Abstract
Injection laryngoplasty can be performed easily under fiberoptic endoscopy. We use a flexible operative endoscope with a 2 mm working channel, into which a flexible needle is inserted. This needle is protected by a catheter and it is connected to a high-pressure gun, into which the injectable material is introduced. In our experience, this technique is useful for the laryngeal injection of resorbable or partially resorbable materials such as hyaluronic acid, autologous fat, and calcium hydroxylapatite. The main indications of this technique are vocal fold medialization/augmentation in cases of glottic insufficiency caused by unilateral vocal fold paralysis; atrophic vocal folds with or without vergeture (it is particularly indicated in presbyphonia); sequelae of cordectomies type III, IV, and V; and sequelae of partial laryngectomy. We can also obtain a decrease of the vocal fold volume (in Reinke’s edema, hypertrophic vocalis muscle, androphonia) by injecting triamcinolone.
The procedure is performed under local anesthesia, which allows to monitor the effect of injection laryngoplasty on glottic closure and on patient’s voice.
