What is a vocal cord paresis?
Vocal fold (or cord) paresis and paralysis result from abnormal nerve input to the voice box muscles (laryngeal muscles). Paralysis is the total interruption of nerve impulse, resulting in no movement; paresis is the partial interruption of nerve impulse, resulting in weak or abnormal motion of laryngeal muscles.
What is unilateral paresis?
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 bilateral paresis?
In bilateral vocal fold paralysis, the vocal folds are unable to open, which causes narrowing and blockage of the airway. The amount of space left between the immobile vocal folds determines the degree of the blockage. There is almost always noisy breathing and breathlessness during activity.
What is unilateral vocal fold paresis?
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.
Is vocal cord paresis permanent?
This usually happens within the first year. Sometimes, the vocal cord is permanently paralyzed. You may need treatment if you have problems swallowing or if your voice is hoarse.
How do you cure paresis vocal cords?
Treatment may include voice therapy, bulk injections, surgery or a combination of treatments. In some instances, you may get better without surgical treatment. For this reason, your doctor may delay permanent surgery for at least a year from the beginning of your vocal cord paralysis.
What causes general paresis?

What causes vocal paresis?
Possible causes include nerve damage during surgery, viral infections and certain cancers. Treatment for vocal cord paralysis usually involves surgery, and sometimes voice therapy.
What is the recurrent laryngeal nerve?
Recurrent laryngeal nerve. The recurrent laryngeal nerve (RLN), also known as the inferior laryngeal nerve, is a branch of the vagus nerve (CN X) which has a characteristic loop around the right subclavian artery on the right and the aortic arch on the left before returning up to achieve the tracheoesophageal groove and then the larynx .
What causes superior laryngeal nerve paresis and paralysis?
Superior laryngeal nerve paresis and paralysis are relatively common but often difficult to diagnose with certainty. They are most commonly caused by viral infections, though other etiologies must be considered. A thorough history and physical examination, including strobovideolaryngoscopy and laryn …
What is vocal cord paresis and what causes it?
From Wikipedia, the free encyclopedia Vocal cord paresis, also known as recurrent laryngeal nerve paralysis or vocal fold paralysis, is an injury to one or both recurrent laryngeal nerves (RLNs), which control all muscles of the larynx except for the cricothyroid muscle. The RLN is important for speaking, breathing and swallowing.
What causes left recurrent laryngeal nerve palsy with cardiovascular origin?
Although it was originally identified in patients with left atrial enlargement, the definition has expanded to include aneurysms of the aortic arch, pulmonary hypertension due to mixed connective tissue disease, or aberrant subclavian artery syndrome among other causes of left recurrent laryngeal nerve palsy with cardiovascular origin.
