The Causes of Vocal Paresis

According to information from the University of California at Davis’ Department of Otolaryngology, the most common causes of vocal paresis include surgical trauma and neurological disorders.

However, the onset doesn’t always relate to medical complications or frequently credited overuse of the voice.

Emotional events could contribute to diminishing vocal strength and control as well.

The most reliable method of diagnosing vocal paresis is by a process known as laryngeal electromyography.

The laryngologist inserts a small needle (similar to acupuncture) into the muscle that controls movement of the vocal fold to measure its neural activity.

If this is abnormal, there is a good chance vocal paresis is the result.

Laryngeal electromyography also helps in determining the singer’s recovery prognosis, if the vocal fold will regain normal function and allows for surgical intervention, if necessary.

In many cases, the suffering vocal fold could regain movement in a year’s time with rest and rehabilitation, without surgery.
