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 intrinsic muscles of the larynx except for the cricothyroid muscle. The RLN is important for speaking, breathing and swallowing.
Damage to these nerves results in vocal cord paralysis - the reduced mobility and inability to adduct one or both vocal cords. Many cases of vocal cord paralysis result from trauma during surgery. [2] Symptoms include hoarseness of voice, difficulty projecting, difficulty swallowing, and throat pain. [citation needed]
The recurrent laryngeal nerves supply sensation to the larynx below the vocal cords, give cardiac branches to the deep cardiac plexus, and branch to the trachea, esophagus and the inferior constrictor muscles. The posterior cricoarytenoid muscles, the only muscles that can open the vocal folds, are innervated by this nerve.
A vocal fold stuck in an abducted or open position may cause breathiness and low volume. Listen for vocal flutter and diplophonia. Having both vocal folds stuck in an abducted position creates a breathy voice, with potential inspiratory stridor. Having both vocal folds stuck in an adducted or closed position compromises the airway significantly.
Before finally getting the August surgery to correct the underlying problem — a partial paralysis of her left vocal cord — she discovered a new inner strength as she relentlessly searched for ...
The open position of the vocal folds also allows air to escape from the lungs during speech. As a result, the voices of these individuals often sound weak, quiet, and breathy or whispery. As with adductor spasmodic dysphonia, the spasms are often absent during activities such as laughing or singing, but singers can experience a loss of range or ...
MTD is a unifying diagnosis for a previously poorly categorized disease process. It allows for the diagnosis of dysphonia caused by many different etiologies and can be confirmed by history, physical exam, laryngoscopy and videostroboscopy, a technique that allows for the direct visualization of the larynx, vocal cords, and vocal cord motion.
