Abstract
Muscle tension dysphonia (MTD) is a voice disorder characterized by excessive tension of the laryngeal muscles during phonation. Voice therapy is the gold standard of treatment for MTD. However, patients with MTD do not always respond to voice therapy. Multidisciplinary approaches have been attempted to treat intractable MTD such as lidocaine instillation, lidocaine injection to recurrent laryngeal nerve, botox injection and excision of false ventricle using CO2 laser. Recently, injection laryngoplasty is suggested that assists in more efficient phonation and voice therapy to MTD patients. A patient with intractable MTD underwent lidocaine injection and injection laryngoplasty showed improved voice quality and remained stable until postoperative 3 months without any complications.
