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.
Vocal cord dysfunction (VCD) is a condition affecting the vocal cords. [1] It is characterized by abnormal closure of the vocal folds, which can result in significant difficulties and distress during breathing, particularly during inhalation. [1] Due to the similarity in symptoms, VCD attacks are often mistaken for asthma attacks or laryngospasms.
This is the sole muscle responsible for opening the vocal cords, and paralysis may cause difficulty breathing during physical activity. [19] Injury to both the right and left nerve may result in more serious damage, such as the inability to speak .
Mayo Clinic defines vocal cord paralysis as “a condition that causes the loss of control of the muscles that control the voice” when the larynx is disrupted. Causes of this form of paralysis ...
The paralyzed vocal cord may rest close to or far from the midline. An extremely laterally positioned vocal cord can result in a large posterior glottal gap - an opening between the two vocal cords even when the functioning vocal cord is fully medialized. Vocal cord injection is ineffective for closing a large glottal gap. [6]
Voice disorders [1] are medical conditions involving abnormal pitch, loudness or quality of the sound produced by the larynx and thereby affecting speech production. These include:
One or both vocal folds may be effectively paralyzed, or have diminished function. If a vocal fold is stuck in an adducted or closed position, the voice will be harsh and low in volume. A vocal fold stuck in an abducted or open position may cause breathiness and low volume. Listen for vocal flutter and diplophonia.
Eventually she was diagnosed with a partially paralyzed vocal cord and underwent surgery in August. Husband Brad Paisley and their two teen sons helped support her along the way.
