greater posterior component. The patient agreed to dilation.

Subglottic stenosis, worsened (3 of 5)
Same exam as photo 2; this close-up view shows more clearly the inflammatory nature of this stenosis.

Subglottic stenosis, after dilation (4 of 5)
Five days after outpatient dilation, triamcinolone injection, and topical mitomycin C application. The patient’s symptoms have vanished, the harsh inspiratory noise is no longer heard, and the size of the airway, though still not normal, is more than doubled. Compare with photo 2 of this series.

Subglottic stenosis, after dilation (5 of 5)
Same exam as photo 4, close-up view. Intensification of the inflammatory changes of this stenosis are expected so early after dilation. Compare size of the stenosis with photo 3 of this series.
