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.
The recurrent laryngeal nerve (RLN) is a branch of the vagus nerve (cranial nerve X) that supplies all the intrinsic muscles of the larynx, with the exception of the cricothyroid muscles. There are two recurrent laryngeal nerves, right and left.
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 ...

Neck pain causes can be anything from sleeping in an uncomfortable position to serious neurological concerns. Experts explain causes, diagnosis, and treatments.
Laryngospasm is characterized by involuntary spasms of the laryngeal muscles. It is associated with difficulty or inability to breathe or speak, retractions, a feeling of suffocation, which may be followed by hypoxia-induced loss of consciousness. [2] It may be followed by paroxysmal coughing and in partial laryngospasms, a stridor may be heard ...
Recurrent laryngeal nerve avulsion is a more drastic removal of sections of the nerve, [46] and has positive outcomes of 80% at three years. [42] SLAD-R is effective specifically for adductor spasmodic dysphonia, for which it has shown good outcomes in about 80% of people at 8 years. [ 40 ]
Sensory innervation to the glottis and laryngeal vestibule is by the internal branch of the superior laryngeal nerve. The external branch of the superior laryngeal nerve innervates the cricothyroid muscle. Motor innervation to all other muscles of the larynx and sensory innervation to the subglottis is by the recurrent laryngeal nerve. While ...
