This book provides step-by-step illustrated descriptions of diverse vocal fold injection techniques, including some not previously described. The aim is to provide laryngologists in general, and especially those who are less experienced, with the detailed understanding and guidance needed in order to achieve optimal outcomes. Highly experienced experts describe approaches via the transoral, transnasal, and transcutaneous routes and offer guidance on indications, injection materials, pre- and postoperative care, and the management of complications. Special considerations that must be borne in mind when employing different vocal fold injection techniques, in different settings, are also carefully explained. In offering comprehensive, up-to-date information on this minimally invasive and cost-effective procedure, Vocal Fold Injection will be an essential aid for practitioners.
