Injection Laryngoplasty for type 1 laryngeal cleft is done with first identifying the deep cleft by palpation of the interarytenoid notch. Once a confirmation is made the larynx is suspended with a laryngoscope. Radiesse voice gel is then primed in a laryngeal needle and the needle is placed at the apex of the cleft. The needle is then pushed to palpate the cricoid cartilage with the bevel of the needle pointing towards the esophageal surface. The needle is then slightly retracted and about 0.2 ml of voice gel is injected. Care is taken not to make multiple punctures and the subglottisis watched so that the injection does not inadvertently go into subglottis.
