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.

The patient is a 53 year-old female with history of idiopathic subglottic stenosis and long-standing right vocal fold scarring who had previously been treated endoscopically in the operating room and in the office with steroid injections. She returns to the operating room for scheduled endoscopic CO2 laser treatment, Depo-Medrol injection (not shown), balloon dilation, and Mitomycin C application (not shown).

Adductor spasmodic dysphonia is the most common form of laryngeal dystonia, causing inappropriate glottic closure and strangled choppy voice. This video demonstrates step by step, the standard treatment for adductor spasmodic dysphonia: bilateral, EMG-guided, percutaneous botulinum toxin injections to the TA-LCA (thyroarytenoid and lateral cricoarytenoid) muscles.
