I was just diagnosed after 3 years of almost no voice, with Abductor SD. I took a little test i found online and it seems it's harder for me to get out the adductor words. Was wondering if it is two different ways to give the shot? Doctor is a specialist and he did say it was the abductor type.
What's the difference in the two treatments... |

People with Adductor type of Spasmodic Dysphonia (AD/SD) are typically injected in the Thyroarytenoid muscle (TA) which is located in the accessed from the front of the throat. People with Abductor type of Spasmodic Dysphonia (AB/SD) are typical injected in the posteror cricoarytenoid muscle (PCA) which is located in the back of the voice box, i.e. larnyx. The Botox shot for AB/SD is more difficult because it is harder to accurately locate this tiny muscle. You mentioned the doctor is a "specialist". If the doctor treats a number of Spasmodic Dysphonia patients, he is a "specialist". If the doctor is simply an ear/nose/throat (ENT) type doctor, that is not enough of a specialist because SD is rare and they might see a person with SD every couple of years! I have attached an internet link to a video by Dr. Robert Bastian. Dr. Bastian heads up the Bastian Voice Institute in Downer's Grove IL and is Chairperson of the NSDA's Medical Advisory Board. Listen to that video and see what you think after that. Related link: http://www.youtube.com/watch?v=3m21wKQJwcU |

Hi Gayle,
Abductor is more difficult to treat because of it being in the back of the voice box. Recently at a symposium in Denver they said there is about a 60% success rate. You really do need an experienced doctor. If you are scoped the doctor will be able to tell which SD you have as ABductor the vocal cords spasm open causing a breathy voice, whereas ADductor the vocal cords spasm close causing voice breaks. This can be seen on the monitor when you are scoped. There is also the possibility that you could be mixed and have both. Irish |
