Partial paralysis; partial loss of paralysis de pliegue vocal input to a muscle, resulting in muscle weakness Paralysis Complete loss of nerve input to a muscle resulting in complete loss of muscle function Laryngeal Electromyography LEMG Test that measures electrical signals of nerve inputs to muscles Recurrent Laryngeal Nerve RLN Branch of vagus nerve to voice box muscles that open and close vocal folds Superior Laryngeal Nerve SLN Glossary In Brief Partial paresis or complete loss paralysis of nerve function to voice box muscles results in abnormal vocal fold paralysis de pliegue vocal, affects the ability to speak and sing and, in some cases, also breathe and swallow.


Attempts to compensate for loss of muscle function, often leads to voice tiring after prolonged use vocal fatigue. Interruption of the nerve input to voice box muscles may be temporary or permanent, partial or complete, and may affect one or more voice box muscles.

Vocal cord paresis - Wikipedia

A Continuum Vocal fold paresis and paralysis comprise a range — from mild to severe — of abnormal voice box muscle functions due to varying degrees of abnormal nerve input. Paresis A Frequently Missed Cause of Voice Disorders Paresis of voice box muscles is often missed as the cause of a voice disorder because patient complaints can be very mild.

For example, a patient with vocal fold paresis may only notice voice tiring after use, often at the end of the day vocal fatigue. Identification of Paresis and Paralysis Needs to Be Carefully Done Absence of vocal fold movement vocal fold immobility is highly suggestive of vocal fold paralysis paralysis de pliegue vocal may also be due to other causes — hence thorough medical evaluation is necessary.

Likewise, if the vocal folds do move, it does not eliminate nerve impairment as a cause of the voice disorder since vocal fold paralysis de pliegue vocal may be present.

Voice assessment is necessary to plan and estimate paralysis de pliegue vocal success of a possible speech therapy. Each dimension will receive a severity rating from 0 not present to 3 severe. This allows the S-LP to make a judgment about the overall severity of the voice quality.

The CAPE-V is used in a similar manner, rating of the dimensions of voice quality on a subjective scale from 0—, and using this to determine an overall severity score.


In the presence of neural lesions with unknown cause, a thorough ENT endoscopy [9] with paralysis de pliegue vocal imaging techniques computed tomography CT of the chest, particularly in the case of left-sided paralyses, and magnetic resonance imaging MRI of the neck including the base of the skull and the brain, ultrasound examination of the neck are performed to exclude tumors along the laryngeal nerves.

When tumor formation is suspected, parts of the hypopharynx and the upper esophagus and passive mobility of the arytenoid cartilage are endoscopically examined under anesthesia. Stroboscopy [9] [11] and voice assessment are important to establish an individual treatment plan to improve the voice.

paralysis de pliegue vocal


Breathing tests spirometrybody plethysmography are used to measure impairment of respiratory flow through the larynx, particularly in patients with bilateral paralysis. Electromyography of the larynx muscles larynx EMG[1] [12] which measures the electrical activity of the larynx muscles via thin paralysis de pliegue vocal electrodes, allows better differentiation between a neural lesion and other causes of impaired mobility of the vocal fold and localization of the lesion along the nerve.

Vocal Cord Paralysis

The larynx EMG can, within limits, provide a paralysis de pliegue vocal of the development of a recurrent laryngeal nerve paralysis. Patients with a poor chance of healing can be identified at an early stage. Paralysis de pliegue vocal, this advanced examination technique is not available in all treatment centers.

The treating physician must view all examination results combined [11] and establish an individual diagnosis and treatment plan for each patient.

Classification[ edit ] Vocal fold paresis refers to a partial loss of input to the nerve of the vocal folds.
