Spasmodic dysphonia, or laryngeal dystonia, is a neurologic condition affecting the vocal cords. It can manifest as involuntary closure of the vocal cords during vowel sounds, or involuntary opening of the vocal cords during voiceless consonants. Symptoms can start as early as adolescence and are worse with stress and improved by relaxation, alcohol, and depressant drugs. In addition to the larynx and vocal cords, dystonia can affect muscle groups throughout the body. Examples include hand dystonia (writer's cramp), cervical dystonia (torticollis), and oromandibular dystonia (jaw and tongue).
Treatment of spasmodic dysphonia is targeted at relieving involuntary spasm, and the primary treatment at the present time is laryngeal Botox injection. The vocal cords are injected with minute doses of Botulinum toxin, slightly weakening the muscles. This leads to an improvement of the voice lasting an average of 3 months at a time. Injections are typically performed by otolaryngologists (ear, nose, and throat specialists) with interest in the voice, although some neurologists perform the procedure with the help of an otolaryngology physician.
Newport Voice and Swallowing, the medical practice of Steven Feinberg MD, performs laryngeal Botox injections using electromyography for proper injection placement. We also perform Botox injection for cervical and oromandibular dystonia.
