What is laryngeal nerve palsy?
Laryngeal nerve palsy: Paralysis of the larynx (voice box) caused by damage to the recurrent laryngeal nerve or its parent nerve, the vagus nerve, which originates in the brainstem and runs down to the colon.
What do the recurrent laryngeal nerve loop around?
The recurrent laryngeal nerve (RLN), also known as the inferior laryngeal nerve, is a branch of the vagus nerve (CN X) which has a characteristic loop around the right subclavian artery on the right and the aortic arch on the left before returning up to achieve the tracheoesophageal groove and then the larynx.

How do you treat a recurrent laryngeal nerve injury?
The treatment methods include the medicines (neurotrophic medicines, glucocorticoids and vasodilators); ultrashort wave therapy, acupuncture and moxibustion and others; voice training, vocal cord injection and others; reinnervation methods of the unilateral RLN injury (including RLN decompression, end to end …
Is vocal cord paresis permanent?
In other cases, the uninjured, moving vocal cord takes over for the vocal cord that’s paralyzed. This usually happens within the first year. Sometimes, the vocal cord is permanently paralyzed. You may need treatment if you have problems swallowing or if your voice is hoarse.
Where does the recurrent laryngeal nerve come from?
The recurrent laryngeal nerve (RLN) is derived from the vagus trunk as it enters the thorax. The left RLN curves below and behind the aortic arch at the level of the ligamentum arteriosum. The right RLN loops under the subclavian artery.
Why is the left recurrent laryngeal nerve so situated?
On the left, the recurrent laryngeal nerve has a longer course to the neck than the right side. This is because it hooks under the left sixth arch artery which persists in extra-uterine life as the ductus arteriosus, a fibrous remnant.
How do you know if you have a recurrent laryngeal nerve?
The Tubercle of Zuckerkandl marks the posterolateral aspect of the thyroid lobe and is most often found lateral to the recurrent laryngeal nerve. The tubercle can be found in 80% of thyroids and when found can lead directly to the recurrent laryngeal nerve, as 93% of the nerves are found medial to this tubercle.
How long does it take for larynx to heal?
You won’t be able to eat until your throat has healed, which for most people takes at least 1 or 2 weeks. While your throat heals, you’ll need to be fed through a tube that’s passed through your nose and into your stomach.

Although many procedures have been introduced to prevent the nerve injury, still the incidence of recurrent laryngeal nerve palsy varies between 1.5-14%.
What is non recurrent laryngeal nerve?
A nonrecurrent laryngeal nerve (NRLN) is a rare anatomical variation in which the nerve enters the larynx directly from the cervical vagus nerve, without descending to the thoracic level . It has been reported in 0.3-0.8% of the population on the right side, being extremely rare on the left side (0.004%) .
