How does unilateral vocal fold paralysis affect a person?
In unilateral paralysis, the vocal folds are unable to close, which causes voice and swallowing problems. The voice is hoarse, breathy and soft, and speaking above background noise is a challenge. The pitch of the voice usually becomes difficult to control.
What is unilateral adductor vocal fold paralysis?
Unilateral vocal fold paralysis (UVFP) occurs from a dysfunction of the recurrent laryngeal or vagus nerve innervating the larynx. It causes a characteristic breathy voice often accompanied by swallowing disabilty, a weak cough, and the sensation of shortness of breath. This is a common cause of neurogenic hoarseness.
What is unilateral paralysis called?
1. Both vocal cords do not move, called bilateral vocal cord paralysis (BVCP) 2. Only one vocal cord does not move, called unilateral vocal cord paralysis (UVCP) Even though the two are related, the causes and management for each condition are different.
What is the most common cause of unilateral vocal cord paralysis?
The most common cause of unilateral vocal cord paralysis in our study is surgery and thyroidectomy continues to be the single most common surgical procedure responsible for unilateral vocal cord paralysis.
What is injection Medialization?
Injection medialization laryngoplasty is a procedure that provides support to a vocal fold that lacks either the bulk (such as in vocal fold bowing) or the mobility (such as in paralysis) it once had.
What does Medialization mean?
Definition. Medialization laryngoplasty is a procedure that provides support to a vocal fold that lacks either the bulk, the mobility or both, that it once had. Most commonly it is used to try and correct a neurologic injury or problem that prevents full closure of the vocal fold or folds.
What is unilateral diaphragmatic paralysis?
Unilateral diaphragmatic paralysis is a condition in which either the right or left side of the diaphragm loses the ability to contract to allow proper inspiration. This can result from muscular issues in the diaphragm or loss of innervation from the phrenic nerve to the hemidiaphragm.
What do vestibular folds do?
The vestibular folds of the larynx play a significant role in the maintenance of the laryngeal functions of breathing and preventing food and drink from entering the airway during swallowing. They aid phonation (speech) by suppressing dysphonia.
What is vocal fold Medialization?
What Does Vocal Fold Medialization Involve? During this procedure, the paralyzed vocal fold is pushed to the middle so that the functioning vocal fold can close as necessary for normal voice and swallowing.
How long does Prolaryn last?
PROLARYN GEL is a temporary implant and resorbs within a period of 3-6 months.
What are the treatment options for unilateral vocal fold paralysis?

What are the treatment options for unilateral paralysis of the neck?
You may need medical treatment for unilateral paralysis. This might include muscle-nerve transplant or surgery to move the paralyzed fold toward the middle. You might also have something injected into the fold to make it larger. This allows the other fold to move closer to it and may help your voice.
What is the concept of Medialization laryngoplasty?
The concept of medialization laryngoplasty is to medialize the paralyzed vocal fold from an external approach and work through the thyroid cartilage. A small window is incised and removed from the thyroid cartilage, and an implant is placed through the window to medialize the paralyzed vocal fold. See the images below.
What is the role of voice therapy in the treatment of vocal fold?
In the setting of vocal fold paralysis, voice therapy is generally not a long-term treatment modality; substantive results are usually obtained in 2-3 sessions. Postoperative voice therapy used in combination with surgery is often used; however, 1-2 sessions of voice therapy prior to surgical treatment of UVFP can often be efficacious.
