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.
Tucker syndrome, also known as Ptosis-vocal cord paralysis syndrome, is a very rare genetic disorder which is characterized by congenital bilateral ptosis and (also congenital and bilateral) recurrent laryngeal nerve paresis. [1] [2] [3] Additional findings include short stature. [4] It was described in a small 2-generation family (a man and ...
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.
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]
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.
Experts don’t know the exact cause of transverse myelitis, a rare neurological condition that happens when someone’s spinal cord becomes inflamed. If oxygen can’t reach the spinal cord ...
First identified in California in 1962, EV-D68 is worrisome because, in rare cases, it can harm the spinal cord and cause a condition known as acute flaccid myelitis — which causes muscles to ...
Due to its low frequency of occurrence, more common causes of hoarseness should be considered when suspecting left recurrent laryngeal nerve palsy (LRLN).. When considering cardiovocal syndrome, the most common historical cause is a dilated left atrium due to mitral stenosis, but other causes, including pulmonary hypertension, [2] thoracic aortic aneurysms, an enlarged pulmonary artery [3] and ...
