This video demonstrates a steroid injection in an awake patient for the treatment of idiopathic subglottic stenosis. The patient is first anesthetized with topical 2% lidocaine over the larynx and 1% lidocaine with epinephrine percutaneously over the cricoid cartilage. An endoscope is passed transnasally and positioned just below the vocal folds. A 23 gauge needle is then passed through the cricothyroid membrane, and Kenalog is circumferentially injected submucosally taking care not to reduce the caliber size of the airway.
