Vocal Cord Paralysis

Vocal fold paralysis (also known as vocal cord paralysis) is a voice disorder that occurs when one or both of the vocal folds don't open or close properly. The vocal folds are two elastic bands of muscle tissue located in the larynx (voice box) directly above the trachea (windpipe). When you breathe, your vocal folds remain apart and when you swallow, they are tightly closed. When you use your voice, however, air from the lungs causes your vocal folds to vibrate between open and closed positions.

Disease Statistics :
Pre-operative assessment found asymptomatic compensated vocal cord paralysis in a patient who had previously had a stroke. Post-operative laryngoscopy revealed asymptomatic impaired vocal cord mobility in three patients (6%) all of whom recovered completely,six patients (12%) developed post-operative hoarseness of whom five have fully recovered and (2%) developed vocal cord paralysis which is permanent to date.

Treatment:
Voice therapy: Voice therapy sessions involve exercises or other activities to strengthen your vocal cords.
Surgery: Surgical treatments may be offered to improve your ability to speak and to swallow. Surgical options include Bulk injection, Vocal cord repositioning and Tracheotomy.

Research :
An integrated diagnostic and treatment program is necessary for patients with vocal cord paralysis. Possibility of malignancy should be excluded before marking idiopathic reason to vocal cord paralysis.
