3. Procedure

1. The provider prepares the patient and administers anesthesia.
2. A flexible fiberoptic laryngoscope is inserted through the nose to visualize the laryngeal and hypopharyngeal structures.
3. The provider injects a filler material, such as calcium hydroxylapatite or hyaluronic acid, into one side of the vocal folds using a percutaneous or transoral technique.
4. The provider examines the larynx and related structures again to ensure proper augmentation and then removes the laryngoscope.
