Post dilation (1 of 4)
Six months after dilation of idiopathic (inflammatory) subglottic stenosis, the patient has noted only slight deterioration, and breathing ability remains acceptable to her.

Closer view (2 of 4)
At closer range, the inflammatory component appears more evident.

Rich vascular pattern (3 of 4)
The rich vascular pattern accompanying the lesion is seen better and is a visual finding of inflammation.

"Sharing" the airway (4 of 4)
Here, the scope has been passed through the area of maximal narrowing and the patient becomes acutely aware of greater difficulty breathing. "Sharing the airway" is a way of 'measuring' it functionally. Note again the congested capillaries.

Idiopathic inflammatory subglottic stenosis (1 of 3)
This patient is about to receive a triamcinolone (steroid) injection into her idiopathic inflammatory subglottic stenosis, while sitting in a chair under topical anesthesia. Dotted circle is for reference with Photo 2.

Priot to injection (2 of 3)
A needle has been passed through anterior neck skin and its tip rests out of sight, submucosally just inferior to the anterior cricoid ring. Note that the milky white medication has been infused submucosally within the dotted ring.

Injection (3 of 3)
Here, the 27-gauge needle traverses the trachea in order to inject the posterior tracheal wall. The submucosal white medication appears at the *.
