Vocal Fold Paralysis
Paresis/paralysis can happen at any age, from birth to advanced age, in males and females, from a variety of causes. The effect on patients could vary greatly, depending on the patient’s use of his or her voice.
Vocal Fold Paralysis is the total interruption of nerve impulse, resulting in no vocal fold movement.
Vocal Fold Paresis is the partial interruption of nerve impulse, resulting in weak or abnormal motion of laryngeal muscles.
|1.||Damage or trauma to the recurrent laryngeal nerve and superior laryngeal nerve during surgery||Birth trauma|
|2.||Can regenerate and re-establish movement||Neurological Disorders
|3.||Can be due to neurological conditions, viral infections, head/neck injuries, tumors, disease, surgery, stroke||Tracheosophageal fistula has been associated in 12% of children with vocal fold paralysos (Syed, 2014)|
An individual with Vocal Fold Paralysis would be seen by an Otolaryngologist (ENT). The ENT will be able to diagnose vocal fold paralysis.
Therapies I would recommend:
Half Swallow, Boom: When the patient swallows, the larynx is at maximum closure as physiologically possible. “Boom” is a brief word composed of voiced sounds that can all be produced as the air is released from the constricted larynx. There is then back pressure on the larynx (like blowing through a straw). Head turning assists with laryngeal closure
Resonance Treatment: The patient’s increased awareness of easy onset helps facilitate a more appropriate manner of phonation.
Pushing Approach: Helpful for patients with traumatic injury to the vocal folds, unilateral vocal cord paralysis, generalized fatigue. Increases strength in vocal fold adduction
