We present a series of 8 patients under the age of one who successfully underwent EPCSCG, with 7/8 patients avoiding tracheostomy entirely. Of these patients, the indication for EPCSCG was isolated bilateral vocal fold immobility (6/8), bilateral vocal fold immobility with subglottic stenosis (1/8), and isolated subglottic stenosis (1/8). EPCSCG can be safely applied to select patients less than one year of age.
