Vocal tremor causes a wavering and unsteady voice. In extreme cases, the voice can be interrupted. Involuntary movements in the larynx, vocal cords, or throat cause vocal tremors. The condition may sometimes overlap with spasmodic dysphonia.
To diagnose a vocal tremor, one of our fellowship-trained laryngologists will review your medical history and listen carefully to your voice. Using fiber-optic technology and a stroboscope, vocal tremor can be diagnosed during a physical exam.
Videostroboscopy provides a magnified, slow-motion view of your vocal cords, which allows laryngologists to better diagnose voice problems over traditional endoscopic methods.
The procedure involves placing a telescope-like device on the tongue or passing a flexible version through the nose. The scope shines a strobe light on the vocal cords while you make sounds. The videotaped exam, which is reviewed with you, offers specific details regarding the vocal cord vibratory pattern, and allows the laryngologist to observe specific abnormalities of the vocal cords.
Laryngologists consider stroboscopy to be essential for state-of-the-art management of voice disorders.
While there is no cure for voice tremor, there are treatments that can help with the symptoms. Some oral medications and botulinum toxin injections can reduce vocal tremor by weakening the vocal cord muscles. Voice therapy may also help you speak more clearly and with improved vocal stamina.
