New Paper Published by Dr. Chang on Spasmodic Dysphonia Treatment in the US

In the May 2009 edition of ENT Journal, Dr. Chang has published a paper titled "A Survey of Current Practices of Physicians Who Treat Adductor Spasmodic Dysphonia in the US." The paper was published online instead of the print magazine and can be read here for free after registration.

The paper reports on a variety of factors considered when treating patients with adductor spasmodic dysphonia including surgery (what kind), botox type (A or B or both), how much botox, what concentration of botox, whether botox that has been frozen is used, etc. Interestingly, though most physicians treat spasmodic dysphonia with botulinum toxin type A, there is great variation in the concentration and amount of botox utilized.

Dr. Chang treats patients with Spasmodic Dysphonia with botox injection every Friday afternoon.

New ADductor Spasmodic Dysphonia Audio Samples Posted

A patient with a very mild case of ADductor spasmodic dysphonia speaking a variety of phrases has been posted. The nice thing with this case is that only when saying certain "voice-weighted" phrases does the loss of vocal fluency become most apparent. The spasmodic dysphonia can be made less apparent when speaking "voiceless-weighted" phrases. Click here to hear the various audio clips.

As an FYI, the voice-weighted phrases which accentuate ADductor spasmodic dysphonia are as follows:
• Counting from 80 to 89
• "We mow our lawn all year."
• "We eat eels every day."
• "A dog dug a new bone."
• "Where were you one year ago?"
• "We rode along Rhode Island Avenue."
• "Eeee eee eee."

These voiceless-weighted phrases are MUCH easier to say for patients with ADductor spasmodic dysphonia:
• Counting from 60 to 69
• "Peter will keep at the peak."
• "We eat eels every day."
• "When he comes home, we'll feed him."
• "Tap the tip of the cap, please."
• "Keep Tom at the party."
• "See see see."
